Security
Built for the people
who can’t afford a leak.
Advisory and legal work runs on client trust. azta is engineered so that trusting it is a rational decision — verifiable output, isolated data, certified controls.
Certified & compliant
Certified, audited,
and inspectable.
SOC 2 Type II
Independently audited controls, continuously monitored.
ISO 27001
Certified information-security management system.
GDPR
European data-protection law, by design.
EU data residency
Your data stays in the EU/EEA. Always.
Sealed tenant
Enterprise isolation — never co-mingled.
Data sovereignty
Your data is yours.
Never trained on
Your questions, files and knowledge never enter model training — on any plan.
Never visible to others
Tenant isolation is enforced at the database layer — one tenant can never read another's chats, files or knowledge.
Never outside the EU
Data is stored and processed in the EU/EEA. Residency isn't a plan feature — it's the architecture.
Traceability
Every answer,
traceable to its source.
azta doesn’t ask you to trust the model. Every claim in every answer links to the paragraph, act or directive that produced it — so you verify the source, not the AI. The audit trail shows the full reasoning path.

The mechanism
How azta avoids wrong answers.
azta’s research is built and verified by practising tax advisors, lawyers and engineers — people who carry professional liability themselves and decide what “right” looks like.
- 01Grounded in the actual lawAnswers are built from a structured corpus of European legislation, directives, treaties and official guidance — not from a model’s memory.
- 02Cited at paragraph levelEvery claim carries its source. If a claim can’t be traced to a provision, it doesn’t ship as an answer.
- 03Current by designNew legislation is tracked and indexed daily, so answers rest on today’s rules — not last year’s.
- 04Verified by practitionersPractising advisors and lawyers continuously test and correct the system’s output quality.
- 98.7% of answers source-traceable — the practitioner benchmark, run continuously.
§ 05 — Enterprise
Enterprise isolation.
Enterprise deployments run in sealed tenants — your documents, your questions and your knowledge space are isolated from every other customer, behind your SSO, under your governance.
