The CISO Guide to Third-Party Risk Management

In the past 12 months, 85% of organizations experienced at least one third-party incident, and nearly two in three had more than one. Boards, customers, and auditors keep asking the same plain question: how do you know your vendors are secure, and where is the proof? For most teams, the honest answer is that coverage is partial, evidence is scattered, and the newest risk—AI buried inside vendor products—is barely governed at all. This guide gives security leaders a working model for closing that gap.
