Tumbleweed announced the latest addition to its line of e-mail security appliances, the high-end MailGate Appliance 6500 designed
for companies with 10,000 employees or more.
The appliance can process more than 1 million messages an hour and is aimed at companies looking to simplify their e-mail
security strategies by consolidating to fewer products that can do more things, the company says.
Based on a hardened Linux kernel, the Mailgate 6500 protects corporate systems from e-mail-borne threats with features such
as Virus Outbreak Protection, which uses pattern detection to identify new virus attacks even before antivirus companies release
signatures, the company says. The appliance also blocks 99% of spam coming across e-mail channels in multiple languages.
The Mailgate 6500 offers policy enforcement features, so organizations can monitor outbound messages to be sure that sensitive
company information or data covered by regulations isn’t leaving the company. Rules-based TLS (Transport Layer Security) encryption
is included, so messages that need to be secured before leaving an organization can be automatically encrypted.
In addition, the MailGate 6500 can stop as much as 80% of an organization’s e-mail load before it hits the network by blocking
malware at the edge, the company says. The appliance uses traffic-shaping techniques that identify suspicious senders of spam,
virus-laden messages and malware, as well as attempts to launch directory harvest and denial-of-service attacks, and throttles
back or blocks those messages, cutting down significantly on the amount of e-mail that needs to be scanned.
