Authentication: control every access, human, machine or AI agent
Attackers no longer break in: they log in. Silverfort analyses every authentication request to systems in real time, extends MFA to resources that lack native support and brings service accounts and AI agents under control, with no agent on servers and no proxy.

Every authentication under control
How Silverfort identity protection works, from the access request to the decision: allow, require MFA or block.
AI-powered attacks, AI-powered defence
AI exploits every identity weakness faster than defence teams
AI-powered attacks find weak credentials, forgotten accounts and excessive privileges, then use them to take over the network. Static policies and after‑the‑fact detection fall short: every authentication has to be assessed and decided in real time.

What AI changes on the attacker side
- Automated attacks test and reuse stolen credentials at scale
- Non‑human identities and AI agents multiply, often invisible and over‑privileged
- Lateral movement relies on legacy protocols (NTLM, Kerberos) that lack MFA
How AI strengthens defence
- Real-time risk engine: every request (Kerberos, NTLM, LDAP/S, SAML, OIDC, RADIUS) is assessed, then allowed, challenged with MFA or blocked
- AI Agent Security: discovery of AI agents and their permissions, assignment to a human owner, inline runtime controls and least privilege
- Identity Threat Detection and Response (ITDR): high‑confidence alerts and automatic response (MFA, session termination, identity isolation), shared with the SIEM or XDR in place
FEATURES
Every identity, including those the IAM cannot see
Universal MFA
- MFA extended to legacy applications, servers and command‑line tools
- Compatible with the existing MFA technology
- Zero application changes
Service accounts and non‑human identities
- Automatic discovery and classification
- Owner assignment, detection of orphaned accounts
- Use restricted to the intended source and destination, with no password rotation
Authentication firewall
- Blocks lateral movement and ransomware propagation
- Identity‑based segmentation
- Quick to enable, including during incident response
Privileged access
- Just-in-time access, with zero standing privileges
- Time windows and alerts on sensitive accounts
- Deployment in days rather than years
Identity posture
- Shadow admins, dormant accounts, obsolete protocols
- Excessive privileges and misconfigurations
- Guided remediation procedures
End‑to‑end visibility
- Unified inventory of human and non‑human identities
- Graph of hidden access paths
- On premises and in the cloud: AD, Entra ID, Okta, Ping
HOW IT WORKS
A second opinion on every authentication
- RequestA user, a service or an AI agent requests access to a resource
- Second opinionThe directory validates the credential, then forwards the request to Silverfort
- DecisionThe engine calculates the risk and allows, requires MFA or blocks
- SharingAlerts and risk data shared in real time with the SIEM, XDR and Identity Guard
