Aruba ClearPass Policy Manager and Microsoft Defender ATP deliver a coordinated framework to ensure compromised endpoints are denied admission to the network, or quickly quarantined, when they show Indicators of Compromise (IoC). The ability to make intelligent access control (NAC) decisions based on endpoint threat telemetry is a critical capability as more unprotected and un-secured devices attempt to connect to your network. Without rigorous endpoint threat protection and context-aware network access control, these endpoints present an expanding attack surface that dramatically increases the risk of a security incident including the exposure of sensitive information.
