TL;DR: SASE and CASB both extend cloud access control, but they solve different problems: SASE unifies networking and security, while CASB focuses on cloud application visibility and policy enforcement, according to StrongDM. The practical issue is not choosing a brand, but deciding which access boundaries, control planes, and governance gaps your programme still leaves open.

Questions worth separating out
Q: How should security teams decide between SASE and CASB for cloud access governance?
A: Teams should decide based on which control problem they are solving.
Q: Why do SASE and CASB still leave identity governance gaps?
A: They leave gaps when the organisation treats platform coverage as the same thing as lifecycle control.
Q: What breaks when cloud access is governed only through network and SaaS tools?
A: What breaks first is accountability.
Practitioner guidance
- Define the primary control plane for cloud access decisions Separate routing and inspection functions from entitlement and approval functions.
- Inventory identities beyond human users Map service accounts, API keys, tokens, and third-party connectors that reach cloud apps through the same environment.
- Test offboarding across cloud access paths Verify that revoking a user, token, or integration actually removes access in both cloud app controls and the surrounding access fabric.
What's in the full article
StrongDM's full article covers the product-level comparison and deployment detail this post intentionally leaves for the source:
- Deployment differences between cloud-delivered SASE and on-prem or service-based CASB options.
- Feature-by-feature explanations of SWG, FWaaS, ZTNA, and cloud application visibility in the vendor's framing.
- Pricing and flexibility comparisons that teams can use when evaluating implementation tradeoffs.
- The vendor's FAQ section on how SASE, CASB, and zero trust relate in practice.

SASE and CASB are control-plane choices, not identity strategies. The article is useful because it separates broad access orchestration from cloud application control, but identity governance still has to decide where authority lives. When access decisions are split across network tooling and SaaS policy layers, auditability becomes weaker and lifecycle offboarding becomes less reliable. The practitioner takeaway is to assign one owner to each access decision path, not to assume a platform bundle resolves governance.
A few things that frame the scale:
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, according to Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, which shows how easily access governance loses sight of machine identities.
A question worth separating out:
Q: How can organisations tell whether zero trust is actually working in cloud environments?
A: Zero trust is working when access decisions are tied to current identity state, current entitlement state, and current context rather than to assumed trust from a prior session. If users, tokens, and service accounts can still reach cloud apps after their authority should have ended, the model is not fully implemented. The strongest signal is clean revocation across all paths.
