TL;DR: Zero Trust verifies every access request continuously while SASE combines networking and security services, and StrongDM frames the two as complementary rather than interchangeable. The practical issue is that IAM teams still need explicit authorization, lifecycle, and privilege controls because SASE does not automatically deliver Zero Trust.
Editorial analysis by NHI Mgmt Group, based on content published by StrongDM: “Zero Trust vs. SASE: Everything You Need to Know”.
By the numbers:
- SASE spending was expected to reach $9.2 billion, up nearly 40% since 2022.
Key questions
Q: What should IAM teams separate when comparing Zero Trust and SASE?
A: IAM teams should separate access governance from access delivery.
Q: Why does SASE not automatically deliver Zero Trust?
A: SASE can include Zero Trust capabilities, but it does not by itself establish the identity controls Zero Trust depends on.
Q: What breaks when privilege governance is missing in a SASE model?
A: When privilege governance is missing, organisations can end up with modern access paths and outdated permissions at the same time.
Practitioner guidance
- Separate identity governance from network delivery Define which controls belong to IAM, IGA, and PAM, and which belong to the SASE layer.
- Map Zero Trust to explicit authorization points Identify every place where access is currently inferred from network location, then replace that assumption with authenticated and continuously validated access decisions.
- Keep standing privilege out of the access fabric Review whether the same identities that enter through SASE paths also retain long-lived permissions in databases, servers, or cloud services.
Bottom line: Zero Trust and SASE solve different problems, with one focused on access governance and the other on security delivery across distributed environments.

Zero Trust and SASE should be separated by governance function, not by marketing category. Zero Trust is an access decision model, while SASE is a service-delivery architecture. When teams blur those layers, they risk treating network consolidation as if it were identity assurance. The practical conclusion is that IAM, PAM, and NHI controls still need to stand on their own.
A few things that frame the scale:
- 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 Zero Trust over SASE?
A: Organisations should prioritise Zero Trust first when the main risk is uncontrolled access rather than network sprawl. If entitlement design, privileged access, and continuous verification are weak, adding SASE only improves the delivery path. The better sequence is to establish identity-led policy and then use SASE to enforce it consistently across distributed access points.
