What is Content Disarm and Reconstruction (CDR) Technology?

Content Disarm and Reconstruction (CDR) is a proactive protection technology that removes executable content from files to prevent security threats. Unlike traditional security tools that rely on detection, CDR disarms all potentially dangerous elements in a document, ensuring safe file use. This method is known as threat extraction, providing reliable protection against both known and unknown threats.

How CDR/Threat Extraction Works

Content Disarm and Reconstruction (CDR) is a proactive document protection technology designed to neutralize threats without relying on traditional detection. Unlike conventional security solutions that scan for known malware signatures, CDR operates using a detection-free approach, disarming any executable content within files—whether it’s identified as malicious or not. This makes it a powerful tool for zero-day prevention, protecting against even unknown threats.

The process begins by analyzing the incoming document and identifying any embedded code, macros, scripts, or active content that could be exploited. These potentially harmful elements are removed, leaving only the core content of the document intact. The safe version is then reconstructed and delivered to the user, ensuring secure file access without compromising functionality. This approach allows organizations to maintain document security while avoiding the delays of traditional scanning methods, making it an ideal solution for high-security environments where speed and safety are critical.

Content Sanitization

Content Sanitization is a core feature of CDR technology, focusing on removing malicious code from files while maintaining their usability. During this process, the document is analyzed, and any executable elements—such as scripts, macros, or embedded objects—are extracted. The remaining safe content is then reconstructed to match the original document’s appearance and structure, ensuring it remains functional. This method offers a secure way to share and use files without risking exposure to hidden threats.

Conclusion

Content Disarm and Reconstruction (CDR) offers a proactive security solution that protects against document threats through safe delivery and zero-day protection, maintaining business continuity. Simultaneously, CDR as a file format in CorelDRAW is essential for designers and illustrators who rely on vector graphics for professional design work. This dual approach makes CDR a versatile technology for both digital security and creative design.
