Silverfort introduces a revolutionary new approach that enables secure authentication and access across enterprise networks and cloud environments in a holistic and non-intrusive way.

By seamlessly applying a layer of protection on top of existing authentication protocols, Silverfort eliminates the need to deploy any agents and proxies, or to make any changes to existing servers and applications. This enables organizations to protect assets that don’t support secure authentication today without having to modify them, and to extend protection to interfaces that are not covered by any other MFA solution.

Silverfort’s platform monitors all human and machine access requests, across all systems and environments, continuously analyzing risk and trust levels in real-time, applying adaptive risk-based authentication policies and preventing unauthorized access to any sensitive asset.

and Endpoints

Access Requests

(Kerberos, LDAP, NTLM, SAML, OIDC, RADIUS, etc.)

and Resources

(on-prem & cloud)

Identity Stores

(Active Directory, Cloud-Native IdPs, RADIUS, etc.)

2nd Authentication

(Silverfort or 3rd party)

Step by Step:

  • 1Authentication request sent to the identity store
  • 2Identity store performs standard verification
  • 3The response is routed to Silverfort, using native features of the directory server (no agent is required) and with built-in failover
  • 4Silverfort analyzes the message in real-time, calculates risk using AI, and applies policy (allow/deny/MFA)
  • 5If needed, Silverfort verifies the user's identity using MFA
  • 6If access is permitted, Silverfort returns the message to the identity store, and from there to the unaware client/server


In today’s perimeterless networks, with countless different users, devices and systems communicating with each other across dynamic on-premise and cloud environments, it is no longer possible to assume trust. Validation of user identities and continuous analysis of risk and trust levels are becoming essential, especially for those looking to implement a Zero Trust security approach. However, implementing secure authentication and access system-by-system with agents and proxies is not realistic, nor will it provide the needed results.

Silverfort’s unique agentless and proxyless solution is possible thanks to a combination of several innovative technologies:

Ability to Monitor Authentication and Access Requests Without Agents or Proxies

Non-Intrusive Analysis
of Encrypted
Authentication Protocols

Holistic and Continuous
AI-Driven Risk Analysis


The only solution that can enable MFA for systems and interfaces that couldn’t be protected until today, including homegrown and legacy applications, critical infrastructure, file systems, databases, and admin access tools such as PsExec that currently allow attackers to bypass agent-based MFA.

The only holistic authentication solution that delivers unified authentication and access policies across all users, assets and environments, both on-premises and in the cloud, instead of protecting assets one-by-one which is no longer practical.

A powerful AI-driven risk and trust engine, continuously analyzing all human and machine access requests based on 20x-50x more data than any other risk-based authentication solution – not only at the perimeter but within the network too.

The only non-intrusive authentication platform: does not require software agents, inline proxies or any code changes on individual servers/applications. This allows customers to extend secure authentication and access to all sensitive assets, even in complex hybrid environments.

Improves the user experience
and minimizes disruptions
by reducing the number of MFA requests to sensitive and high-risk situations.
