Built for the Airgap
Enterprise software licensing that works where your software works: disconnected, secure, and auditable.
Why Licenz exists
Software vendors deploying to air-gapped environments have been stuck with two options: legacy licensing systems designed in the 1990s, or building something custom from scratch.
Legacy vendors like Thales Sentinel and Wibu CodeMeter require hardware dongles, kernel drivers, and massive installation packages. They were designed for a different era, when shipping physical media was normal and security audits were less rigorous.
We built Licenz to give enterprise software vendors a modern alternative: cryptographically secure licensing that works completely offline, with an open source client that security teams can audit before deploying to sensitive environments.
The problems we solve
Lost keys, shipping delays, USB port conflicts, physical inventory
Kernel drivers, system services, massive installation footprint
Obfuscated binaries that security teams cannot audit
"Contact sales" for quotes, per-dongle costs, annual minimums
Open source where it matters
The code that runs in your air-gapped environment should be fully auditable
// licenz-client - MIT Licensed
//
// Permission is hereby granted, free of charge,
// to any person obtaining a copy of this software
// and associated documentation files...
//
// THE SOFTWARE IS PROVIDED "AS IS", WITHOUT
// WARRANTY OF ANY KIND...
pub fn verify_license(
license: &License,
public_key: &PublicKey,
) -> Result<Claims, VerifyError> {
// Every line of this function is auditable
// No obfuscation, no hidden network calls
// Your security team can inspect everything
}Transparency builds trust
When you deploy software to an air-gapped network, you need to know exactly what that software does. Our client library is MIT-licensed and open source, because trust in security-critical environments must be earned through transparency.
- Full source code on GitHub
Read every line before deploying
- Build from source
Compile your own binary for maximum assurance
- No hidden network calls
Zero telemetry, zero phone-home in the client
Built for enterprise requirements
Security, compliance, and reliability for organizations that cannot compromise
Security-First Design
Modern cryptography with RSA-SHA256, Ed25519, and AES-256-GCM. Pluggable architecture for post-quantum readiness.
Compliance Ready
SOC 2 path, HIPAA-compatible, FedRAMP alignment. Full audit logging and data sovereignty options.
Self-Hosted Option
Run the license server in your own infrastructure for complete control. No data leaves your network.
Enterprise Support
Dedicated support channels, SLA guarantees, and direct access to engineering for critical issues.
Long-Term Stability
Stable APIs, semantic versioning, and long deprecation cycles. Your integration will not break unexpectedly.
Transparent Pricing
Public pricing on our website. No surprise fees, no per-dongle costs, no sales call required to get started.
Our approach to licensing
Simple principles that guide everything we build
Airgap-first, not airgap-compatible
We did not bolt offline support onto an online system. Licenz was designed from day one to work in completely disconnected environments. Every feature, every workflow, every edge case considers the airgap scenario first.
Security through transparency
Obfuscation is not security. Our client library is open source because we believe the best way to prove security is to let experts examine the code. Security teams in government, healthcare, and defense can audit every line before deployment.
Simplicity is a feature
A 2MB static binary. No JVM, no .NET runtime, no kernel drivers. Integration in minutes, not weeks. Complexity is often a sign of poor design, and in security-critical systems, complexity is risk.
