Traditional NAC vs Dynamic NAC

Combine the strengths of Infrastructure NAC with an easy to deploy software approach
. Compliant PC’s act like “Neighborhood Watch”
. The existing normal PC’s become the infrastructure (enforcers) to quarantine rogues
. Enforcers manage ARP to control and limit a Rogue ability to send/receive traffic on the network
. Enforcers watch for new endpoints, using ARP redirection to protect the network and community

DNAC Strengths
. Zero network upgrades or changes (Low TCO)
. Scales cost effectively across multiple subnets
. Authentication agnostic (Windows Domain, 802.1x, other)
. Friendly fail-open design
. Extremely responsive quarantine and remediation mechanisms
