Our take
What our shortlists say about the one we picked.
- Silverfort Identity Threat Detection & 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.
