TL;DR: Data classification is most effective as a repeatable process that combines content, ownership, and movement context, and Orion argues that large language models plus identity signals can reduce false positives while surfacing real exposures. The shift matters because static pattern rules miss how data is actually being handled, which is where governance breaks down.
At a glance
What this is: This is a guide to running data classification as an ongoing security process, with the key finding that content-only rules fail when data moves across users, apps, and AI tools.
Why it matters: It matters to IAM and security teams because classification increasingly depends on identity, destination, and handling context, not just what the file contains.
By the numbers:
- Only 5.7% of organisations have full visibility into their service accounts.
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools.
- 79% of organisations have experienced secrets leaks, and 77% of those incidents resulted in tangible damage.

Context
Data classification is a governance control, not a one-off labelling exercise. The hard part is keeping the label meaningful when data moves into email, SaaS applications, vendor workflows, and AI tools, where static pattern rules often lose context. For identity and security teams, the real question is whether the control follows the data or stops at the first scan.
The article argues that classification should combine content, ownership, and movement context, with automation handling volume and people handling edge cases. That framing is relevant to IAM and NHI programmes because access, destination, and delegated use increasingly determine whether data handling is acceptable, especially when service accounts, third-party access, or AI assistants are involved. In practice, that makes classification a living control rather than a compliance artefact.
Key questions
A: Security teams should combine automated classifiers with business context, so detection reflects what matters to the organisation rather than generic data categories. The goal is to improve precision, reduce false positives and false negatives, and keep policies consistent as data spreads across repositories, collaboration tools, and analytics platforms. Good classification also supports faster governance decisions and cleaner downstream enforcement.
Q: Why do static pattern rules fail for sensitive data classification?
A: Static rules can recognise patterns, but they cannot tell whether the transfer is routine, delegated, or out of policy. That creates false positives on harmless files and blind spots on risky movement. When classification ignores context, teams end up chasing alerts instead of controlling exposure.
Q: What are the signs that a data classification process is breaking down?
A: Common warning signs include too many manual exceptions, labels that do not change access or routing, stale classifications after business changes, and users treating labels as decoration. If the process does not survive copy, paste, and sharing workflows, the control has lost operational credibility.
Q: Should organisations classify data before or after adding DLP and AI controls?
A: Classify first, but do not stop there. DLP and AI controls need a sensitivity model they can enforce, otherwise they only see isolated events. The right sequence is to define levels and ownership, then connect those levels to the controls that govern movement and use.
Technical breakdown
Why content-only classification fails in motion
Content-only classification relies on patterns such as keywords, regexes, or file fingerprints to decide sensitivity. That works for obvious cases, but it breaks when context changes. A file can contain sensitive data and still be low risk in one workflow, while a seemingly ordinary export becomes dangerous when it is copied into the wrong destination or handled by the wrong identity. The article’s core technical point is that classification must understand both the content and the movement context, otherwise it produces either false positives or blind spots. Practical systems need to treat identity, destination, and expected use as part of the verdict, not as post-processing metadata.
Practical implication: supplement pattern rules with identity and destination signals before deciding how data is handled.
How LLM-assisted classification changes the workflow
Large language models can classify data by reading meaning, not only matching patterns. That matters because labels are often about intent and business context, not just file contents. In the article’s model, the LLM proposes a verdict while identity and environment signals determine whether the movement is normal, risky, or out of policy. This is less about automation replacing people and more about automation scaling judgment. The useful technical shift is from fixed rulebooks that age quickly to contextual reasoning that can adapt as data moves through new systems, including AI assistants and third-party workflows.
Practical implication: use LLM-assisted triage for volume, but require human review for edge cases and policy exceptions.
What makes a classification policy enforceable
A classification policy only works when the labels are tied to handling rules. The article describes the policy as a short rulebook that defines levels, ownership, and what each label means in practice. That is the difference between a label that looks tidy on paper and one that changes access, routing, encryption, or sharing behaviour. If the control does not affect how data can move, users will treat it as documentation. For practitioners, the technical requirement is consistency across systems so the same label produces the same handling outcome wherever the data appears.
Practical implication: bind each classification level to concrete handling rules across storage, sharing, and downstream workflows.
Threat narrative
Attacker objective: The objective is to move sensitive data into an unapproved workflow without triggering the controls that should have constrained its use.
- Entry occurs when sensitive data is copied into email, SaaS tools, or AI assistants without the surrounding identity and destination context being evaluated.
- Escalation follows when static pattern rules misclassify the movement, allowing an inappropriate recipient or workflow to process data as if it were low risk.
- Impact is the exposure of information that should have been constrained by handling rules, with false positives distracting teams from the real leakage path.
NHI Mgmt Group analysis
Data classification is becoming a contextual control, not a label management exercise. Static tagging cannot keep pace with modern data movement across SaaS, email, collaboration tools, and AI assistants. The article’s strongest contribution is that it treats classification as a repeated governance process that must survive real-world use. For practitioners, that means the label only matters if it continues to shape handling decisions after the file moves.
Identity signals are now part of classification governance. Once access, ownership, and destination determine whether a transfer is acceptable, classification is no longer purely a data-management task. That makes the boundary with IAM and NHI governance explicit, especially where service accounts, third-party integrations, and AI tools move data on behalf of people. The practitioner implication is to align classification logic with who or what is moving the data, not only what the data contains.
Context-aware classification reduces governance debt. A process that relies on static pattern libraries accumulates exceptions, manual overrides, and noisy alerts until users stop trusting the control. The article’s LLM plus identity-signal approach points to a named concept we would call classification context debt: the growing gap between labels and actual handling conditions. Teams should treat closing that gap as a governance priority, not a tuning exercise.
Classification and AI governance are converging. The example of data being pasted into an AI assistant shows that information control now extends into model-facing workflows. That introduces a new governance question: whether data classification can still hold once content leaves traditional repositories and enters generative interfaces. Practitioners should assume AI tools are part of the data movement layer and govern them accordingly.
Ownership is the control that makes classification durable. The article correctly notes that classification fails when it becomes nobody’s job. That is a familiar governance pattern across identity programmes too, where lifecycle controls fail when accountability is diffuse. For security leaders, the action is to assign ownership for labels, for handling rules, and for reclassification triggers so the process survives organisational churn.
What this signals
Classification is starting to behave like an identity decision. Once data handling depends on who moved the file, where it went, and what system touched it, classification and IAM stop being separate conversations. That is especially relevant where service accounts, API-driven workflows, and AI assistants move information at machine speed. Teams should expect more pressure to connect data controls to identity telemetry rather than treat them as parallel programmes.
The operational signal is that static policy libraries will not keep up with modern movement patterns. Organisations that cannot connect labels to enforcement will accumulate exceptions and noisy alerts, while those that tie classification to identity and destination will get better signal. For teams already working on delegated access and machine identity governance, this is another reason to unify data movement oversight with access control and audit trails.
Classification context debt: the gap between a data label and the real conditions under which the data is used, moved, or shared. As organisations add AI tools, third-party collaboration, and machine-driven workflows, this debt grows faster than manual review can absorb. The practical response is to make reclassification event-driven and to tie it to identity changes, workflow changes, and approved destinations.
For practitioners
- Define classification levels as handling rules Tie each sensitivity level to explicit rules for storage, sharing, encryption, and approved destinations so the label changes behaviour, not just metadata.
- Add identity and destination signals to verdicts Require classification systems to consider who is moving the data, where it is going, and whether that destination matches the expected business context.
- Review labels on a fixed and event-driven cycle Reclassify when the business changes, when a new SaaS or AI tool is introduced, or when data starts moving in ways the original label did not anticipate.
- Treat AI assistants as part of the data control surface Block or review sensitive transfers into AI tools unless the workflow, identity, and handling rule are explicitly approved for that data class.
- Assign accountable owners for each data class Make a business owner responsible for the label, a steward responsible for day-to-day accuracy, and security responsible for enforcement.
Key takeaways
- Data classification fails when it stops at the label and ignores the identity and destination context around movement.
- LLM-assisted classification can scale judgment, but only if human ownership and enforcement still anchor the process.
- For IAM and NHI teams, the real governance shift is to treat classification as part of the access and data-movement control plane.

Key terms
- Data Classification Policy: A data classification policy is the formal rule set that defines how an organisation labels, handles, and protects information based on sensitivity and business impact. It links data categories to ownership, access, retention, and security controls so handling is consistent across systems and teams.
- Context-aware classification: Context-aware classification uses surrounding document meaning, not just keywords, to determine what a file or record represents. It reduces false positives and helps security teams distinguish incidental references from content that is genuinely high consequence.
- Classification Context Debt: Classification context debt is the gap that appears when a label no longer reflects the real conditions under which data is handled. It grows when business processes change faster than review cycles, creating stale labels, noisy exceptions, and blind spots in downstream controls.
- Sensitive Data Movement: Sensitive data movement is the transfer, copying, sharing, upload, or export of protected information across applications and environments. In browser-heavy workflows, it is the event DLP tries to govern because that is where leakage often occurs.
