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.
NHIMG editorial — based on content published by StrongDM: Zero Trust vs. SASE: Everything You Need to Know
By the numbers:
- SASE spending is expected to reach $9.2 billion, up nearly 40% since 2022.
- By 2025, 80% of enterprises will have adopted a SASE framework to unify web, cloud services, and private application access.
Questions worth separating out
Q: How should security teams use SASE without losing Zero Trust discipline?
A: Security teams should use SASE as an enforcement layer, not as a substitute for identity governance.
Q: What breaks when organisations assume SASE automatically delivers Zero Trust?
A: What breaks is the assumption that stronger network control equals stronger trust control.
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.
Practitioner guidance
- Separate identity governance from network enforcement Document which access decisions belong to IAM, PAM, and lifecycle controls before evaluating any SASE deployment.
- Validate Zero Trust at the entitlement layer Test whether authentication, authorisation, and continuous validation still happen independently of network location.
- Review non-human access paths separately Map service accounts, API keys, and automation flows to ensure they are not hidden inside a network-centric trust design.

Zero Trust and SASE solve adjacent problems, not the same control problem. Zero Trust is an access governance model that depends on explicit identity verification and least privilege. SASE is a network and security delivery layer that can support those policies, but it does not replace the governance work beneath them. The practitioner takeaway is straightforward: architecture convergence does not eliminate identity separation of duties.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to Ultimate Guide to NHIs.
- Another finding from the same research shows that 97% of NHIs carry excessive privileges, which is why access design cannot be assumed to be correct just because a platform centralises enforcement.
A question worth separating out:
Q: What is the difference between SASE and Zero Trust in practice?
A: In practice, Zero Trust is the governance logic that decides who or what should get access, while SASE is the architecture that helps enforce those decisions across the network. Zero Trust is narrower and identity-led. SASE is broader and combines networking, security, and policy delivery. Teams need both, but they solve different layers of the problem.
