WirelessWall is TLC-Chamonix's product (acquired from Cranite Systems) to provide security and mobility for 802.11 and 802.16 networks. They're one of only a couple of vendors that meet the DoD standards for security--FIPS 140-2 certified protection at Layer 2. They're using 802.1x (EAP-TTLS) and AES to do authentication and encryption, and also provide seamless subnet mobility. TLC is also the only vendor in the space to provide a software-only solution, meaning that they run on off-the-shelf servers rather than a proprietary appliance--we're using HP servers at $1000 a pop, versus other vendors' appliances that are 2-5x that. They've got a cool solution for tying into Active Directory, too--just run a DLL on a local Windows machine, and all the AD stuff gets tied into their Policy Server dynamically. Plus, the licensing model is wicked cool--TLC charges based on simultaneous users (concurrency), rather than seats, which meant we were able to roll out a gold disk to all our users and never had to touch the TLC client application. I can't even quantify what that saved in terms of time versus having to do a license on each user's machine. And, since all the seats will never be on the network at once, you only have to pay for concurrency...TLC claims that the typical concurrency numbers are about 50%, meaning that you're really only paying for half as many clients as you might have to with other solutions. See wirelesswall.com for more information.
