Abstract: Protocol Filtering Diodes—Securing Critical Infrastructure Beyond One-Way Data Flow
Critical infrastructure operators face relentless cyber threats and ever-tightening regulatory demands. Owl Cyber Defense’s Protocol Filtering Diodes (PFDs) deliver a new standard for secure data transfer—combining hardware-enforced, one-way communication with deep, FPGA-based protocol inspection.
Purpose-built for power, oil & gas, and nuclear environments, Owl’s PFDs empower organizations to:
- Safely share real-time operational data across network boundaries without exposing critical systems to inbound threats.
- Filter and validate every data packet at the hardware level, ensuring only authorized, compliant information leaves secure networks.
- Integrate multiple protocols and data flows—including SCADA, historian logs, and alarms—through a single, low-maintenance device.
- Achieve and maintain compliance with NERC CIP, IEC 62443, and other industry mandates, supported by a solution rigorously tested to U.S. Government standards.
- Scale securely for future needs, with expansion-ready architecture and minimal operational overhead.
Discover how next-generation PFDs are redefining what’s possible in industrial cybersecurity.
