clearswift - Gateway Encryption

The Clearswift SECURE Email Gateway provides an easy to use approach to providing secure email conversations. The technology enables customers to provide the privacy, authenticity and integrity of the communication that secure messaging offers, but without the complexity and high administration cost of other systems.

The SECURE Email Gateway with integrated encryption technology enables businesses to communicate with confidence and protects them from the risk of sensitive data loss.

Security using standard encryption protocols

The SECURE gateway supports both international standards of OpenPGP and S/MIME message formats to enable communications to recipients who use standard mail clients such as Outlook, Notes and Outlook Express. 

Ad Hoc Encryption – Encryption for everyone!

For recipients who do not use either PGP or S/MIME then the SECURE mail gateway can still send the message in a secure format using a password protected zip. This file can then be opened without needing any additional software and can also be opened when the recipient is not connected to the internet.

Content scan encrypted messages

With integrated encryption the Clearswift SECURE Email Gateway can decrypt encrypted messages by the comprehensive Anti-spam, Anti-virus and content filtering engines to ensure email adheres to the corporate email policy. Decryption can apply to both inbound and outbound messages providing correct key material.

Automatic Encryption / Signing

Messages can also be signed with a corporate signing key. This will ensure that recipients can be sure that messages arrive from your organization are valid, and they are not being subjected to a Phishing attack. 

Central Management

Certificate stores and policies can be replicated across Gateway nodes permitting high scalable solutions for encryption. The administration is centralized to make managing the Encryption features very easy. Granular access control Permits only the correct Systems Administrators to modify the encryption rules The intuitive, web based management interface combines ease of configuration and efficient management

No user training 

The encryption and signing of emails can be configured centrally without any interaction of the users. No certificates and no keys for users to worry about removes end user confusion.
