Closing the Gap: A User Study on the Real-world Usefulness of AI-powered Vulnerability Detection & Repair in the IDE
Security vulnerabilities impose significant costs and risks. Deep learning models show promise for detection and repair, but their practical usefulness in real-world development settings remains largely unexplored. This analysis presents findings from the first empirical study of an AI-powered vulnerability detection and fix tool, DEEPVULGUARD, used by professional developers on their own projects.
Executive Impact
Our comprehensive study with 17 professional software developers at Microsoft, utilizing an IDE-integrated tool (DEEPVULGUARD) with state-of-the-art AI models (CodeBERT, GPT-4), revealed critical insights into the practical deployment of AI for vulnerability management. While the tool showed promising benchmark performance and user interest (59% for future use), real-world application faced significant hurdles. Key issues included a high rate of false positives (leading to 30% user trust degradation), non-customized and often inapplicable fixes, and workflow disruptions due to manual scanning. However, features like confidence scores, natural-language explanations, and interactive chat demonstrated potential for improving usability and effectiveness, highlighting actionable pathways for future development and deployment of such AI tools.

Users lost trust due to false positives
In real-world deployment, the tool exhibited a higher false positive rate than benchmark tests, primarily due to missing contextual information (e.g., inter-procedural relationships) and language mismatches between training data (Python) and real projects (C#/TypeScript). Missing context alone accounted for 51% of false positives, with incorrect pattern recognition contributing 31%. This highlights the critical need for AI models to understand broader program context beyond isolated code snippets.

Detection Precision on SVEN benchmark
While DEEPVULGUARD achieved strong benchmark results with 80% precision and 32% recall on the SVEN dataset, its performance in a practical, diverse enterprise environment highlighted a significant gap. Developers tolerate up to 20% false positives, a threshold met on benchmarks but often exceeded in practice, indicating that current evaluation metrics may not fully capture real-world applicability.

of fixes not customized to codebase
Case Study: Non-Customized Fixes
A proposed fix for an SQL injection in a TypeScript endpoint involved generating a new sanitizeInput function. However, the developer preferred a simpler validation (e.g., checking if an ID is numeric) or reusing existing project-specific sanitization routines. This illustrates that functionally correct fixes are often rejected if they do not align with the project's existing architecture, style, or common utility functions, demanding significant manual overhaul.
Impact: Reduces developer adoption and increases manual rework despite AI-generated suggestions.

Correct fixes on Vul4J dataset
Evaluation on the Vul4J dataset showed only 13% of suggested fixes were correct, with an additional 8% being partial (resolving the issue but breaking other tests). A significant portion of fixes were problematic: 21% did not address the vulnerability, 17% incorrectly inserted code (syntax/indentation errors), 8% broke functionality, and 8% were placeholders rather than functional solutions. This underscores the need for AI-generated fixes to be robust, context-aware, and seamlessly integrable.
Interactive Chat Improves Fix Applicability
The interactive chat feature proved highly valuable, allowing developers to iterate on fix suggestions. Users could guide the AI towards their preferred approach, specify style guidelines, and refine fixes, ultimately leading to more applicable solutions. This conversational capability hints at a promising direction for overcoming the 'non-customized fix' challenge and enhancing developer satisfaction with AI-powered repair.

Workflow Disruption due to Manual Scans
Over two-thirds of participants (65%) reported that manually triggering scans significantly disrupted their workflow. Developers expressed a strong preference for tools that operate in the background, continuously scanning code during editing, or integrating with build/commit hooks. This highlights that for AI tools to be truly useful, they must become seamless parts of existing development pipelines rather than imposing additional manual steps.
Explanations & Confidence Scores: Value vs. Clarity
Vulnerability explanations were generally appreciated, with 35% finding them understandable and helpful. However, 42% found them too verbose, and 11% too broad or inconsistent, preferring concise examples or visual annotations over 'walls of text'. Confidence scores were widely used to rank issues (44%), but their meaning was often unclear (39%), and high-confidence false positives severely eroded trust (11%), suggesting a need to integrate severity scores and clarify output.
Incomplete Localization Hinders Trust
While localization was helpful for identifying vulnerability locations (21%), 58% of feedback indicated it was incomplete, often highlighting only a part of the code structure rather than the root cause or source of input. This incompleteness led to user confusion and eroded trust, with developers questioning the accuracy of alerts that didn't align with semantic boundaries or the full problem scope.

Practical Recommendations for AI Tool Deployment
Based on our study, we propose several key recommendations for the practical evaluation and deployment of AI detection and fix models:
1. Context-aware Models: Develop benchmarks and models that incorporate calling context and runtime environment to reduce false positives and improve real-world accuracy.
2. Consistent AI Outputs: Ensure seamless integration and consistency across outputs from different AI models (detection, explanation, fix) to avoid confusing users and eroding trust.
3. Enhanced Explanations: Guide LLMs to generate concise, actionable explanations with visual annotations and integrate severity scores with confidence scores for better prioritization.
4. Customizable Fixes: Empower interactive chat to guide AI-generated fixes, allowing developers to specify preferences for existing libraries, coding styles, and specific approaches for better integration into their codebase.
5. Seamless Workflow Integration: Prioritize background scanning, and provide build/commit hook integrations to avoid disrupting developer workflow.
