TL;DR: Running a SASE enforcement plane inside AWS, Azure, and GCP regions reduces transit jitter, hairpinning, and PoP saturation by keeping inspection close to destination SaaS and on private backbone paths, according to Island. The architectural shift matters because network control quality now depends as much on substrate choice and regional elasticity as on policy logic.
Editorial analysis by NHI Mgmt Group, based on content published by Island: “Why We Built Our SASE Enforcement Plane on Hyperscalers”.
Key questions
Q: What breaks when SASE inspection is tied to a fixed PoP model?
A: Fixed PoP designs can create hairpinning, transport jitter, and saturation cliffs because traffic must travel farther before it is inspected.
Q: Why does hyperscaler-based SASE improve latency and resilience?
A: It improves both because traffic can enter near the user, stay on private backbone segments, and be processed in the region closest to the destination SaaS application.
Q: How do teams tell whether their SASE architecture is actually working?
A: Look for low jitter, stable tail latency, and consistent session behaviour during regional or traffic surges.
Practitioner guidance
- Evaluate pathing before policy features Map where user traffic enters, where inspection occurs, and whether SaaS destinations remain on a short private path or get hairpinned through remote PoPs.
- Test resilience under regional degradation Review how the architecture behaves when a cloud region, availability zone, or routing segment degrades, including whether sessions continue without manual failover intervention.
- Measure latency at the enforcement point Baseline jitter, tail latency, and packet loss for representative SaaS sessions before and after inspection so you can separate policy effects from transport effects.
Bottom line: Hyperscaler-based SASE changes the control problem by tying enforcement quality to routing path, regional placement, and substrate resilience, not just policy logic.

Hyperscaler pathing is becoming a control-quality issue, not a networking preference. When enforcement depends on where traffic physically lands, the security model inherits the strengths and weaknesses of the transport substrate. That means latency, resilience, and inspection consistency are part of the control itself, not merely operational background noise. For practitioners, the decision is whether the SASE layer is governed as a policy engine alone or as a policy-plus-path system.
A question worth separating out:
Q: Should security teams prioritise path reliability or policy sophistication in SASE design?
A: Path reliability should come first when the enforcement model depends on real-time traffic handling. Sophisticated policy cannot compensate for a brittle transport layer that creates detours, brownouts, or packet loss. The stronger architecture aligns inspection location, routing health, and destination proximity before tuning advanced policy logic.
