Email Defense

Mailspect Defense protects email gateways and servers from spam, viruses, phishing, fraud and Internet attacks.  It is a best-of-breed Control Panel used to configure, monitor and update a multi-layered suite of defenses.  Mailspect Defense protects your organization from the ever evolving threats on the Internet at the pre-scan, scan and post-scan phases of email processing.  Using a high-speed, scalable email filter called mppd and a state-of-the-art quarantine solution called Message Viewer, Mailspect Defense offers email security for businesses, governments, schools and Internet service providers.

Mailspect Defense puts control of dozens of email security techniques, technologies and analytics in the hands of the systems administrator.

Mailspect Defense secures the the perimeter” by blocking “blacklisted” IP addresses and attackers.  This pre-scan processing eliminates at least 67% of spam before it enters the email processing queue at the gateway or server level.

“Start your engines”. Mailspect Defense combines Open Source or commercial anti-virus and antispam engines with content filters to let the “real email” through while blocking spam, viruses and offensive content.  By stringing filters together, Mailspect Defense can solve ‘corner conditions’, i.e., special requirements of a particular industry or regulatory environment.

“Nothing compares to Hu-mans”. In post-scan, Mailspect Defense presents ‘gray’ emails in quarantine digests in the Message Viewer for end-user and administrator processing.  Quarantine choices build user-specific white and black lists that are re-used in the pre-scan front-end.

Mailspect Defense is unique in its ability to combine flexibility with effectiveness in one easy-to-use platform. It is architected for efficiency.  It lets administrators add, configure, combine and modify email filters to ensure maximum security without blocking “real” email.

The system has three components:

  • Message Filter or mppd
  • Control Panel
  • Message Viewer

The bottom line is that Mailspect Defense is faster, more accurate, more sophisticated and less hassle to administer than Open Source spam and virus filters and much more flexible than rigid, single-point email filtering appliances.
