Insightix NAC ? Stateful Network Access Control. Insightix NAC delivers stateful network access control, ensuring that only authorized and compliant devices are allowed to access and operate on the enterprise network. Insightix NAC utilizes agentless Stateful Network Detection technology to maintain complete contextual information about the state of the entire network along with unique blocking and quarantine techniques that remove any dependencies on switches. Insightix NAC simplifies the rollout of network access controls. Insightix NAC is agentless and does not require network changes, specialized software or hardware or extended deployment efforts. Real-Time Device Detection - Insightix NAC leverages Insightix?s powerful Stateful Network Detection technology to maintain complete, accurate and real-time contextual knowledge about the state of the devices on the enterprise LAN. Insightix?s Stateful Network Detection technology automates the real-time identification, profiling (capabilities and properties) and location of all of the devices residing on the enterprise network. Based on the wealth of contextual IT infrastructure information gathered, Insightix NAC enables IT professionals to easily baseline their networks and authorize the devices that are permitted to access and operate on their networks. Once activated, Insightix NAC performs real-time device detection and authorization enforcement. Any device not authorized to operate on the enterprise network is denied connectivity as it attempts to access to the network. Network-wide Policy Enforcement - As an authorized device attempts to access the enterprise network, Insightix NAC immediately isolates the device using Insightix?s patent-pending Quarantine Silo technology by shielding it from other network devices while Insightix NAC performs posture validation checks. Using a rule-based policy engine, IT professionals can easily define the posture validation checks that are performed by Insightix NAC. Examples of these checks include checks of Windows-based operating systems to verifying the service pack level, presence of certain operating system patches, open network services and installation and activation of anti-virus software. Insightix?s Quarantine Silo technology ensures that network access is not granted to an authorized device until it successfully passes the network access control posture validation checks. Continuous Network Monitoring - Insightix NAC constantly monitors the state of the network and identifies in real-time any changes made to the profile of devices that are authorized to operate on the network. When a profile change is detected, Insightix NAC immediately denies network access from the device. Insightix NAC ensures that the properties of an authorized device, such as the MAC address, are not abused in order to prevent an unauthorized device masquerading as an authorized device.
