Siege Cyber provides end-to-end ISO 27001 certification consulting for Australian companies. We work alongside your team to build an Information Security Management System (ISMS) that satisfies the standard, passes audit, and actually improves your security posture. Then we help you maintain it, so your certification remains valid and useful year after year.

Here is what you get:

• A scoped ISMS tailored to your business – We define what is in scope, identify your assets and risks, and design controls that make sense for your size and industry. No cookie-cutter nonsense.
• Policies, procedures, and documentation that pass audit – We provide templates where appropriate, but more importantly, we help you write the policies that reflect how your business actually operates. Auditors spot box-ticking from a mile away.
• Risk assessment and treatment plan – ISO 27001 is a risk-based standard. We help you identify, assess, and document how you are treating information security risks in a way that satisfies the standard and your business needs.
• Gap analysis and remediation roadmap – We assess your current security controls against ISO 27001 Annex A, identify what is missing or insufficient, and give you a clear plan to close the gaps before audit.
• Audit readiness and support – We prepare you for Stage 1 and Stage 2 certification audits, review your evidence, conduct internal audits, and sit alongside you during the formal audit if needed.
• Ongoing maintenance and surveillance audit support – Certification is not a one-off. We provide ongoing support to keep your ISMS current and help you through annual surveillance audits and recertification every three years.

Our Process

We have guided dozens of Australian companies through ISO 27001 certification. Here is how we do it.

1. Scoping and Gap Analysis (Weeks 1-2)

We meet with your team to define the scope of your ISMS, understand your business and technology environment, and conduct a gap analysis against ISO 27001:2022 requirements. You will leave this phase with a clear picture of what needs to be done, how long it will take, and what it will cost.

2. Risk Assessment and Control Selection (Weeks 3-4)

We facilitate a structured risk assessment to identify your information security risks, then help you select the appropriate controls from Annex A to treat those risks. This is where we tailor the ISMS to your business rather than applying every control blindly.

3. Documentation and Implementation (Weeks 5-12)

This is the heavy lifting. We work with you to develop your ISMS documentation (policies, procedures, risk treatment plan, statement of applicability), implement the required controls, and establish the processes you need to demonstrate compliance. Depending on your starting point, this phase typically takes 2-3 months.

4. Internal Audit and Management Review (Weeks 13-14)

Before the certification audit, we conduct an internal audit of your ISMS to ensure everything is in place and your evidence is audit-ready. We also facilitate a management review so your leadership team can formally approve the ISMS and demonstrate top-level commitment.

5. Certification Audit Support (Weeks 15-18)

We prepare you for the two-stage certification audit, review your evidence packs, brief your team on what to expect, and provide support during the audit itself. Stage 1 focuses on documentation review. Stage 2 involves interviews and evidence checks. We make sure you are ready for both.

6. Ongoing Maintenance and Surveillance (Year 1 Onwards)

Once you are certified, we help you maintain your ISMS and prepare for annual surveillance audits. This includes updating documentation, managing changes, monitoring compliance, and ensuring your ISMS remains effective as your business evolves.

Who This Is For

This service is built for Australian SaaS companies, technology businesses, and SMBs who need ISO 27001 certification to win enterprise customers, satisfy investor or board requirements, or meet regulatory expectations.

You are a good fit if:

• You are selling to enterprise or government clients who require ISO 27001 as part of their vendor assessment
• You have been asked for ISO 27001 in an RFP or security questionnaire and need to get certified quickly
• Your board, investors, or customers are asking for independent verification of your information security programme
• You have already purchased Vanta or Drata and need expert help to navigate the gaps, make the right decisions, and actually achieve certification
• You are a growing business and want to build security governance that scales with you
• You need someone who understands the Australian regulatory context (Privacy Act 1988, APRA CPS 234, Essential Eight) and can connect the dots

Siege Cyber is an official partner of both Vanta and Drata. If you have already invested in one of these platforms, we can work within your existing tool to provide the expert guidance, policy development, risk assessment, and audit readiness support that the platform alone cannot deliver. We bridge the gap between automation and the human judgement still required to achieve certification.

Why Choose Siege Cyber

20+ years of hands-on experience. Our Technical Director, Peter Stewart, has spent over two decades in the cybersecurity industry in both technical and leadership roles. We understand information security from the ground up and can speak your language, whether you are an engineer or a business owner.

Official Vanta and Drata partner. We are one of a small number of Australian consultancies officially recognised by the two leading compliance automation platforms. If you have already purchased either tool, we know exactly how to use it effectively and where the platform needs to be supplemented with expert input.

Australian expertise that matters. We understand the local regulatory environment, including the Privacy Act 1988, APRA CPS 234, and the ASD Essential Eight. We help you align ISO 27001 with the broader compliance obligations that apply to Australian businesses, so you are not building security in a vacuum.

No templates-and-disappear consulting. We work alongside your team from start to finish. You get direct access to experienced consultants who understand your business and are invested in your success, not a junior associate working from a checklist.

Practical, not theatrical. We care about real security outcomes, not compliance theatre. The ISMS we help you build will pass audit, but it will also improve how you manage information security day-to-day. That is the whole point.

Frequently Asked Questions

How long does ISO 27001 certification take?

For most Australian SaaS and SMB companies, the full process from kickoff to certification takes between 4 and 6 months. The timeline depends on the size and complexity of your business, the maturity of your existing security controls, and how quickly your team can implement the required changes. We provide a detailed project plan during the scoping phase so you know exactly what to expect.

Do we need to implement all 93 Annex A controls?

No. ISO 27001 is a risk-based standard. You are required to assess all 93 controls in Annex A and determine which ones are applicable to your risks. Some controls will be necessary, others will not be relevant to your business, and you can document your reasoning in the Statement of Applicability. We help you make these decisions based on your actual risk profile, not a checkbox mentality.

What happens if we fail the certification audit?

If the auditor raises non‑conformities during the Stage 2 audit, you’ll have a chance to fix them before certification is granted. Minor issues can usually be cleared with extra evidence or documentation. Major issues may need remediation and a follow‑up audit, but Siege Cyber helps you resolve them quickly.

We don’t just prepare you to avoid failure, we stay with you to fix any gaps, update controls, and resubmit evidence. In our experience, clients who follow our process and work with us typically pass certification on the first attempt.

Can you help if we have already started the process internally?

Absolutely. Many companies begin the ISO 27001 journey on their own, realise it is more complex than expected, and bring us in to get things back on track. We can review what you have already done, identify gaps, and take over from wherever you are in the process. No need to start from scratch.

Do we need ISO 27001 if we already have SOC 2 or are working towards it?

ISO 27001 and SOC 2 are complementary but different. SOC 2 is more common in the SaaS market, while ISO 27001 is recognised globally and often required by European and Australian enterprise customers. If you are selling internationally or to large enterprises, you may need both. The good news is that much of the work overlaps, and we can help you align the two frameworks to avoid duplication.

What is involved in maintaining ISO 27001 after certification?

ISO 27001 is not a once-and-done certification. Once certified, you will need to undergo annual surveillance audits to demonstrate ongoing compliance, and a full recertification audit every three years. You also need to keep your ISMS documentation current, conduct regular internal audits and management reviews, and update your risk assessments as your business changes. We provide ongoing support to make this manageable without requiring a full-time compliance resource.

How much does ISO 27001 certification cost?

The cost depends on the size and complexity of your organisation, the scope of your ISMS, the maturity of your existing controls, and the level of support you need. We provide a detailed quote after the initial scoping consultation so there are no surprises. Contact us for a free consultation and we will give you a realistic picture of the investment involved.
