Strengthen access control with Silverfort’s Authentication Firewall
Static network segmentation and traditional AD permissions weren’t built for today’s dynamic identity threats. Once attackers obtain valid credentials, they can move laterally, escalate privileges, and spread ransomware—often undetected.
The Silverfort Authentication Firewall changes that. It enforces real-time, identity-based access control directly at the authentication layer, giving organizations the ability to detect, block, and contain malicious activity before it spreads. By analyzing every authentication attempt—across Kerberos, NTLM, LDAP, cloud, and local logons—Silverfort applies deny and segmentation policies dynamically, preventing unauthorized access and isolating compromised identities instantly.
Instead of relying on static controls, security teams gain live enforcement that adapts to user behavior and risk. The result is immediate containment, reduced blast radius, and consistent least-privilege enforcement across hybrid environments.
In this solution brief, you’ll learn how to:
- Contain active breaches the moment they occur by isolating compromised identities and reducing impact.
- Enforce deny and segmentation policies in real time at the authentication layer across AD, cloud, and local accounts.
- Block risky authentications instantly to prevent privilege escalation and ransomware spread.
