Customer identity and access management (CIAM) is a high-priority imperative in the age of the customer (AoC). If your customers can't register or log into your website, mobile app, or phone system, or if they can't conduct low- and high-risk transactions easily, your customers and prospects will defect to competitors. The CIAM Security Maturity Model helps security and risk (S&R) pros evaluate CIAM processes to identify gaps they can address to realize the appropriate balance between security and usability. This is an update of a previously published report; Forrester reviews and updates it periodically for continued relevance and accuracy.
