The Boundary Problem No Diode Can Solve Alone
Every day, defense and government teams move files across security boundaries, including email, patches, imagery, and code. A hardware diode enforces one-way transfer, but it cannot see what’s inside those files. That blind spot creates several risks:
Advanced Threats Bypass Single-Engine Scanning
A single antivirus engine catches only 40–80% of malware on average. Zero-day exploits, polymorphic malware, and evasive file-borne threats often slip through signature-only scanning.
Accreditation Drains Engineering Time
Programs must satisfy cross-domain patterns, NATO NIAPC expectations, and authority-specific ATO requirements. Building evidence packages by hand is slow, error-prone, and pulls engineers away from mission work.
Vendor Lock-In Blocks Flexibility
Single-vendor stacks tie you to one hardware platform. When coalition partnerships shift or procurement cycles change, you face costly rip-and-replace or gaps in content security.
Manual Review Slows the Mission
Without automated policy enforcement, the boundary becomes a bottleneck. Analysts wait for file-release decisions while mission-critical data sits in a queue.
Unvetted Software Reaches the High Side
Patches, third-party code, and container images cross to classified networks without vulnerability, SBOM, or integrity checks. The diode alone cannot address supply-chain risk.
Content-Centric Security for Every Boundary
OPSWAT adds a vendor-agnostic content-security layer on each side of any certified diode. It verifies, sanitizes, governs, and documents every transfer, so the mission keeps moving and the audit trail writes itself.
Stop Advanced Threats at the Boundary
Metascan™ Multiscanning with 30+ antivirus engines up to 99.2% detection. Deep CDR™ Technology strips all active content from 200+ file types and rebuilds clean, usable files. Adaptive Sandbox adds up to 99.9% zero-day detection when paired with OPSWAT Reputation Service.
Protect Your Existing Infrastructure
Pair MetaDefender solutions with existing diode vendors or deploy on OPSWAT’s own Optical Diode family. Same content security engine, any transport.
Replace Manual Bottlenecks with Automation
Granular allow/deny rules, DLP redaction, watermarking, and workflow gating enforce release criteria automatically. Manual reviews become the exception, not the rule.
Secure the Software Supply Chain at the Boundary
SBOM/SCA validation, vulnerability assessment, and signature/checksum verification for patches, containers, and third-party code are all enforced before the diode with full chain of custody from low to high side.
Secure Every Transfer

Imagery, Streams & Export Control
Format allowlisting, Metascan Multiscanning, Deep CDR™ Technology, and Proactive DLP™ technologies for export control before the diode. Re-scanning with provenance tagging and controlled release after crossing.
Every Message Clean. Every Crossing Logged.
OPSWAT applies Metascan Multiscanning, true file type verification, Deep CDR™ Technology with archive recursion, and Proactive DLP before the diode. Partner documents and attached files are sanitized by the same pipeline. Re-scan and deterministic release decisions with full audit logs after the diode.
Kiosk Ingest at the Classified Boundary
MetaDefender Kiosk™ provides the physical scanning station at facility entry points. Automated Metascan Multiscanning with up to 30+ engines, Deep CDR™ Technology, and Proactive DLP run on every file. Nothing enters the network uninspected. Chain-of-custody logging captures every submission, scan result, and release decision.
Develop Low, Deploy High
SCA/SBOM checks on builds and dependencies, File-Based Vulnerability Assessment on packages, Metascan Multiscanning, Deep CDR™ Technology for documentation, and DLP enforcement, all before one-way promotion. The same pipeline governs OS patches, AV definitions, and third-party libraries crossing to classified update servers. A policy gate and attestation log on the high side completes the chain.
Securing Defense Installations & Critical Infrastructure
MetaDefender Optical Diode™ and NetWall™ enforce hardware-level unidirectional transfer from OT/SCADA networks across defense installations. Sensor telemetry, historian replication, and monitoring data flow one-way to IT. File-based crossings (including firmware updates, OT patches, and configuration files) pass MetaDefender Core™ inspection via MetaDefender Diode X before reaching the operational network.
