Attackers increasingly use obfuscation, mutation, and zero-day exploits to bypass traditional cyber defenses. MetaDefender Core v5.17.0 helps security teams stay ahead with AI-predictive threat detection, a refreshed user experience, and workflow improvements that make file analysis faster and clearer for daily operations. These upgrades strengthen advanced threat coverage and support efficient investigations and compliance.
Here’s what’s new:
OPSWAT Alin: AI-Predictive Threat Detection Engine
MetaDefender Core introduces OPSWAT Alin, an AI-predictive threat detection engine that works alongside Metascan™ Multiscanning to deliver deeper and more accurate threat detection. Powered by a domain-trained machine learning model, OPSWAT Alin analyzes file structures, entropy patterns, and semantic relationships to identify potentially harmful files earlier and with greater precision.

OPSWAT Alin is refined continuously with millions of clean and malicious samples and with real-world telemetry from MetaDefender Aether and OPSWAT Threat Intelligence. This delivers an additional detection method that does not rely on signatures or behavioral execution, and that provides a proactive signal when evaluating unknown files. The result is stronger coverage against emerging threats with fast performance that fits existing workflows.

Refreshed UI for Clarity and Speed
New Login Experience
Administrators will see a cleaner layout with updated visuals and a more streamlined flow that creates a smoother entry point into the product and sets the foundation for future usability improvements.

Redesigned Processing History
The Processing History view offers clearer visibility into file events, timestamps, outcomes, and processing steps. This helps teams understand what happened to each file and speeds up investigations while supporting validation for auditing and compliance.
Clearer Scan result
The updated interface delivers a detailed breakdown of each engine's verdict, including reasons and severity. It also provides improved navigation for nested archives. Users can see which engines detected which indicators and understand why a file received its final verdict, so triage becomes faster.

Stronger Archive Handling for Real World Workflows
Split Archive Support
MetaDefender Core now combines part files automatically, extracts their contents, and scans all child files so teams can submit an archive in parts through the API without manual recombination. This simplifies automation and strengthens coverage for a format frequently abused by attackers who rely on archive-based delivery methods such as archive file concatenation.

Extraction Failed Filter
A new filter highlights archives that could not be extracted during processing. This helps administrators quickly identify potential corruption, legacy compression approaches, or evasion attempts that require follow-up.

Operational Enhancements
Support Package Export for Secure Troubleshooting
Organizations with strict confidentiality or regulatory requirements can export a support package and share log information with OPSWAT Support in a controlled and privacy-conscious way. This enables faster issue resolution while preserving data governance.

Email Notifications for Malicious Batch Results
Alerts for malicious detections are consolidated into a single summary email which reduces inbox noise and prevents large automated workflows from overwhelming administrators, so focus stays on critical issues.

License Support for NIC Teaming
Environments that use Network Interface Card teaming on Windows Server benefit from improved stability because MetaDefender Core no longer requires license reactivation when interfaces change or fail over. This reduces administrative effort in high availability network architectures.
Additional Certificate Upload Option
Administrators can upload certificates directly from a folder which adds flexibility to certificate management and simplifies workflows that depend on predefined directories or automated delivery.
