TL;DR: CASB software is framed as a cloud security control, but this article shows that its real value is visibility, policy enforcement, and compliance across sanctioned and unsanctioned cloud apps, according to Zluri. The identity lesson is that SaaS risk management depends on knowing which users, accounts, and connections exist before you can govern access or data exposure.

By the numbers:
- Zluri has deep integrations with 300+ applications, including SSO.
Questions worth separating out
Q: What breaks when CASB tools cannot see all SaaS applications?
A: When CASB tools cannot see all SaaS applications, shadow IT, unmanaged sharing, and unknown privileges remain outside policy control.
Q: Why do CASB controls matter for non-human identities in SaaS?
A: CASB controls matter for non-human identities because service accounts, API tokens, and delegated app connections can move data without a human session.
Q: How do teams know whether CASB visibility is actually complete?
A: Teams know visibility is incomplete when discovery results differ across API, SSO, browser, and endpoint sources, or when unsanctioned apps appear only after an audit or incident.
Practitioner guidance
- Map SaaS discovery to identity sources Confirm which applications, sessions, and accounts your CASB can actually see through API, SSO, browser, and agent-based sources.
- Separate human and non-human SaaS activity Tag service accounts, API-driven sessions, and delegated app connections differently from end-user sessions so policy, review, and incident response can follow the correct identity type.
- Tie DLP policies to real SaaS data paths Anchor sensitive-data controls to upload, share, sync, export, and cross-app handoff events rather than generic traffic patterns, especially where sanctioned SaaS collaboration is the main exposure point.
What's in the full article
Zluri's full article covers the operational detail this post intentionally leaves for the source:
- A 15-vendor comparison with feature-by-feature notes for teams shortlisting CASB tools.
- Product-specific pros and cons for each platform, including deployment and usability trade-offs.
- The vendor's own reasoning for why SaaS management differs from traditional CASB coverage.
- Coverage notes on which cloud services and app types each tool claims to support.

CASB is now an identity visibility problem, not just a cloud filtering problem. The article repeatedly returns to discovery, sanctioned versus unsanctioned apps, and policy enforcement. That is the real signal for practitioners: the control value of CASB rises or falls with identity context, not with inspection depth alone. Organisations that cannot connect cloud activity back to users, accounts, and privileges will keep missing the access path that matters. The practitioner conclusion is that CASB must be assessed as part of identity governance, not as a separate security box.
A few things that frame the scale:
- The average organisation believes more than 1 in 5 of their non-human identities are insufficiently secured, according to The 2024 ESG Report: Managing Non-Human Identities.
- 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, with 46% confirmed and 26% suspected.
A question worth separating out:
Q: How should organisations decide where CASB fits in the security stack?
A: Organisations should place CASB between identity governance, SaaS access control, and data protection rather than treating it as a standalone cloud tool. The right decision is based on whether the organisation needs app discovery, DLP enforcement, or policy visibility for both human and non-human access paths.
