Cyberis Reply becomes an Assured Service Provider under the NCSC Cyber Adversary Simulation (CyAS) scheme

Cyberis Reply has become an Assured Service Provider under NCSC's CyAS Scheme, strengthening its existing portfolio of accredited adversary simulation capabilities.

Launched by NCSC on 11 November 2026, the CyAS scheme sets robust standards for Assured Service Providers, covering company requirements, the methodology providers must follow and reporting requirements.

Cyber adversary simulation is a form of security testing designed to assess an organisation’s resilience against a realistic, end-to-end cyber attack. Generally used by mature organisations running critical services, it assesses both resistance to an adversary and the organisation’s ability to detect and respond appropriately to a compromise in progress.

Gemma Moore, Partner at Cyberis Reply, said: “We are thrilled to have become an Assured Service Provider  under the NCSC CyAS scheme. Adversary simulation exercises are a powerful tool in the cyber assurance arsenal. They enable us to uncover organisation-wide weaknesses and blind spots, focus investment in controls, and provide incontrovertible evidence to support improvements in business practices. Meeting the scheme’s standards required us to demonstrate advanced capability in adversary simulation. We look forward to helping our clients in the public sector and across the wider CNI ecosystem strengthen their overall cyber security resilience.”

Cyberis Reply’s membership of the CyAS scheme complements its existing cyber adversary simulation capabilities, including CREST-TLPT, CBEST, STAR, STAR-FS, GBEST and GCASE schemes.
