Fortra Clearswift Secure Email Gateway

Fortra Clearswift Secure Email Gateway (SEG) is an enterprise email security and content inspection platform engineered to safeguard corporate messaging infrastructure against advanced phishing campaigns, targeted ransomware payloads, business email compromise (BEC), and unauthorized sensitive data exfiltration. Featuring proprietary Deep Content Inspection (DCI) technology, Clearswift SEG disassembles incoming and outgoing email messages and nested attachments down to their fundamental components to neutralize threats and sanitize sensitive information without disrupting legitimate message delivery.

The platform provides multi-layered inbound threat detection alongside granular outbound data loss prevention. Key capabilities include Adaptive Data Loss Prevention (A-DLP) that automatically redacts sensitive data from documents in transit, structural document sanitization that strips hidden tracking metadata and macros, anti-spoofing enforcement using DMARC, DKIM, and SPF, multi-engine spam and antivirus scanning, and automated optical character recognition (OCR) to detect confidential text embedded in images. By sanitizing content rather than blocking full documents, Clearswift enables uninterrupted business communications while maintaining stringent compliance standards.

Clearswift Secure Email Gateway integrates with Microsoft 365, Microsoft Exchange, Google Workspace, and leading enterprise SIEM platforms such as Splunk and IBM QRadar. Primary enterprise use cases include protecting organizations against spear phishing and weaponized attachments, preventing confidential data breaches via email, stripping risky metadata from outbound correspondence, and enforcing strict regulatory controls for defense and financial sectors. Fortra Clearswift SEG delivers precision threat defense and adaptive content governance.
