I’ve watched IAM evolve from simple LDAP directories to distributed identity meshes spanning cloud, on-prem, and edge. After implementing IAM for 50+ enterprises over 15 years, I’ve seen firsthand how the shift to remote work, cloud-native architectures, and zero-trust models has fundamentally changed identity security. What worked in 2015—VPN access with basic MFA—is a compliance failure in 2025.
