Colubris says it's certified to be used by government agencies: The maker of fat access points claims to be the only AP that has achieved the Federal Information Processing Standard 140-2 certification. FIPS is a standard made by the U.S. and Canadian governments that sets how cryptographic software and data encryption must work in gear used by government bodies.
Colubris touts the added security that it builds into APs. It's unique for terminating IPsec VPNs at the AP. Colubris says that's a way to offload traffic from an existing VPN concentrator and allow an enterprise to re-use security profiles that are already set up for users getting on the LAN.
