What is Metascan?

Metascan is a powerful and flexible solution for detecting and preventing known and unknown threats. ISVs, IT admins and malware researchers use Metascan to get easy access to multiple anti-malware engines at a single time, via a rich set of APIs.

This technology is available through Metascan Online via the web interface and API, as well as through an on-premises version of Metascan that can be deployed in your own environment and even offline, with additional features like document sanitization available.

Why Multi-scanning?

No single anti-malware engine is perfect 100% of the time. Using multiple engines to scan for threats allows you to take advantage of the strengths of each individual engine and to guarantee the earliest possible detection. OPSWAT's multi-scanning technology optimizes the included engines to enable fast, simultaneous scanning and eliminates the hassle of licensing multiple products.


How can I add my engine?

Metascan Online currently includes engines from Symantec, McAfee, ESET, Norman, AVG and many others. Anti-malware engine vendors who are interested in having their engine added to Metascan Online should visit www.opswat.com/partners/metascan-engine-suppliers for more information. All engines included in the program may enter the free malware sample sharing program, providing automated delivery of potential false positive and false negative samples. By visiting OPSWAT.com, vendors can also learn about having their engine included in our packaged Metascan solutions.
