OPSWAT MetaDefender Core: A Central Security Service Against File-Borne Threats
2 November 2026


OPSWAT MetaDefender Core is an advanced file threat prevention platform that analyses files with technologies such as multiple antimalware engines, Deep CDR, sandboxing, file type verification and sensitive data checks. It is embedded via API or ready integrations into web uploads, file transfers, business applications and security gateways, so files are checked before they reach the target system.
Core Capabilities
Multiscanning: Not relying on a single detection engine increases the chance of catching known and new malicious files.
Deep CDR: Risky active elements are removed and the usable content of the file is rebuilt, so workflows need not be blocked entirely.
File type and data checks: Files whose content does not match their extension, and content carrying sensitive data, are caught.
Benefits for Organisations
The organisation standardises controls by using a common file security service across applications, avoids separate development costs for each one, and manages its file-borne attack surface centrally.
