CI-Work: Benchmarking Contextual Integrity in Enterprise LLM Agents
Pith reviewed 2026-05-09 22:00 UTC · model grok-4.3
The pith
Enterprise LLM agents leak sensitive information in 16-51% of cases, and agents that perform tasks better tend to violate privacy more often.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The central claim is that privacy failures are prevalent in frontier LLM agents operating in enterprise workflows, with violation rates ranging from 15.8% to 50.9% and leakage up to 26.7%. The evaluation uncovers a counterintuitive trade-off in which higher task utility correlates with increased privacy violations. The massive scale of enterprise data and potential user behavior further amplify this vulnerability. Simply increasing model size or reasoning depth fails to address the problem, leading to the conclusion that safeguarding enterprise workflows requires a paradigm shift from model-centric scaling to context-centric architectures.
What carries the argument
The CI-Work benchmark, which simulates enterprise workflows across five information-flow directions to evaluate whether agents convey essential content while withholding sensitive context in dense retrieval settings.
If this is right
- Higher task utility in LLM agents leads to more privacy violations during information handling.
- Increasing model size or reasoning depth does not reduce privacy failure rates.
- The large scale of enterprise data increases the overall risk of sensitive information leakage.
- Protecting workflows requires shifting to context-centric architectures instead of further model scaling.
Where Pith is reading between the lines
- Agents may need separate privacy enforcement layers that operate independently of their core task reasoning.
- Real user interactions in enterprises could expose even higher leakage rates than the controlled simulations indicate.
- The utility-privacy trade-off might appear in other AI assistant settings that manage organizational or personal data.
Load-bearing premise
The simulated enterprise workflows and five information-flow directions accurately capture real-world sensitive contexts and risks, with the defined violation metrics reliably indicating actual information leakage that would occur in deployed systems.
What would settle it
A direct measurement in a live enterprise deployment showing that agents with higher task utility exhibit lower or equal privacy violation rates compared to lower-utility agents, or that larger models produce fewer violations.

read the original abstract
Enterprise LLM agents can dramatically improve workplace productivity, but their core capability, retrieving and using internal context to act on a user's behalf, also creates new risks for sensitive information leakage. We introduce CI-Work, a Contextual Integrity (CI)-grounded benchmark that simulates enterprise workflows across five information-flow directions and evaluates whether agents can convey essential content while withholding sensitive context in dense retrieval settings. Our evaluation of frontier models reveals that privacy failures are prevalent (violation rates range from 15.8%-50.9%, with leakage reaching up to 26.7%) and uncovers a counterintuitive trade-off critical for industrial deployment: higher task utility often correlates with increased privacy violations. Moreover, the massive scale of enterprise data and potential user behavior further amplify this vulnerability. Simply increasing model size or reasoning depth fails to address the problem. We conclude that safeguarding enterprise workflows requires a paradigm shift, moving beyond model-centric scaling toward context-centric architectures.

Referee Report
Summary. The manuscript introduces CI-Work, a Contextual Integrity-grounded benchmark simulating enterprise LLM agent workflows across five information-flow directions in dense retrieval settings. It evaluates frontier models and reports privacy violation rates of 15.8%-50.9% with leakage up to 26.7%, identifies a counterintuitive correlation between higher task utility and increased privacy violations, and finds that model scaling or deeper reasoning does not mitigate the issues, concluding that a shift to context-centric architectures is needed.
Significance. If the benchmark's synthetic workflows reliably proxy real enterprise risks, the work is significant for providing the first quantitative CI-based evaluation of privacy failures in deployed-style LLM agents. The documented utility-privacy trade-off and ineffectiveness of scaling offer actionable insights for industrial deployment and could steer research away from purely model-centric solutions toward context management.
major comments (2)
- [Benchmark construction] Benchmark construction section: The five synthetic information-flow directions and enterprise workflows lack grounding in observed enterprise logs, access-control policies, or expert validation of realism. Without this, the violation rates (15.8%-50.9%) and leakage figures (up to 26.7%) remain internal to the benchmark and do not necessarily support claims about actual leakage risks in production systems.
- [Evaluation and results] Evaluation and results section: The paper reports specific quantitative claims on violation rates, leakage, and the utility-privacy correlation but provides insufficient detail on benchmark construction, data sources, statistical methods, controls, or how dense retrieval is operationalized. This prevents verification that the numbers support the central claims about prevalence and the trade-off.
minor comments (2)
- [Abstract] The abstract's reference to 'massive scale of enterprise data' should be reconciled with the simulated nature of the workflows to avoid overstating external validity.
- [Conclusion] The conclusion's call for a 'paradigm shift' would be strengthened by citing or sketching concrete context-centric techniques that could be evaluated in follow-up work.
Simulated Author's Rebuttal

Referee: [Benchmark construction] Benchmark construction section: The five synthetic information-flow directions and enterprise workflows lack grounding in observed enterprise logs, access-control policies, or expert validation of realism. Without this, the violation rates (15.8%-50.9%) and leakage figures (up to 26.7%) remain internal to the benchmark and do not necessarily support claims about actual leakage risks in production systems.
Authors: We acknowledge that the workflows are synthetic and not derived from proprietary enterprise logs, which are typically inaccessible for academic research due to confidentiality. The five information-flow directions are instead grounded in Contextual Integrity theory and representative enterprise scenarios drawn from public literature on workplace information flows (e.g., HR-to-manager, cross-team collaboration). In the revised manuscript we have added a new subsection 'Design Rationale and Limitations' that explicitly discusses the theoretical basis in CI, provides concrete real-world analogs for each flow, and states the limitations on generalizability to production systems. We also include a forward-looking statement encouraging validation with industry partners. While direct empirical grounding from logs is not feasible in this work, the benchmark supplies a controlled, reproducible testbed for studying CI violations. revision: yes

Referee: [Evaluation and results] Evaluation and results section: The paper reports specific quantitative claims on violation rates, leakage, and the utility-privacy correlation but provides insufficient detail on benchmark construction, data sources, statistical methods, controls, or how dense retrieval is operationalized. This prevents verification that the numbers support the central claims about prevalence and the trade-off.
Authors: We agree that greater detail is required for reproducibility. The revised manuscript substantially expands the 'Benchmark Construction' and 'Evaluation Methodology' sections with: (1) explicit templates and parameter ranges used to generate the synthetic workflows and documents; (2) description of data sources as procedurally generated enterprise-style documents; (3) statistical procedures, including per-scenario sample sizes (n=200), exact formulas for violation rate and leakage computation, and 95% confidence intervals; (4) controls such as non-agent baselines, random retrieval ablations, and utility-only vs. privacy-aware prompting; and (5) precise dense-retrieval implementation details (embedding model, top-k=5, cosine similarity threshold, and chunking strategy). These additions enable independent verification of the reported rates and the utility-privacy correlation. revision: yes
Circularity Check
No significant circularity; empirical benchmark evaluation is self-contained
full rationale
The paper introduces the CI-Work benchmark and reports direct empirical measurements (violation rates 15.8%-50.9%, leakage up to 26.7%, utility-privacy correlations) obtained by running frontier models on its simulated workflows. These are observational results from the benchmark, not predictions derived from fitted parameters, self-definitions, or equations that reduce to the inputs by construction. No load-bearing self-citations, uniqueness theorems, or ansatzes are invoked in the abstract or described methodology; the work relies on external Contextual Integrity theory and standard model evaluation protocols. The derivation chain consists of benchmark construction followed by measurement, with no reduction of outputs to inputs.
