The list updates regularly on GitHub and integrates into most identity verification pipelines with minimal friction. Skip this if you're looking for behavioral signals or account takeover detection; this tool does one thing,block throwaway addresses,and doesn't pretend to do more.

Glide Identity Glide-In

SMB and mid-market operations managing physical and logical access without dedicated identity infrastructure will see immediate value in Glide Identity Glide-In's SIM-based verification, which eliminates the cost and complexity of hardware tokens or complex PKI deployments. The tool maps directly to NIST CSF 2.0's PR.AA function for access control and carriers already validate identity as part of their core business, removing a dependency on your team to maintain cryptographic material. Skip this if you need deep integration with legacy access control systems or run in regions where carrier partnerships are sparse; Glide-In is cloud-native and assumes modern, telecom-friendly deployments.
