SEG Core — managed IT, cyber security and access control. One contractor · one number.
Home / Services

Three services, one accountable team.

Managed IT support, cyber security and building security — designed, installed and supported by the same engineers, with the cabling and electrical work included rather than subcontracted.

What we do

Everything on one contract

Most businesses end up with an IT provider, a CCTV company and an electrician — and three people to blame when something stops working. These three service lines cover all of it.

Also available

Wi-Fi, networks and structured cabling

Wireless surveys, network installation and structured cabling are delivered by SEG WiFi, our sister company inside the same group — the same engineers, the same accreditations, and it can go on the same order.

How that works

Not sure which you need?

Most enquiries start as one thing and turn out to be another. A free review looks at the whole estate — support, security, network and building — and tells you plainly what needs doing and in what order.

What that gets you

  • A larger pool of directly employed engineers than an IT provider this size would normally have — and a wider range of trades among them
  • Electrical accreditations, insurances and method statements already in place for work in live commercial buildings
  • One order, one programme and one invoice, whichever brand does the work
  • Nobody subcontracted in, and nobody to point at when something stops working
