Email Gateway

SECURE Email Gateway

Built on MIMEsweeper, Clearswift's celebrated content-inspection and filtering technology, the Clearswift SECURE Email Gateway is a highly effective and resilient email gateway for 50 to 50,000 users. With the Clearswift SECURE Email Gateway installed, your organisation can be confident that it is protected from digital threats and data leaks while employees communicate freely by email.

Reliable, resilient, responsive

The Clearswift SECURE Email Gateway's powerful content-inspection engine is twinned with an easy-to-use policy centre to assist with development of effective email-use policies. Ready-made template policies ensure that the Clearswift SECURE Email Gateway is fit to perform from the moment it is deployed.

Creating new policies, or modifying policy templates, is a quick and straightforward process. The rules can be tailored at user level to better manage how email messages are shared, stored and distributed. To ensure consistency and save time on administration, policies are linked to directory servers and update transparently across multiple and SECURE Email Gateway installations.

Email Encryption

The Clearswift SECURE Email Gateway can also be used to send and receive encrypted email in a number of different industry standard formats:

S/MIME, PGP and also using an ad-hoc method of password protection (including AES).
Web Portal (pull, push)
Flexible policies for email encryption permit messages to be encrypted by direction or by content. Depending on which technology and deployment is used encrypted messages can be decrypted and then passed to the content inspection engine to ensure no information is leaking out inadvertently.

Content inspection and malware protection

The Clearswift SECURE Email Gateway is equipped with the most capable content-hygiene tools. Bidirectional anti-virus and anti-malware protection is built in. This means both inbound and outgoing emails are checked for viruses and other malware.

The content of both message bodies and attachments are scanned. Deep scanning of message attachments means that the content of compressed files is examined, too. File identification is based on binary signatures, rather than file names, improving accuracy and ensuring that unrecognised file types are picked up. Images can be checked for pornographic content as well as the ability to register corporate images as either acceptable or unacceptable for email distribution.

To prevent data leaks and damage to reputation, the Clearswift SECURE Email Gateway checks message content for compliance with your organisation's policies. This is supported by managed lists and editable terms and compliance dictionaries. These include payment card industry (PCI) patterns, personally identifiable information (PII), Gramm-Leach-Bliley Act (GLBA), Health Insurance Portability and Accountability Act (HIPAA), Securities and Equities Commission (SEC) and the Sarbanes-Oxley Act (SOX).

Unify your organisation's internet security by deploying both Clearswift SECURE Web Gateway and SECURE Email Gateway and benefit from considerable administrative savings, thanks to these common content-inspection technologies.

Smart Clearswift technologies

The Clearswift SECURE Email Gateway includes several unique Clearswift technologies to fend off spam, ensure content cleanliness and to keep messages moving freely.

Clearswift TRUSTmanager, a technology that checks sender reputations against a constantly updated database provided by Clearswift removes 80% of spam before it reaches the gateway saving significant bandwidth.

Clearswift SpamLogic a real-time spam-detection technology then identifies and filters spam with an accuracy of 99.5%. It does this by examining the message source, content and destination, as well scanning attachments.

Default policies will filter and quarantine messages from senders with bad or suspicious reputations without impeding emails from those with neutral or good reputations. Users can be sent scheduled summary messages, enabling them to review and, if appropriate, release filtered messages from the web portal. This ability to delegate spam identification to users reduces administration and improves productivity. As a further aid to efficiency, users can manage their own sender whitelists.

Protection against malware is provided by the integrated Kaspersky Anti-virus engine, a Zero hour anti-malware filter, Active Content Detection methodsand backed by Clearswift's ThreatLab Live technology, designed to keep watch for new malware threats.

These are all accessed from the same, simple web-based interface. Pre-defined reports are easily modified and can be executed across multiple Clearswift SECURE Email Gateways for a consolidated view of user activity.
