Tumbleweed Releases MailGate 3.6

  
    
  
  
    
      Tumbleweed® Communications Corp. 
      (NASDAQ:TMWD), an industry leader in managed file transfer, email 
      security, and identity validation, today announced MailGate® 
      3.6, the latest version of its award-winning email security product. 
      MailGate 3.6 adds a number of compelling capabilities for government 
      agencies and regulated industries, including S/MIME encrypted email for 
      data loss prevention (DLP), a granular employee or user-based DLP 
      reporting feature, and integrates the latest elliptic curve 
      cryptography, which will help streamline future Federal Information 
      Processing Standard (FIPS) certification.
    
    
      “MailGate 3.6 answers the call from many of 
      our public, regulated and government customers – 
      governmental agencies, in particular, will benefit significantly from 
      these enhancements,” said Joe Fisher, senior 
      vice president of product management at Tumbleweed. “MailGate 
      routinely gets exceptional scores in independent 
      product reviews, particularly for our strong DLP policy engine, 
      market-leading encryption, and superior interface. The rally cry for 
      data loss prevention is everywhere, and Tumbleweed is one of the only 
      vendors to successfully and effectively integrate DLP capabilities into 
      our complete product suite. Within MailGate, these valuable outbound 
      capabilities help protect sensitive information sent via email, which is 
      arguably the most-used business communications channel today.”
    
    
      In 2007, Tumbleweed received 140-2 Level 1 certification, the benchmark 
      standard for government agency data security, for the security kernel 
      used in its suite of products. Tumbleweed’s 
      customers include government agencies such as the U.S. Department of 
      Defense, U.S. Department of Homeland Security, all four branches of the 
      U.S. military, and numerous state and local governments. MailGate 3.6 
      provides customers with gateway inspection of S/MIME encrypted email for 
      both inbound and outbound encrypted mail, thus helping prevent costly or 
      dangerous data breaches. In addition, the added SMTP extension includes 
      an authentication step that helps ensure the true identity of the sender 
      is known.
    
    
      MailGate DLP policies will drop any encrypted message that cannot be 
      decrypted and reviewed for content scanning or return the message to the 
      sender with instructions on how to send encrypted mail through MailGate. 
      Additionally, MailGate 3.6 provides a comprehensive employee/user-based 
      DLP “summary” 
      report, providing insight into employee or user activity that could 
      expose sensitive data.
    
    
      Also integrated is NSA-approved elliptic curve cryptography technology, 
      a move that provides one of the highest levels of security while 
      streamlining future FIPS 140-2 and Suite B compliance renewals. FIPS 
      140-2 is the security requirement for cryptographic modules as defined 
      by the National Institute of Standards for Technology (NIST). Suite B is 
      the set of cryptographic algorithms recommended by the National Security 
      Agency (NSA) to secure classified and unclassified communications.
