OPSWAT announces proprietary AI-based threat detection engine for MetaDefender Platform

OPSWAT has announced OPSWAT Predictive Alin AI, its first proprietary AI-based threat detection engine for the MetaDefender Platform.  

This AI-based innovation introduces a new category of capability within the MetaDefender Platform, a high-confidence predictive layer that works alongside existing detection and prevention engines to assess malicious intent before execution, driving greater efficiency across the platform. This enables organisations to act immediately, while minimising the operational impacts of false positives.

“At OPSWAT, we’ve always believed that security begins with prevention, and the assumption that every file is malicious. The Predictive Alin AI Engine wasn’t built to replace your security team; it was built to make them more effective and efficient,” said Benny Czarny, Founder and CEO of OPSWAT. “By delivering machine-learning verdicts in milliseconds — before execution, before detonation — we cut through the noise and eliminate the hesitation that costs organisations the most. Our AI-native capabilities give security teams the trust and clarity they need to act with confidence, turning smarter detection into stronger decisions at the speed enterprises demand.”

Precision-first AI built for real-world operations

OPSWAT Predictive Alin AI is a machine learning-based static analysis engine that evaluates file structure, entropy patterns, and semantic relationships to predict whether a file will behave in a malicious way, without solely relying on signatures or runtime execution. It delivers sub-100-millisecond inference for most files, operates with a small memory footprint, and performs identically in online and offline deployments.

In an internal efficacy analysis, OPSWAT evaluated Predictive Alin AI, demonstrating:

• 99.99% precision in identifying safe files, validated across months of production traffic testing to minimise noise and false positives. When uncertain, the MetaDefender Platform triggers additional workflows and data handling for further assessment of data, automatically reinforcing the defence-in-depth concept.
• A measurable uplift in overall efficiency when added to multiengine deployments.

The results confirm that Predictive Alin AI currently performs best as a decision confidence layer within a multi-engine architecture, particularly in environments where false positives can disrupt operations, block critical workflows, or trigger costly response actions.

“Raw detection rate is not the same as operational value,” said Yiyi Miao, Chief Product Officer at OPSWAT. “Predictive Alin AI was engineered and evaluated with precision as the primary objective. When it fires, customers can have a high degree of confidence in that verdict, which is exactly what many enterprise environments need.”

Availability and platform integration

Predictive Alin AI adds a proprietary predictive capability alongside MetaDefender’s existing Metascan Multiscanning, Deep CDR, and adaptive sandbox technologies. It is fully developed in-house by OPSWAT’s data science and R&D teams and trained on curated, privacy-safe datasets from MetaDefender Aether telemetry, OPSWAT Threat Intelligence, and Unit 515 research. The model is continuously refined using correlated feedback across OPSWAT’s ecosystem.

The engine is already deployed in customer environments worldwide and is particularly relevant for defence, government, manufacturing, and energy sectors operating under strict regulatory and connectivity constraints. Predictive Alin AI is available today via MetaDefender Core for Windows and Linux as well as MetaDefender Cloud.
