**Trustworthy by design**

This is less a promise about how the model behaves than a constraint on what it is allowed to hand you.

The Workbench is where your team works. The Harness is the part underneath that nobody should have to think about, standing between the agents and anything that leaves the building. Trusting a model to be right is a strategy that holds until the one time it does not, and here that one time is a rate filing, a reserve opinion, or a number somebody testified to.

**Built for enterprise security**

Controls are built into the system so that AI can finally be used without keeping anyone up at night.

**FAQ**

**Frequently asked questions**

Common questions from chief actuaries, pricing teams, and the IT and risk officers who review us alongside them.

## Bring us your hardest actuarial question

A tangled web of formulas, a stale memo, a rater your team can't get off Excel. Make it hard for us, and let us show you the breadth of the Workbench.

**Single-tenant**

A bespoke environment your IT team controls, on infrastructure shared with nobody.

**Zero data retention**

Your data is never used to train a model, ours or anyone else's.

**SOC 2 + SOX ready**

Three environments, separated roles, full audit trail on every promotion.

**ASOP-aligned**

Trained on the CAS syllabus and ASOPs 23, 41, and 56. The standards your reviewer is held to.

**Actuarial Review**

AI that understands and audits your work, and catches issues before external review.

**Pricing**

GLM-driven pricing end to end: train, prepare filings, and anticipate objections, with every figure cited to its source.

**Reserving & Close**

Reserving with instant anomaly detection, then the close on the same data spine: roll-forward, reconciliation, commentary, and sign-off tracking.

**Board-Ready Reporting**

Instant, drillable answers and consolidated reporting for committees and regulators.

**Rater Deployment**

Turn an approved rater into a live, callable service with custom interfaces, at scale.

**Universal Data Ingestion**

Any carrier format in, one clean schema out: ingestion, mapping, and validation on entry.

**a month, back**

Per actuary, measured on our own workflows.

**the output per actuary**

Same headcount, same standards, twice the work through the door.

**traceable to source**

Every value Tesora populates cites the cell or page it came from.

**Can we import our existing rating models?**

Yes. Upload your Excel raters directly and the system rebuilds, tests, and deploys them for you, parsing the formulas and identifying the factor tables to produce a versioned model that preserves your existing logic exactly.

**What integrations do you support?**

Snowflake, Databricks, Guidewire, and Okta are supported out of the box, along with AWS, Microsoft Excel, and Microsoft 365. REST API for anything else. If you use it, we can connect to it.

**How does role separation work for SOX?**

Three environments: dev (actuaries build), test (QA validates), prod (underwriters use). Different roles have different access. Actuaries cannot push directly to prod. Full audit trail of who promoted what and when.

**Do you train on our data?**

No. Zero data retention policies are in place with our model providers. Your data is not used for model training, ours or anyone else's.

**Is confidential data protected?**

Yes. Each customer is deployed as a single-tenant, bespoke environment your IT team controls. Your data does not share infrastructure with any other customer.

**Ingestion Agent**

SERFF filings, Excel, SQL, R, Python, cited to source.

**Pricing Agent**

Trending, on-leveling, GLMs, severity fits.

**Rating Agent**

Raters, factor tables, callable pricing API.

**Reserving Agent**

Loss development, chain ladder, tail factors, IBNR.
