As attack tactics escalate, your defenses must raise the bar on security, adaptability, and flexibility—and Owl data diodes are purpose-built to help you do exactly that. With Owl Talon v3.4.0.0, we show once again that we can keep you ahead of the adversary by bringing new OT/IIoT protocols online, sharpening day to day operations for IT/OT teams, and scaling highspeed one-way visibility for your most demanding environments. 

By upgrading to Owl Talon v3.4.0.0, you’ll access expanded protocol adapters enabling more options for secure one-way data paths, high-speed one-way performance scaled for modern OT loads, and operational enhancements that reduce friction for cyber operators—anchored by a roadmap built on extensibility, predictability, and long-term defensibility. 

Expanded OT and IIoT coverage with new adapters 

Talon 3.4.0.0 adds new protocol adapters and TLS authentication support, expanding options for secure OT, IIoT, and file-based transfers. 

• OPC UA is ideal for moving historian and SCADA data from PLCs and controllers into higher side analytics and monitoring tools. 
• MQTT is purpose built for streaming sensor and IIoT telemetry to brokers, cloud platforms, and SOC environments. 
• AVEVA PI High Availability support for Source and Destination OPTS PI server collectives lets utilities, energy producers, and industrial operators maintain resilient, redundant historian architectures without compromising the one-way security model data diode deployments demand. 

These capabilities let you move historian data, sensor telemetry, and bulk files through Owl Talon’s protocol filtering diode while preserving strong segmentation and one-way enforcement, and they integrate seamlessly with existing IT/OT architectures without sacrificing performance or security. 

Operational Enhancements to Keep IT/OT Teams Moving 

In addition to new Protocol Adapters, Owl Talon v3.4.0.0 delivers a slate of performance and security upgrades. Highlights include: 

• Email OAuth support alongside traditional authentication and NoAuth modes for legacy systems, helping DoD programs and commercial plants move toward stronger identity models without a full rip and replace, and aligning with cloud email platforms that have deprecated basic authentication. 
• TLS support on Syslog, RFTS, TCP, and MQTT, structured around clear source and destination roles—sources present a server certificate and private key, while destinations validate with CA certificates—making it easier for PKI and operations teams to split responsibilities and align with zero trust and cross domain requirements. 
• SFTP support in both Server and Client modes, giving network architects flexibility to place SFTP endpoints on whichever side of the boundary makes sense, reducing the need for extra gateways or custom scripts. 
• UDP performance improvements that further optimize Owl Talon for high volume, low latency traffic such as sensor streams, syslog bursts, and other real-time feeds common in OT and monitoring environments. 

Owl Talon v3.4.0.0 is the latest proof of Owl’s commitment to delivering stronger security and higher performance for the always on demands of modern IT/OT environments. 

High-Speed, High-Volume One-way Ops Boosted with Owl Talon Torrent 

As of v3.4.0.0, Owl Talon Torrent—our high speed, U.S. Government validated protocol filtering diode—now supports RFTS, SFTP, HSTCP, Syslog, UDP, and TCP, giving operators a broad protocol toolkit on a single high assurance platform. For organizations that need next generation, hardware enforced one-way transfer up to 100 Gbps, this expanded protocol support enables secure, high throughput telemetry and logging at scale while ensuring the diode keeps pace with your visibility and historian strategies instead of slowing them down. 

Keep Critical Ops Running: Upgrade Today, Stay Ahead Tomorrow 

Customers can move to Owl Talon v3.4.0.0 today, and if you need support, our team is ready to help.  

And in the meantime? We’re already back to work on the next wave of protocol, performance, remote access and security enhancements that keep pushing the platform forward. Upcoming releases will focus on making Owl Talon more extensible and adaptable, so you can adopt new capabilities on your schedule and align upgrades with your own roadmaps—without weakening Owl Talon’s one-way, protocol filtering security.  

Combined with improvements like enhanced access options, continuing vulnerability management, and regular security releases, Owl Talon is the definitive data diode platform you can confidently plan, operate, and grow with over time. You can learn more about what’s coming next from our Product Management team in our upcoming webinar.
