Clearswift Secure Exchange Gateway

Apply data loss prevention policies to your internal email communications. The Clearswift Secure Exchange Gateway ensures that internal email correspondence on your Exchange 2010, 2013 or 2016 deployments matches the confidentiality and compliance policies of your organization. Messages that contain certain violations can be quarantined for manual inspection, or the offending content can be removed through the use of Adaptive Redaction. With critical information protection starting within the organization, malicious and or accidental data leakage is further mitigated.

ARgon for Email

Adaptive security add-on for existing gateways. ARgon can be used in environments with no DLP solution or to augment an existing one. In both cases, ARgon removes next generation information threats from both inbound and outbound email. For those with an existing DLP solution, ARgon reduces the false positives by automatically removing the content which would cause the DLP solution to ‘stop & block’ the communication.

Email Encryption

With TLS as standard, and cost options to provide either S/MIME, PGP and password protected files or Web portal-based encryption, the Email Gateway offers a variety of options to cater for customer requirements. Whichever you choose, the Gateway allows sensitive data to be delivered securely, in seconds, using the optimal format for the recipient.

Adaptive Redaction

Adaptive security is automatically applied in real-time based on specific regulatory or governance policy, whether it calls for redaction, encryption, blocking, moving or deleting. Clearswift's unique Adaptive Redaction technology removes the compliance burden on organizations by removing only the non-compliant information from being shared, allowing the rest of the information to continue without disruption and false positives. Compliance protection that goes unnoticed from the end user.
