Clearswift Secure Exchange Gateway: Overview


Clearswift Secure Exchange Gateway (SXG) helps to safeguard against critical information being distributed through internal email and subsequently leaving an organization.  Detecting malware, suspicious scripts, and identifying sensitive data in messages and attachments based on an easily defined policy-based rules enables organizations to adhere to security and compliance requirements.

Messages that contain critical data or inappropriate content can be quarantined for manual inspection, or the offending content can be removed through adaptive redaction technology. With critical information protection starting within the organization, malicious and or accidental data leakage is further mitigated.

SXG ensures that internal email correspondence on your Exchange 2010, 2013 or 2016 deployments matches the confidentiality and compliance policies of your organization.

Key Benefits of Secure Exchange Gateway

Deep content filtering of the message and its attachments can ensure that inappropriate content or critical information can be detected. With support for over 150 file formats and character set recognition for over 200 languages, objectionable or sensitive content can be detected using keyword search utilizing standard and easily customized dictionaries.

With a choice of Sophos or Kaspersky, messages can be scanned by up to two engines, without incurring any additional processing cycles on the Exchange server. Structural validation checks can be applied on file formats to detect whether data has been pre-pended or appended to a file to evade detection. Remove active code from PDF, word documents and HTML to reduce the chance of advanced persistent threats like malware from infiltrating in the corporate messaging service.

Rules can be easily defined to cover internal and Internet based email with the use of AD/LDAP integration. Enhance your security by customizing per individuals or organizational units. This is important when organizations have to ring fence departments; for example, in banks, military and research, or simply when a multi-national company has particular export controls that they have to adhere to.

Monitor Mode enables you to test your DLP policy without impacting your message flow. Copies of messages are processed by the SXG platform. The results are used to identify if and where you have issues with email content or whether your DLP policy needs adjusting to prevent false positives.

Unlike most other Exchange scanning products, the Secure Exchange Gateway offers an off-box solution designed to reduce the load on your Exchange servers ensuring that message delivery times are not compromised.

SXG can be integrated with existing Secure Email Gateways (SEG) and Secure Web Gateways (SWG) to share policies and reporting data. When the SXG is used in conjunction with SEG, the System administrator can manage the messaging policies from a single dashboard for both boundary and internal email.
