Security and peace of mind —
since 1993
Force Delta is one of the first private security companies in Bulgaria. Three decades on, we protect the country’s most sensitive sites — from foreign embassies and government institutions to leading banks, telecoms and thousands of private clients.
Thirty years of setting the standard
Force Delta Ltd was founded in 1993 by Konstantinos and Trayanka Orfanidis — at the dawn of Bulgaria’s private security sector.
A high professional standard, a motivated team and a readiness to adopt new technology quickly earned the company a leading place in the market — a position we hold to this day. In many cases we have been the first in the industry to introduce new technology.
To meet our clients’ needs through security services of uncompromising quality.
24/7 monitoring centre
The monitoring centre is the heart of the company and never stops — 365 days a year, with no weekends or holidays. Trained operators watch signals from every site in real time, verify the event and dispatch the nearest patrol by GPS, and every action is archived.
We run triple-redundant fibre connectivity and backup power, so there is no interruption even during a failure. When needed, we have a direct line to the 112 emergency number, the Ministry of the Interior, the Fire Safety and Civil Protection Directorate and the emergency medical service.
