Policy-Driven VLAN Assignment

Automated Network Segmentation with Cloud RADIUS

Segment users and devices automatically during RADIUS authentication. Cloud RADIUS uses real-time identity and device assessment to assign VLANs based on role, compliance status, or risk profile so you can quarantine at-risk devices and reduce lateral movement.

Teams Rely on Cloud RADIUS to Segment Access

Use cloud identity context, device signals, and risk metrics to segment users and devices on your network.

The Benefits Don’t Just Stop at Security

Cloud RADIUS doesn’t just enhance network security. It provides measurable benefits for your organization.

Less manual work

Reduce VLAN change tickets and one-off exceptions by enforcing segmentation policy during authentication.

Fewer disruptions

Centralize authentication and policy decisions so access remains consistent as environments change.

Reduce credential-driven incidents

Use certificate-based, passwordless authentication to reduce exposure to stolen and reused passwords.

Managed service

Offload RADIUS infrastructure maintenance while integrating directly with cloud identity and device management tools.

How It Works

See Policy-Driven Segmentation in Action

Cloud RADIUS evaluates identity, device posture, and risk signals at authentication time to assign the correct VLAN automatically.

Corporate VLAN AssignmentBYOD Restricted SegmentQuarantine Isolation

An employee on a managed, compliant device authenticates with a certificate. Cloud RADIUS validates identity, device posture, and risk — then assigns the Corporate VLAN with full network access.

STEP 1

Certificate Presented

An employee connects to Wi-Fi using a hardware-backed certificate provisioned through Intune or Jamf.

STEP 2

Identity Verified

Cloud RADIUS performs a real-time lookup in Okta or Entra ID to confirm the user is an active employee with the correct group membership.

STEP 3

Compliance Confirmed

The policy engine cross-references MDM and EDR telemetry to verify the device is encrypted, patched, and reporting a low risk score.

STEP 4

Corporate VLAN Assigned

All signals pass. Cloud RADIUS returns VLAN attributes to the switch or AP, placing the device on the Corporate VLAN with full access.

A personal device connects to the network. Cloud RADIUS detects it is unmanaged and automatically assigns a restricted BYOD VLAN — limiting access to internet-only or approved SaaS apps.

STEP 1

Device Connects

A personal laptop or phone initiates a Wi-Fi connection using a user-scoped certificate or onboarding credential.

STEP 2

Identity Confirmed

Cloud RADIUS validates the user’s identity against the cloud directory and confirms they are an active, authorized user.

STEP 3

No MDM Enrollment

The policy engine checks for an MDM profile and finds none — the device is classified as unmanaged (BYOD).

STEP 4

BYOD VLAN Assigned

Cloud RADIUS assigns the BYOD VLAN with restricted network access — internet and approved SaaS only, no lateral movement to corporate resources.

A managed device fails a compliance or risk check during authentication. Cloud RADIUS automatically quarantines it into an isolated VLAN with no access to sensitive systems until the issue is remediated.

STEP 1

Connection Attempt

A managed laptop presents a valid certificate and attempts to join the corporate Wi-Fi network.

STEP 2

Risk Signal Detected

Cloud RADIUS queries CrowdStrike or SentinelOne and receives a High risk score indicating an active threat or missing security agent.

STEP 3

Compliance Failure

The MDM reports the device is missing a critical OS patch or has disk encryption disabled, violating the segmentation policy.

STEP 4

Quarantine VLAN Assigned

The device is placed on the Quarantine VLAN — fully isolated from production systems with access limited to a remediation portal.
