Vendor & Third-Party AI Risk Review
Model approval registry, prompt-injection detection, PII leak scanning — gating what data and models touch a workflow before they run.
"Every new model or vendor integration your teams adopt is a new surface for prompt injection, PII leakage, and silent model drift — and vendor risk assessments are stale the day they're signed off. Vouchstone puts a standing agent team on model and vendor risk instead of a point-in-time questionnaire."
What you are actually dealing with
- Vendor risk assessments are stale the day they are completed — no continuous monitoring
- Prompt injection, PII leakage, and model drift risks grow with every new AI deployment
- No central registry of which models are approved for which data classification
- Vendor questionnaires are a one-time PDF, not a living record that updates when the vendor changes
- New model rollouts ship without a gate checking what data they are allowed to see
How we ship it
- Model approval registry: every model mapped to the data classifications it is cleared to touch
- Continuous vendor risk agents re-check vendor posture on a schedule, not just at onboarding
- Prompt-injection detection agents scan inputs before they reach a model
- PII leak scanning (Presidio) gates outputs before they leave a workflow
- Data classification gating blocks a workflow from routing regulated data to an unapproved model
- Every gate decision signed to an immutable audit ledger — reviewable evidence, not a point-in-time PDF
What we owe you when we miss
Most SI contracts only penalise you for falling behind on payment. Our Reverse SLA flips that - when we miss a named milestone, parity threshold, or budget band, we owe you in credits or refund.
Coverage
Named vendors and models in scope for continuous monitoring, not a one-time review
Detection
Vendor risk and posture changes detected within 4 hours
Gating
Every model call checked against the approval registry before it runs — no silent exceptions
Vendor & Model Risk Registry
Model approval registry mapped to data classifications, continuous vendor risk dashboard, prompt-injection and PII-leak scan logs, and a signed audit trail of every gating decision.

Other flagship engagements
Internal Knowledge Copilots
Narrow, team-specific copilots grounded in tribal knowledge — not one generalist bot that knows a little about everything. Built on a living context graph of your docs, code, contracts, and conversations.
Legacy, ERP & Data-Warehouse Migration
Specialist agents grounded in a knowledge graph of source and target schemas do mapping, CDC pipeline building, and UDF conversion deterministically — COBOL, ASP.NET, Oracle, mainframes, and warehouses migrated with row-level parity proofs.
RPA Replacement in Finance Ops
AP invoice automation and cost anomaly detection. Every approval checked against exact graph facts — vendor, contract clause, policy — and written as a signed workflow trace, not a brittle screen-scraping bot.
