It also provides endpoint security through an integrated device firewall and client inspection, the highest level of encryption for network usage as well as a granular control of user access. Setting up the server and user access takes a lot of time without doubt, but once you have the solution in place you can easily expand as your need grows.

Each AppGate server can handle up to 12 internal security domains or segments.

Each and every user and administrative activity is logged so a complete and transparent tracking and monitoring system is available. This also helps tremendously in security compliance and also enables the system to send alarms to external systems when an unusual activity occurs. Over all, the AppGateSecurityServer provides a much better approach to security than the traditional firewalls and is even more beneficial than traditional solutions due to its scalability.
