The Clearswift SECURE Exchange Gateway (SXG) helps to safeguard against inappropriate or critical information being distributed internally and subsequently leaving an organization. Underpinning both policy and compliance requirements, the Clearswift SXG detects malware and inappropriate file types and identifies violations in conversations based on an easily defined policy based rules.
Messages that contain certain violations can be quarantined for manual inspection, or the offending content can be removed through the use of Adaptive Data Redaction. Using keyword search of PDF and Office attachments it is now possible to dynamically replace keywords and phrases with an alternative character such as asterisks, meaning that any sensitive phrase is removed and no longer a threat. Along with keyword search; file size, true file type controls and filename blocking can be employed to detect or remove files that may not be business-related or simply over-sized that can have an effect on the Exchange infrastructure.
