Military-Grade Cybersecurity for Critical Infrastructure
BIG9000 — Rugged, FPGA-based unidirectional gateway engineered to guarantee one-way data flow with zero risk of remote infection. Designed for industrial, defense and critical systems (-40°C to +70°C).
GrowTrade Corporation are strategic partners of BlackBear CyberSecurity. BIG9000 is a military-grade, rugged, fanless unidirectional gateway purpose-built to protect Industrial Automation Control Systems (IACS) and OT networks by enforcing one-way data flow. It is certified to EN61000-6-2, EN61000-6-4, IEC/EN/UL 62368-1:2014 and FCC, and operates in extreme environments from -40°C to +70°C.
Data Diode — One-Way Hardware Enforced
FPGA-controlled, non-reversible data flow. Prevents inbound malware, ransomware and remote command injection.
Last-Mile Security & Encryption
Supports VPN / MACsec, hardware-accelerated crypto and secure packaging for field deployments.
Wire-Speed Packet Validation
Deep packet validation and protocol conformance checks at line rate — no bypass, no backdoor.
Reverse Diode (Optional)
Validated command injection in one direction only — reconstructs safe outbound commands without returning state or files.
“No door, no vulnerability”
A Unidirectional Gateway (data diode) is a hardware device placed between two networks of different security levels that only permits information to move in one direction. By using physical layer-1 isolation, BIG9000 ensures that data can flow out of an untrusted zone but there is no physical return path, making remote infection of OT systems impossible.
