Build on Sertainty

Sertainty UXP technology lets a file enforce its own access rules. Protect the file inside a Vault and the protection travels with it, whether it sits on a laptop, a USB stick, a cloud bucket or a recipient's machine.

UXP is the Sertainty technology, the engine that does the protecting. A Vault is what it creates.

Current release Q4 of 2026. Three kits ship as separately packaged products, each on its own version schedule. Sertainty Developer V5.1.0, Sertainty TechHub V1.0.0 and Sertainty Server V1.0.0. v5 function calls match earlier releases, and existing applications compile and run without code changes. A v5 license is required. Release notes

Kits

Three kits, installed independently

Each kit targets one audience. Install what the deployment needs. The Core UXP framework is fully standalone, and servers are only needed when you opt into the Services layer.
