An unsanctioned app is a software service used without formal approval from IT or security. These tools may solve business needs, but they also bypass standard controls for onboarding, offboarding, monitoring, and compliance. Organisations often lose visibility into where data is stored, who can access it, and whether the service is properly governed.
Expanded Definition
An unsanctioned app is a software service adopted outside formal IT or security approval, often because it is fast, convenient, or fills a workflow gap. In NHI and IAM contexts, the concern is not simply that the tool is unofficial, but that its identity, access paths, and data handling are usually invisible to governance processes.
Definitions vary across vendors and security teams: some use shadow IT to mean any unapproved application, while others reserve unsanctioned app for SaaS tools that employees or teams actively use without registration. In practice, the risk comes from bypassing onboarding, offboarding, monitoring, and retention controls, which can leave accounts, API keys, and data permissions unmanaged. That makes unsanctioned apps especially relevant to non-human identity security when they create forgotten integrations, orphaned tokens, or credentials stored outside approved systems. NIST Cybersecurity Framework 2.0 is useful here because it frames the need for asset visibility, access control, and risk governance across the environment.
The most common misapplication is treating unsanctioned apps as a procurement issue only, which occurs when security teams focus on approved vendor lists while ignoring how employees actually exchange data through ungoverned services.
Examples and Use Cases
Implementing control over unsanctioned apps rigorously often introduces friction for business teams, requiring organisations to weigh speed and local productivity against visibility, data protection, and identity governance.
- A marketing team syncs customer lists into an unsanctioned design or collaboration platform, creating a data residency and access review gap that security never sees until an audit or incident.
- A developer connects a cloud automation tool to production systems with a personal API key, then leaves the company and no one remembers to revoke the integration.
- A finance group uses an unofficial file-sharing app for vendor statements, bypassing logging and retention rules that would normally apply under approved services.
- An operations team adopts a no-code workflow service to move alerts between systems, but the service account behind it is never inventoried or rotated.
These patterns mirror broader NHI problems described in the Ultimate Guide to NHIs, where hidden service access and weak lifecycle control create lasting exposure. For governance comparison, the NIST Cybersecurity Framework 2.0 reinforces the need to identify assets, manage access, and monitor for risk drift even when tools arrive outside formal intake.
Why It Matters in NHI Security
Unsanctioned apps matter because they often become the easiest place for secrets, delegated access, and third-party integrations to spread beyond control. Once a team has uploaded tokens, connected service accounts, or granted OAuth consent to an unapproved service, the organisation may lose track of who can reach sensitive systems and whether those credentials are still valid. That is why unsanctioned apps are tightly linked to secret sprawl, excessive privilege, and offboarding failure.
NHI Mgmt Group reports that only 5.7% of organisations have full visibility into their service accounts, and that gap becomes worse when app adoption happens outside approved pathways. The same visibility problem appears in the Ultimate Guide to NHIs, which also shows that 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools. When unsanctioned apps become the real workflow layer, governance tools no longer reflect operational reality. Organisations typically encounter the consequence only after a breach, audit failure, or business interruption, at which point unsanctioned app control becomes operationally unavoidable to address.
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, OWASP Agentic AI Top 10 and CSA MAESTRO address the attack and risk surface, while NIST CSF 2.0 and NIST Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | ID.AM | Unsanctioned apps create unmanaged assets that must be identified and tracked. |
| OWASP Non-Human Identity Top 10 | NHI-01 | Unapproved apps often hide service accounts, tokens, and other non-human identities. |
| OWASP Agentic AI Top 10 | A-01 | Agentic and automated app use can bypass approval and monitoring controls. |
| NIST Zero Trust (SP 800-207) | JIT access | Unsanctioned apps undermine zero trust when standing access is granted outside policy. |
| CSA MAESTRO | IAM-1 | MAESTRO addresses identity and access governance for AI-connected workflows and tools. |
Restrict autonomous tool use to approved services with logging, policy checks, and revocation paths.
