Spam Blocker

Block Spam at the Network Gateway

Spam Blocker enables administrators to block spam at the gateway before it ever reaches the users. Zero client installations and an intuitive GUI make it easy for administrators to:

• Leverage the best spam filtering techniques including Bayesian Filters, Razor, realtime block lists (RBLs), OCR for image spam and tarpitting
  

• Provide individual quarantines for each mailbox
  

• Filter SMTP, POP & IMAP

Web Filter

Control Web Content at the Gateway

Web Filtering enables administrators to enforce network usage policies and monitor user behavior. Zero client installation and category block lists make it easier for administrators to:

• Protect the network from malware on the web
• Block time-wasting sites like MySpace
• Conserve bandwidth by blocking video downloads

Protocol Control

Block Port Hopping Applications

Protocol Control lets administrators take back control of their networks from disruptive port-hopping applications like peer-to-peer applications or online games. Signature based layer 7 filtering makes it easy for administrators to:

• Conserve bandwidth by blocking applications like peer-to-peer that open multiple TCP ports
• Improve productivity by blocking IM & online games that evade firewall rules
• Write custom signatures for any protocol
