Modern enterprises aren’t just adding employees; they’re adding subsidiaries, multiple teams, contractors, AI builders, temporary projects, and new SaaS tools every week.And every new addition to a company’s ecosystem also brings more credentials to manage.

Many of them might be stored in shared spreadsheets, developer environments, browser sessions, and automa

Agentic AI is changing how work gets done inside organizations. It’s embedded in IDEs and automation tools, and it’s showing up in browsers, internal workflows, and everyday productivity apps. Developers are using AI agents to accelerate engineering work, while knowledge workers are vibe coding apps without training on developer security practices, all of which create untenable risks for organizations. That shift has real implications for identity and access control. For years, identity security

Automating user provisioning sounds simple, until you remember everything that provisioning really touches.For most SaaS products, SCIM is “just” user and group lifecycle management. Your identity provider calls an API, accounts get created, access is assigned, and offboarding removes it.
