Sanitisation (CAS-S Replacement)
SecurLab provides independent certification against the NCSC Cyber Resilience Test Facility (CRTF) Sanitisation Standard, delivering a robust, government-aligned assurance service for organisations responsible for secure data destruction and media sanitisation. This service is designed as a modern, principles-based replacement for the legacy CAS-S scheme, aligning with the National Cyber Security Centre’s (NCSC) evolving assurance model.
-
The CRTF Sanitisation Standard ensures that service providers can demonstrably and consistently sanitise or destroy data-bearing assets in a manner that mitigates the risk of data compromise. The certification provides customers, regulators, and partners with confidence that sanitisation activities meet stringent, independently verified security outcomes.
-
Scope of Certification
The service applies to organisations delivering:
Physical destruction of data-bearing assets (e.g. shredding, crushing, degaussing)
Logical sanitisation (e.g. secure wiping, cryptographic erasure)
End-to-end handling of media, including collection, transport, processing, and disposal
Supporting processes such as chain of custody, personnel security, and facility controls
-
SecurLab adopts a Principles-Based Sssurance (PBA) methodology aligned with NCSC guidance.
Rather than checklist compliance, the assessment evaluates whether the organisation’s controls effectively achieve defined security outcomes.
The certification process includes:
Application & Scoping – Definition of services, locations, and assets within scope
Document & Evidence Review – Assessment of policies, procedures, and control design
Assessment – Review of facilities, processes, and operational practices
Technical Validation – Verification of sanitisation methods and their effectiveness
Reporting & Certification Decision – Independent determination and issuance of certification
-
The evaluation is structured around key assurance principles, including:
Secure handling and tracking of data-bearing assets
Effectiveness and appropriateness of sanitisation techniques
Integrity of the chain of custody
Personnel trustworthiness and operational discipline
Physical and environmental security of facilities
Transparency and accuracy of customer reporting
-
Certified organisations receive:
Formal CRTF Sanitisation Certification
A detailed assessment report outlining findings and assurance outcomes
Authorisation to be listed as a certified provider under the NCSC CRTF scheme (subject to NCSC processes)
-
Replaces legacy CAS-S certification with a modern, NCSC-aligned standard
Enhances market credibility and trust with government and enterprise customers
Demonstrates independently validated security outcomes
Supports compliance with regulatory and contractual data protection requirements
Differentiates providers in a competitive sanitisation and disposal market
-
