Not a Bastion Host.
A Bastionne.
The word Bastionne comes from the French bastionné which means fortified with bastions. That’s exactly what we do: turn every device into its own autonomous stronghold.
No reliance. No assumed trust. No central points of failure.
Just sovereign, self-defending devices that forms the foundation of real zero-trust.
Every Device Becomes a Fortress.
Stronger security, easier implementation, and more efficient protection.

Real Security Starts at the Device.
Bastionne enforces access control directly on each device — no external brokers, no trust chains to intercept, no cloud to compromise. This hardened architecture blocks advanced threats like credential theft, CA compromise, and supply chain tampering — even when the network is under active attack.

Zero Cloud.
Zero Complexity.
Bastionne eliminates the need for complicated integrations and management. No wasted hours, no endless configurations, and no gaps from disjointed tools and systems. Just deploy, activate, and lock down your system in minutes.

Leaner, Faster, Future-Ready
Bastionne doesn’t just react—it prevents. Every data packet is encrypted with a unique key and assigned a new identity, making it immune to quantum decryption threats. All of this happens on the device, fully autonomously, meaning no latency, no gaps, and steadfast security even in constrained environments.
The Bastionne Armory
Solutions Powered by Our Technology
Ultra-secure access control and quantum-resistant data protection for military systems. Designed to keep critical systems intrinsically secure, resilient, and future-ready.
A stronger, simpler way to secure admin interfaces. Originally built for military operations, Custodes is now available to all—delivering enhanced protection for remote admin access without the complexity of VPNs, MFA, and IP whitelists.
Fortress-grade protection for legacy and modern OT environments—without sacrificing uptime, speed, or simplicity. Palisade defends critical systems in the harshest conditions with surgical access control and zero external dependencies.
Unlock a world of possibilities with the power of Bastionne. Our advanced security technology, now in API form, allows you to integrate, customize, and build your own fortress-grade solutions.
