Air-gapped networks are designed for maximum security—but they’ve traditionally lacked one critical control: MFA. Silverfort changes that with the only MFA solution purpose-built for air-gapped environments, eliminating the need for code changes or internet connectivity.
This solution brief introduces how Silverfort enables multi-factor authentication for all Active Directory authentications in fully disconnected networks without disrupting operations or compromising system integrity.
What makes it different?
- No reboots, no updates: Ideal for 24/7 critical infrastructure with zero downtime tolerance
- Protect legacy systems without code changes: Apply MFA to any authentication flow—NTLM, Kerberos, LDAP—out of the box
- FIDO2 token support: Secure authentication using any hardware token, even in isolated environments
The included diagram clearly illustrates how Silverfort integrates with AD to authenticate users, admins, non-human identities, and systems—without requiring any changes to the applications or their authentication mechanisms.
If you operate OT, ICS, or highly secure air-gapped systems, this guide is your roadmap to adding robust identity protection—seamlessly.
