MetaDefender Core

Advanced Threat Prevention Development Platform

MetaDefender Core allows you to integrate advanced malware protection and detection into your IT solutions and applications, for instance to secure web portals from file upload attacks, enhance cybersecurity products, and develop malware analysis systems.

Using our REST API, you can easily leverage MetaDefender’s high-speed multiscanning, deep content disarm and reconstruction (Deep CDR), and file-based vulnerability assessment technologies, preventing zero-day attacks and unknown threats as well as providing close to 100% known threat detection, without affecting performance. MetaDefender Core also includes proactive data loss prevention (Proactive DLP) capabilities to detect and block sensitive content in files.


Prevent File-borne Threats

Use MetaDefender Core to enhance the security of your application or solution by leveraging MetaDefender’s advanced threat detection and prevention. MetaDefender’s Deep Content Disarm and Reconstruction (Deep CDR) technology prevents unknown file-borne threats by sanitizing and reconstructing files ensuring that any possible embedded threats are neutralized while maintaining full usability with safe content.

Maximize Threat Detection

MetaDefender’s multiscanning technology leverages 35+ anti-malware engines and significantly improves detection of known and unknown threats and provides the earliest protection against malware outbreaks. In addition, MetaDefender’s file-based vulnerability assessment technology can detect vulnerabilities in installers, binary files and Internet of Things (IoT) firmware before they are executed on endpoints.

Protect PII

MetaDefender proactive data loss prevention (Proactive DLP) can help companies prevent PII from leaving or entering the company’s systems by content-checking files before they are transferred. MetaDefender can search over 30 file types for sensitive content, including Microsoft Office, PDF, CSV, HTML and image files.

High Performance

MetaDefender Core offers fast scanning without affecting performance and is scalable to any volume with MetaDefender's built-in high-performance architecture and load balancing feature.

Easy Deployment via REST API

Embed MetaDefender REST API calls directly into your application. The MetaDefender REST API interface is language-agnostic and accessible from virtually all web languages and websites. We provide sample code and detailed API documentation to help you bootstrap your integration. Use the MetaDefender Core in your own environment or use the MetaDefender Cloud API to harness OPSWAT’s fast cloud services.
