Spam Filtering

 INS  uses Red Condor spam filtering from Edgewave, Inc. Inbound – Incoming email  must pass through successive layers of SMTP session level defenses before  reaching the recipients inbox. Each level looks for and removes specific  threats such as content analysis, virus detection, sender profiling.


Outbound – Outbound traffic is inspected to  identify computers that have been infected and converted to a  "zombie" or botnet client. Zero-Minute-Defense – Employs real-time  knowledge gathered from a worldwide sensor network and uses it to create new  detection and protection rules, which are then sent as updates on a continuous  basis.
