“Assessment: One of the strongest options if your organization already uses Microsoft 365, Azure, and Entra ID.”
“Microsoft Entra Agent ID | Native | Yes | Yes | Yes”
“Microsoft Entra Agent ID | Native | Yes | Yes | Yes”

“Microsoft Entra Agent ID | Native | Yes | Yes | Yes”
“Entra maintains distinct agent identities in sign-in and audit logs.”
“Assessment: One of the strongest options if your organization already uses Microsoft 365, Azure, and Entra ID.”
“Assessment: Particularly interesting for enterprises with agents accessing multiple SaaS applications and MCP servers.”
“Okta for AI Agents | Native | Yes | Yes | Yes”
“Okta for AI Agents | Native | Yes | Yes | Yes”
“Okta for AI Agents | Native | Yes | Yes | Yes”
“Okta for AI Agents | Native | Yes | Yes | Yes”
“Okta's Agent Gateway acts as an identity-aware proxy between agents and enterprise tools.”
“Okta's System Log captures token grants and delegated token exchanges, helping establish who authorized an agent's access.”
“An important distinction: Okta's AI agent offering can also operate alongside other identity providers, so adopting it doesn't necessarily require replacing Entra ID.”
“Assessment: One of the most interesting architectures for cloud-native autonomous agents, particularly where cryptographic workload identity and strong identity separation are priorities.”
“Google Cloud Agent Identity | Native | Yes | Yes | Yes”
“Google Cloud Agent Identity | Native | Yes | Yes | Yes”
“Google Cloud Agent Identity | Native | Yes | Yes | Yes”
“Google Cloud Agent Identity | Native | Yes | Yes | Yes”
“A unique cryptographic identity.”
“Google Cloud Audit Logs can record agent identity operations.”
“Assessment: Particularly attractive for developers building AI agent platforms, SaaS applications, and systems requiring resource-level authorization.”
“Auth0 for AI Agents | Native | Yes | Yes | Yes”
“Auth0 for AI Agents | Native | Yes | Yes | Yes”
“Auth0 for AI Agents | Native | Yes | Yes | Yes”
“Auth0 for AI Agents | Native | Yes | Yes | Yes”
“This is significantly more expressive than conventional role-based access control (RBAC).”
“Auth0 also provides centralized authorization auditing, including permission changes and resource-access events.”
“Assessment: Excellent for agents operating predominantly within AWS. However, you will need to assemble more of the agent identity and governance architecture yourself.”
“AWS IAM | Workload identity / IAM roles | Yes | Yes, through federation and token delegation patterns | Yes, through CloudTrail”
“CloudTrail records API activity, including the identity and role associated with requests.”
“Temporary credentials can be issued through AWS STS.”
“However, you will need to assemble more of the agent identity and governance architecture yourself.”
“Assessment: Worth considering when the priority is enterprise-wide visibility, governance, access certification, and compliance rather than runtime authentication.”
“SailPoint | Agent identity governance | Governance and access reviews | Governance-focused | Yes, through connected systems”
“Assessment: Worth considering when the priority is enterprise-wide visibility, governance, access certification, and compliance rather than runtime authentication.”
“Its focus is less on issuing runtime tokens and more on governing the identities and permissions of agents across an enterprise.”
