Tumbleweed Communications, the pure play messaging security vendor, has announced new MailGate capabilities that will reduce accidental email data leaks and botnet-driven threats.

Enterprises have universally been plagued by cost and complexity, requiring complex data categorisation and hundreds of thousands of dollars to conduct basic outbound filtering.

"It is crucial for Asian enterprises to embark on preventive measures to ensure that critical data is secured from external and internal threats. As the saying goes, 'Prevention is better than cure’ and it is especially so in this instance. What may seem as a mild internal leak can have adverse effects leading to the loss of revenue and company market share. These are growing concerns among CEOs today,” said Stree Naidu, Regional Vice President, Asia Pacific & Japan at Tumbleweed.

The new MailGate capabilities extend data leak and content filtering functionality to enforce multiple policy actions on messages containing sensitive information based on user context, corporate rules and delivery methods like encryption.

It automatically filters certain confidential information, including specific credit card, social security, and CUSIP (banking/trading) numbers with a simple checkbox, making the enforcement of policies surrounding this data a best practice. The interface also provides extensive lexicons of financial, healthcare and offensive terms, with flexible word-weighting for granular control over a wide range of regulated information.

Additionally, MailGate's content filters can scan all inbound and outbound messages, and more than 300 types of attachments, including binary and nested files. To further protect data, MailGate also provides policy-based TLS encryption.

Botnets – armies of hijacked 'zombie' computers, used for distributed spam and virus attacks – have been particularly effective against antispam products that rely heavily on IP reputation databases. By hijacking new IP addresses without established reputations, botnets are often able to elude detection – delivering spam from distributed locations, and stealing new IP addresses when existing ones are identified.

MailGate offers a critical new defence against the growing problem of botnets. It can correlate distributed attacks and drop connections from newly hijacked IPs – even if they do not have an existing negative reputation. This is combined with MailGate's extensive MailGate Edge defence capabilities blocking directory harvest attacks, email denial of service attacks, and invalid recipients.

The newest MailGate capabilities will be available on MailGate Appliance. MailGate 3.5 is anticipated to be available from Tumbleweed and select channel partners in late July.
