## Our take

What our shortlists say about the one we picked.

### [Silverfort Identity Threat Detection & Response (ITDR)](https://cybersectools.com/tools/silverfort-identity-threat-detection-and-response-itdr)

Best for: Companies that want to block risky logins inline

Silverfort is the standalone pick for prevention, because it can stop a risky login instead of only raising an alert. That fits you if you need MFA on old systems and protocols that never supported it. Since it sits in the sign-in path, plan how you test and roll it out so a wrong block does not lock out real users.
