Security
Your clients' books stay in their own systems. Qestra keeps the decisions, and seals them.
Qestra reads from your client’s system while it works. Workflows keep only ids, counts and hashes.
Accounting system keys are held by our integration partner. Qestra keeps only a reference.
Append-only and hash-chained, and checked every night. A changed entry breaks the chain.
Row-level security keeps every firm’s data apart in the database.
AI explains and classifies. Sums, matches and currency are calculated in code you can test.
Everyone signs in with a password and a code from an authenticator app, or with Microsoft.
Pick the model for each agent: hosted in the EU/EEA, or one your firm runs itself. Set a rule for the whole firm or per client, and no data leaves Europe.
Qestra is your data processor. We sign a data processing agreement with every customer.
