Netskope vs Zscaler: what IAM teams should evaluate in CASB

TL;DR: Netskope and Zscaler both target cloud access, DLP, and visibility, but the governance question is how each model fits SaaS control, compliance monitoring, and policy enforcement across managed and unmanaged apps, according to Zluri. The real decision is not feature breadth alone, but which operating model best supports identity-aware control of cloud usage and data movement.

By the numbers:

• 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
• Only 5.7% of organisations have full visibility into their service accounts.
• 97% of NHIs carry excessive privileges, increasing unauthorised access and broadening the attack surface.

Questions worth separating out

Q: How should security teams choose a CASB for SaaS governance?

A: Start with the governance problem you need to solve.

Q: Why do unmanaged SaaS apps create identity governance risk?

A: Unmanaged SaaS creates risk because the organisation often cannot prove who owns the app, who can access it, or what data it can modify.

Q: What breaks when cloud app visibility is fragmented across tools?

A: Fragmented visibility breaks the ability to assign ownership, enforce consistent DLP policy, and remove risky apps from circulation.

Practitioner guidance

• Map SaaS enforcement requirements before comparing tools Separate inline inspection needs, API-based scanning needs, and broader ZTNA requirements so the platform selection matches the control objective rather than the product category.
• Tie app discovery to ownership and review workflows Use discovered applications, active users, and data-sharing signals to assign accountable owners and trigger review when an app becomes unmanaged or over-privileged.
• Prioritise DLP controls for high-risk collaboration paths Focus on read, modify, and delete permissions across SaaS apps, email, and endpoints, then validate that policy enforcement is consistent across those paths.
