UK Cyber Defence

UK Cyber Defence is a Duxford, Cambridgeshire-based cybersecurity company serving organisations across the UK and Europe. Established in 2009, it brings offensive testing, security operations and advisory services together in one team, helping clients strengthen their defences without having to build an in-house security department.

Its services include SOC365, a 24/7 managed security operations centre that monitors systems and supports threat detection, incident response and containment. Clients can also arrange penetration testing and red-team engagements across networks, applications, cloud and other environments, with practical reports and remediation guidance. Virtual CISO support provides security leadership, risk management and board reporting on a retainer basis. Consulting covers compliance, security engineering, readiness assessments and incident response exercises. The company also guides organisations through Cyber Essentials and Cyber Essentials Plus certification. Its approach is built around detecting threats, defending systems and disrupting attackers, with services intended for regulated, critical and busy organisations.
