TL;DR: DDIL environments can break authentication, authorization, and sessions when identity services are unreachable, according to Strata Identity. Identity controls need to keep working through outages, or users fall back to credential sharing and other unsafe workarounds.
Editorial analysis by NHI Mgmt Group, based on content published by Strata Identity: “Zero Trust in the dark – securing missions when the network goes down”.
By the numbers:
- By 2027, every branch must implement phishing-resistant multi-factor authentication and unify single sign-on as part of its Zero Trust strategy.
Key questions
Q: Why do disconnected operations increase the risk of credential sharing?
A: Because users still need to keep working when normal login flows fail.
Q: How should security teams implement identity continuity for remote or field operations?
A: They should design fallback identity flows that preserve authentication, authorization, and sessions when the primary provider is unreachable.
Q: What breaks in zero trust when the cloud identity provider is unreachable?
A: Continuous verification breaks because the access decision no longer has a live identity source to consult.
Practitioner guidance
- Design for continuity during IDP outage Map every critical access path to a fallback identity flow that still functions when the primary provider is unreachable.
- Test session persistence through failover Run controlled exercises where users stay logged in while identity services switch or become temporarily unavailable.
- Define degraded-mode access rules Pre-authorize what remains usable during disconnected operations, and make those rules explicit to field teams so they do not invent unsafe workarounds under pressure.
Bottom line: Zero Trust collapses quickly when its identity layer cannot be reached during outages or degraded connectivity.

Zero Trust continuity is now a control-plane problem, not just a policy problem. If the identity provider is the single point that decides access, then disconnected operations expose the fragility of the whole model. Identity governance has to account for degraded connectivity as a normal operating state, especially where mission or safety depends on uninterrupted access.
A few things that frame the scale:
- 90% of IT leaders say properly managing NHIs is essential for a successful zero-trust implementation, according to the Ultimate Guide to NHIs.
- By 2029, 40% of enterprises that successfully implement zero trust within cloud service provider environments will rely on the advanced visibility and control capabilities offered by CNAPP solutions.
A question worth separating out:
Q: When should organisations prioritise continuity over centralized verification in Zero Trust?
A: When the operating environment includes disconnected, denied, intermittent, or low-bandwidth conditions. In those cases, centralized verification alone is insufficient because access must survive outage windows without pushing users into insecure workarounds.
