Unified Threat Management

Say good bye to viruses, spyware, drive-by downloads, Trojans, and the bad guys who use them to damage companies just like yours. Kerio Control's intrusion prevention system transparently monitors and maps user behaviors such as inbound and outbound communication. The Kerio Web Filter blocks more than 53 types of suspicious web content while also blocking users from trying accessing sites known for carrying such content. The powerful Sophos anti-virus engine, powered by multicore processors and other high-octane configurations, protects your gateways in real time, and continually keeps itself updated.

  • Integrated gateway anti-virus, web filter, P2P networks filter, intrusion prevention system, file-type blocker, flexible keyword and web object filter.


Kerio Control's VPN (Virtual Private Network) features allow you to consolidate multiple office networks into one super-productive superhighway. Build as many site-to-site or client-to-site channels as you want, regardless of what platforms the various endpoints are using. Set up persistent modes or on-demand modes to suit your needs. The use of such standard encryption algorithms as Secure Socket Layer for the control channel and Blowfish for the data transport ensures compatibility and flexibility. Oh, and don't worry about viruses either – Kerio Control's integrated anti-virus component keeps a watchful eye on any potential bugs running along the VPN.

  • Multiple site-to-site and client-to-site VPN tunnels.
  • Prevent simultaneous editing of a shared file.
  • Includes a cross-platform VPN client for Windows, Mac, and Linux.

Quality of Service

A network isn't a network without consistent uptime – another area in which Kerio Control shines. Its “smart” bandwidth management knows how to guarantee maximum bandwidth for high-priority traffic by restricting bandwidth for the lower-priority traffic. You can create different sets of rules depending on the suer or group, the protocol, the DSCP value or other defined parameters. Realtime traffic charts show you exactly how your network traffic is flowing. Automatic link-load balancing keeps multiple connections running like a champ, while active/active or active/passive failover keeps your uptime, well, up.

  • Multi-port active/active and active/passive configurations with automatic connection failover and link load balancing.
  • Bandwidth Management easily reserves and caps bandwidth for specific network traffic types.
