Where we operate
Johannesburg covered.
Street by street.
Sentinel operates dedicated patrol vehicles in each coverage zone, not shared across the city. When your alarm triggers, there is already a Sentinel vehicle nearby, not driving across from another suburb.
Coverage outside the listed zones is available subject to assessment. Contact us to discuss your area.

Client feedback
What they say about
having Sentinel on call.
“We had an attempted break-in at 2am. Sentinel had an armed officer at our gate in just under three minutes. The response was professional, thorough, and genuinely reassuring. We would not use anyone else.”
Gert van der Berg
Property owner, Bedfordview
“Managing 340 units means security is my biggest operational concern. Sentinel's guarding team is disciplined, punctual, and their daily reports make my job significantly easier. Reliable in the real sense of the word.”
Nomvula Dlamini
Estate manager, Fourways
“After two break-ins with our previous provider, we switched to Sentinel. Eighteen months later, zero incidents. Their CCTV monitoring team flagged a suspicious vehicle before anything happened. That proactive approach is exactly what we were looking for.”
Marco Ferreira
Business owner, Germiston
