Fortinet is a vendor for security appliances, mostly known for the FortiGate firewall. But there are some other products like a Database Firewall, Wireless APs, etc.
The firewalls include a lot of features without a mad cisco-like licensing scheme - they're just there and usable: IPSec-VPN, SSL-VPN, IPv6, OSPF, BGP, IS-IS, virtual firewalls on one device ("VDOMs"), HA, WAN-Optimization (using Riverbed technology?), Wireless controller, etc, etc. Subscriptions for Antivirus/IPS patterns and URL-Filter can be added optionally.
