Sentriant is a security appliance that secures the network interior against rapidly propagating threats including Day-Zero attacks. Sentriant is designed to work in conjunction with Extreme Networks Security Rules Engine - CLEAR-Flow.Sentriant uses behavior-based threat detection methods (no signatures, no heuristics) to detect threats � including new threats for which no signatures exist at the time of attack. It also includes a sophisticated early warning system that employs unused IP space to identify threats. Sentriant is not an in-line device, creates no performance impact to networks, and cannot jeopardize network availability � even while the network is under attack.Sentriant incorporates a threat termination technology aggressive, protocol-independent, automated threat termination capability. This technology does not use software desktop agents, TCP resets, or switch-dependent VLAN shunting to compartmentalize an infected end-point.
