Fortinet, a leading network security provider and the worldwide leader of unified threat management (UTM) solutions, has announced a new release of its FortiOS 4.0 operating system for the FortiGate product family, including FortiGate-3140B multi-threat security appliance.

The broad advancements offered in the FortiOS 4.0 MR3 operating system introduce wireless controller extensions that support automatic provisioning of wireless access points, detection and suppression of rogue access points, among other things, the company said in a statement.

The upgrade also introduces active profiling and flow-based threat inspection enhancements to the OS that already integrates firewall, virtual private network (VPN), intrusion prevention (IPS), antivirus, application control and many other security technologies, it said.

"With the release of FortiOS 4.0 MR3, powerful new security features and performance enhancements are now available for FortiGate consolidated security appliances", the company said.

The advanced FortiOS operating system expands the wireless controller capabilities of any FortiGate running FortiOS 4.0 MR3.

These capabilities improve security by enabling role-based access control to limit access to regulated, proprietary, or confidential data based upon a user?s role, among others.
