Silverfort

Overview

Silverfort is an ITDR and identity security platform that sits at the authentication layer rather than at individual endpoints. It integrates with directories like Active Directory and Entra ID to monitor and enforce policy on every authentication, including the legacy protocols and service accounts that traditional MFA and detection tools cannot touch. See the full ITDR category and the best ITDR tools ranking.

What it is good at

Reach is the differentiator. By operating as an overlay on the authentication path, Silverfort applies MFA and risk policy to Kerberos, NTLM, LDAP, and command-line access where agents and proxies fall short. Service account discovery and protection are a genuine strength, as is detecting lateral movement and abnormal authentication behavior across hybrid AD and Entra ID. Deployment is agentless, so it covers systems that cannot run an endpoint agent, which is exactly where most organizations have blind spots.

Where it falls short

It is an overlay, not an identity provider, so it complements rather than replaces your directory. Value is concentrated in environments with a meaningful Active Directory footprint; the cloud-only story is less compelling. Initial tuning to avoid breaking legitimate authentication takes care, and pricing is quote-based with no public transparency. It is a protection-and-detection layer, not a full SIEM or directory-recovery tool.

Pricing

Quote-based and not published, generally scaling with protected users and service accounts. Expect enterprise sales engagement and annual contracts; model the cost with the TCO calculator.

Best for, and who should look elsewhere

Choose Silverfort for hybrid AD environments that need MFA and threat detection on protocols nothing else can protect, and to secure service accounts and legacy systems without code changes. For AD-recovery depth instead, compare Silverfort vs Semperis; for XDR-correlated identity detection, see CrowdStrike Falcon Identity Protection.

Bottom line

A strong choice for hybrid AD shops needing MFA and ITDR on protocols nothing else can protect, and less relevant if you are fully cloud-native.
