Identity Management (IdM) focuses on who users are, handling user registration, authentication, and identity data. Access Management (AM) determines what authenticated users can do, managing authorisation, permissions, and access control. Together they form IAM (Identity and Access Management).
Cloud-based solutions like Okta and Microsoft Entra ID offer faster deployment, scalability, and lower infrastructure costs. On-premises solutions provide more control and suit organisations with strict data residency requirements. Hybrid deployments blend both approaches for legacy and modern systems.
Pricing varies by model: user-based (£2-10/user/month), capacity-based (thousands/month), or enterprise custom deals. Auth0 and JumpCloud offer transparent per-user pricing, whilst Okta and CyberArk typically require custom negotiations based on scale and requirements.
