OPSWAT sells to plant operators rather than households. Founded in 2002 by Benny Czarny, it built its business around a problem ordinary endpoint security does not address: files and removable media crossing into networks that cannot be patched, rebooted or taken offline — power, water, manufacturing, defence, air-gapped government systems — where the answer is to inspect and sanitise whatever crosses the boundary rather than to install an agent on the far side of it. Everything sits on the MetaDefender Platform. MetaDefender Core and MetaDefender ICAP Server scan files in transit using Metascan Multiscanning, which runs one file past many antivirus engines instead of trusting a single verdict, and Deep CDR, which rebuilds a document without its active content rather than judging whether that content is hostile. MetaDefender Kiosk scans removable media at a site entrance and MetaDefender Drive boots a machine to inspect it before it is admitted; MetaDefender Managed File Transfer carries what passes inward; MetaDefender Optical Diode and MetaDefender Unidirectional Security Gateway make a network link physically one-way. MetaDefender Network Access Control and MetaDefender Endpoint cover device posture. The company moved its headquarters to Tampa, Florida in 2023 and has grown partly by acquisition — Impulse (network access control, 2019), Fend (data diodes) and InQuest (file inspection and threat intelligence). OPSWAT also appears in this index as an assessor, not only as a vendor. The OPSWAT Certification column — Platinum down to Bronze — is its assessment of how well another company's antimalware product interoperates with the OESIS Framework, the component that access-control systems use to check what protection a device is running. A level shown in that column is OPSWAT's judgement of someone else's product, not of its own. Vendor page →
