ISO 27001-certified Intersys provides cyber secure IT to organisations in the UK and across the globe. We harden our clients’ defences against cyber attacks and help them find new and more efficient ways of doing business. Intersys delivers across all sectors, including highly regulated industries. Our mission, always, is to support our clients’ growth through smart, secure IT.

Intersys is the Security First Provider, with a dedicated cyber security division overseeing our team’s work. With the current scale of the cyber threat, this level of security-hardened IT helps our clients stay safe in an increasingly dangerous world.

We have also developed a service-over-sales culture that puts solving problems firmly ahead of ‘selling kit’. This approach is championed by our leadership team who, unlike many similar businesses, are not sales people but technically accomplished cyber risk and IT professionals. This approach has led to an exceptionally high client retention rate.

Founder and CEO Matthew Geyman kickstarted Intersys, quite literally, in 1996, when he began providing fast-response IT services from his Triumph Daytona motorbike. Formerly an IT manager in the City, he grew frustrated by technical stagnation among in-house teams and relentless sales pitches from outsourced providers. Zipping across London, he developed an agile, service-focused business. Intersys now has 140-plus clients in the UK, India, New Zealand, West Africa and many more territories.
