Security scanner probes 1 million IPs per hour for scary vulns | ICT Security-Sécurité PC et Internet | Scoop.it
The service can scale linearly, so two boxes are twice as fast.

 

Immunity Inc. has released a security tool that can scan an astounding 1 million IP addresses per hour, discovering if they're susceptible to hacks that allow attackers to hijack servers or retrieve sensitive data.

 

The entry-level package of Swarm, as the service is called, is a 4U server that includes 10 virtual machines.
