What is Kerio Control?

Kerio Control is a unified threat management (UTM) system. Unlike a basic router that simply passes traffic, a UTM combines multiple security functions into a single appliance (software or hardware). Kerio Control integrates:

• A stateful inspection firewall.
• VPN capabilities (IPsec and SSL).
• Intrusion Prevention System (IPS).
• Content filtering and antivirus.
• Bandwidth management.

Version 9.4.2 continues this tradition, focusing on performance stability and compatibility for virtual and hardware deployments.
