— About Coreitech

A cybersecurity company built for London businesses

Coreitech is a specialist cybersecurity and managed IT company headquartered in London. We exist to bring enterprise-grade cyber security to London SMEs — businesses that face the same threat landscape as large corporations but rarely have the internal resources to match it.

Our security team includes certified cyber security engineers, Microsoft security specialists, and former incident responders. We don't outsource to offshore teams. Every alert, every ticket, every consultation is handled by our UK-based team — people who understand the London business environment and the specific threats facing your sector.

We protect over 200 businesses across London, from City of London law firms and Canary Wharf financial services firms to West End creative agencies, healthcare practices, and charities. Our approach is proactive — monitoring your environment 24/7 and stopping threats before they become incidents.
