Identity and Access Management (IAM) Services – Provider Compendium 2025

The rapid digitalization of enterprises and the convergence of IT and OT environments have transformed identity into the cornerstone of cybersecurity and digital trust. With the expansion of cloud, IoT, and hybrid work models, organizations face growing challenges in governing a mix of human and non-human identities, managing privileged access, and ensuring compliance in an AI-driven world. Emerging risks such as voice impersonation and deepfake-based credential abuse are pushing IAM beyond traditional access controls toward proactive identity security and resilience.

Providers are responding with automation-led IAM frameworks, AI-driven provisioning and certification workflows, identity threat detection and response capabilities, and identity security posture management solutions. They are also integrating password-less authentication, bring your own identity (BYOI), and unified identity fabrics that enable seamless governance of users and AI agents alike. Additionally, partnerships and accelerators are helping enterprises address skill shortages, accelerate time-to-value, and ensure compliance across complex multi-cloud ecosystems.

This compendium offers Everest Group’s perspective on 20 leading IAM providers, based on detailed primary research, RFIs, client interactions, and continuous market assessment. It provides actionable insights into their service portfolios, investments, delivery presence, and differentiators in enabling secure, agile, and scalable IAM transformation.
