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:

    1. Application & Scoping – Definition of services, locations, and assets within scope

    2. Document & Evidence Review – Assessment of policies, procedures, and control design

    3. Assessment – Review of facilities, processes, and operational practices

    4. Technical Validation – Verification of sanitisation methods and their effectiveness

    5. 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

  • SecurLab combines deep expertise in cybersecurity assurance, ISO-aligned auditing, and NCSC frameworks to deliver rigorous, consistent, and commercially relevant certification services.

    Our approach ensures not only compliance, but demonstrable security assurance that stands up to real-world scrutiny.

    The NCSC CRTF Sanitisation Standard represents the next generation of data destruction assurance.

    Securlab’s certification service enables providers to transition from legacy CAS-S accreditation to a more robust, outcome-focused model ensuring trust, security, and confidence in the handling of sensitive data at end-of-life
