Secure IT/OT. Always-On Ops. Owl Data Diodes
Owl data diodes, including protocol filtering diodes, go beyond firewalls with hardware-enforced one-way data transfer that secures IT/OT links, reduces cyber risk, and keeps critical operations online. They enable safe replication of historians and business systems, trusted sharing of production and sensor data, and continuous cyber monitoring without exposing control networks to inbound threats.
Defense-Grade One-Way Protection for Critical Infrastructure.
Programs that still rely on brittle outbound firewalls or basic, opaque diodes to move OT data off sensitive networks introduce unnecessary operational risk. Owl Protocol Filtering Diodes combine hardware‑enforced one‑way transfer with FPGA‑based protocol filtering, backed by a leadership position proven in the world’s most demanding government environments and now securing commercial critical infrastructure. This one‑way protection lets critical infrastructure operators securely connect IT and OT, maintain continuous operations, and meet stringent regulatory requirements without increasing cyber risk.
Flexible, High-Speed OT Transfer up to 100 Gbps
Scale from remote sites to enterprise backbones with flexible form factors and support for multiple simultaneous protocols on a single appliance, all without disrupting existing architectures.
Mission-Tested, Nuclear-Grade Defense-in-Depth Security for OT
Leverage the same high-assurance one-way protections used in defense, nuclear, and other high-consequence OT environments to deliver true defense in depth while maintaining OT visibility.
Certified, Always-On Assurance and Compliance
Common Criteria EAL4+ evaluated and Protocol Filtering Diode–validated designs, with redundant options for high availability, support rigorous regulatory, audit, and internal compliance requirements.
Owl Talon Data Diode Products
Owl Talon One™
Owl Talon One features a single PCIe‑based protocol filtering diode that delivers up to 1 Gbps of hardware‑enforced one‑way transfer with FPGA‑based protocol filtering and multiple simultaneous protocols in a single appliance. Ideal for critical infrastructure operators who need high‑assurance, low‑latency one‑way paths between OT and IT, Owl Talon One reduces SWaP and rack space so you can standardize on one platform for all one‑way needs.
Discover owl talon one Owl Talon Torrent™
Realize next‑gen high speed with ultra‑low latency using Owl Talon Torrent. This PFD platform scales to 100 Gbps, combining FPGA‑based protocol filtering with hardware‑enforced one‑way transfer so backbone links can move OT and analytics data to IT, SOC, and cloud—without ever exposing industrial control networks to remote access.

Product UpdatesAs operations evolve, Owl data diodes adapt with you.
Owl data diodes, including protocol filtering diodes, give critical infrastructure operators a simple way to cut IT-to-OT attack paths while keeping visibility, analytics, and reporting online. By enforcing true one-way flow at the hardware level, they reduce cyber risk, support compliance, and help protect uptime across nuclear, oil & gas, water, and other high‑consequence environments.
- Data diodes and PFDs move high‑value data out of protected or contested networks—like HTNs—while preserving one‑way separation and continuous visibility for mission threads.
- Data diodes eliminate IT-to-OT attack paths by enforcing true one-way data flow, so operators can safely replicate historians, stream sensor and process data, and feed SOC or cloud analytics from OT. This lets critical infrastructure organizations reduce cyber risk, prevent remote access into control networks, and maintain visibility and uptime without relying on brittle outbound firewalls or complex segmentation.

The Ultimate Value Guide to Owl Talon
In high-stakes government and mission-critical environments, secure, real-time data transfer is essential. As cyber threats grow more sophisticated, traditional methods leave critical systems exposed. Owl Talon™ addresses this risk with hardware-enforced data diode technology that delivers ultra-secure, uninterrupted one-way data flow—protecting data integrity, strengthening security, and supporting confident decision-making where it matters most.
Pick the Right “One‑Way” Before an Adversary Proves You Didn’t
Owl protocol filtering diodes give you a more defensible “one‑way” foundation for high‑assurance and RTB‑style environments than firewalls or basic diodes. Before you lock in your next architecture, see exactly where Owl leads on assurance, performance, and control—and how that compares to firewalls posing as “unidirectional” and other diode vendors.
