Listing roadmaps

What is GBEST?

GBEST is an intelligence-led simulated attack framework developed and managed by the United Kingdom’s Cabinet Office. It is derived from the Bank of England’s CBEST framework but is focused on building the overall Cyber Resiliency of UK government, its Departments, Agencies and arm’s length bodies.

GBEST engagements are highly rewarding engagements, providing organisations with a detailed understanding of their threat landscape and a clear roadmap to improving their security posture based on those relevant threats.

How to Procure GBEST from SecAlliance

SecAlliance is both a ‘G-CLOUD’ and a ‘Digital Outcomes and Specialists’ provider with Crown Commercial Services. Departments can procure directly from Security Alliance or via the two above-mentioned procurement frameworks.

Need to know more?

SecAlliance has a detailed knowledge of the framework. If you would like an informal discussion or briefing on the intricacies of GBEST, one of our Threat Intelligence Managers who has delivered an engagement would be happy to help.
