TL;DR: Hardware-based RADIUS creates cost, maintenance, and scaling problems for Wi-Fi and VPN authentication, while cloud delivery centralizes policy and removes on-premises infrastructure burden according to JumpCloud. For IAM and NHI teams, the real shift is from appliance management to identity-backed network access governance.
NHIMG editorial — based on content published by JumpCloud: RADIUS in the cloud for secure network access
Questions worth separating out
Q: How should teams govern Wi-Fi and VPN access when RADIUS moves to the cloud?
A: Treat cloud RADIUS as part of the identity control plane, not a separate network utility.
Q: When does hardware-based RADIUS become a governance liability?
A: It becomes a liability when authentication, failover, and scaling depend on a single appliance tier that cannot keep pace with distributed work.
Q: What do security teams get wrong about cloud network authentication?
A: They often assume moving RADIUS to the cloud is only a hosting change.
Practitioner guidance
- Audit RADIUS as an identity dependency Inventory every Wi-Fi and VPN path that relies on RADIUS, including failover, certificate issuance, and directory lookup dependencies.
- Replace shared network secrets with unique identity-bound access Use per-user and per-device credentials so access can be revoked without changing a shared secret across the estate.
- Test authentication resilience before migration Validate how the access layer behaves during identity-provider outages, certificate expiry, and site connectivity loss.

Cloud RADIUS and network access control: what changes for IAM teams?

Cloud RADIUS is really an identity governance problem, not a network hardware problem. The article frames the move away from appliances as an operational simplification, but the deeper change is that network access becomes another policy-driven identity surface. That matters because authentication quality, access visibility, and lifecycle control now sit closer to IAM than to infrastructure maintenance. Practitioners should treat RADIUS as part of the access governance stack, not a standalone network utility.
A few things that frame the scale:
- 67% of organisations still rely heavily on static credentials despite the risks they pose to agentic AI deployments, according to the 2026 Infrastructure Identity Survey.
- That same survey found that only 44% of organisations have implemented any policies to manage their AI agents, even though 92% agree governance is critical to enterprise security.
A question worth separating out:
Q: How do IAM teams reduce risk when replacing on-premises RADIUS hardware?
A: Use the migration to enforce unique credentials, remove shared secrets, and connect network access to the same joiner, mover, and leaver controls used elsewhere in IAM. That creates clearer accountability and makes revocation much easier to operate.
