We are excited to announce the release of MetaDefender OT Access 2.0.0 that brings significant upgrades in hardware, operating system, and integration capabilities to better meet the needs of modern OT environments.
Whether you're managing critical infrastructure or industrial operations, this release offers improved performance, heightened security, and smarter workflows for secure file transfer into isolated OT networks.
New High-Performance 1U Hardware
The latest version ships with a brand-new 1U appliance, equipped with a faster CPU and upgraded hardware architecture.
This means:
- Faster processing and lower latency
- Improved throughput for large file transfers
- Enhanced reliability for 24/7 industrial use
The 1U form factor also ensures space efficiency in control rooms and industrial cabinets without compromising power.
OS Upgrade to Debian 12: Performance and Security Boost
MetaDefender OT Access v2.0.0 now runs on Debian 12, bringing a host of improvements:
- Better hardware support and real-time performance
- Stronger security posture with hardened system libraries and protocol support
- Long-term stability and updates from the Debian community
This OS upgrade not only future-proofs your OT environment but also reduces risks by aligning with modern cybersecurity standards.
Integration with MetaDefender Core for Secure File Transfer
Industrial environments frequently face the challenge of transferring files such as patches, firmware updates, engineering documentation, or configuration files from IT networks or external sources into secured OT networks. Without proper controls, these transfers can expose critical infrastructure to malware, ransomware, or compliance violations.
With MetaDefender OT Access v2.0.0, we address this challenge head-on by introducing deep integration with MetaDefender Core via secure API calls, designed specifically to:
- Sanitize files before they enter OT networks
- Ensure administrative oversight with file approval workflows
- Provide real-time system health visibility
How the Integration Works
1. File Submission
A user submits a file for transfer into the OT environment using MetaDefender OT Access.
2. Automated File Scanning and Sanitization
MetaDefender OT Access communicates with MetaDefender Core through secure APIs to perform:
- Multiscanning using multiple antivirus engines to detect known threats
- Deep CDR to remove hidden threats or embedded code
- File type verification to prevent disguised file types from entering the network
3. Approval Workflow
Before the file is released into the OT network, a built-in approval process ensures that a designated Admin or Super Admin reviews and authorizes the transfer. This reduces insider risks and enforces governance policies.
4. Health Status Monitoring
The integrated system provides visibility into the operational health and connectivity status of the OT Access appliance, ensuring that decisions are made based on trusted system states.
Why MetaDefender OT Access v2.0.0 Stands Out
MetaDefender OT Access v2.0.0 provides a comprehensive advancement in how industrial organizations manage and secure file access into critical OT and CPS (cyber-physical systems) networks.
With a new 1U performance appliance, customers benefit from faster processing, greater reliability, and space-efficient deployment options tailored to industrial rack environments.
The upgrade to Debian 12 delivers a major leap in performance, system stability, and security, thanks to a modern Linux kernel and enhanced system libraries. This makes MetaDefender OT Access more resilient, future-ready, and aligned with current cybersecurity best practices.
Most critically, the new integration with MetaDefender Core introduces a secure and policy-driven method for transferring files into isolated OT networks. By combining advanced threat prevention technologies such as Multiscanning and Deer CDR with enforced admin approval workflows and real-time health monitoring, organizations can:
- Minimize the risk of malware, ransomware, and unauthorized content entering the OT environment.
- Establish clear governance, traceability, and compliance over every file movement.
- Eliminate manual, insecure file transfer methods (e.g., uncontrolled USB use or unvetted emails).
- Strengthen their zero-trust security posture while maintaining operational agility.
Together, these enhancements make MetaDefender OT Access v2.0.0 a trusted gateway for secure, controlled, and efficient remote access and file transfer in critical infrastructure environments.
