CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Teams running signup flows or fraud prevention systems that need to block disposable email registrations will find value in Disposable Email Domains because it's maintained, free, and covers 1,363 known domains across major providers. 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.
Help desk and IT support teams dealing with credential-based account takeovers will benefit most from RSA Help Desk Live Verify because it verifies both the employee and the user in real time, blocking imposters before they access sensitive systems. The bi-directional passwordless authentication covers the full NIST PR.AA function, and continuous anomaly detection (DE.CM) catches compromised sessions that traditional MFA misses. Skip this if your help desk primarily handles non-identity sensitive requests or you've already embedded strong phishing-resistant auth upstream; RSA's value is specifically in the verification handshake itself, not broader identity architecture.
