TL;DR: LLM workflows widen exposure through data leakage, hallucinations, legal uncertainty and misuse, Lookout says, as cloud-hosted systems move data outside organisational control. Governance has to extend across retrieval, identity, tool use and output review.
Editorial analysis by NHI Mgmt Group, based on content published by Lookout: “What Is a Large Language Model (LLM)?”.
Key questions
Q: Why do LLM integrations create new security risk even when the model is well behaved?
A: Because the risk often sits outside the model.
Q: What signs show that a workflow is trusting LLM output too much?
A: Warning signs include prompts that can trigger downstream actions, responses that are executed without review, and controls that assume the model will always refuse unsafe requests.
Q: How should organisations govern LLMs that support operational decisions?
A: Treat the model as part of a governed workflow, not an isolated tool.
Practitioner guidance
- Define LLM trust boundaries Map every place the model can receive prompts, retrieve data, call tools or write outputs into another system.
- Classify sensitive training and fine-tuning data Restrict which documents, tickets, logs and transcripts can be used to train or fine-tune models, and apply retention and redaction rules before content enters the pipeline.
- Apply identity controls to AI integrations Use least privilege for APIs, connectors and automated workflows that allow LLMs to act on behalf of users or services, and log each action with a clear owning identity.
Bottom line: LLM risk is not limited to model accuracy. It also includes data leakage, misuse through integrations and operational trust in generated output.

LLM governance debt is now an identity problem as much as an AI problem: once models are connected to enterprise data and workflows, the governance burden shifts from model quality to control of access, retrieval and execution. That means prompt entry, tool invocation and data exposure all need explicit ownership. Organisations that treat LLMs as standalone applications will miss the control plane where the real risk sits.
A few things that frame the scale:
- AI-related credential leaks surged 81.5% year-over-year in 2025, with the surrounding AI infrastructure leaking 5x faster than core LLM providers, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: What is the difference between traditional application security and AI governance for LLMs?
A: Traditional application security assumes predictable inputs, stable logic, and clearly bounded authorisation paths. AI governance has to account for stochastic output, prompt-level influence, retrieval-based context, and the possibility that the model will reinterpret instructions in ways normal application controls do not anticipate.
