Network Access
Network access control ensures visibility, control, and automated responses for all devices and systems comprising your network. Visibility involves forming profiles of each device connected to your network. The versatility of the network is enhanced when access is granted to outside products like switches, routers, and access points—without compromising the security and integrity of your IT infrastructure. Network access also defends your systems through responsiveness. As soon as a threat appears, it can be automatically eliminated. A network access system accomplishes this by changing configurations to keep your critical components and data safe.
