Security & Access Control

RBAC, multi-tenancy, SSO, 2FA, audit logging and compliance checks.

Security & Access Control

Security is built into every layer. Users can authenticate through local credentials, LDAP or OIDC, and enforce TOTP or FIDO2 second factors. Fine-grained RBAC, multi-tenancy and VM-level ACLs keep teams isolated, while the RBAC explorer makes it easy to review and audit who can do what.

All sensitive database fields are encrypted at rest with Fernet, and audit logs are HMAC-signed so tampering is detectable. A built-in IDS/IPS watches monitored segments with signature and anomaly detection, alerting and applying response policies when traffic looks hostile. The client portal and tenant isolation features make ProxmoxVEx ready for MSP and hosting environments.
