What Does an NCSC Certified CRTF do?
A Cyber Resilience Testing Facility (CRTF) is an NCSC approved body that independently assesses cyber security products and services
Product Assurance Assessment
Verify security claims - Independently validate security claims against NCSC principles, no self‑attestation.
Assess real world claims - Confirm controls are effective in practice, not just in design or documentation.
Support assurance pathways - Outcome focused assurance aligned to modern, evolving systems, not checklists.
Enable trusted procurement - Enable structured progression from readiness to independent and ongoing assurance.
Sanitisation Assurance Assessment
The successor to CAS-S — independently assessed by a certified CRTF.
If your clients expected CAS-S certification, or you held it, SecurLab provides the NCSC-aligned replacement. We independently validate that your disposal processes destroy data irrecoverably — not just remove it.
Former CAS-S replacement — continuity of assurance for ITAD providers and their clients
Independent validation buyers trust — no supplier self-attestation
Data irrecoverability confirmed — not just removal
Audit and procurement ready — structured, traceable evidence
Why NCSC Assurance Matters?
Independent Validation of Security Outcomes
CRTF-aligned assurance replaces self-attestation with independent validation. Evidence that your controls actually work in practice assessed by a certified third party against NCSC principles. Your buyers don't have to take your word for it.
Clear Competitive Advantage in Procurement
CRTF assurance makes you easier to buy from. Independent validation reduces the due diligence burden on procurement teams, shortens sales cycles, and sets you apart from competitors whose security claims rest on documentation alone.
Alignment with NCSC and Government Expectations
CRTF and PBA reflect how the UK government expects cyber risk to be managed across public sector and critical supply chains. Aligning to NCSC principles demonstrates conformance with national best practice and removes friction when selling into regulated environments.
