Power of Two
BlueCat has partnered with Commtouch Software, an Israeli security company, to seek out and tag spam before it reaches your front door. It's like having a buddy in the post office throw out your junk mail before it gets to your house.

The vendor calls this optional feature recurrent pattern detection, or RPD. It watches the network for patterns of spamming behavior, prowling for waves of outbreaks and monitoring the speed of distribution inherent in spam blasts. When a large-scale spam attack is spotted, Meridius preflags offending messages regardless of language, content or origin and zaps them on their way through your door. As my test results have shown, RPD works--you wouldn't want to run the appliance without it.
Meridius 3.0 runs a hardened version of Linux on a 1U rack-mount 2.6-GHz Pentium 4 with 1 GB of RAM and an 80-GB drive. Like BlueCat Adonis, Meridius' front LCD provides basic administrative functions, eliminating the need for a keyboard or monitor. The management client works on Windows, Solaris, Linux and Mac OS X machines. The appliance also runs F-Secure's new antivirus engine.
