Microwall Bridge (Firewall)


Firewall bridge without modifying the IP setup

The Microwall Bridge segments sensitive network areas without changing the IP configuration of the components which have been isolated. The preferred area of application is therefore the easiest possible, add-on security expansion of existing infrastructures.
