High-Assurance Foundations: From CRA to VS-NfD
The Cyber Resilience Act (CRA) and VS-NfD (German Government Restricted) requirements cannot be retrofitted. If your OS foundation isn’t “born” compliant, your certification process will stall.
We offer long-term support for NixOS 26.05 and custom features, so you can focus on delivering value.
Enterprise-grade stability, security and support so your systems stay reliable for years to come
Stable release branch with long-term maintenance and backports.
Direct access to engineers who understand your stack and your environment.
Continuous vulnerability monitoring and update guidance to reduce risk.

Leverage our expertise in shipping the Cyberus Hypervisor to build systems capable of handling restricted data.
Let us handle your Software Bill of Materials (SBOM) and vulnerability tracking, making you "audit-ready" with every build.
Our security tracker (ext.) monitors your specific dependency tree, alerting you to risks before they impact your regulatory standing.
Protect your market access with a platform designed to meet EU sovereignty standards and governmental security mandates.
The Problem: Standard NixOS moves fast. Every six months, your team is forced to pay an "upgrade tax"—diverting weeks of engineering talent away from product features just to keep the OS layer functional and secure.
Build on a professional-grade base that stays consistent throughout your entire product lifecycle, from R&D to long-term field deployment.
Remove the maintenance burden of the 6-month release cycle, allowing your engineers to focus on your value proposition.


Receive critical CVE fixes and kernel updates tailored to your stable environment.
Ensure the configurations you write today remain deployable for years, exactly as intended.
Relying on community forums or a single "Nix Expert" creates a business-critical bottleneck. When the platform breaks, your development stops.
Move beyond best-effort community support with a direct line to the engineers who maintain the CTRL-OS distribution.
Transfer the burden of OS-level troubleshooting to a commercial partner, ensuring your project’s momentum is never tied to a single individual’s availability.
Provide your management with the certainty of guaranteed response times for critical platform issues and security vulnerabilities.
We focus on the health and performance of the OS layer so your team can focus on the application layer with absolute confidence.
We provide long-term NixOS support with fast, reliable binary caches and immediate CVE fixes. Our experts offer extended professional assistance, test integration on demand, and seamless turn-key migration. This ensures security, stability, and flexibility tailored to your needs.
We offer at least 5 years of support for the NixOS 26.05. Choose from the release-small or an extended set of packages.
Get help when things get tough. Our experts are here to help, when you need it.
Our binaries are served from an exclusive and fast cache, independent of upstream.
Security fixes are back-ported and served via our caches in hours, not days.
Need better integration testing for a package? Submit your test cases to us and we'll run them as part of our CI.
Change the channel (or flake input), point your binary cache to us and that's it!
Through reproducible build, validated test results and a traceable system state
Declarative environments, versioning, rollback, and consistent builds
Automated pipelines triggered on every change with integrated system-level validation
Execution of tests on real devices with scalable and parallel validation.
Maintain secure, stable systems with controlled updates and long-term operability.
