Questions about our licensing?

Here are the most frequently asked questions

OPSWAT has explicit agreements for redistributing the scanning results only with all the vendors in the commercial offering.
If you have a commercial license your file will be deleted after scanning when using private scanning at upload time. All other files can be kept by OPSWAT and, if infected, shared as part of malware sharing programs. For more details see our Privacy Policy.
No, all static operations performed when a file is uploaded, including Deep CDR are charged as one request.
Hash lookup requests that return not found requests are charged with a ration of 5:1 For each 5 hash lookups not found, we charge 1 request.
All hashes come from files that OPSWAT has scanned in time from various sources in including malware sharing programs, users, and integrations with other OPSWAT products.
