Performance Report - Multi-Scanning and Data Sanitization

Disclaimer: These results should be viewed as guidelines and not performance guarantees, since there are many variables that affect performance (file set, network configurations, hardware characteristics, etc.). If throughput is important to your implementation, OPSWAT recommends site-specific benchmarking before implementing a production solution.

  • M8: Metadefender 8 (Ahnlab, Avira, BitDefender, ClamAV, ESET, Quick Heal, Total Defense, Vir.IT eXplorer )

  • M12: Metadefender 12 (M8 + F-Prot, nProtect, Ikarus, K7)

  • M20: Metadefender 20 (M12 + Kaspersky, Emsisoft, Zillya! , McAfee, Sophos, Antiy, NanoAV)

  • DS: Data Sanitization number is additional time elapsed comparing to scanning speed without Data Sanitization enabled. For this testing, same file type sanitization is used. E.g., PDF to PDF.

  • † faster speed for bigger file size is mainly due to amount of components that need to be sanitized rather than file size for office document.
