File Upload Protection

Prevent Malicious File Uploads Through Web Applications

MetaDefender prevents malicious file uploads on web applications that are bypassing sandboxes and other advanced threat solutions. By integrating MetaDefender’s industry-leading multi-scanning, vulnerability assessment and data sanitization, also known as content disarm & reconstruction (CDR) technology, you can secure your web applications with the highest and earliest possible protection against known and unknown threats.

We evaluated sandboxes, AV vendors and cloud multi-scanning vendors for our zero-day malware file upload challenge and chose Data Sanitization from OPSWAT.

Block Malicious File Uploads

Maximize Threat Detection

Using a single antivirus engine to protect file uploads is simply not enough. MetaDefender's multi-scanning technology leverages over 30 leading anti-malware engines using signatures, heuristics, and machine learning technology to detect known as well as unknown threats, increasing detection rates of known threats to nearly 100%.

Neutralize File-borne Threats

MetaDefender’s industry-leading Data Sanitization (CDR) technology neutralizes unknown file-borne threats by sanitizing and rebuilding files ensuring full usability with safe content. In addition, MetaDefender detects vulnerabilities in uploaded software executables and performs recursive archive inspection to detect threats in compressed files and prevent archive bombs.

Deployment via REST API

Embed MetaDefender REST API calls directly into your web application, such as upload servers and managed file transfer solutions, for rapid threat detection and sterilization as files are transferred. The MetaDefender REST API interface is language-agnostic and accessible from virtually all web languages and websites. Use the MetaDefender API in your own environment, or use the MetaDefender Cloud API to harness OPSWAT’s fast cloud services.
