Clearswift is a communications security company, providing web and email filtering for 25 million end users, at around 17,000 business customers. It has offices in six countries worldwide, with headquarters in Theale, near Reading, UK.
SECURE Web Gateway
New product built on MIMEsweeper platform but with much simplified user interface and operations management. Gateway includes, Linux OS, AV, Anti Malware etc. + Reporting all in a single deliverable. Can be deployed on virtual environments, own hardware or purchased as an appliance.
SECURE Email Gateway
The replacement product for MIMEsweeper. As with SECURE Web Gateway, it provides a much simplified user interface and operations management. Includes Linux OS, anti-virus, anti-malware, and much improved spam detection and reporting in a single deliverable. Can be deployed on virtual environments, own hardware, or purchased as an appliance.
MIMEsweeper was originally a mail filtering product of Content Technologies.
In April 2005 Clearswift began to market an SMTP appliance based upon the technology.
Clearswift has extended the MIMEsweeper line to include web and instant messaging filtering. These are marketed as protecting against the leakage of confidential company information on social networking sites - Clearswift argues that instead of banning Web 2.0 sites and services entirely, businesses can actually gain a competitive advantage by making use of them, provided their use is monitored.
Note Clearswift sold the Deep-secure, Bastion and Flashpoint products in Dec of 2009.
Bastion is a stand-alone application level firewall server, designed as a secure bastion host for running content filtering or inspection for X.400, SMTP, X.500 and SNMP. It uses the Trusted Solaris operating system, and has been assured to CC EAL4 .
DeepSecure is a high assurance boundary protection guard for X.400 and SMTP providing email content policy enforcement, including secure inspection of S/MIME signed and encrypted messages within the assured protected environment provided by Bastion. DeepSecure provides central message policy management for distributed DeepSecure, and distributed management of security label policies using X.841 SPIFs. DeepSecure has been evaluated to CC EAL4 and selected in major military procurements.
FlashPoint is a Military Messaging client and server product set that is unique in its use of the 1994 X.400 Message Store access protocol P7.
NET-TEL was rebranded as Clearswift in 2001, after a round of venture capital fundraising.
In 2003, the company received $6.07 million from its shareholders, including venture capital funds managed by Amadeus Capital Partners, BA Capital Partners, Cazenove Private Equity, and Kennet Partners. Also, it was reported that Clearswift were the providers of a new email filtering system at the House of Commons, responsible for blocking Welsh language emails as "inappropriate content", and preventing MPs receiving copies of a Sexual Offences Bill. Clearswift would not confirm that the House of Commons was a customer, citing customer confidentiality reasons.
In January 2008, failure to renew a domain name caused loss of email services to 5% of Clearswift's customers.
