Crossbeam Systems has started shipping a massive chassis-style, “unified threat management” (UTM) system based on an open Linux OS. The X-Series UTM server runs the companys Linux-based “XOS” OS, and targets highly scalable firewalls and other security applications for large data centers and service providers.
