Clearswift simplifies enterprise Web security with MIMEsweeper™ Web Appliance

Appliance provides comprehensive web security and policy management to enable Enterprise Content Governance

REDWOOD CITY, Calif. – November 28, 2006 – Clearswift today continued its campaign to simplify content security with the launch of its enterprise-class “plug and play” web security appliance, the MIMEsweeper Web Appliance.

The brand new MIMEsweeper Web Appliance combines the most sophisticated content security engine on the market today with the world’s number one URL blocker and leading anti-virus and anti-spyware capabilities to deliver the most comprehensive web security appliance on the market.

“The explosion in spam and email viruses in the late ‘90’s ensured that protecting the email gateway was pushed to the top of the agenda for organizations. The recent rise of web threats such as spyware and the silent threat of data leakage are now alerting businesses to the need for stronger web security solutions, but point solutions which only address spyware or URL blocking won’t solve the web security threats facing organizations today,” Clearswift’s Chief Operations Officer, Ian Bowles, said.

Meeting the Needs of Business Leaders

"The MIMEsweeper Web Appliance’s ability to tackle these threats, as well as protect against issues such as preventing confidential information leaking via webmail or blogs not only enhances security but allows organizations to enforce company security policies far more effectively for robust corporate governance,” said Mr. Bowles.

“This is the industry’s only web security appliance to offer full bi-directional content security, so not only does it stop inbound threats but it also protects against the threat of losing confidential information via the web,” he said.

Meeting the need of Security Professionals

Mr. Bowles said the launch of the MIMEsweeper Web Appliance demonstrates Clearswift’s continuing drive to simplify IT security without compromising on enterprise class protection.

“We are committed to easing the burden on IT administrators and are delighted that we can now offer our premium web security product as an appliance to help combat the constant barrage of threats on the web,” he said.

The MIMEsweeper Web Appliance covers all threats in just one box, meaning that IT staff will not lose valuable time managing multiple systems.

It features Clearswift’s award-winning, intuitive GUI which eases day-to-day management. Further benefits which lower the admin burden on IT administrators include granular policy management, powerful reporting functions and policy wizards, and a 30 minute installation.

Peace of mind through enterprise-class protection

“Unlike some competitive offerings, Clearswift’s content security products use rigorously tested, enterprise-class components which have been developed from years of web content security experience as opposed to freeware. This gives our customers absolute confidence that they can solve increasingly complex web security challenges as their organization grows,” said Mr. Bowles.

Further benefits include granular policy management, powerful reporting functions and policy wizards. The Appliance is capable of supporting thousands of users and the most complex environments.

“In my opinion, the MIMEsweeper Web Appliance successfully brings together the tried and tested MIMEsweeper content scanning technology with a comprehensive and intuitive user interface to deliver an effective solution that administrators will be able to implement quickly and maintain efficiently”, commented David S. Carr, Chairman of the independent MIMEsweeper User Forum.

Multipe ’best of breed" components

The launch of the MIMEsweeper Web Appliance also marks the beginning of Clearswift’s relationship with anti-spyware specialists, Aluria Software, now part of EarthLink, Inc (NASDAQ: ELNK) Value Added Services (VAS) business unit. Aluria’s spyware definitions database is one of the largest and most definitive in the world, and is fully supported by one of the most dynamic and aggressive spyware research teams in the industry. It benefits considerably over competitors offerings by having direct ties to over 5 million EarthLink ISP commercial and consumer subscribers thus enabling them to identify new spyware threats in real time.

“Aluria’s renowned credentials in the anti-spyware market perfectly complement Clearswift’s enviable track record in the content security industry, making for a very strong partnership which will deliver the most comprehensive content security solutions for our customers,” Mr. Bowles said.

In addition, the MIMEsweeper Web Appliance comes pre-loaded with multi-award winning, state of the art protection from Kaspersky Lab, provider of the world’s most immediate protection against IT security threats, including viruses, crimeware, hacking, phishing and spam. A built-in URL list completes the solution, with more than 18 million URLs and over 2 billion web pages cited by a professional research team using state of the art automated tools and real-world customer submissions.
