Who we are
Sealmark Limited is a technology-led security company protecting organisations across Eastern Africa. We combine PSRA-certified security officers, AI-enabled surveillance, GPS-tracked mobile response and intelligence-led consultancy into a single, accountable security ecosystem.
Every service line — guarding, Vigilance360™ remote monitoring, SentinelGrid™ alarm response, FLEET360™ fleet intelligence, SHIELD™ personal safety, loss prevention, consultancy and investigations — is coordinated from our 24/7 National Command Centre, so incidents are verified before anyone is dispatched.
Sealmark Ltd is licensed by the Communications Authority of Kenya as an application services provider for tracking services, License No. TL/ASP/00349.
