A version of the SECURE File Gateway is OEM’d and sold by BAE.
SECURE ICAP Gateway
The SECURE ICAP Gateway is a variant of the SECURE Web Gateway which is designed to work with the ICAP interface. Specifically with Blue Coat devices. It brings the Clearswift Deep Content Inspection and DLP functionality to the Blue Coat proxy. It can be deployed on virtual environments, own hardware, or purchased as an appliance.
SECURE Exchange Gateway
The SECURE Exchange Gateway is a variant of the SECURE Email Gateway. It has an additional Interceptor for Microsoft Exchange which enables all internal email traffic to be subject to the Deep Content Inspection and DLP policies that the other Clearswift gateway products have.
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.
In September 2013 Clearswift introduced some new options for their SECURE Gateways, Adaptive Redaction. There are three options available.
- Data redaction: Removal of data (text) from email, web pages and files (including email attachments).
- Document sanitisation: Removal of ‘hidden’ data, such as that held in document properties and revision history from email, web pages and files (including email attachments).
- Structural sanitisation: Removal of active content from web pages and files (including email attachments).
Clearswift sold the Deep-secure, Bastion and Flashpoint products in Dec of 2009.
