The ASSURE scheme, launched in January 2020, is the Civil Aviation Authority’s (CAA) third-party cyber security audit model.

Aviation organisations such as UK airports, air carriers and air navigation service providers in scope of the CAA’s Cyber Security Oversight Process are required to complete an ASSURE Cyber Audit. The ASSURE Scheme provides the aviation industry with a mechanism to manage their cyber security risks without compromising aviation safety, security or resilience whilst ensuring compliance with applicable regulations.

Arcanum have been accepted onto the CAA ASSURE short-list of approved audit service providers having demonstrated the competence and skill to be recognised as an ASSURE Cyber Supplier. As an ASSURE Cyber Supplier, Arcanum, on behalf of the CAA, can now perform independent ASSURE Cyber Audits against the organisations Cyber Assessment Framework (CAF) for Aviation. Arcanum’s ASSURE team have broad exposure to the aviation industry as well as vast experience with Operational Technology (OT) systems.
