The Core Decision

You’re running an Australian software company. A major enterprise customer in Singapore wants ISO 27001. Your largest US customer wants SOC 2. A European prospect won’t buy without ISO 27001. Your board is asking: which do we do first?

This is not a theoretical question. We’ve helped 50+ Australian companies ship AI products and modernise operations, and we’ve seen this decision cost founders 6–12 months of stalled revenue and millions in lost pipeline.

The honest answer: it depends on where your revenue is, how fast you need to close deals, and whether you can afford to run both tracks in parallel.

But the strategic answer is sharper. Most Australian B2B SaaS and platform companies should pursue ISO 27001 first—because it’s internationally recognised, opens doors in APAC and Europe, and provides a stronger foundation for SOC 2 later. However, if your sales pipeline is US-heavy, SOC 2 often moves faster and costs less upfront.

The best companies—the ones closing $10M+ ARR deals across regions—run both in parallel. It takes discipline, but it works.

What ISO 27001 Actually Is

ISO 27001 is an international standard for information security management systems (ISMS). It’s published by the International Organization for Standardization and adopted in 190+ countries. When you achieve ISO 27001 certification, you’re saying: “We have a documented, audited, independently verified system for managing information security across our entire organisation.”

ISO 27001 is not a checklist. It’s a framework. It requires you to:

  • Identify all information assets and risks
  • Design and implement controls to mitigate those risks
  • Document your security policies, procedures, and evidence
  • Run an internal audit
  • Submit to an external audit by an accredited certification body
  • Maintain the system through annual surveillance audits

The standard is built on 114 controls grouped into 14 domains: information security policies, organisation of information security, human resource security, asset management, access control, cryptography, physical and environmental security, operations security, communications security, system acquisition/development/maintenance, supplier relationships, information security incident management, business continuity management, and compliance.

When an auditor certifies you, they’re confirming that your ISMS covers these domains, that controls are in place and working, and that you can sustain them. The certification is valid for three years, with annual surveillance audits required to maintain it.

For Australian companies, ISO 27001 is the gold standard. It’s recognised by regulators, enterprise procurement teams, and government agencies across APAC and Europe. If you’re selling to banks, insurance companies, government, or large enterprises in Australia, Singapore, India, or Europe, ISO 27001 is often non-negotiable.

What SOC 2 Actually Is

SOC 2 is an attestation, not a certification. It’s published by the American Institute of CPAs (AICPA) and is specific to service organisations—companies that store, process, or transmit customer data.

Unlike ISO 27001, SOC 2 doesn’t certify you. Instead, an independent auditor (a licensed CPA firm) evaluates your controls against AICPA Trust Services Criteria and issues a report. That report comes in two flavours:

  • Type I: A point-in-time snapshot of your controls and their design (usually not useful for sales)
  • Type II: A 6–12 month observation period proving controls are operating effectively (what enterprise customers actually want)

SOC 2 Type II focuses on five Trust Services Criteria:

  1. Security: Protecting against unauthorised access
  2. Availability: Systems are available for operation and use
  3. Processing Integrity: Transactions are complete, accurate, timely, and authorised
  4. Confidentiality: Information designated as confidential is protected
  5. Privacy: Personal information is collected, used, retained, disclosed, and disposed of to meet privacy objectives

Most companies pursue Security, Availability, and Processing Integrity. Confidentiality and Privacy are less common.

SOC 2 Type II takes 6–12 months because the auditor needs to observe your controls in operation. Once you have it, the report is valid for one year, and you’ll need annual audits to maintain it.

SOC 2 is primarily a US standard. It’s the de facto requirement for SaaS companies selling to US enterprises, mid-market firms, and venture-backed startups. Outside the US, recognition drops sharply. A Japanese bank won’t ask for SOC 2. A German enterprise might not recognise it. But a US Fortune 500 company or a well-funded US startup will almost certainly require it.

The Australian Context: Geography Matters

Australia is in the APAC region, but our economy is genuinely split between three zones: domestic, US-facing, and international (Europe, APAC, government).

Domestic Australian buyers (ASX companies, major banks, government agencies, large enterprises) typically require ISO 27001. They’re aligned with international standards, and ISO 27001 is the lingua franca of enterprise procurement in Australia. If you’re selling to Westpac, NAB, the ATO, or the NDIA, you need ISO 27001.

US-facing Australian companies (SaaS, data analytics, AI platforms, fintech) often face SOC 2 requirements from their largest customers. If your Series A or Series B is US-funded, your investors expect SOC 2 on the roadmap. If you’re selling to US mid-market or enterprise customers, SOC 2 is the price of entry.

International and APAC buyers (Singapore, India, Japan, Europe) almost universally prefer ISO 27001. The European Union’s regulations (GDPR, NIS2) are built on ISO 27001 principles. Singapore’s financial regulators reference ISO 27001. India’s data protection frameworks align with ISO 27001.

For most Australian B2B SaaS companies, the revenue split looks like: 30–40% domestic, 40–50% US, 10–20% international. That split should inform your compliance strategy.

We’ve worked with PADISO’s case studies across this landscape, and the pattern is consistent: companies that pursue ISO 27001 first unlock domestic and international revenue, then layer SOC 2 to capture US deals. Companies that pursue SOC 2 first often find themselves re-working controls to meet ISO 27001 later—it’s slower and more expensive.

Timeline and Cost Comparison

Let’s talk real numbers. These are based on our experience working with 50+ Australian companies through audit-readiness and compliance programs.

ISO 27001 Timeline

4–6 months for a well-run implementation (seed-to-Series A company, <50 staff, single product).

  • Weeks 1–2: Gap analysis, scope definition, risk assessment
  • Weeks 3–6: Policy and procedure development, control design
  • Weeks 7–12: Control implementation, evidence gathering, internal audit
  • Weeks 13–16: External audit, certification
  • Weeks 17–24: Remediation (if needed), final certification

Larger companies (100+ staff, multiple products, complex infrastructure) typically take 6–9 months.

Cost: AUD $40,000–$120,000 for a small-to-mid company. This includes:

  • External audit fees: AUD $15,000–$40,000
  • Consultancy support: AUD $20,000–$60,000 (if you need external help)
  • Internal time: 2–3 FTE months

If you’re using PADISO’s security audit service, we provide gap analysis, remediation planning, and end-to-end certification support via Vanta, which can compress this timeline and reduce your internal burden.

SOC 2 Type II Timeline

6–12 months minimum (the auditor must observe controls for at least 6 months, often 12).

  • Months 1–2: Scoping, control design, documentation
  • Months 2–7 (or 2–12): Observation period (auditor is watching)
  • Months 7–8 (or 12–13): Audit completion, report issuance

The observation period is non-negotiable. You cannot skip it. Many Australian companies underestimate this; they think they can do SOC 2 in 3–4 months. You can’t.

Cost: AUD $50,000–$150,000 for a small-to-mid company. This includes:

  • Audit fees: AUD $25,000–$80,000
  • Consultancy support: AUD $20,000–$60,000 (if you need external help)
  • Internal time: 1–2 FTE months (less than ISO 27001, because the scope is narrower)

SOC 2 is often cheaper than ISO 27001 upfront, but the observation period means you can’t compress the timeline.

The Parallel Play

If you run both simultaneously, you don’t double the cost. Here’s why:

  • Shared documentation: Risk assessments, policies, and procedures overlap 60–70%.
  • Shared controls: 80%+ of ISO 27001 controls map to SOC 2 Trust Services Criteria.
  • Shared evidence: Logs, audit trails, access reviews, vulnerability scans count for both.

Running both in parallel typically costs AUD $70,000–$180,000 (not AUD $140,000–$360,000). You’re building the security system once, not twice.

Timeline for parallel: 6–9 months. ISO 27001 certification takes 4–6 months; SOC 2 Type II takes 6–12 months. If you start both at week 1, you’ll have ISO 27001 certified by month 6 and SOC 2 Type II by month 9–12.

For a company closing $5M+ ARR deals across US and international markets, this is the fastest path to capturing both buyer segments.

Buyer Demand: Where Your Revenue Comes From

This is the decision that matters. Compliance is not an end in itself; it’s a revenue gate. You pursue it because your customers require it.

ISO 27001 Demand

Who requires it:

  • Australian government agencies (all procurement)
  • ASX-listed companies (most require it)
  • Major Australian banks and financial services (non-negotiable)
  • Large enterprises in APAC (Singapore, India, Japan)
  • European enterprises (especially regulated industries: finance, healthcare, telco)
  • Australian insurance companies, superannuation funds, healthcare providers

Deal size: Often large. Government contracts start at AUD $500K+. Enterprise deals in finance and insurance often exceed AUD $1M+ ARR.

Sales cycle: Long (6–12 months), but compliance is one gate among many. If you have ISO 27001, you clear a major gate.

Prevalence: In APAC and Europe, ISO 27001 is the default ask. If you’re selling to 100 enterprise prospects in these regions, 70–80 will require it.

SOC 2 Demand

Who requires it:

  • US mid-market and enterprise SaaS customers (very common)
  • US-funded startups and scale-ups (standard requirement)
  • US financial services and fintech (common, though not universal)
  • Some large US tech companies (Google Cloud, AWS partnerships often require it)
  • US healthcare and life sciences (increasingly common)

Deal size: Highly variable. Mid-market deals might be AUD $100K–$500K ARR. Enterprise deals can exceed AUD $5M+ ARR.

Sales cycle: Medium (3–6 months). SOC 2 is a gate, but US buyers are more flexible on timing than international buyers.

Prevalence: In the US, SOC 2 Type II is the de facto standard for B2B SaaS. If you’re selling to 100 US prospects, 60–70 will require it.

The Geographic Split

Here’s where strategy enters. If your revenue breakdown is:

  • 60%+ US: Prioritise SOC 2 Type II. It’s faster to market, cheaper upfront, and directly opens US revenue. ISO 27001 can follow in 12 months.
  • 40%+ APAC/Europe: Prioritise ISO 27001. It opens larger geographies and is the prerequisite for European and APAC enterprise deals.
  • Balanced (40% US, 40% APAC/Europe, 20% domestic): Run both in parallel. The cost premium is 20–30%, but you unlock all three markets simultaneously.

We’ve seen this play out repeatedly. A Sydney fintech with 70% US revenue pursued SOC 2 first, got certified in 9 months, and closed $2M+ in US deals. They then pursued ISO 27001 and opened AUD $1.5M+ in APAC and domestic enterprise revenue within 6 months. Total time: 15 months. Total revenue unlocked: AUD $3.5M+.

A Sydney data analytics company with balanced revenue pursued ISO 27001 first, certified in 5 months, opened AUD $2M+ in APAC and domestic revenue, then pursued SOC 2 Type II in parallel. They had both certifications by month 10 and closed AUD $1.2M+ in US deals by month 12. Total revenue unlocked: AUD $3.2M+.

The parallel play was faster in the second case because ISO 27001 opened revenue earlier, and the parallel SOC 2 effort didn’t delay ISO 27001 completion.

Running Both in Parallel: The Strategic Play

If you decide to run both, you need a clear operating model. Half-measures fail.

Why Parallel Works

  1. Control overlap: 80%+ of ISO 27001 controls directly map to SOC 2 Trust Services Criteria. You’re not building two separate security systems; you’re building one system that satisfies both frameworks.

  2. Documentation efficiency: Risk assessments, policies, procedures, and evidence gathering happen once. You tag evidence for both frameworks, but you don’t duplicate the work.

  3. Timeline efficiency: ISO 27001 takes 4–6 months to certification. SOC 2 Type II takes 6–12 months (due to the observation period). If you start both at week 1, ISO 27001 is done by month 6, and SOC 2 is done by month 9–12. You don’t wait for ISO 27001 to finish before starting SOC 2.

  4. Cost efficiency: Running both costs 20–30% more than running one, not 100% more. Shared audit, shared documentation, shared evidence.

The Execution Model

Phase 1 (Weeks 1–4): Scoping and Planning

  • Define scope for both frameworks (usually identical or overlapping)
  • Conduct joint risk assessment
  • Map controls: ISO 27001 controls → SOC 2 Trust Services Criteria
  • Create a single control matrix with evidence requirements for both
  • Assign ownership: who’s responsible for each control?

Phase 2 (Weeks 5–12): Design and Implementation

  • Develop policies, procedures, and standards (single set, tagged for both frameworks)
  • Implement controls (access management, encryption, logging, incident response, etc.)
  • Gather evidence (screenshots, logs, audit trails, training records)
  • Run internal audit (test controls against both frameworks)

Phase 3 (Weeks 13–16): ISO 27001 External Audit

  • External auditor reviews documentation and evidence
  • Auditor tests controls
  • Remediation (if needed)
  • Certification issued

Phase 4 (Weeks 13–26, or longer): SOC 2 Type II Observation

  • SOC 2 auditor begins observation period
  • You continue operating, maintaining controls, gathering evidence
  • Auditor observes controls in operation for 6–12 months
  • At month 6–12, auditor completes testing and issues report

Tools and Platforms

To run both in parallel, you need visibility into your control environment. Most Australian companies we work with use:

  • Vanta: Automated evidence collection, control mapping, audit-readiness. Vanta maps controls to both ISO 27001 and SOC 2, which is invaluable for parallel runs. PADISO’s security audit service is powered by Vanta, providing gap analysis, remediation, and end-to-end certification support.
  • Drata: Similar to Vanta; good for smaller companies.
  • AuditBoard: Audit workflow and evidence management.
  • Spreadsheets: Many companies still use them. It’s slower, but it works if you’re disciplined.

For parallel runs, Vanta is the best choice because it automates evidence collection and explicitly maps controls to both frameworks. It saves 200–300 hours of manual work.

Implementation Roadmap for Australian Enterprises

Let’s build a concrete roadmap based on your situation.

Scenario 1: US-Heavy Revenue (60%+ US)

Decision: Pursue SOC 2 Type II first, then ISO 27001.

Roadmap:

  1. Months 1–2: SOC 2 scoping, control design, documentation
  2. Months 2–8: SOC 2 observation period (auditor is watching)
  3. Month 8–9: SOC 2 audit completion, report issuance
  4. Months 7–10 (parallel): ISO 27001 gap analysis, policy development, control implementation
  5. Months 10–12: ISO 27001 external audit, certification

Timeline: 12 months for both. Cost: AUD $90,000–$200,000. Revenue impact: SOC 2 by month 9 unlocks US deals. ISO 27001 by month 12 unlocks APAC and international deals.

Scenario 2: APAC/Europe-Heavy Revenue (60%+ international)

Decision: Pursue ISO 27001 first, then SOC 2 Type II.

Roadmap:

  1. Months 1–2: Gap analysis, risk assessment, control design
  2. Months 3–5: Policy development, control implementation, evidence gathering
  3. Months 5–6: Internal audit, external audit, certification
  4. Months 4–12 (parallel): SOC 2 scoping, control design, observation period
  5. Months 12–13: SOC 2 audit completion, report issuance

Timeline: 13 months for both. Cost: AUD $85,000–$190,000. Revenue impact: ISO 27001 by month 6 unlocks APAC and international deals. SOC 2 by month 12–13 unlocks US deals.

Scenario 3: Balanced Revenue (40% US, 40% APAC, 20% domestic)

Decision: Run both in parallel.

Roadmap:

  1. Weeks 1–4: Joint scoping, control mapping, planning
  2. Weeks 5–12: Policy development, control implementation, evidence gathering
  3. Weeks 13–16: ISO 27001 external audit, certification
  4. Weeks 13–26+: SOC 2 Type II observation period, audit, report issuance

Timeline: 6 months for ISO 27001, 6–9 months for SOC 2 Type II (total 6–9 months for both). Cost: AUD $80,000–$180,000. Revenue impact: ISO 27001 by month 6 unlocks APAC and international deals. SOC 2 by month 9 unlocks US deals.

Common Mistakes We See

After working with dozens of Australian companies, we’ve seen patterns of failure. Here’s how to avoid them.

Mistake 1: Underestimating the SOC 2 Observation Period

Companies think: “We can do SOC 2 in 3 months.”

Reality: The auditor must observe controls for 6–12 months. You cannot compress this. The observation period is a regulatory requirement, not a suggestion.

Fix: If you need SOC 2 by month 6, start in month 1. If you need it by month 9, start in month 3. Plan backwards from your revenue deadline.

Mistake 2: Treating Compliance as a One-Time Project

Companies think: “We’ll get certified, and we’re done.”

Reality: ISO 27001 requires annual surveillance audits. SOC 2 Type II requires annual audits. You’re building an ongoing compliance program, not a project.

Fix: Budget for annual audits (AUD $15,000–$30,000 per year for ISO 27001, AUD $20,000–$40,000 for SOC 2 Type II). Assign a compliance owner. Build compliance into your operational rhythm.

Mistake 3: Scoping Too Broadly

Companies think: “We’ll scope everything—all offices, all products, all systems.”

Reality: Broad scoping makes audits harder and more expensive. Narrow your scope to your core product and critical systems.

Fix: Scope your SaaS product and the systems that support it. Exclude non-critical systems, legacy applications, and non-customer-facing operations. You can expand scope later.

Mistake 4: Hiring an Auditor Before Defining Your Control Environment

Companies think: “Let’s hire an auditor to tell us what we need to do.”

Reality: Auditors audit; they don’t design. If you hire an auditor before you’ve built controls, you’ll spend 2–3 months designing with the auditor, which is expensive (auditor time costs AUD $200–$400/hour).

Fix: Do a gap analysis first. Understand what controls you have and what you’re missing. Then hire an auditor to verify your design and execute the audit.

Mistake 5: Neglecting Evidence Collection

Companies think: “We’ll collect evidence during the audit.”

Reality: Auditors need evidence. If you don’t have logs, screenshots, training records, or audit trails, the audit will stall. Evidence collection is ongoing, not a last-minute task.

Fix: Assign someone to collect evidence monthly. Use Vanta or a similar platform to automate it. By the time the auditor arrives, you should have 80%+ of evidence ready.

Mistake 6: Running Parallel Efforts Without a Control Matrix

Companies think: “We’ll do ISO 27001 and SOC 2 separately and figure out the overlap later.”

Reality: Without a control matrix mapping ISO 27001 controls to SOC 2 Trust Services Criteria, you’ll duplicate work, miss controls, and spend 30–50% more time and money.

Fix: Create a single control matrix at the start. Map every ISO 27001 control to SOC 2 criteria (or note where there’s no mapping). Use this matrix to guide design, implementation, and evidence gathering. SOC 2 vs ISO 27001: Which Compliance Framework Should You Choose? provides a detailed comparison to inform your matrix.

Implementation Roadmap for Australian Enterprises

Now let’s get tactical. Here’s a step-by-step roadmap for a typical Australian B2B SaaS company (20–50 staff, single product, AUD $500K–$2M ARR).

Week 1–2: Assess and Decide

  1. Audit your customer pipeline: How many prospects require ISO 27001? How many require SOC 2? What’s the revenue at stake for each?
  2. Map your geography: What % of revenue is US, APAC, domestic?
  3. Assess your current state: What controls do you have? What’s your gap to ISO 27001 and SOC 2?
  4. Decide on sequencing: Based on revenue, pursue one first or both in parallel.

Output: A one-page decision memo: “We’re pursuing [ISO 27001 / SOC 2 / both], because [revenue rationale].”

Week 3–4: Scoping and Planning

  1. Define scope: What systems, data, and people are in scope? (Usually: your SaaS product, cloud infrastructure, employee access, data handling.)
  2. Conduct risk assessment: What are the top 20 risks to confidentiality, integrity, and availability of customer data?
  3. Create a control matrix: Map ISO 27001 controls (if pursuing it) and SOC 2 Trust Services Criteria to your risks.
  4. Assign ownership: Who owns access management? Encryption? Incident response? Audit logging?

Output: A control matrix, risk assessment, and ownership chart.

Week 5–12: Design and Implement

  1. Develop policies and procedures: Access control, change management, incident response, business continuity, vendor management, data classification, etc.
  2. Implement controls: Configure MFA, encryption, logging, vulnerability scanning, regular backups, etc.
  3. Gather evidence: Screenshots of configurations, access logs, training records, vulnerability scan reports, etc.
  4. Run an internal audit: Test controls. Do they work? Is evidence in place?

Output: Policies, implemented controls, evidence, internal audit report.

Week 13–16: External Audit (ISO 27001) or Start Observation (SOC 2)

  1. Hire an external auditor (if not already done).
  2. Submit to audit: Provide documentation, evidence, and access to systems.
  3. Remediate findings: Address any control gaps or evidence gaps.
  4. Receive certification (ISO 27001) or begin observation period (SOC 2).

Output: ISO 27001 certificate or SOC 2 observation period underway.

Month 6–12: Ongoing Compliance

  1. Maintain controls: Continue operating controls, gathering evidence, and running internal audits.
  2. Complete SOC 2 observation (if running in parallel): Auditor observes for 6–12 months.
  3. Plan for annual audits: Budget for surveillance audits (ISO 27001) or annual audits (SOC 2).

Output: SOC 2 Type II report, ongoing compliance program.

The Role of Compliance in Your Growth Strategy

Compliance is not a cost centre; it’s a revenue gate. Every month you delay certification is a month of lost pipeline.

We’ve worked with companies across PADISO’s AI agency services for enterprises and AI advisory services in Sydney and beyond, and the pattern is consistent: companies that achieve ISO 27001 or SOC 2 certification see immediate uptick in enterprise deal closure rates (20–40% improvement in win rates for deals over AUD $500K).

For Australian companies, this is especially true. ISO 27001 vs SOC 2 - Compliance Council notes that ISO 27001 is the default expectation in Australia and APAC, while The difference between SOC 2 and ISO 27001 - Thoropass highlights that SOC 2 is the de facto standard in the US.

Your compliance strategy should align with your revenue strategy. If you’re pursuing US enterprise revenue, SOC 2 is a prerequisite. If you’re pursuing APAC and international revenue, ISO 27001 is non-negotiable. If you’re pursuing both, run them in parallel.

Choosing Your Partner

If you decide to get external support—and most companies do—choose a partner who understands both frameworks and your business.

What to look for:

  1. APAC experience: Have they helped Australian companies through ISO 27001 and SOC 2? Do they understand the Australian regulatory environment?
  2. Technology expertise: Do they understand your tech stack (cloud platforms, databases, security tools)? Can they advise on control implementation, not just documentation?
  3. Outcome focus: Do they talk about timelines and costs upfront? Do they have a track record of getting companies certified on time and on budget?
  4. Vanta integration: If you’re using Vanta for evidence automation, does your partner know how to leverage it?

PADISO’s security audit service is built on this model. We provide gap analysis, remediation planning, and end-to-end certification support via Vanta. We’ve helped 50+ Australian companies achieve SOC 2 and ISO 27001 compliance, and we understand both the technical and business sides of the decision.

Alternatively, if you’re building a broader AI and security modernisation program, PADISO offers AI strategy and readiness services that integrate compliance into your overall technology roadmap. For Sydney startups and SMEs, this integrated approach often accelerates both compliance and product development.

Common Questions

Q: Can we do ISO 27001 and SOC 2 at the same time?

A: Yes. Most companies that do both run them in parallel. It costs 20–30% more than running one, but it’s faster than running them sequentially. The key is a control matrix that maps controls to both frameworks.

Q: How long does ISO 27001 take?

A: 4–6 months for a small-to-mid company (20–50 staff). Larger companies take 6–9 months. The timeline depends on your current control maturity and the complexity of your systems.

Q: How long does SOC 2 Type II take?

A: 6–12 months minimum (due to the observation period). You cannot compress this. Most companies take 9–12 months from start to report issuance.

Q: Which is cheaper?

A: SOC 2 Type II is usually cheaper upfront (AUD $50K–$150K vs AUD $40K–$120K for ISO 27001), but the observation period means you can’t compress the timeline. Running both in parallel costs AUD $70K–$180K, which is 20–30% more than running one.

Q: Do we need both?

A: It depends on your revenue. If 60%+ of your revenue is US, SOC 2 is non-negotiable. If 60%+ is APAC or Europe, ISO 27001 is non-negotiable. If balanced, both are worth pursuing.

Q: What if we can’t afford both?

A: Prioritise based on revenue. If US revenue is larger, pursue SOC 2 first. If APAC/international revenue is larger, pursue ISO 27001 first. You can pursue the second framework 12 months later.

Q: Can we do a partial scope (e.g., just our SaaS product, not our whole company)?

A: Yes. Both ISO 27001 and SOC 2 allow you to scope your audit to specific systems, products, or business units. Narrow scoping makes audits faster and cheaper.

Q: What happens after we’re certified?

A: ISO 27001 requires annual surveillance audits (AUD $15K–$30K/year). SOC 2 Type II requires annual audits (AUD $20K–$40K/year). You maintain your certification by keeping controls operating and evidence current.

Next Steps: Getting Started

If you’re ready to move forward, here’s what to do:

Step 1: Decide on Your Sequencing

Answer these three questions:

  1. What % of your revenue is US? APAC? Domestic?
  2. How many prospects in your pipeline require ISO 27001? SOC 2?
  3. Can you afford to run both in parallel, or do you need to sequence them?

Based on your answers, decide: ISO 27001 first, SOC 2 first, or both in parallel.

Step 2: Run a Gap Analysis

Understand your current control maturity. You can do this internally (1–2 weeks) or with external support (1 week with a partner like PADISO).

Output: A one-page gap assessment showing what controls you have and what you’re missing.

If you want external support, PADISO’s security audit service can help. We provide gap analysis, remediation planning, and end-to-end certification support via Vanta. We’ve helped 50+ Australian companies achieve compliance on time and on budget.

Alternatively, you can hire a Big Four consulting firm (Deloitte, EY, PwC, KPMG), but expect to pay 2–3x more for similar outcomes.

Step 4: Build Your Control Matrix

Create a single document mapping your risks, ISO 27001 controls (if pursuing it), SOC 2 Trust Services Criteria, and evidence requirements. This matrix will guide your design, implementation, and audit.

Step 5: Assign Ownership and Start Implementing

Assign a compliance owner (usually your CTO, VP Eng, or Head of Ops). Start implementing controls, gathering evidence, and building your compliance program.

Step 6: Plan Your Audit

Once you have 80%+ of controls in place and evidence gathered, hire an external auditor and schedule your audit.

Final Thoughts

ISO 27001 vs SOC 2 is not a binary choice for most Australian companies. It’s a sequencing decision based on where your revenue is and how fast you need to move.

If you’re US-heavy, SOC 2 moves faster and opens US enterprise revenue. If you’re APAC-heavy or international, ISO 27001 opens larger geographies and is the prerequisite for European and APAC deals. If you’re balanced, run both in parallel and unlock all three markets simultaneously.

The best companies—the ones closing $10M+ ARR deals across regions—have both certifications and maintain them rigorously. They treat compliance as a revenue gate and a competitive advantage, not a checkbox.

Your compliance strategy should be as deliberate as your product strategy. Decide based on revenue, execute with discipline, and measure impact in deal closure rates and pipeline velocity.
