Who we are, how we work, why clients trust us, and who will come to your premises.

Who we are

40 years in the Greek security market.

Since 1986, AT Security has designed and installed complete security systems in Thessaloniki with one constant criterion: every project must stand the test of time. A design tailored to the space, equipment from leading manufacturers and technicians who know the system from day one.

Forty years on, our clients include leading Greek businesses, organisations and hundreds of homes. With ISO 9001:2015 quality certification and prompt technical support from our own team, the relationship with each customer does not end at handover — that is where it begins.
