Shadow IT risk should not sit with one team alone. The article frames it as a shared responsibility between IT and security leadership, especially the CISO and SecOps, because both visibility and remediation are needed. Procurement controls help, but they are not enough. Ownership must extend to discovery, review, and ongoing governance of unsanctioned SaaS use.
Shared ownership is the only workable model
Shadow IT risk becomes a governance problem the moment a business unit adopts a SaaS tool without formal procurement, because the organisation has already created an unsanctioned access path to data, users, and integrations. The right ownership model is shared: IT provides discovery and control points, while security leadership owns risk prioritisation, remediation pressure, and ongoing oversight.
That split matters because the risk is not just “who bought the app.” It is who can see it, who can assess the data it touches, and who can make a decision when the tool sits outside normal approval paths. A single-team ownership model usually fails because no one team has both operational visibility and authority over the full lifecycle.
When unsanctioned SaaS appears, the practical question is whether the tool is merely tolerated or actively governed. If it connects to corporate identity, stores sensitive data, or has API and third-party access, it belongs in the same review logic as any other externally exposed service. NHIMG’s The 2026 Infrastructure Identity Survey is a useful companion for understanding how access governance and least privilege expectations scale across modern estates.
Why procurement controls help, but do not solve shadow IT
Formal procurement is a gate, not a control plane. It can reduce blind buying and contract risk, but it cannot discover every browser-installed workflow, departmental SaaS trial, or third-party integration that lands after an employee starts using it. That is why ownership must extend beyond procurement into discovery, review, and enforcement.
The strongest ownership models treat procurement as one signal among several. Security and IT need inventory sources such as SSO logs, CASB or SaaS discovery telemetry, DNS and network observations, and user-reported exceptions. Once the application is found, ownership shifts to determining whether it should be onboarded, restricted, or retired. NHIMG’s Ultimate Guide to Non-Human Identities is relevant here because unmanaged SaaS often introduces tokens, API keys, and third-party access that behave like identity-bearing assets.
Ownership also has to account for ongoing change. A tool that is low-risk at pilot stage can become a data-processing and integration risk after a team connects it to customer records, shared drives, or automation. The owning function therefore needs enough authority to reopen the review when scope changes, not just when procurement is bypassed.
What ownership should include in practice
For shadow IT, ownership should be defined as a lifecycle duty, not a one-time approval. The owner should be accountable for finding the tool, classifying its business use, checking what data and access it consumes, and deciding whether the organisation will sanction it, contain it, or remove it.
- Discovery: establish which teams or systems can identify unsanctioned SaaS use early.
- Review: assess data sensitivity, integration scope, and access paths before the tool spreads further.
- Remediation: revoke, segment, or formalise the tool based on business need and risk.
- Governance: keep a recurring review cycle so approved exceptions do not become permanent blind spots.
That operating model is especially important where unsanctioned SaaS has already issued tokens or touched shared identity infrastructure. In those cases, the issue is not only software sprawl, but trust sprawl, because a small local adoption can create enterprise-wide exposure. The OWASP Non-Human Identity Top 10 and NIST Cybersecurity Framework 2.0 both reinforce the need for discover, govern, detect, and respond capabilities rather than isolated approval steps.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 address the attack and risk surface, while CIS Controls v8 and NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| CIS Controls v8 | CIS Control 5 — Account Management | Shadow IT often creates unmanaged accounts and access paths. |
| CIS Control 6 — Access Control Management | Ownership must cover who can access and control unsanctioned tools. | |
| CIS Control 15 — Service Provider Management | Shadow IT commonly introduces third-party SaaS and integration risk. | |
| Recommendation — Inventory and govern accounts created through unsanctioned SaaS before they expand access. Restrict access to unsanctioned SaaS until it is reviewed and approved. Require service-provider review for SaaS that processes organisational data. | ||
| NIST CSF 2.0 | GV.OV-01 — Organizational Context | Shadow IT ownership depends on defining who is accountable for business and security context. |
| DE.CM-09 — External Service Provider Activity Monitoring | Discovery of shadow IT depends on monitoring third-party service use. | |
| GV.RM-01 — Risk Management Strategy | Shadow IT needs a shared risk strategy for review and exception handling. | |
| Recommendation — Define accountability for unsanctioned SaaS across business, IT, and security. Monitor external service use to detect unsanctioned SaaS adoption early. Set a risk strategy that defines how shadow IT exceptions are accepted or removed. | ||
| OWASP Non-Human Identity Top 10 | NHI-01 — Secrets Leakage | Unsanctioned SaaS can expose tokens and keys that function as identity-bearing material. |
| NHI-02 — Overprivileged Access | Shadow IT integrations often grant excessive permissions by default. | |
| Recommendation — Prevent SaaS sprawl from leaking tokens, API keys, and other secrets. Limit SaaS integrations to the minimum permissions needed. | ||
Practitioner Guidance
What to prioritise: assign a single operational owner for discovery and a single risk owner for decisions, but require both IT and security to stay involved. If ownership is vague, shadow IT tends to become a backlog item instead of a managed risk.
What to verify: confirm that the review process can see SaaS use outside procurement, not just sanctioned vendors. If your only control is purchase approval, you are measuring policy compliance rather than actual exposure.
Decision rule: if the tool handles corporate data, connects to SSO, or can issue API tokens, treat it as a governed service and not as a harmless productivity shortcut. At that point, ownership must include access review, data handling review, and exception tracking.
Practitioner takeaway: shadow IT is best owned as an enterprise visibility and remediation problem, with procurement as one input and security leadership as the force that keeps exceptions from becoming enduring blind spots.
