What APRA CPS 234 Actually Requires

APRA CPS 234 is Australia’s information security standard for prudentially regulated entities, and it is not optional. If you operate as a general insurer, life insurer, or health insurer in Australia, APRA expects you to meet CPS 234. This is not a guideline. It is a binding prudential standard, and your board, audit committee, and regulators will measure your compliance against it.

The standard itself sits within the broader APRA information security requirements for all APRA-regulated entities framework. CPS 234 was released in 2019 and has been tightened progressively. The core intent is straightforward: information security must be treated as a business risk, managed by the board, and embedded in every operational decision. Not buried in IT.

APRA CPS 234 covers seven core areas:

• Governance and accountability: Your board must own information security risk. Not delegate it entirely to the CTO or Chief Information Security Officer (CISO).
• Risk management: You must identify, assess, and mitigate information security risks using a documented, repeatable process.
• Personnel security: Your team must be vetted, trained, and held accountable for security outcomes.
• Access control: Who gets what access, when, and why. Documented. Reviewable.
• Cryptography: Data at rest and in transit must be encrypted using industry-standard algorithms.
• Operational resilience: Your systems must be designed to survive and recover from incidents.
• Incident management and reporting: You must detect breaches, respond to them, and report them to APRA and affected parties within strict timeframes.

The standard also references ISO/IEC 27001 Information Security Management Systems as a useful baseline for control design, though CPS 234 is stricter in places and more prescriptive about governance. Many Australian insurers pursue ISO 27001 certification in parallel with CPS 234 compliance, which is sensible—the controls overlap significantly, and a single audit can often satisfy both frameworks.

Why does this matter to you right now? Because APRA has made it clear that information security is non-negotiable. Breaches, poor incident response, inadequate encryption, or weak governance will result in regulatory action, enforcement, and reputational damage. The cost of remediation after a breach or audit failure is orders of magnitude higher than the cost of building controls upfront.

The Insurance-Specific Landscape

Insurance organisations face a specific set of pressures when implementing CPS 234. Unlike banks, which often have decades of compliance infrastructure, many insurers—especially mid-market and smaller players—are building security governance from the ground up or retrofitting legacy systems that were never designed with security as a first-class concern.

The insurance sector also handles some of the most sensitive personal and financial data in the Australian economy. Your customers’ health records, claim history, personal circumstances, and payment details are all stored and processed by your systems. A breach is not just a regulatory problem; it is a customer trust problem and a reputational crisis.

APRA’s expectations for insurers are clear: you must treat information security as a core business function, not an IT checkbox. This means:

• Your board must receive regular, clear reporting on information security risk and control effectiveness.
• Your executive team must allocate budget and resources to security, not just compliance.
• Your operational teams must understand that security is part of their job, not something imposed by IT.
• Your technology decisions—cloud migration, new software, outsourcing—must be evaluated through a security lens first.

Many insurers we work with at PADISO’s AI for Insurance Sydney practice are also deploying AI and automation into claims, underwriting, and conduct risk monitoring. This adds a new layer of complexity. If your AI model makes decisions about customer claims or pricing, and that model is compromised or manipulated, the consequences are severe. CPS 234 requires you to think about information security across your entire operating model, including new technologies.

The good news is that CPS 234 is not a moving target. The standard has been stable since 2019. APRA has published guidance, worked examples, and has been relatively consistent in its expectations. If you build controls to the standard today, they will remain relevant. The challenge is not understanding what to do; it is doing it thoroughly and documenting it so that auditors can verify compliance.

---

Core Control Pillars You Cannot Skip

CPS 234 is built on seven pillars, but in practice, insurance organisations must focus on five areas where the standard is most specific and most heavily weighted in audits.

Governance and Board Accountability

Your board must own information security risk. This is not a technicality. APRA expects the board to:

• Approve the information security policy and strategy.
• Receive regular reports on information security incidents, risk assessments, and control effectiveness.
• Understand the link between information security risk and business risk.
• Hold management accountable for security outcomes.

In practice, this means your board papers must include a standing information security agenda item. Not quarterly. Monthly or bi-monthly. The board must see evidence that:

• Incidents are being tracked, investigated, and resolved.
• Risk assessments are being conducted and documented.
• Controls are being tested and validated.
• Training and awareness programmes are running and being measured.

Many insurers make the mistake of delegating security entirely to the CISO or IT director, then wondering why the board cannot articulate the organisation’s security posture. APRA will ask the board directly about information security risk. If the board cannot answer confidently, that is a finding.

Risk Management and Assessment

You must have a documented information security risk management process. This means:

• Identifying all information assets (databases, systems, applications, data stores).
• Assessing the risk to each asset (confidentiality, integrity, availability).
• Identifying controls that mitigate those risks.
• Testing controls to confirm they work.
• Documenting the entire process so that it is repeatable and auditable.

Many insurers use a risk register to track this. The register should include:

• Asset name and description.
• Risk category (data breach, system failure, insider threat, etc.).
• Risk rating (high, medium, low) based on likelihood and impact.
• Mitigating controls (technical, operational, governance).
• Control owner and testing schedule.
• Evidence of control testing.

APRA expects this to be a living document. If you deploy a new system, you must update the risk register. If a control fails testing, you must remediate and re-test. If a new threat emerges, you must assess it and adjust controls accordingly.

Personnel Security and Vetting

Your team must be vetted before they access sensitive systems. This includes:

• Background checks for new hires.
• Ongoing vetting for staff with access to customer data or critical systems.
• Training on information security obligations.
• Clear consequences for security breaches or policy violations.

APRA expects you to have a policy that covers:

• Pre-employment vetting (criminal history, reference checks, identity verification).
• Periodic re-vetting for staff in sensitive roles.
• Termination procedures that ensure access is revoked immediately.
• Confidentiality agreements and non-disclosure obligations.
• Training on information security, data handling, and breach reporting.

Many insurers underestimate the importance of personnel security. A single disgruntled employee with access to customer data can cause enormous damage. APRA expects you to have controls that make this difficult.

Access Control and Privilege Management

You must control who has access to what, and why. This is one of the most heavily tested areas in CPS 234 audits. APRA expects:

• A documented access control policy that defines roles, responsibilities, and approval workflows.
• A system for requesting, approving, and provisioning access (often called Identity and Access Management, or IAM).
• Regular reviews of access to ensure only authorised personnel have the access they need.
• Logging and monitoring of access to sensitive systems and data.
• Immediate revocation of access when staff leave or change roles.

In practice, this means:

• You need a system (often called a PAM or Identity platform) that tracks who has access to what.
• You need a quarterly or semi-annual access review process where managers confirm that their team members should still have the access they have.
• You need audit logs that show who accessed what, when, and from where.
• You need alerts for suspicious access patterns (e.g., access from unusual locations, access outside normal hours, bulk data downloads).

Many insurers struggle with this because they have legacy systems that do not have robust access controls built in. If you are running systems from the 1990s or 2000s, you may not have the ability to log access or enforce role-based access control. This is a major gap, and APRA will flag it.

Cryptography and Data Protection

APRA expects data at rest and in transit to be encrypted using industry-standard algorithms. This includes:

• Customer data stored in databases must be encrypted (AES-256 or equivalent).
• Data transmitted over the internet must use TLS 1.2 or later.
• Encryption keys must be managed securely (not hardcoded in applications, not stored in plain text).
• Key rotation must be implemented and documented.

Many insurers think encryption is a binary: either it is on or off. APRA is more granular. The standard requires:

• A cryptography policy that defines which algorithms are acceptable, how keys are managed, and how encryption is implemented.
• Evidence that encryption is actually in place (configuration reviews, code reviews, penetration testing).
• A key management process that ensures keys are stored securely, rotated regularly, and decommissioned properly when no longer needed.

If you are using cloud infrastructure (AWS, Azure, GCP), encryption is often easier because the cloud provider handles much of the key management. But you still need to ensure that encryption is enabled, keys are managed according to your policy, and audit logs show that encryption is working.

---

Building Your Incident Response and Breach Notification Capability

Incident response is where CPS 234 gets very specific, and it is also where many insurers struggle. APRA expects you to:

• Detect breaches quickly (ideally within hours or days, not weeks).
• Respond to breaches in a structured, documented way.
• Notify APRA and affected customers within strict timeframes.
• Learn from breaches and improve controls.

APRA’s guidance on breach notification is unambiguous. If you suffer a breach that could cause serious harm to customers (financial loss, identity theft, reputational damage), you must notify APRA and the affected customers within 30 days. For some types of breaches, APRA expects notification within 10 days. This is not a suggestion; it is a requirement.

The challenge is that many insurers do not have the detection capability to identify breaches quickly. If your systems are not monitored, you may not know a breach has occurred until weeks or months later, when a customer reports suspicious activity or a third party alerts you. By then, the 30-day window may have passed, and you are in breach of CPS 234.

Building incident response capability requires:

Detection and Monitoring

You need systems in place to detect breaches. This includes:

• Security Information and Event Management (SIEM) tools that aggregate logs from all systems and alert on suspicious activity.
• Intrusion Detection Systems (IDS) that monitor network traffic for signs of compromise.
• Endpoint Detection and Response (EDR) tools that monitor staff computers and servers for malware or suspicious behaviour.
• Data Loss Prevention (DLP) tools that monitor for unauthorised data exfiltration.

Many insurers start with a basic SIEM (often based on open-source tools like ELK Stack or Splunk) and build from there. The key is to have visibility into what is happening on your systems so that you can detect breaches quickly.

Incident Response Planning

You need a documented incident response plan that defines:

• Who is on the incident response team (CISO, IT director, legal, communications, customer service).
• How incidents are reported and escalated.
• How the incident is investigated and contained.
• How affected customers are notified.
• How APRA is notified.
• How the incident is documented and lessons are learned.

APRA expects this plan to be tested regularly (at least annually) through tabletop exercises or simulations. This ensures that when a real breach occurs, your team knows what to do.

The ACSC: Incident response planning guidance provides a good framework. The OAIC: Data breach preparedness and response guidance is also essential for understanding privacy obligations around breach notification.

Breach Notification and APRA Reporting

When a breach occurs, you must:

• Notify APRA within 10 days if the breach is serious.
• Notify affected customers within 30 days (or sooner if the risk is high).
• Keep detailed records of the breach, the investigation, and the response.
• Conduct a post-incident review to identify what went wrong and how to prevent it in the future.

APRA has published detailed guidance on breach notification. The key points are:

• A “serious breach” is one that could cause serious harm to customers (financial loss, identity theft, loss of privacy).
• Notification must include details of what happened, what data was compromised, what the customer should do, and what you are doing to prevent it in the future.
• You must be able to demonstrate that you acted promptly and in good faith.

Many insurers underestimate the reputational and financial cost of a breach. A single incident can result in millions of dollars in regulatory fines, customer compensation, forensic investigation, and reputational damage. The cost of building detection and response capability upfront is a fraction of the cost of dealing with a breach after the fact.

---

Governance, Accountability and Board Readiness

CPS 234 places significant emphasis on governance and board accountability. This is not just about having the right policies and procedures; it is about ensuring that the board understands information security risk and holds management accountable for managing it.

In practice, this means:

Board Reporting and Oversight

Your board must receive regular, clear reporting on information security. This should include:

• A dashboard of key metrics: number of incidents, severity, resolution time, control test results.
• A summary of significant risks and how they are being managed.
• A report on any breaches or near-misses.
• A report on the effectiveness of controls (what is working, what needs improvement).
• A report on training and awareness activities.

Many boards are uncomfortable with information security because they do not understand it or do not see it as their responsibility. Your job is to translate security into business terms. Instead of talking about “zero-day vulnerabilities,” talk about “risks that could result in customer data theft and regulatory fines.” Instead of talking about “penetration testing,” talk about “testing our defences to find weaknesses before attackers do.”

The Australian Institute of Company Directors: Cyber security guide for boards provides excellent guidance on what boards should be asking about security.

Accountability and Responsibility

Your organisation must have clear lines of accountability for information security. This means:

• Designating a Chief Information Security Officer (CISO) or equivalent who is responsible for information security strategy and execution.
• Ensuring the CISO has sufficient authority and resources to implement controls.
• Holding the CISO and business leaders accountable for security outcomes (through KPIs, remuneration, performance reviews).
• Documenting roles and responsibilities so that everyone knows who is accountable for what.

Many organisations make the mistake of treating security as an IT problem. APRA expects security to be a business problem that IT helps solve. This means:

• The Chief Executive Officer (CEO) and Chief Financial Officer (CFO) must understand and own information security risk.
• The Chief Operating Officer (COO) must ensure that information security is embedded in operational processes.
• The Chief Risk Officer (CRO) must integrate information security risk into the enterprise risk management framework.
• The General Counsel must ensure that information security is aligned with legal and regulatory obligations.

Policy and Documentation

You must have documented policies that cover:

• Information security strategy and objectives.
• Information security governance and accountability.
• Risk management and assessment.
• Personnel security and vetting.
• Access control and privilege management.
• Cryptography and data protection.
• Incident management and breach notification.
• Third-party risk management.
• Business continuity and disaster recovery.

APRA does not prescribe the exact content of these policies, but it expects them to be comprehensive, documented, approved by the board, and communicated to all staff. Many insurers make the mistake of writing policies but not implementing them. APRA will ask for evidence that policies are being followed.

---

Technology Controls: The Practical Build

Once you have governance and risk management in place, you need to implement technology controls that actually prevent and detect breaches. This is where many insurers struggle because they have legacy systems that were not designed with security in mind.

Network Security and Segmentation

Your network must be segmented so that a compromise in one part of the network does not spread to other parts. This means:

• Separating customer-facing systems from internal systems.
• Separating development and testing systems from production systems.
• Using firewalls and network access control lists to restrict traffic between segments.
• Monitoring traffic between segments for suspicious activity.

Many insurers run flat networks where any system can communicate with any other system. This is a major security risk. APRA expects network segmentation.

Application Security

Your applications must be built with security in mind. This includes:

• Code reviews to identify security vulnerabilities before code is deployed.
• Static and dynamic security testing (SAST and DAST) to find vulnerabilities in running code.
• Dependency scanning to identify vulnerable third-party libraries.
• Secure coding practices (input validation, output encoding, parameterised queries to prevent SQL injection).
• Regular patching and updates to fix known vulnerabilities.

Many insurers use legacy applications that were built before security best practices were widely understood. These applications may be vulnerable to common attacks like SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). If you cannot fix the application, you may need to retire it or wrap it with additional security controls.

Endpoint Security

Your staff computers and servers must be protected. This includes:

• Antivirus and anti-malware software.
• Endpoint Detection and Response (EDR) tools that monitor for suspicious behaviour.
• Disk encryption so that data is protected if a device is lost or stolen.
• Mobile device management (MDM) if staff use personal devices to access company data.
• Regular patching and updates.

Cloud Security

If you use cloud infrastructure (AWS, Azure, GCP), you must:

• Ensure that data is encrypted in transit and at rest.
• Implement strong access controls (identity and access management).
• Monitor cloud resources for misconfiguration or suspicious activity.
• Ensure that cloud providers meet your security requirements (SOC 2 certification, for example).
• Have a data residency strategy that ensures customer data is stored in Australia (or elsewhere as required).

Many insurers are moving to cloud to reduce infrastructure costs and improve agility. Cloud can be more secure than on-premises infrastructure if configured correctly, but it requires a different approach to security. You cannot assume that the cloud provider is handling security for you. You must verify that security controls are in place and working.

Common Pitfalls and How to Avoid Them

After working with dozens of Australian insurers on CPS 234 compliance, we have seen common patterns in what goes wrong. Here are the pitfalls to avoid.

Pitfall 1: Treating Compliance as a Checkbox

Many insurers approach CPS 234 as a compliance exercise: build the controls, pass the audit, move on. This is a mistake. APRA is looking for evidence that controls are actually working, not just documented. If you have a control that is documented but not implemented, or implemented but not tested, APRA will flag it.

The solution is to treat security as an ongoing operational discipline. Build controls, test them regularly, measure their effectiveness, and continuously improve them. Use metrics like mean time to detect (MTTD) and mean time to respond (MTTR) to track how quickly you can identify and respond to incidents.

Pitfall 2: Weak Access Control and Privilege Management

Many insurers have poor visibility into who has access to what. Staff accumulate access over time as they change roles, and old access is never revoked. Contractors and vendors have access that is never reviewed. This creates a huge security risk.

The solution is to implement a robust identity and access management (IAM) system. Require all access requests to go through an approval workflow. Conduct quarterly access reviews where managers confirm that their team members should still have the access they have. Revoke access immediately when staff leave or change roles. Log all access and monitor for suspicious activity.

Pitfall 3: Inadequate Incident Detection and Response

Many insurers do not have the capability to detect breaches quickly. They rely on external parties (customers, security researchers) to alert them to breaches. By the time they realise a breach has occurred, weeks or months may have passed. This makes it impossible to meet the 30-day breach notification requirement.

The solution is to implement detection capability. Start with basic log aggregation and alerting (SIEM). Gradually add more sophisticated tools like IDS, EDR, and DLP. Test your incident response plan regularly through tabletop exercises. Make sure your incident response team knows what to do when a breach occurs.

Pitfall 4: Poor Encryption Implementation

Many insurers have encryption policies but weak implementation. Encryption may be enabled on some systems but not others. Encryption keys may be stored insecurely. Key rotation may not be happening. This creates a false sense of security.

The solution is to audit your encryption implementation. Use configuration management tools to ensure encryption is enabled on all systems that store sensitive data. Implement a key management system that ensures keys are stored securely and rotated regularly. Test encryption regularly to ensure it is working.

Pitfall 5: Inadequate Vendor and Third-Party Risk Management

Many insurers outsource critical functions (claims processing, customer service, data storage) to vendors. If a vendor is compromised, your customers’ data is at risk. But many insurers do not adequately assess vendor security or monitor vendor compliance with security requirements.

The solution is to implement a vendor risk management process. Before engaging a vendor, assess their security posture (ask for SOC 2 reports, ISO 27001 certification, or conduct a security questionnaire). Include security requirements in vendor contracts. Conduct regular audits of vendors to ensure they are meeting security requirements. Have a plan to respond if a vendor is compromised.

Pitfall 6: Weak Board Engagement and Reporting

Many organisations do not adequately communicate information security risk to the board. The board does not understand the risks, does not allocate sufficient resources, and does not hold management accountable. When APRA asks the board about security, the board cannot answer confidently.

The solution is to make board reporting a priority. Translate security into business terms. Show the board what could go wrong (customer data theft, regulatory fines, reputational damage) and what you are doing to prevent it. Give the board metrics that they can understand and track. Make sure the board knows that information security is a business risk, not just an IT issue.

The Real Audit Timeline and What to Expect

APRA conducts regular supervisory reviews of insurers’ compliance with CPS 234. The timeline and scope of these reviews vary, but here is what you can expect.

Audit Notification and Planning

APRA will typically notify you 4-8 weeks before an audit that they plan to conduct a CPS 234 review. They will ask you to provide documentation of your information security governance, policies, risk assessments, and control testing. They will also ask for evidence of board oversight and management accountability.

During this planning phase, you should:

• Gather all relevant documentation (policies, risk registers, audit logs, incident reports, training records).
• Identify any gaps in documentation or controls.
• Prepare your team for the audit (brief them on what to expect, what questions they might be asked).
• Designate a single point of contact for the audit team.

On-Site Audit

The audit itself typically takes 1-2 weeks. APRA will:

• Interview key personnel (CEO, CISO, IT director, business leaders, frontline staff).
• Review documentation (policies, risk assessments, control testing, incident reports).
• Test controls (review access logs, test encryption, check that patches are being applied).
• Observe processes (attend risk assessment meetings, incident response exercises, access review meetings).

During the on-site audit, you should:

• Ensure that key personnel are available and prepared.
• Provide all requested documentation promptly.
• Be honest about gaps and weaknesses. APRA will find them anyway, and honesty is better than trying to hide things.
• Ask clarifying questions if you do not understand what APRA is looking for.

Audit Findings and Remediation

After the audit, APRA will issue a report with findings. Findings are typically categorised as:

• Critical: A control is missing or not working at all. This poses a serious risk to the organisation.
• High: A control exists but has significant weaknesses. This poses a material risk.
• Medium: A control exists but could be improved. This poses a moderate risk.
• Low: A minor improvement that would enhance security.

For each finding, APRA will expect you to provide a remediation plan with specific actions, timelines, and accountability. You will typically have 30-90 days to remediate critical findings, 90-180 days for high findings, and longer for medium and low findings.

Ongoing Supervision

APRA does not just conduct an audit and then leave you alone. They will monitor your remediation progress and may conduct follow-up audits to verify that findings have been addressed. They may also conduct targeted reviews if they become aware of a breach or other incident.

In practice, this means you should treat CPS 234 compliance as an ongoing operational discipline, not a one-time audit exercise. Build controls, test them regularly, measure their effectiveness, and continuously improve them.

Getting Started: Your 90-Day Roadmap

If you are just starting your CPS 234 compliance journey, here is a practical 90-day roadmap to get you moving.

Days 1-30: Assessment and Planning

Week 1-2: Current State Assessment

• Conduct an inventory of all information assets (systems, databases, applications, data stores).
• Document current governance and accountability structures.
• Review existing policies and procedures.
• Identify gaps in documentation, controls, and capabilities.

Week 3-4: Roadmap Development

• Prioritise gaps based on risk and effort.
• Develop a detailed remediation roadmap with milestones and owners.
• Identify resource requirements (people, budget, tools).
• Brief the board on the roadmap and secure buy-in.

Consider engaging a partner like PADISO’s AI Advisory Services to help with the assessment. An independent assessment often identifies gaps that internal teams miss, and it provides credibility with APRA and the board.

Days 31-60: Quick Wins and Foundation Building

Week 5-6: Governance and Accountability

• Designate a CISO or equivalent.
• Establish an information security committee with representation from key business areas.
• Develop an information security policy and get board approval.
• Establish board reporting on information security (monthly or bi-monthly).

Week 7-8: Risk Assessment and Documentation

• Conduct a risk assessment of all information assets.
• Develop a risk register that documents risks and mitigating controls.
• Document access control policies and implement a basic access review process.
• Develop an incident response plan and conduct a tabletop exercise.

Days 61-90: Control Implementation and Testing

Week 9-10: Technology Controls

• Implement or upgrade SIEM for log aggregation and alerting.
• Audit encryption implementation and develop a key management process.
• Implement or upgrade endpoint security tools.
• Conduct a network security assessment and develop a network segmentation plan.

Week 11-12: Testing and Validation

• Conduct control testing to verify that controls are working.
• Document test results and evidence of control effectiveness.
• Identify any control failures and develop remediation plans.
• Conduct a second tabletop incident response exercise.
• Prepare for potential APRA audit by gathering and organising documentation.

This 90-day roadmap is aggressive but achievable if you have executive commitment and adequate resources. The key is to start with governance and risk assessment, then build controls based on the risks you have identified.

---

Next Steps and Getting Support

CPS 234 compliance is not a one-time project. It is an ongoing operational discipline that requires sustained commitment from the board, executive team, and all staff.

If you are serious about compliance, here are the next steps:

1. Assess Your Current State

Conduct an honest assessment of where you are today. What controls are in place? What is working? What is missing? What is the risk if you do not remediate gaps? An independent assessment provides credibility and often identifies gaps that internal teams miss.

If you want a structured, fixed-scope assessment, consider PADISO’s AI Quickstart Audit, which is a two-week diagnostic that tells you where you are, what to ship first, and what 90 days could unlock.

2. Develop a Roadmap

Based on your assessment, develop a detailed roadmap with milestones, owners, and timelines. Prioritise based on risk and effort. Get board buy-in and secure the resources you need.

3. Implement Controls

Start with governance and risk assessment, then build technology controls based on the risks you have identified. Test controls regularly and measure their effectiveness.

4. Engage with APRA

If APRA has notified you of an upcoming audit, be prepared. Gather documentation, brief your team, and be honest about gaps and weaknesses. APRA is more interested in seeing a credible remediation plan than in finding perfect compliance.

5. Continuous Improvement

Treat CPS 234 compliance as an ongoing operational discipline. Measure control effectiveness, identify improvement opportunities, and continuously enhance your security posture.

Getting Help

CPS 234 compliance is complex and requires expertise across governance, risk, technology, and operations. Many organisations benefit from external support, especially for the initial assessment and roadmap development.

If you are an Australian insurer looking to build or improve your CPS 234 compliance programme, consider reaching out to PADISO’s Insurance AI Sydney team. We specialise in helping Australian general, life, and health insurers build APRA and LIF-compliant operations, including CPS 234 compliance. We can help you assess your current state, develop a remediation roadmap, implement controls, and prepare for audit.

We also offer Fractional CTO & CTO Advisory in Sydney for organisations that need ongoing technical leadership and governance support. And if you are deploying AI or automation into your operations, we can help you ensure that these new technologies are deployed securely and in compliance with CPS 234.

Alternatively, if you are looking to build a comprehensive security and compliance programme that covers CPS 234, SOC 2, and ISO 27001, PADISO offers Security Audit support via Vanta to help you get audit-ready in weeks rather than months.

The Bottom Line

APRA CPS 234 is not optional. It is a binding prudential standard that applies to all Australian insurers. The cost of building compliance is a fraction of the cost of dealing with a breach or regulatory enforcement action. Start with an honest assessment of where you are, develop a realistic roadmap, get board buy-in, and build controls systematically. Test them regularly, measure their effectiveness, and continuously improve. Treat information security as a business risk, not an IT checkbox. If you do this, you will not just pass APRA audits—you will build a security posture that actually protects your customers and your business.

---

Summary

APRA CPS 234 is Australia’s information security standard for prudentially regulated insurers. It requires organisations to treat information security as a business risk, embed it in governance and operations, and implement controls across governance, risk management, personnel security, access control, cryptography, incident response, and operational resilience.

The standard is not a moving target—it has been stable since 2019. The challenge is not understanding what to do; it is doing it thoroughly and documenting it so that auditors can verify compliance.

Key takeaways:

• Governance matters: Your board must own information security risk. Not delegate it entirely to IT.
• Risk assessment is foundational: Identify your information assets, assess the risks, and implement controls based on those risks.
• Detection and response are critical: You must be able to detect breaches quickly and respond to them in a structured way.
• Technology controls are necessary but not sufficient: Policies and procedures matter as much as firewalls and encryption.
• Continuous improvement is essential: Treat CPS 234 compliance as an ongoing operational discipline, not a one-time audit exercise.
• External support can accelerate progress: An independent assessment and remediation partner can help you move faster and with more confidence.

If you are an Australian insurer serious about CPS 234 compliance, the time to act is now. Start with an assessment, develop a roadmap, get board buy-in, and build controls systematically. The organisations that treat security as a competitive advantage, not a compliance burden, will be the ones that survive and thrive in an increasingly regulated and threat-filled environment.
