Individually certified components fail at the point of inter-domain interaction.
Conventional frameworks such as NIST validate vendors or systems within discrete domains. The ASR Engine validates the space between them — where CrowdStrike met Microsoft, and where the next cascade will start.

Sentinel Engine by ASR
The deployed software layer of the ASR framework — node registries, cross-domain fragility scoring, and live System Resilience Value tracking.
Visit engine.aquarianresilience.comThe validation gap NIST was not designed to close.
Existing frameworks certify components inside a single domain. When those components are integrated across domains — digital into physical, physical into institutional — no framework in the certifying stack owns the interaction. ASR operates across all six domain layers simultaneously to find and quantify that interaction risk.
“CrowdStrike met Microsoft, and both were certified.”
The 2024 global IT outage was not caused by an uncertified component. It was caused by two individually certified components interacting at a boundary neither vendor owned. This is the class of failure ASR is built to anticipate.
Node registry, layered analysis, and net-fragility metrics.
Registers nodes across the six domain layers with exposure, dependency, and replaceability scoring per node.
Maps sovereign flows across single-path and multi-path networks to surface convergence points.
Calculates net fragility per node and feeds the composite System Resilience Value (SRV).
Observe trigger behavior, node prioritization, and shock propagation — before it matters.
ASR conducts smoke testing using digital twins to observe trigger behavior, node prioritization, and the real-time propagation of shocks through pivot nodes. This process quantifies shock magnitude, propagation timing, and the scope of affected systems.
