About Us
About Private Garden
Private Garden is a small team building autonomous and independent, open-source-first solutions for organizations that want to own their stack end-to-end. Our work spans hardware-to-production security, independent CSPN and Common Criteria certification accompaniment, and upstream open-source contribution.
We believe technical mastery and independence are the foundations of durable security — not dependencies that disappear the day a vendor changes its mind.
Our Mission
Help organizations master every layer of their stack.
We do this through three levers: independent CSPN and Common Criteria certification accompaniment, help and counseling to setup sovereign open-source infrastructure, and transparent contribution to the open-source projects you depend on.
We refuse lock-in models: what we build with you must belong to you.
Our Approach
We work phase by phase, with a clear scope, complete documentation, and knowledge transfer at every step. No black boxes, no magic, no artificially created dependencies.
- Scope defined together before any technical action
- Rigorous documentation aligned with ANSSI frameworks for certification
- Reproducible, portable infrastructure
- Knowledge transfer so your team is autonomous by the end
