TL;DR: Google Cloud Identity-Aware Proxy centralizes access for GCP resources and HTTPS apps, but StrongDM’s comparison shows it can be a poor fit for multi-cloud infrastructure, SSH, RDP, databases, and Kubernetes because it needs extra configuration, has limited third-party integration, and does not protect activity within a project. For IAM teams, the issue is not access centralization alone but whether the control plane can govern credentials, sessions, and auditability across mixed environments.

Editorial analysis by NHI Mgmt Group, based on content published by StrongDM: “Alternatives to Google Cloud Identity-Aware Proxy (IAP)”.

Key questions

Q: What breaks when access centralisation does not cover every protocol and cloud?

A: The control breaks at the boundary between authenticated entry and governed activity.

Q: Why do multi-cloud environments expose weaknesses in centralised access controls?

A: Because multi-cloud environments multiply the places where identity, policy, and logs can diverge.

Q: How can security teams tell whether an access platform is actually reducing risk?

A: Measure whether access requests, role changes, and offboarding events complete across all connected systems without manual cleanup.

Practitioner guidance

  • Define the governed access surface List every resource class that must be controlled through one policy model, including databases, servers, Kubernetes, SSH, RDP, and HTTPS applications.
  • Test post-authentication visibility Verify that the platform records commands, queries, and administrative actions after login, not just successful authentication events.
  • Align offboarding to actual resource access Make sure disabling the upstream identity or SSO session actually revokes access to every governed resource class, including third-party and cross-cloud targets.

Bottom line: The core issue is not whether access can be centralised, but whether the control plane still governs credentials, sessions, and evidence after access is granted.

Access centralisation is not the same thing as identity governance. Strong authentication at the edge does not automatically produce consistent control over credentials, sessions, and audit trails once access crosses protocols or clouds. The stronger the environment mix, the more obvious it becomes that entry control and governance control are different disciplines. Practitioners should stop treating a single access proxy as a complete governance model.

A question worth separating out:

Q: What is the difference between authentication protocol choice and access governance?

A: Authentication protocol choice determines how identity is verified, but access governance determines whether that identity should keep access over time. SAML and LDAP both authenticate, yet neither automatically enforces rotation, review, ownership, or offboarding. Practitioners need both protocol fit and governance controls to manage NHIs safely.
