TL;DR: Identity security vendors collectively address governance, privilege, detection, and authentication, but their coverage is only as complete as the applications already discovered and integrated, according to Zluri. Mid-market environments are especially exposed because shadow IT and unmanaged SaaS sit outside the control plane, making visibility the real prerequisite.

By the numbers:
- The actual application landscape is typically 30 to 50 percent larger than the IT-maintained list, and growing.
- The directory shows 80 integrated applications.
- 180., s actively use 180.
Questions worth separating out
Q: How should security teams evaluate identity security coverage in a fragmented environment?
A: They should compare the platform’s connected scope with the actual application and identity estate, including SaaS, admin accounts, service accounts, and API integrations.
Q: Why do identity governance tools fail when discovery is incomplete?
A: They fail because governance tools only work on systems they can see and integrate.
Q: What breaks when SaaS admin accounts and service accounts sit outside IAM scope?
A: What breaks is the assumption that central identity controls cover the whole environment.
Practitioner guidance
- Measure identity coverage before control coverage Compare the IT-maintained application inventory with actual SaaS usage, admin accounts, service accounts, and API integrations.
- Build continuous discovery into the identity programme Use discovery processes that update as new applications, shadow tools, and machine identities appear, rather than relying on quarterly reviews.
- Re-scope IGA and PAM against the real estate Identify which applications, privileged accounts, and non-human identities are outside current integrations, then prioritise bringing those systems into the governance boundary.

Identity security has a prerequisite problem, not just a tooling problem. The market has optimised downstream controls for authentication, governance, privilege, and detection, but those controls only work on identities and applications already in scope. That means a platform can be technically correct and operationally incomplete at the same time. The practitioner conclusion is that scope completeness must be evaluated before control maturity.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
- 92% of organisations expose NHIs to third parties, raising concerns about supply chain security.
A question worth separating out:
Q: How can organisations keep zero trust aligned with actual identity scope?
A: They need authoritative discovery as a standing input to policy design, not a one-time project. Zero trust depends on knowing which users, systems, and non-human identities actually exist, where they connect, and which are still outside governance. Without that, least privilege and continuous verification are only partially enforceable.
