Calm, precise security for European companies.
Trustefi helps engineering teams, manufacturers and regulated companies trust what their systems depend on.
Why we exist
Modern software is built from thousands of parts made by others. Every package, certificate and secret is a promise of trust. We make sure those promises hold, quietly and automatically.
The name: Trust plus EFI
Trustefi combines trust with EFI, short for Enterprise Forensics & Intelligence. Forensics means every decision leaves evidence you can inspect later. Intelligence means analysis that spots risk before it becomes an incident. Together they describe how we work: trust that is earned, recorded and automated.
Forensics
Every inspection, block and approval is logged, so you can always show what happened and why.
Intelligence
AI-assisted analysis that recognises risky packages, weak keys and unsafe AI use early.
What guides us

Security that watches constantly without creating noise or fear.
