Thanks for the info. We have looked into Common Criteria but it'll likely take some time as it's an involved process.
As of this point, there is no plans for a FIPS-2 compliant Load Balancer. However we have that capability on our high end Web Application Firewall (Model 963) that contains a FIPS HSM card. The WAF also has load balancing capabilities and has many of the same functionality as the Barracuda Load Balancer.
The Barracuda WAF uses FTPS. There is some documentation on FTPS via the online help guide. Just click on "Help" on the "Basic->Services" page. For the latest documentation, you can always look at the one stored on the online demo at waf.barracuda.com. User/password is guest/guest.
