Transitive AI is AI capability that enters an environment through third-party software, bundled components, or dependencies rather than direct adoption. It matters because the organisation may inherit models, assistants, or agents without deliberate review, ownership, or governance enrollment.
Expanded Definition
Transitive AI describes AI functionality that enters an organisation indirectly, such as through SaaS products, plugins, packaged libraries, managed workflows, or other third-party dependencies. The key issue is not whether the organisation bought an AI platform outright, but whether AI behavior, data processing, or agentic execution is present somewhere in the supply chain and operating with inherited trust.
In NHI and IAM terms, transitive AI is a governance problem because the organisation may inherit model calls, prompt handling, tool access, or autonomous actions without an explicit owner, risk review, or lifecycle record. That makes it different from sanctioned internal AI deployments, where identity, access, logging, and approval can be assigned directly. Definitions vary across vendors, but the operational concern is consistent: AI can arrive embedded in software long before it is formally enrolled into security controls. NIST’s NIST Cybersecurity Framework 2.0 is useful here because it frames governance and supply chain accountability as core security functions, not optional add-ons.
The most common misapplication is assuming a vendor feature is “just automation,” which occurs when AI-enabled dependencies are approved as ordinary software and never reviewed as a distinct identity and data-risk surface.
Examples and Use Cases
Implementing controls for transitive AI rigorously often introduces procurement and integration friction, requiring organisations to weigh faster adoption against the cost of discovery, inventory, and approval checks.
- A customer support platform adds an embedded assistant that can summarise tickets and suggest replies, but the security team never reviews the assistant’s data retention or tool permissions.
- A code dependency introduces an AI-backed refactoring feature, creating hidden prompt and telemetry flows that are not captured in the application’s original architecture review.
- A workflow automation product routes messages through an agentic component that can trigger actions in downstream systems, yet the organisation treats it as a standard SaaS integration.
- A managed collaboration tool adds document classification or search augmentation powered by third-party AI, and sensitive content is processed without a clear governance enrollment path.
- The exposure pattern seen in the DeepSeek breach illustrates how AI features and surrounding data stores can become operationally relevant even when adoption was not intentionally scoped as an internal AI program.
In practice, transitive AI is often easiest to spot by asking whether an external component can read, transform, or act on organisational data in ways that were never explicitly approved. That question aligns with broader supply-chain guidance in the NIST Cybersecurity Framework 2.0, even when the component is marketed as a productivity feature rather than an AI system.
Why It Matters in NHI Security
Transitive AI matters because it can create unmanaged identity pathways for models, assistants, and agents that operate inside trusted software boundaries. Once those components can call APIs, access documents, or generate actions, they begin to behave like NHIs even if nobody assigned them an owner, secrets boundary, or change-control record. That makes incident response harder, because security teams may discover an AI execution path only after abnormal data movement, unexpected API usage, or an upstream vendor disclosure.
NHIMG research shows how quickly AI-related credential abuse can unfold: in the LLMjacking research, publicly exposed AWS credentials were targeted by attackers in an average of 17 minutes. That timing is especially relevant when transitive AI depends on inherited secrets, delegated access, or opaque third-party integrations. The same research stream and the DeepSeek breach both show that AI exposure is often inseparable from secret sprawl, hidden dependencies, and incomplete ownership.
Organisations typically encounter the consequences only after a vendor incident, a data leak, or an unexpected agent action, at which point transitive AI 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 and OWASP Agentic AI Top 10 address the attack and risk surface, while NIST CSF 2.0 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Transitive AI creates hidden non-human identities and inherited access paths. |
| NIST CSF 2.0 | GV.SC-1 | Supply chain governance covers third-party AI features and embedded dependencies. |
| OWASP Agentic AI Top 10 | A1 | Agentic behavior can arrive through dependencies without explicit approval or controls. |
Track vendor AI features as supply-chain assets and require risk review before deployment.
