What Is OPSWAT Multiscanning? How 30+ AV Engines Detect Over 99% of Threats

OPSWAT Metascan Multiscanning is an advanced threat detection technology that scans every file with 30+ anti-malware engines simultaneously. Rather than relying on a single antivirus engine, which typically catches between 40% and 80% of malware, Metascan Multiscanning combines signatures, heuristics, and machine learning from multiple vendors in a single parallel scan to achieve detection rates greater than 99%.

Each engine brings different detection capabilities and threat intelligence. When a new threat emerges, the first engine to release a signature catches it, providing the earliest possible protection. OPSWAT Metascan also includes AI-enhanced file type verification, which analyzes a file's internal structure to identify its true type regardless of the extension, and integrates the SentinelOne behavioral AI engine for protection against ransomware, fileless malware, and APTs.

Organizations can choose customizable engine packages from 4 to over 30 engines. All engines run under a single OPSWAT license, deployable on-premises, cloud, or air-gapped environments.
