With Cyber Security becoming an increasingly important factor in designing modern Ethernet networks ComNet have launched an industry first edge security feature that is both simple, secure and easy to configure and use.

The ComNet exclusive Port Guardian feature has the capability to physically disable a port if unauthorized access is detected.

The value in Port Guardian comes in situations where network intrusion is attempted by disconnecting an IP addressable device at the edge to connect to the network. When Port Guardian senses this disconnect, an SNMP notification is sent to the head end and the affected port is physically locked out, preventing access. The network administrator can re-enable the port once the threat is eliminated. This feature also thwarts access through “Spoofing” by disabling the port as soon as an interruption is sensed.
