Need help with ISO 27001? ProtectifyAI supports readiness assessments, ISMS implementation and preparation for independent certification. We work with UK and European organisations to define a useful scope, assess security risks and put controls into everyday operation.

You can engage us for a gap assessment, a full implementation or targeted remediation before an audit. The deliverables and responsibilities are agreed upfront, including what your internal owners must approve and operate.

🔎

Assess current gaps

An independent gap assessment against ISO/IEC 27001:2022, scoped to your actual systems — not a generic checklist.

🛠️

Implement and operate the ISMS

We help build and embed the ISMS with your team, so your people can run it day to day, not just pass an audit once.

🧭

Independently review readiness

A readiness review ahead of Stage 1 or Stage 2, with findings reported honestly — including where we are not the right people to also sign off, if we built the controls being reviewed.

Where we have also implemented the controls being assessed, we will say so plainly rather than presenting a readiness review as fully independent; a genuinely independent internal audit function or third party should perform that specific check before certification.

Further reading for your implementation plan

Start with the ISO 27001 startup guide hub for the overall certification route. Then use the ISO 27001 for startups guide to set a proportionate scope, the readiness assessment guide to evaluate your starting point, and the implementation timeline to plan owners and audit dependencies.

What is ISO 27001 implementation?

ISO 27001 implementation means designing, building, and embedding an Information Security Management System (ISMS) that meets the requirements of ISO/IEC 27001:2022. It covers policy creation, risk assessment, Annex A control selection and deployment, internal audit, management review, and preparation for Stage 1 and Stage 2 certification audits conducted by an accredited, independent certification body. ISO 27001 concerns the ISMS specifically — it is not a blanket guarantee that every product is free of security issues. See ISO's overview of the standard.

The problem most organisations face with ISO 27001

ISO 27001 has 93 controls across 4 themes in Annex A. The standard requires a documented Statement of Applicability explaining which controls you implement and why. It requires a formal risk assessment methodology, a risk register, and evidence that management reviews the ISMS at defined intervals.

None of this is intuitive if you have not done it before. Many teams download a policy template pack, rename the company name, and discover months later that their auditor considers it inadequate — because the policies were not tailored to their actual systems, and there is no evidence the controls are actually operating.

ProtectifyAI works with your team to implement the ISMS, not just hand over documents. We help wire controls into your existing tooling, build processes your team can actually run, and support you through both audit stages.

What we implement

Frequently asked questions

Timelines vary with organisation size, existing controls and team availability. We provide a scoped estimate after an initial assessment rather than a universal figure — and Stage 1/Stage 2 audit scheduling with your certification body is a separate variable from implementation time.

Stage 1 is a documentation review — the auditor confirms your ISMS is designed correctly and your policies are in place. Stage 2 is the main certification audit, where the auditor tests whether controls are actually operating as documented. You must pass Stage 1 before Stage 2 can proceed. Nonconformities from Stage 1 must be closed before Stage 2 begins.

We agree a clear scope, deliverables and fee upfront once we understand your organisation's size and starting point. Certification body fees are separate, vary by provider and scope, and are quoted independently — we do not control or benefit from the certification body's fee.

An ISMS is a documented framework of policies, processes, and controls for managing information security risk. ISO 27001 requires one. For a startup, an ISMS does not need to be complex — a well-designed lean ISMS for a 10–50 person company can be operated by the existing team without a dedicated security hire.

ISO 27001 is an internationally recognised certification (pass/fail) governed by ISO/IEC. SOC 2 is a US attestation standard governed by the AICPA. ISO 27001 is dominant in UK and European procurement; SOC 2 is dominant in US enterprise procurement. Both are worth pursuing for AI startups targeting global enterprise deals — the control overlap is ~70%, making the second certification much faster.

No. A compliance platform helps automate evidence collection but is not required for ISO 27001 certification. ProtectifyAI is entirely vendor-neutral. We will recommend whether a platform makes financial and operational sense for your team, and work with whichever you choose — or build a manual evidence process if that is the better fit.
