CISA’s CI Fortify Rewrites the Disconnection Playbook for Critical Infrastructure

Key Takeaways

• CI Fortify mandates isolation and recovery planning for all 16 sectors
• Assumes adversaries already inside OT networks during geopolitical conflicts
• Operators must sustain essential services for weeks to months without vendors
• Legal holds face challenges when cloud preservation tools become unavailable
• Funding gaps persist; state grants and sector agencies may fill them

Pulse Analysis

The Cybersecurity and Infrastructure Security Agency’s CI Fortify marks a doctrinal shift from checklist‑style resilience to a survivable‑state mindset. By treating digital disconnection as a planned operating condition, CISA acknowledges intelligence warnings that nation‑state actors like China’s Volt Typhoon have likely embedded themselves in U.S. operational‑technology (OT) environments. This guidance pushes utilities, pipelines and other operators to harden air‑gapped capabilities, document recovery procedures and test backups, echoing similar Five Eyes initiatives that have long advocated for offline continuity.

For cybersecurity, legal‑tech and eDiscovery teams, the implications are immediate. Traditional vendor‑dependent monitoring, cloud‑based forensic telemetry and third‑party preservation tools become unreliable under the isolation assumption, forcing a reevaluation of FRCP Rule 37(e) preservation standards and incident‑response retainer SLAs. Organizations must map every preservation dependency, embed isolation‑readiness questions in vendor risk questionnaires, and expand tabletop exercises to include weeks‑long disconnect scenarios.

Economic realities present the biggest hurdle. Building hot‑standby infrastructure capable of operating without external connectivity entails significant capital outlay, a cost many operators deem prohibitive. While New York’s $2.5 million grant program offers a modest boost, broader funding will likely depend on sector risk‑management agencies and congressional appropriations. Vendors such as Xage, Xona and Elisity are positioning their identity‑and‑access solutions as essential components of the new isolation architecture, but the sector will need clear financial signals before large‑scale redesigns become feasible.
