Messaging infrastructure handles valuable credentials, customer data and billable traffic. Security needs to cover both software access and telecom operations.
Protect every connection
Restrict network access, rotate SMPP and API credentials, use encrypted transport where supported and keep production credentials separate from test environments.
Limit operational permissions
Users should only access the customers, routes and actions required by their role. Administrative changes should be attributable to a specific account.
Monitor traffic anomalies
Unexpected destination changes, volume spikes, repeated failures and unusual senders can indicate misuse or configuration errors. Alerts should be connected to an incident process.
