Who should own unmanaged SaaS applications?

Why This Matters for Security Teams

Unmanaged SaaS applications create a governance gap the moment they appear outside procurement, IAM, and security review. Ownership determines who can answer basic but critical questions: who approved the tool, what data it touches, which users can access it, and whether the app should be retained, restricted, or removed. That matters because SaaS sprawl often becomes identity sprawl, and identity sprawl is where privilege, secrets, and data exposure start to overlap. NHI Management Group’s Ultimate Guide to NHIs — Key Challenges and Risks notes that only 5.7% of organisations have full visibility into their service accounts, which is a useful proxy for how often hidden ownership problems also go unseen. The control objective is not just inventory, but accountability tied to business risk and technical enforcement. NIST’s Cybersecurity Framework 2.0 reinforces that governance and asset management are inseparable from effective security operations. In practice, many security teams encounter unmanaged SaaS only after a leaked token, a billing surprise, or a data access dispute has already forced a cleanup.

How It Works in Practice

The best owner for an unmanaged SaaS application is usually a named business owner, with a named technical owner supporting security, access, and lifecycle decisions. Those roles should not be vague committee responsibilities. The business owner decides why the tool exists, who benefits from it, and whether it still has business value. The technical owner handles access review, SSO or SCIM integration where possible, secret handling, logging, and deprovisioning. That split maps well to NHI governance because SaaS applications often rely on service accounts, OAuth grants, API keys, and automation tokens that behave like non-human identities even when the app itself is not treated that way. A practical ownership model should include:

• a single accountable business sponsor for every discovered SaaS app
• a technical custodian responsible for identity, secrets, and auditability
• a risk review for data sensitivity, third-party exposure, and contractual status
• a decision path for approve, remediate, restrict, or retire
• a required offboarding process for revoking tokens, integrations, and dormant accounts

This is where lifecycle discipline matters. The NHI Lifecycle Management Guide and Ultimate Guide to NHIs — Lifecycle Processes for Managing NHIs both reinforce that discovery without assignment, review, and revocation is not governance. Security teams should also check whether the SaaS app has generated unmanaged secrets or OAuth connections, since the operational ownership problem often becomes a credential problem quickly. These controls tend to break down in fast-moving self-service environments where employees can add apps without procurement, central SSO, or logging, because no one sees the app until a failure forces visibility.

Common Variations and Edge Cases

Tighter ownership rules often increase friction for product teams and business units, so organisations have to balance speed against control. That tradeoff is real, especially when unmanaged SaaS is supporting a temporary campaign, a shadow IT workflow, or a departmental pilot that later becomes business-critical. Current guidance suggests that even short-lived tools still need explicit ownership, but there is no universal standard for how to assign that ownership in every org structure. A few edge cases require extra care:

• Employee-chosen tools used for customer data should be treated as high risk until a real owner is assigned.
• Vendor-managed SaaS inside a larger contract still needs an internal owner for access and data decisions.
• Shared “team” subscriptions often fail when no one is responsible for offboarding, billing, or audit response.
• Automation-heavy SaaS can hide non-human identities inside integrations, so ownership must include token and secret review.

For organisations trying to align with the NHI Mgmt Group’s broader guidance, the key question is not “who installed it?” but “who can authorize its continued use and revoke its access?” That distinction matters because unmanaged SaaS often looks harmless until a dormant integration, forgotten admin account, or unreviewed data connection becomes the real incident path. The Top 10 NHI Issues is useful here because it frames ownership, visibility, and revocation as linked problems rather than separate ones. When SaaS ownership is unclear, remediation slows, exceptions multiply, and the application tends to survive long after its original business justification has disappeared.
