In Forrester's 17-criteria evaluation of B2E cloud identity and access management (IAM) vendors, we identified the nine most significant SaaS providers in the category — Bitium, Centrify, IBM, Microsoft, Okta, OneLogin, Ping Identity, SailPoint, and Salesforce — and researched, analyzed, and scored them. This report details our findings about how well each vendor fulfills our criteria and where they stand in relation to each other to help security and risk (S&R) professionals select the right partner for their B2E cloud IAM, also known as identity-as-a-service (IDaaS), needs.
