How can a wholesale SMS platform be secured and optimized using DNS-level filtering or monitoring?

Hi everyone,

I’ve been working with a wholesale SMS platform setup that handles high-volume messaging traffic, and I’m trying to understand how DNS-level tools like NextDNS could be used to improve security and visibility.

A few things I’m curious about:

• Can DNS filtering help detect or block suspicious traffic patterns related to messaging APIs or routing endpoints?
• Is it possible to monitor or log SMS platform-related domains to identify unusual behavior or abuse?
• How would you approach securing backend messaging infrastructure (like SMPP or API endpoints) using DNS-based controls?
• Are there any best practices for combining DNS filtering with telecom-level protection systems?

I’ve seen messaging environments where traffic monitoring and filtering play a big role, especially in large-scale setups like wholesale SMS platforms, so I’m trying to connect how DNS-level control fits into that architecture.

Would appreciate any insights or real-world setups from people who have worked on similar systems. Thanks!
