Netskope CASB alternatives highlight the limits of cloud visibility

At a glance

What this is: This is Zluri’s comparison of Netskope CASB alternatives, and its central finding is that cloud visibility alone does not solve the governance and integration gaps teams face.

Why it matters: It matters because IAM, IGA, and security teams need to decide whether CASB controls are actually improving access governance, or simply adding another layer that is hard to operationalise across SaaS, identities, and data flows.

By the numbers:

• 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.
• 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.

Context

CASB is a cloud access security broker, a control layer intended to visibility, monitor, and enforce policy across SaaS and cloud services. In practice, the hard part is not detecting cloud usage, but maintaining governance across fast-changing app integrations, shared data paths, and identities that sit outside traditional perimeter controls. That is why Netskope CASB alternatives are usually evaluated less on feature breadth than on whether they reduce operational friction without leaving blind spots.

For IAM and security teams, this is an identity governance problem as much as a cloud security one. SaaS apps, connectors, service accounts, and delegated access all create decision points that can outgrow manual review processes. When visibility is partial and integrations are inconsistent, the control stack starts to describe the environment less accurately than the business uses it.

Key questions

Q: How should security teams govern SaaS integrations that bypass user sessions?

A: Security teams should inventory every delegated connection that can touch sensitive data, including OAuth grants, API tokens, and service accounts. Then they should assign ownership, define review cadence, and revoke access when the business need ends. A CASB can help detect usage, but lifecycle control is what removes stale access.

Q: Why do CASB tools still leave governance gaps in cloud environments?

A: CASB tools are strongest where they can inspect a visible session, but many cloud permissions are exercised through app-to-app connections, tokens, and automated workflows. Those paths can outlive the original business need and bypass the most visible control points. That is why governance must include identity lifecycle management, not only policy enforcement.

Q: What do teams get wrong when comparing CASB alternatives?

A: Teams often compare feature lists instead of control coverage. The better test is whether the platform reduces the identity blast radius by governing access paths, logging them reliably, and supporting review and revocation across integrations. If it cannot, the organisation may gain visibility without reducing risk.

Q: When should organisations treat third-party SaaS access as privileged access?

A: They should treat it as privileged access whenever a connector, token, or integration can read, modify, or delete business data. That access should be owned, reviewed, and revoked with the same discipline used for other high-risk identities. If the vendor relationship changes, the access must not remain by default.

Technical breakdown

CASB visibility versus governance coverage

CASB tools typically sit between users and cloud services, inspecting traffic, enforcing policy, and surfacing risky activity. That works best where access is mediated through a visible session. The gap appears when access is granted through app-to-app connections, OAuth consent, API tokens, or unmanaged integrations, because those paths can bypass the same policy points that CASB is designed to inspect. In other words, cloud visibility is necessary but not sufficient for identity governance. A team can see usage and still miss the underlying entitlement structure that enables it.

Practical implication: map CASB coverage to the actual identity and integration paths in use, not just the applications on the approved list.

Why integration depth matters in SaaS security

A CASB only controls what it can reliably broker. If a platform has weak compatibility with a given cloud service, the organisation gets inconsistent enforcement, incomplete logging, or delayed detection. That matters because modern SaaS estates are not static point solutions. They are stitched together through permissions, connectors, and automated workflows that can change more quickly than security policy refresh cycles. The result is a governance mismatch: the security team believes a control exists, but the application path has moved elsewhere.

Practical implication: validate every critical SaaS integration path before relying on CASB policy as a primary control.

Policy enforcement versus identity lifecycle control

Cloud access security is often framed as a data protection problem, but many failures originate earlier in the lifecycle. Unused connectors remain active, permissions outlive the business need, and access reviews do not cover every machine or delegated identity. CASB may detect risky use, but it does not automatically retire stale access or resolve ownership. That is why CASB works best when paired with lifecycle governance, secrets management, and least-privilege reviews across both human and non-human identities.

Practical implication: combine CASB oversight with access reviews, offboarding, and secrets governance so stale access is removed rather than merely observed.

Threat narrative

Attacker objective: The attacker or rogue integration aims to reach sensitive SaaS data and actions through trusted cloud access paths that were not tightly governed.

1. Entry occurs through approved cloud applications, delegated SaaS connectors, or over-permissive app integrations rather than a single perimeter breach.
2. Escalation follows when those integrations retain broad read, write, or delete rights after the business need has changed.
3. Impact is unauthorized data exposure, policy bypass, or loss of control over cloud content and app-to-app access paths.

NHI Mgmt Group analysis

Cloud visibility without identity lifecycle control is a governance illusion. CASB can show activity, but it cannot by itself retire access, clean up stale integrations, or resolve who owns delegated permissions. When the estate includes service accounts, OAuth grants, and API keys, the question is not whether the tool can see traffic. The question is whether the programme can govern every identity that produces it. The practitioner conclusion is that visibility must be tied to lifecycle ownership, or it will overstate control.

Identity blast radius is the real comparison metric, not feature count. The strongest differentiator among Netskope CASB alternatives is how well they help reduce the number of identities, connectors, and permissions that can move data without review. That lens is more useful than generic product checklists because cloud security failures often emerge from accumulated access paths, not from one broken policy. Teams should compare controls by how much unintended access they can constrain, not by how many dashboards they expose.

CASB is strongest as an enforcement layer, weakest as an ownership model. It can inspect, classify, and block, but it does not establish durable accountability for service accounts, third-party connectors, or long-lived tokens. That means the governance burden remains with IAM, IGA, and SaaS owners. Practitioners should treat CASB as one control in a broader identity programme, not as the programme itself.

Third-party SaaS access needs the same governance discipline as internal access. The article’s discussion of cloud integrations points to a broader pattern: delegated access becomes a hidden extension of the identity perimeter. Once a connector can read, modify, or delete data, it should be governed like any other privileged identity. The practitioner implication is straightforward: if you do not inventory and review third-party access, you do not fully control the SaaS estate.

Runtime policy is not enough when entitlements stay alive after business need ends. A control that only reacts at the moment of use cannot fix the fact that access was never removed. That is why the strongest NHI governance models pair monitoring with rotation, offboarding, and review. Teams should assume that dormant access will be reused unless it is actively revoked.

From our research:

• Only 5.7% of organisations have full visibility into their service accounts, according to Ultimate Guide to NHIs.
• 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools, according to Ultimate Guide to NHIs.

What this signals

Identity blast radius will become the most useful procurement lens for CASB and SaaS governance over the next cycle. Teams that cannot tie visibility to ownership will keep buying monitoring depth without reducing delegated access risk. The practical shift is toward controls that can prove who owns a connector, who approved it, and when it should be revoked.

The data gap is already wide enough to justify stronger lifecycle discipline. If only 5.7% of organisations have full visibility into their service accounts, then many cloud governance programmes are operating with an incomplete picture of the identities that actually move data. That is a structural issue, not a tuning issue.

As cloud estates keep expanding, the question will shift from whether a platform can inspect traffic to whether it can support NHI lifecycle governance around those traffic sources. That means pairing CASB with access reviews, offboarding, and secrets discipline rather than assuming one control layer can absorb all three jobs.

For practitioners

• Map delegated SaaS access paths Inventory OAuth grants, API tokens, connectors, and service accounts that can bypass user-centric control points. Prioritise the systems where read, write, or delete rights touch sensitive repositories, finance data, or collaboration tools.
• Test CASB coverage against real integrations Validate whether your CASB enforces policy across every business-critical SaaS integration, including non-standard apps and shadow IT. Document the paths where logging, blocking, or classification is incomplete.
• Tie access reviews to ownership and offboarding Assign explicit owners to delegated access, then require review and revocation when the business use case ends. Include third-party app connections and dormant machine identities in the same lifecycle process.
• Use identity blast radius as a buying criterion Score candidates on how well they reduce over-permissioned access, expose unused connectors, and support governance of third-party access. Avoid treating dashboard coverage as a proxy for security control strength.

Key takeaways

• CASB visibility is useful, but it does not eliminate the governance problem created by delegated SaaS access and long-lived integrations.
• The practical risk is identity blast radius, where connectors, tokens, and service accounts retain access after the business need has changed.
• Teams should compare alternatives by how well they support ownership, review, and revocation across cloud access paths, not by dashboard count alone.

Key terms

• Cloud access security broker: A cloud access security broker is a control layer that sits between users or integrations and cloud services to inspect, classify, and enforce access policy. In practice, its value depends on how many identity paths it can actually govern, especially delegated access and app-to-app connections.
• Delegated SaaS access: Delegated SaaS access is permission granted to one application, connector, or service account to act on behalf of another identity or data owner. It is often necessary for automation, but it becomes a governance risk when the grant is broad, stale, or poorly owned.
• Identity blast radius: Identity blast radius is the amount of data, systems, and actions that a single identity can affect if it is misused or compromised. The larger the blast radius, the more a security team must focus on reducing scope, shortening access duration, and assigning clear ownership.
• Identity lifecycle governance: Identity lifecycle governance is the discipline of provisioning, reviewing, rotating, and revoking access as business needs change. For cloud and SaaS environments, it has to cover human users, service accounts, tokens, and third-party integrations, not just employee accounts.
