An audit agent you can trust with the evidence.
Tessero is built for regulated environments. Every engagement is isolated, each conclusion is traceable to its evidence, and the auditor always has the last word.
Cloud-first, on-prem when you need it
Tessero is hosted in our managed cloud by default, with every tenant isolated from the next. For data-residency or air-gapped engagements, deploy on-prem or in your private cloud and bring your own model — cloud or fully local — so evidence never leaves your boundary.
Object-level authorization
Every workspace request is authorized against membership, not just login. Engagements are sealed from one another so a user can only ever reach the evidence and findings they belong to.
Evidence is the source of truth
Original documents are retained and re-openable from any citation. The agent never fabricates or substitutes — a conclusion it can’t trace to a real document is not allowed to pass.
Reviewer in the loop
The agent proposes; the auditor disposes. Accept, override, or send a finding back — every action is captured in an append-only audit trail, with a senior-reviewer pass flagging anything not yet defensible.
Tested for isolation
Cross-workspace access is verified shut: no reading, downloading, or evaluating another tenant’s data by guessing an id or swapping a header.
Read-only by default
Where Tessero connects to systems to gather evidence, it uses read-only, least-privilege access — and never executes anything without your say-so.
