The scope of the spam problem is enormous, ongoing and costly. Spam, and spam-borne malware, is estimated to cost U.S. businesses $712 per employee per year and constitute a staggering 95% of all email messages. The Federal Trade Commission has declared spam to be a significant global tool in the propagation of financial cyber crime, and the IRS has placed phishing emails (which are aimed at stealing personal financial data) at the top of their 2008 list of the 12 most serious tax scams. The current landscape is dominated by blended threats that incorporate multiple spam-borne malware.
The SpammerTrap(R) email security solution addresses ongoing security threats by effectively filtering out 99.9% of spam and delivering legitimate email in virtually real time, using a unique combination of open source tools and proprietary software including more than 40 real-time blacklists, heuristics filtering, and a reputation filter that leverages four separate databases. It also incorporates the most sophisticated email firewall available today, which integrates these advanced functions:
Email Sender/Recipient Verification: By blocking emails with invalid addresses during the email envelope exchange step in the Simple Mail Transfer Protocol (SMTP) session, the SpammerTrap is able to avoid processing and queuing up the entire message. Similarly, email sender name and address are funneled through a unique sender reputation filter, with unsavory addresses blocked before they can enter the client network.
Denial of Service (DoS) Attack and Directory Harvest Protection:DoS attacks overwhelm targeted email systems with so much bogus mail that they are unable to process legitimate email communications. SpammerTrap firewall technology monitors network connections passing through it, enabling it to isolate DoS attacks from valid traffic and launch its attack prevention arsenal. The firewall also maintains a local cache of valid recipients that can be updated from any LDAP source in real time or populated from a file import. When an attacker sends to an invalid address, the email is rejected with an error to the attacker, thwarting the harvest attempt.
Forged Header Detection: Forged or spoofed headers constitute identity theft when a spammer uses a legitimate, stolen email address to send malicious email to thousands of businesses. Reverse directories are available online to help trace many email sender addresses, but there is no need to resort to such tools with the SpammerTrap firewall.
With the SpammerTrap Email Security Gateway and its unique email firewall, clients of all types and sizes receive the most advanced protection from spam-borne threats available today. Advanced technology and rich features, combined with exceptional efficiency, deliver the best price-to-value ratio in the industry.
