Trust and security

Proof you can check.

For privacy, compliance and governance teams: what the engine will not do, how each decision is checked, and what its output is ready for.

Try it: the note on the right hides a relative’s name in plain prose. Compare pattern-based masking with Tidegate.

Compliance stance

Ready for your expert, not a substitute for one.

WHAT THE OUTPUT IS READY FORHIPAA Expert DeterminationProtected output is prepared for expert determination: every protection is logged with its evidence, and a re-identification risk summary, measured on the output, ships with every release.
WHAT WE DO NOT CLAIMThe determination is yoursTidegate does not perform expert determinations or certify compliance. Your qualified expert reviews the output and makes the determination. If you need an expert, we introduce you to independent, qualified experts.
Every decision explained

The life of one decision, on the record.

Each step records who or what acted, the evidence, and the versions in force. Merges can be reversed, and the reversal is recorded too.

What we report, in the order we report it.

Every result is tested against records labeled by trained reviewers, every release. A missed identifier is treated as a safety event.
