OPSWAT Deep CDR™ Technology Achieves 100% Sanitization Rate in Independent AV-Comparatives Testing

AV-Comparatives recorded a 100% sanitization rate for OPSWAT's Deep CDR™ Technology across more than 300 test cases, the third independent lab to report a 100% protection result for the technology after SE Labs and SecureIQLab, OPSWAT announced on Sept. 9, 2026. The Austrian ISO 9001:2015-certified lab evaluated sanitization effectiveness by attack scenario, coverage across roughly 50 file types, and file fidelity after reconstruction, with the test set including AI-assisted malicious content, zero-day exploits, malicious macros, embedded executables and nested archives. "Our test is pass or fail. There is no partial credit," said Thomas Uhlemann, Cybersecurity Evangelist at AV-Comparatives.

TAMPA, Fla. – Sept. 9, 2026 – OPSWAT https://opswat.com/ , a global leader in critical infrastructure protection CIP cybersecurity solutions, today announced that testing lab AV-Comparatives recorded a 100% sanitization rate for Deep CDR™ Technology https://www.opswat.com/resources/reports/deep-cdr-independent-reports across 300-plus test cases. It is the third independent lab to record a 100% protection result for Deep CDR™ Technology, after SE Labs and SecureIQLab. Deep CDR™ Technology was also the first CDR Content Disarm and Reconstruction technology to record a 100% accuracy score in SE Labs testing. AV-Comparatives, an Austrian, ISO 9001:2015-certified testing lab, evaluated Deep CDR™ Technology on sanitization effectiveness by attack scenario, coverage across approximately 50 file types, and file fidelity after reconstruction. The test set included AI assisted malicious content, zero-day exploits, malicious macros, embedded executables, nested archives and other evasive file borne attacks. Deep CDR™ Technology passed every case under the tested configuration while preserving file usability. Macros, embedded executables, nested archives, AI-assisted payloads — 300-plus cases, and nothing came through Macros, embedded executables, nested archives, AI-assisted payloads — 300-plus cases, and nothing came through. Our test is pass or fail. There is no partial credit. Thomas UhlemannCybersecurity Evangelist, AV-Comparatives Attack campaigns evolve quickly, but the underlying exploitation techniques like malicious macros, embedded executables, steganography, and malformed archives remain attackers’ go-to choice. Deep CDR™ Technology takes a prevention-first approach to file security. It treats every file as untrusted, then disarms and rebuilds each file in milliseconds, removing embedded and out-of-policy content while preserving layout, formatting, tables, and formulas so the file stays usable. It supports 200+ file types across email, web, file-transfer, and endpoint workflows. Part of the MetaDefender® platform, it can be deployed on-premises, in the cloud, or air-gapped. At OPSWAT, we do not grade our own homework. Our commitment to CDR means repeatedly putting Deep CDR™ Technology in front of leading independent security testing organizations and asking them to stress test it against the newest file borne attack techniques, including threats created or adapted with AI. Three independent labs have now reported 100% protection results. That is the level of evidence critical infrastructure deserves. Detection must recognize a threat to stop it. Deep CDR™ Technology removes the risky content whether the threat is known, unknown or AI generated.
