Built on One
Clear Principle
Incident Response Group (IRG) was founded by Ian Nicholson, a former Royal Navy engineer and firefighter who has spent the last decade leading incident response and threat intelligence services for UK enterprises, government bodies, and SMEs.
IRG was built around one clear principle: cyber defence must be available to everyone. We provide incident response, forensic investigation, threat intelligence monitoring, tabletop exercises, and readiness planning for organisations across the UK.
Our experience is hands-on. We’ve led crisis management calls at 2 a.m., contained live threats under pressure, and built the frameworks that keep clients resilient afterwards. Ransomware, data breaches, insider threats, credential compromise — across policing, central government, critical infrastructure, and private sector.
No Scare Tactics
We don’t rely on fear to sell services. Clear, honest assessments and practical guidance.
No Overstated Capability
What we say we can do, we deliver. Our track record speaks across hundreds of incidents.
No Empty Promises
We help you understand what’s happened, limit damage, recover confidently, and prevent recurrence.
