The hardest systems to change are the easiest to attack.
Most enterprises run legacy and OT systems that can’t be modernized and can’t support modern Identity Security. They’re a top target for attackers and a common source of compliance gaps. Silverfort protects AD, legacy, and OT systems by enforcing MFA and access-based controls at runtime, with no changes and no downtime.
Legacy and homegrown apps, OT, and air-gapped systems run critical operations, but they were never built for modern Identity Security. Many still authenticate to Active Directory over legacy protocols like NTLM and LDAP, and they can’t be refactored, retired, or taken offline to fix it. The result is blind spots in MFA coverage, service accounts no one owns, and environments outside identity controls.
How Silverfort protects AD, legacy, and OT systems
Silverfort’s patented Runtime Access Protection™ (RAP) technology integrates natively with AD and enforces controls inline, at runtime. Legacy systems keep using their existing authentication protocols, and nothing needs to change, even in OT and air-gapped networks. With it you can:
- Extend MFA to legacy and homegrown apps, command-line tools, OT systems, and Windows local accounts
- Protect the service accounts these systems run on, without password rotation
- Control what legacy systems can access with Zero Trust policies and identity segmentation at the authentication layer
No changes. No downtime. No rip-and-replace.
In this brief, you’ll learn:
- Why legacy, OT, and air-gapped systems are the easiest to attack and a common source of compliance gaps
- How Silverfort extends MFA, service account protection, and access controls to systems that can’t be modified
- How to reduce AD compromise risk, pass audits and attestations, and cut technical debt
