Cloud PBX Security: Keeping Hosted Voice Safe
Cloud PBX providers handle much of the infrastructure security, but customers still control user access, configuration, and integration points. Shared responsibility means organizations must protect their side of the service.
Identity Management
Enforce strong passwords and multi-factor authentication for admin portals. Disable departed employee accounts promptly. Limit admin permissions to those who need them.
Access Control
Restrict call-forwarding, international dialing, and premium-rate access by role. Configure class-of-service policies so a compromised basic user cannot generate expensive calls.
Integration Security
When integrating cloud PBX with CRM, SSO, or contact center platforms, use secure APIs and rotate API keys regularly. Monitor integration logs for unusual activity.
Monitoring and Auditing
Review call logs, admin changes, and user activity. Suspicious patterns such as after-hours configuration changes or unexpected call destinations deserve investigation.
