Description

This IDC PlanScape focuses on how to develop a third-party risk management program from a CISO perspective."Third-party products and services are not just 'nice to haves' but 'must-haves' in a modern business environment. Just think about the latest wave of AI. It would be practically impossible to move at speed without relying on at least some third parties. This introduces risk, which can be greatly reduced by making the right choices upon selection of third parties and in ongoing use of their products and services," says Nick Kirtley, adjunct research advisor, IT Executive Programs (IEP), IDC.
