Cloud-Assisted Antivirus and Targeted Attack Detection for Windows

Cezurity is an information security company based in Saint Petersburg, Russia, established in 2006. It publishes antivirus products for home users and for small and mid-sized businesses, plus a targeted attack detection service aimed at larger organizations. Its stated focus is finding infections already resident on a machine, including trojans, spyware, malicious browser extensions, and rootkits, rather than only blocking known files as they arrive. The company also licenses its detection technology to partners through an SDK program.

The consumer Scanner tool connects a computer to Sensa, the company's cloud analysis system, which examines the state of the machine and weighs it against what the service knows about clean and compromised systems, then reports hidden infections. Cezurity Antivirus adds resident protection on the endpoint itself. Antivirus.Business applies the same engine to servers and workstations, with a deployment the company describes as taking minutes rather than a scheduled rollout across the estate.

COTA is the cloud service aimed at advanced persistent threats, collecting system state from monitored machines and analyzing changes centrally instead of relying on endpoint signatures alone. The SDK program lets other vendors embed Cezurity detection inside their own products. The company's public site carries material dated through 2019, so buyers should confirm current product availability, pricing, and support directly with the vendor before planning a deployment.
