Reality Check
What Your Air-Gapped Environment Actually Faces
The assumptions that keep critical infrastructure vulnerable—and the operational realities that demand a purpose-built identity platform.
Common Assumption
“Our air gap keeps us secure.”
The 2026 NERC CIP Roadmap acknowledges the air gap is a myth. Ransomware targets the physics of the grid, and every USB drive, maintenance laptop, and firmware update is an ingress path. Without strong identity, isolation is a single layer—not a strategy.
Operational Reality
Identity is the real perimeter
CISA and international partners confirm that adversaries win by abusing access through compromised identities and overprivileged accounts. When you can’t rely on the network, you must secure the identity and the transaction.
Common Assumption
“Passwords are enough for isolated systems.”
Shared credentials on SCADA HMIs and network switches are the #1 finding in OT security assessments. Without MFA, a single compromised password gives an adversary the same access as your most trusted operator.
Operational Reality
MFA must work entirely offline
Cloud-dependent MFA (SMS, push, cloud FIDO) is impossible in air-gapped environments. Operators need phishing-resistant authentication that runs on local infrastructure with no external calls—ever.
When Identity Fails In Isolated Environments
5:12 AM — Power Grid Control Room
The Locked-Out Operator
A shift operator’s password expires at a substation with no internet. Without on-premises self-service reset, they wait 4 hours for a technician to drive on-site. Meanwhile, automated alerts go unacknowledged and grid stability degrades.
2:30 PM — Water Treatment Facility
The Shared Credential
Three operators share one login for the SCADA system because individual MFA was never possible without cloud services. A disgruntled contractor uses the shared account to alter chemical dosing parameters. The audit log shows nothing actionable.
11:45 PM — Defense Network Operations
The Unpatched IdP
The identity server hasn’t been upgraded in 3 years because every available update requires cloud FIDO services the classified network can’t reach. Known CVEs remain unpatched, and the compliance team flags the gap every quarter.
Business Outcomes
The Impact Of Purpose-Built Air-Gapped Identity
SecureAuth AirGap delivers measurable improvements across security posture, operational efficiency, and compliance readiness.
95%
Reduction in Credential-Based Risk
Phishing-resistant FIDO2 and enforced MFA eliminate the primary attack vector for air-gapped environments: compromised passwords and shared credentials.
4h→5m
Password Reset Resolution
On-premises helpdesk verification replaces physical site visits for credential resets. Operators regain access in minutes instead of waiting hours for a technician.
100%
Audit Event Coverage
Every authentication, enrollment, reset, and admin action is logged locally. Compliance teams get complete evidence without assembling it manually from disparate systems.
0
External Dependencies
No cloud services, no internet callbacks, no SMS gateways. The entire identity platform operates within your sovereign boundary with zero external connections.
1
Single ISO Deployment
Deploy the full identity stack from a single ISO image. Modular microservices mean you can upgrade FIDO or Mobile services independently without platform downtime.
24/7
Identity Availability
Redundant IdP servers ensure authentication never goes down. Designed for continuous operations where identity outages have real-world safety consequences.
Platform Capabilities
Everything You Need. Nothing That Phones Home.
SecureAuth AirGap delivers the full lifecycle of modern identity—authentication, enrollment, management, and compliance—entirely within your isolated environment.
Phishing-Resistant Authentication, Fully On-Premises
Every authentication flow executes entirely within your air-gapped boundary. No cloud callbacks, no SMS gateways, no push notification infrastructure. Operators authenticate to workstations, applications, and network equipment using enterprise-grade MFA that was built for isolation.

Spotlight: Network Infrastructure Security
RADIUS Authentication For Critical Network Equipment
Network switches, routers, and firewalls are the backbone of OT environments. SecureAuth brings MFA-protected RADIUS authentication entirely on-premises.
Why RADIUS Matters In Air-Gapped Environments
Critical infrastructure relies on hundreds or thousands of network devices—each one a potential entry point. RADIUS provides centralized AAA management, but without MFA integration, it depends on shared secrets and local accounts that adversaries actively target.
SecureAuth extends RADIUS with multi-factor authentication that works entirely within the air gap. Operators authenticate to switches and routers using their enterprise identity plus a second factor—no cloud callbacks, no SMS, no push notifications required.

Energy & Power Grid Operations
Protect access to SCADA/EMS systems, substation controls, and generation management consoles. RADIUS integration secures networking equipment across substations while maintaining NERC CIP compliance with full audit trails.
USE CASE 02
Defense & Classified Networks
SIPRNet, JWICS, and other classified environments require air-gapped identity with no external dependencies. Phishing-resistant MFA with YubiKey HOTP and FIDO2 for workstation login, application access, and privileged operations.
USE CASE 03
Water & Wastewater Treatment
