Silverfort

Overview

Silverfort is an 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 legacy protocols and service accounts that traditional MFA and detection tools cannot touch.

Capability deep-dive

The differentiator is reach. By operating as an overlay on the authentication path, Silverfort can apply MFA and risk policy to things like 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 auth behavior. The weaknesses: it is an overlay, not an identity provider, so it complements rather than replaces your directory. Value is concentrated in environments with meaningful AD footprint, and the cloud-only story is less compelling. Initial tuning to avoid breaking legitimate auth takes care.

Pricing

Quote-based and not published. Pricing generally scales with protected users and/or service accounts. Expect enterprise sales engagement and annual contracts.

Bottom line

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