ISO/IEC 21827:2008 specifies the Systems Security Engineering Capability Maturity Model (SSE-CMM) — a process reference model describing the characteristics essential to good security engineering across an entire system's lifecycle: concept, development, operation, maintenance, and decommissioning. Unlike ISO 9001, ISO 27001, or ISO 13485, SSE-CMM is not a certifiable requirements standard. There is no IAF accreditation infrastructure for it. London Cert Ltd provides an honest, independent maturity assessment against the model — not an accredited certificate.
We'd rather lose your business than mislead you. ISO/IEC 21827 (SSE-CMM) is a maturity model, not a "requirements" standard — it describes the practices and process areas that characterise good systems security engineering, and defines capability levels (0 through 5) an organisation's processes can be rated against. It does not have an accreditation scheme built around it the way ISO 9001, ISO 27001, or ISO 13485 do. Any provider offering an "accredited ISO 21827 certificate" is not describing something that genuinely exists in the international accreditation system.
What London Cert offers instead is an honest, rigorous maturity assessment: our assessors evaluate your systems security engineering processes against SSE-CMM's process areas, assign capability level ratings, and deliver a detailed benchmarking report with concrete improvement recommendations. This is a genuinely useful exercise for security engineering process improvement, supplier evaluation, and internal benchmarking — it's just not, and never will be marketed as, an accredited certificate.
💡 If your goal is a credential with the same accreditation weight as ISO 9001 or ISO 27001, those are the standards to pursue — SSE-CMM assessment is a complementary process-maturity exercise, most valuable alongside a certified ISMS, not instead of one.
SSE-CMM covers the entire security engineering lifecycle — not just a point-in-time control checklist. It examines how your organisation identifies security risk, specifies and designs security-relevant requirements, verifies and validates security solutions, and coordinates security engineering with other disciplines like systems, software, and hardware engineering, human factors, and testing. It also covers organisational and project-level practices: how security engineering interacts with acquisition, certification, accreditation, and evaluation processes across the supply chain.
Critical: Only certificates issued by IAF-accredited bodies are genuinely valid for GeM, CPPP, and international procurement. India has thousands of fraudulent ISO bodies selling unaccredited certificates that are regularly rejected by compliance teams. London Cert is IAF-accredited — every ISO 21827:2008 certificate we issue is verifiable at verify.londoncert.co.uk.
SSE-CMM's relevance to India has grown sharply in 2026. CERT-In and the Space Industry Association of India (SIA-India) jointly released Space Cyber Security Guidelines 2026 at the DefSat Conference & Expo in New Delhi in February 2026 — explicitly calling for "secure-by-design" architecture across India's satellite, ground station, and supply-chain ecosystem, and framing defence in "depth, breadth, and height." This is precisely the lifecycle-wide, discipline-integrated security engineering maturity SSE-CMM was designed to assess.
The broader context makes this more than an abstract concern: SIA-India's Director General noted that during Operation Sindoor, India recorded over 1.5 million cyberattack attempts, with attacks on government networks surging nearly sevenfold. Separately, India's Security Manual for Licensed Defence Industries mandates strict operational controls, and CERT-In's audit policy for defence-linked entities now includes six-hour incident reporting windows and extended log retention requirements. For defence manufacturers, aerospace suppliers, and space-sector organisations, demonstrating genuine security engineering process maturity — not just point-in-time controls — is increasingly a real differentiator with prospective government and prime-contractor clients.
⚠️ Be cautious of any provider claiming to offer an "IAF-accredited ISO 21827 certificate." No such accreditation scheme exists. A genuine SSE-CMM assessment is a maturity benchmarking exercise with a detailed report — treat any claim beyond that with real skepticism.

Why we don't publish exact prices: ISO 21827:2008 Certification certification cost depends on your specific company size, number of locations, number of employees, industry, and documentation complexity. A fixed published price would either overcharge small businesses or undercharge complex ones. Contact us for a personalised, binding quote within 24 hours — specific to your business.
More employees = more audit time. Audit duration is directly tied to your employee count and the scope of operations being certified.
Each additional location may require separate or extended audit time. Multi-site certifications are priced accordingly — contact us to discuss.
Simple service businesses have fewer process documents than complex manufacturing operations. Documentation scope directly affects cost.
If you already have some quality management processes documented, less preparation work is needed — which can reduce the overall cost.
Remote audits are available for all businesses and are typically more cost-effective. On-site audits are available for clients who need or prefer physical presence.
Most certification companies require you to hire a separate consultant to prepare documentation — and then pay the certification company for the audit on top. London Cert does both. This integrated approach saves time and significantly reduces total cost.
