Once upon a time, we were just a small family-run security firm called Hedgehog Security — born out of late nights, endless coffee, and a frustration with how reactive the world was to cyber threats. Back then, the idea was simple: help organisations detect problems before they become headlines.

Today, that idea has grown into UK Cyber Defence, a team of dedicated experts who live and breathe active cyber defence. From our 24 × 7 × 365 Security Operations Centre, we protect businesses, governments, and critical industries against the kinds of threats that don’t take weekends off.

Our work spans Managed SOC and SIEM, Threat Hunting, Incident Response, Penetration Testing, and vCISO services — all grounded in real-world experience, CREST-certified practices, and ISO-accredited standards.

At the heart of everything we do are three pillars that shape how we operate:

Detect — See what others miss. We combine human expertise with AI-driven visibility to uncover threats in real time.

Defend — Act fast. We respond to incidents and contain threats before they impact business continuity.

Disrupt — Strike back. Using deception, counter-techniques, and deep threat intelligence, we turn the tables on attackers.

Cyber security has changed — it’s no longer just about protection; it’s about resilience, adaptability, and precision. That’s why we don’t just monitor systems; we defend them. And we don’t just defend; we disrupt those who try to cause harm.

If that sounds like your kind of security, you’ll fit right in here.
