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.
