Why File Type Detection Matters

Attackers disguise files to bypass defenses. Traditional verification misses these threats, leaving organizations exposed.

Spoofed File Types

Attackers disguise files to bypass defenses. Traditional verification misses these threats, leaving organizations exposed.

Missed Threats

Verification alone can miss hidden executables or embedded scripts, leaving security teams blind to dangerous payloads.

Inefficient Workflows

False positives and incomplete classification slow down scanning, overwhelm analysts, and increase operational costs.

How OPSWAT Stops File Spoofing

AI-enhanced detection analyzes structure and content to identify a file’s true type, closing gaps left by traditional verification.

Content-Aware Detection

Goes beyond extensions to inspect structure and bytes, ensuring accurate classification.

AI-Enhanced Accuracy

Machine learning reduces false positives and improves detection of edge-case files attackers often disguise.

Seamless Enforcement

Deploys inline at upload, email, or transfer points without slowing
user workflows.

Core Benefits

True File Type Detection

Prevent spoofed, mislabeled, or embedded threats from slipping through by identifying a file’s true format—not just its extension.

Reduced False Positives

AI-enhanced accuracy minimizes unnecessary quarantines, improving efficiency for SOC teams and downstream security tools.

Compliance Support

Enforce policies with confidence, ensuring only approved file types enter regulated environments and meet audit requirements.

How File Type Detection Works

A multi-layered engine combines AI with proven parsing and signature checks to deliver precise true type results.

Smart Pre-Checks

Smart Pre-Checks

Cross-checks extensions and MIME headers to quickly flag mismatches before deeper inspection.

Parser & Signature Analysis

Parser & Signature Analysis

Validates structure with format-aware parsers and byte-level signatures against known file types.

AI-Enhanced Classification
