Hardware-Enforced. Protocol-Aware. Owl Data Diodes

Owl data diodes, including Protocol Filtering Diodes, are purpose-built and U.S. Government validated for high-assurance defense and intel missions that require assured one-way transfer for mission data, ISR and sensor feeds, command-and-control information, and cyber monitoring telemetry.

High-Assurance, Protocol-Aware One-Way Transfer up to 100 Gbps.

Programs that still rely on brittle outbound firewalls or basic, opaque diodes to move mission and OT data off sensitive networks are introducing unnecessary mission risk. Owl PFDs combine hardware‑enforced one‑way transfer with FPGA‑based protocol filtering, so only well‑formed, policy‑approved data crosses the boundary—delivering deterministic behavior and evidence aligned with high‑assurance and Raise the Bar (RTB)‑style expectations.

Flexible Deployment from Edge to Enterprise

Embed Owl PFDs in platforms and weapons systems, deploy them at base and lab boundaries, or weave them into enterprise fabrics feeding cyber defense, analytics, and mission systems for resilient, end‑to‑end data assurance.

Up to 100 Gbps of One‑Way Assurance

Feed big data and AI without giving up one‑way security. Owl protocol filtering diodes deliver protocol‑aware, one‑way protection up to 100 Gbps with flexible appliance and card options, so you can adapt to changing missions without changing your assurance model.

High‑assurance and U.S.‑Government Evaluated

Owl PFDs have undergone rigorous U.S. Government PFD evaluation process and are foundational elements for high‑assurance architectures, adhering to Raise the Bar and Zero Trust guidance and giving programs stronger evidence for compliance and high‑consequence mission reviews.

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 defense programs that need high‑assurance, low‑latency one‑way paths between classified and enterprise domains, Owl Talon One reduces SWaP and rack space so you can standardize on one platform for all one‑way needs.

One-Way Mission Security: FAQs

When mission needs change, your one‑way security doesn’t have to.

Owl PFDs cover a wide range of use cases—from ISR and cyber telemetry to plant historians and OT logs—adapting as missions evolve while preserving the same trusted, one‑way, protocol‑aware protection your teams already rely on.

  • Data diodes and firewalls protect networks differently. A data diode is a hardware‑enforced one‑way device; protocol‑filtering diodes add mission‑specific control on top of that physical separation.
  • Firewalls filter two‑way traffic with software rules and patches, leaving gaps for misconfiguration and zero‑days. Protocol‑filtering diodes enforce strict, protocol‑aware one‑way flows for mission‑tailored protection.

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.

Secure, One-Way Data Flow Starts Here

Our experts have seen nearly every mission, plant, and platform scenario—and built Owl’s flexible protocol‑filtering diode options to match. Bring us your architecture, constraints, and “what ifs,” and we’ll help you adapt fast with proven designs that keep you ahead of threats. Ready to talk?
