Assess the risk a vendor poses

Vendors with access to your data extend your risk to them, and assessing that risk is essential. This tool assesses vendor risk based on the data they access and its type, so you can prioritise which vendors need scrutiny.

Why vendor risk scales with data access

A vendor is a risk to the extent that a breach of them would expose your data, so the risk depends on what data they can access and how sensitive it is. A vendor touching only public information is low risk; one handling your customers’ personal or financial data is high, because their compromise becomes your breach. Assessing vendors on this basis focuses scrutiny where it matters, since you cannot deeply vet every vendor equally. This is a core part of managing third-party risk, one of the most common ways organisations are breached.
