ReSec Technologies
ReSec Technologies was an Israeli cybersecurity startup specializing in content disarm and reconstruction (CDR) technology that prevents file-borne threats by deconstructing incoming files and rebuilding them as clean, threat-free versions—eliminating malware, zero-day exploits, and embedded malicious content.
Visit WebsiteCompany Overview
ReSec Technologies developed a content disarm and reconstruction (CDR) platform that prevented file-borne cyberattacks by intercepting incoming files (email attachments, web downloads, file transfers), deconstructing them to their fundamental components, removing any potentially malicious elements, and reconstructing clean, fully functional versions of the original files. Unlike detection-based approaches that rely on signatures or behavioral analysis, CDR assumes all files may be malicious and sanitizes them—providing zero-trust file security that is effective against zero-day exploits and unknown threats.
Commercially, ReSec competed in the CDR and advanced threat prevention market alongside Votiro, OPSWAT, Sasa Software, and Glasswall. Founded in 2014 in Ra'anana, Israel, the company was backed by OurCrowd and other investors. In 2022, Fortra (formerly HelpSystems) acquired ReSec Technologies, integrating its CDR capabilities into Fortra's cybersecurity portfolio alongside Clearswift (email security), Digital Guardian (data protection), and other security products.
From a defense and national security perspective, CDR is directly relevant to protecting military networks from file-borne threats in cross-domain transfer scenarios, email systems, and intelligence sharing environments. The ability to sanitize files without relying on threat detection enables secure file transfer between classification domains and protects defense networks from weaponized documents—a primary attack vector in targeted military operations.
Dual-Use Assessment
Content disarm and reconstruction is critical for military cross-domain file transfer, protecting defense email from weaponized documents, and sanitizing intelligence-sharing files. Zero-trust file security eliminates reliance on detection that misses zero-day threats.
Key Technologies
- Content disarm and reconstruction (CDR) engine
- File deconstruction and clean reconstruction
- Zero-trust file sanitization (assumes all files malicious)
- Multi-format file handling (Office, PDF, images, archives)
- Email attachment and web download sanitization
- API-based CDR integration for file transfer workflows
Use Cases & Applications
- Enterprise email attachment sanitization
- Web download threat prevention via file reconstruction
- File transfer security for shared collaboration environments
- Zero-day exploit prevention through proactive file sanitization
- Military cross-domain file transfer security (dual-use)
- Defense email protection against weaponized document attacks (dual-use)
Strategic Value to U.S.-Israel Alliance
CDR is essential for military cross-domain transfer and protecting defense networks from weaponized files. Zero-trust file sanitization eliminates the detection gap that signature and behavioral approaches cannot close.
