CSA Cyber Information

Modern cyber resilience demands more than isolated controls. It requires assurance across every layer of your organisation. CSA Cyber is the UK’s benchmark for accredited cyber expertise, delivering end-to-end cyber resilience to high-profile organisations and critical sectors worldwide. With one partner, organisations gain access to a fully integrated capability: a true 24/7 Security Operations Centre, dedicated in-house Red and Purple Teams, and accredited risk and compliance consultants working as one. Holding one of the most comprehensive accreditation portfolios in the UK cyber sector, our approach is built on independently validated expertise. The result is clarity, confidence, and resilience that stands up to both real-world threats and regulatory scrutiny. Founded in 2013 by senior security professionals with backgrounds in national-level cyber operations, our UK-based, security-cleared teams are trusted to protect complex, high-risk environments where assurance is non-negotiable. CSA Cyber is part of the FluidOne Group since its acquisition in 2020.
