Fortinet Unveils SSL VPN, VoIP Security Updates

Firewall vendor Fortinet on Monday introduced updates to its FortiOS security operating system that add ISCA-certified SSL VPN functionality and VoIP security to its FortiGate series of security appliances.

Both enhancements, unveiled at Interop in Las Vegas, are slated to show up in the second half of the year in FortiOS 3.0 and will be free to customers with ongoing maintenance contracts for FortiGate appliances, said Anthony James, senior product manager at Sunnyvale, Calif.-based Fortinet.

The SSL VPN addition supports a clientless approach to remote access and includes technology to ensure end-point integrity before authorizing a network connection, James said. FortiOS also supports IPsec, which gives users the option of choosing which protocol to use in specific situations, he said.

The VoIP-related function is being added to address the growing need for firewalls to handle IP telephony applications, according to James. "VoIP doesn't play well with network address translation," he said.

Fortinet's technology works by opening ports as needed during the call-signaling phase and then closing them again as soon as the call ends, James said. Other firewalls open up a whole range of ports to accommodate VoIP traffic.
