Avenger Security provides reliable fire alarm and burglary alarm services to commercial and residential properties throughout the greater San Antonio area. Find your city below.
From the heart of downtown San Antonio out to the surrounding suburbs and small towns, our certified technicians are ready to install, service, and monitor your alarm system. We're locally based — which means faster response, friendlier service, and a real understanding of Texas fire code and security needs.
Please note: We do not currently serve Austin or points beyond — Austin is outside our reasonable response gauge.
