Featured Reviews

Odai Halawani - PeerSpot reviewer
It's an easy and effective solution, especially for device profiling without agents
Forescout Platform's most valuable aspect is its excellent device profiling for devices without agents, which is crucial for our work due to challenges with agent-based devices. Its isolation and blocking actions are particularly effective for network security. The device compliance feature helps us ensure device compliance through immediate actions like updating antivirus software. We have already integrated Forescout with antivirus and vulnerability assessment tools, allowing it to monitor vulnerability scores and automatically isolate devices if critical vulnerabilities are detected.
