Foobar Linux is Linux distribution by Foobar Oy (Inc.). It's based on prominent Enterprise Linux distribution which released it's source code under GPL license. We added data security and usability applications over this stable base. System is build to be easy to maintain as whole.
We did build our own Linux distribution to offer our customers better service. Because whole system is in our control, we can do rapid changes if required. We can fix bugs original distribution didn't fix for some reason.
Foobar Linux is especially strong in security being the first Linux distribution including Openswan IPsec VPN software. Openswan is one of the most compatible IPsec implementations which several IPsec program vendors use for interoperability testing.
Linux kernel includes Netfilter firewall. We use Shoreline Firewall (Shorewall) which makes maintaining complicated firewall rulesets easy.
Clam AntiVirus toolkit is included in distribution. Also included are necessary programs to build email or web traffic content filtering systems.
High availability is achieved with Linux-HA Heartbeat programs together with Linux Virtual Server load balancer. These together do make building biggest server clusters possible.
