AI third-party risk matrix
Most organisations have far more AI in their stack than they realise — the official API, the note-taker plugged into meetings, the AI feature buried inside a SaaS tool a team turned on last month. Each one is a third party that can see your data, and each is a potential leak path. This matrix turns that sprawl into a scored inventory so you can govern it deliberately instead of discovering it during an incident.
How it works
You add each AI provider, API, or embedded feature and classify three things: the most sensitive data it can reach, how long it retains inputs, and whether you have a signed data processing agreement. The tool combines those into a risk score — sensitivity plus retention, with an extra penalty when personal data flows to a vendor with no DPA — and assigns each row a LOW, MEDIUM, or HIGH band. The portfolio summary surfaces your single highest exposure so you know where to start.
Tips and notes
- Hunt for shadow AI first. The riskiest tools are usually the ones nobody formally approved — browser extensions, free transcription apps, AI features toggled on inside existing software.
- Retention is the cheapest lever. Switching a provider to zero retention or opting out of training on your data often drops a row from HIGH to LOW with no loss of function.
- Re-score after every contract change. A renewed DPA or a provider policy update can move a tool between bands — keep the matrix current rather than treating it as a one-off audit.
