OPSWAT, founded in 2002 by Benny Czarny, is a San Francisco-based software company that provides software engineers and information technology workers with security software development tools and services.



OPSWAT provides a security software interoperability certification program for application types, including:

Although the program shares the idea of software certification with testing agencies like ICSA Labs, West Coast Labs, Virus Bulletin and AV-Comparatives, unlike those agencies it does not certify applications for their efficacy, but rather for their level of interoperability and manageability with third-party technology. The program, therefore, is not in competition with anti-malware testing companies and has, in fact, formed partnerships with several of them.[1][2]

As of March 2011 membership consisted of more than 45 application vendors including AT&T, AVG Technologies,[3] Avira,[4] Check Point, ESET,[5] Kaspersky Lab,[6] Kingsoft,[7] Panda Software and Verizon.[8]


OPSWAT Endpoint Security Integration SDK (OESIS) is a software framework, middleware and software development kit (SDK) that provides third party software engineers with an interface to manage third party software vendors.[9][10][11]

As of April 2010 over 50 different OEMs are licensed OESIS, including Cisco Systems, Citrix NetScaler, F5 Networks and Juniper Networks.[12][13]


Metascan combines multiple antivirus engines into a single application (Computer Associates, Norman ASA, ESET, VirusBuster, AVG Technologies, Quick Heal Technologies, Sunbelt Software, and ClamWin).[14] It is also available as a core package that is used to manage a users own anti-malware applications.[15] A primary use case is as antivirus server software, particularly as ASP antivirus.

AppRemover is a software utility and SDK for uninstallation of security applications like McAfee and Symantec antivirus and antispyware products.[16][17] AppRemover has three interfaces: free, a commercially brandable GUI, and an SDK for managers and software engineers. The SDK comes as a command line interface or application programming interface (API).

Secure RAM Disk is RAM disk software.


Because the OESIS Framework can detect hundreds of antivirus applications, OPSWAT is able to analyze market share data based around actual installations. The company issued an antivirus market share report in 2010.[18][19]
