Protecting Sensitive Data in the Age of Generative AI: Risks, Challenges, and Solutions
Generative AI tools like ChatGPT, Copilot, and Claude are transforming the workplace by enabling employees to work faster and smarter. These tools can draft reports, summarize complex data, and even assist with problem-solving—all in a matter of seconds. However, this convenience comes at a cost. A recent report by Harmonic revealed that 8.5% of employee prompts to these tools include sensitive data. This includes customer information (46%), employee personally identifiable information (PII) (27%), and legal or financial details (15%). Even more alarming, over half of these leaks (54%) occur on free-tier AI platforms that use user queries to train their models.
For enterprises, this is a ticking time bomb. Sensitive data leaks through generative AI tools pose serious risks to data privacy, security, and regulatory compliance. As generative AI becomes more prevalent in the workplace, organizations must act swiftly to mitigate these risks while still reaping the benefits of AI-powered productivity.
In this blog post, we’ll explore why employees are tempted to use sensitive data when prompting large language models (LLMs), the ramifications of doing so, and actionable steps companies can take to prevent this practice. Finally, we’ll discuss how Kiteworks’ AI Data Gateway provides an ideal solution for safeguarding sensitive data in this new era of AI-driven innovation.
Why Employees Use Sensitive Data When Prompting LLMs
Generative AI tools have become indispensable for many employees because they promise one thing: efficiency. In today’s fast-paced business environment, employees are under constant pressure to deliver results quickly and accurately. Generative AI offers a shortcut—one that’s often too tempting to resist.
1. Save Time
Employees frequently turn to LLMs to save time on repetitive or labor-intensive tasks. For example, customer service representatives might input customer billing information into an LLM to draft personalized responses or troubleshoot issues more efficiently. Similarly, HR professionals may use payroll data to generate reports or summaries quickly.
2. Boost Efficiency
Generative AI excels at synthesizing large datasets and presenting insights in a digestible format. Employees working with insurance claims or legal documents may upload sensitive information into an LLM to generate summaries or identify patterns that would otherwise take hours—or even days—to uncover manually.
3. Solve Complex Problems
When faced with technical challenges, employees may share security configurations or incident reports with an LLM to receive actionable recommendations. While this can be incredibly helpful for troubleshooting, it also exposes critical security details that could be exploited if leaked.
4. Lack of Alternatives
In many cases, employees resort to free-tier generative AI tools because enterprise-approved alternatives are either unavailable or not user-friendly. This lack of accessible tools pushes employees toward shadow IT practices, where they use unauthorized apps without IT oversight.
While these motivations are understandable from an employee’s perspective, they create significant risks for organizations—risks that must be addressed proactively.
Key Takeaways
-
Generative AI Poses Data Privacy Risks
Research revealed a significant portion (8.5%) of employee prompts to AI tools contain sensitive data, including customer information, employee PII, and financial/legal details.
-
Employees Use AI for Efficiency, Often at the Cost of Security
Employees turn to AI to save time, boost productivity, and solve complex problems, but they are frequently unaware that the sensitive data they upload into LLMs is stored and referenceable for future queries and tasks.
-
Data Leaks Can Lead to Severe Consequences
Companies risk data privacy violations (GDPR, HIPAA, CCPA, etc.), security breaches, and reputational damage when their sensitive data is ingested by large language models (LLMs).
-
Organizations Must Implement Proactive Safeguards
Strategies include employee training, AI usage monitoring, DLP software, and enterprise-sanctioned AI tools. Access control mechanisms and secure AI platforms can further help mitigate exposure.

Kiteworks’ AI Data Gateway Provides a Robust Security Solution
Features like controlled access, encryption, audit trails, and regulatory compliance support help enterprises securely leverage AI while minimizing data leakage risks.
Ramifications of Sharing Sensitive Data with LLMs
The consequences of sharing sensitive data with generative AI tools extend far beyond the immediate workplace benefits. Organizations face a host of risks that can jeopardize their reputation, financial stability, and legal standing.
1. Data Privacy Risks
Free-tier generative AI platforms often use user queries for model training unless explicitly prohibited by enterprise contracts. Once sensitive information is uploaded into these systems, it becomes part of the model’s training dataset and is effectively out of the organization’s control. This creates a significant risk of exposing private customer or employee information.
2. Data Security Vulnerabilities
Security-related prompts—such as penetration test results or network configurations—are particularly dangerous if leaked through generative AI tools. Cybercriminals could exploit this information to identify vulnerabilities and launch targeted attacks against the organization.
3. Regulatory Compliance Issues
Sharing sensitive data with LLMs can violate various data protection laws and regulations, such as GDPR (General Data Protection Regulation), HIPAA (Health Insurance Portability and Accountability Act), or CCPA (California Consumer Privacy Act). For example:
- General Data Protection Regulation: Uploading EU citizens’ personal data without proper safeguards could result in substantial GDPR fines.
- Healthcare Insurance Portability and Accountability Act: Sharing patient health information with an LLM could breach HIPAA privacy rules.
- California Consumer Privacy Act: Unauthorized disclosure of California residents’ personal data is a CCPA violation, potentially leading to lawsuits or penalties.
Additionally, trade secrets lose their legal protections if they are disclosed through generative AI systems—potentially invalidating intellectual property rights.
4. Reputational Damage
A high-profile data breach stemming from careless use of generative AI tools could erode customer trust and damage the company’s brand reputation. In today’s digital age, such incidents often lead to public backlash and long-term reputational harm.
5. Bad Data Ingestion Risks
The risks aren’t limited to sensitive data leaving the organization; flawed or inaccurate information generated by LLMs can also enter the enterprise’s workflows. If employees rely on incorrect insights from generative AI tools for decision-making, it could lead to costly mistakes or compliance violations.
How Companies Can Prevent Generative AI Data Leaks
To mitigate these risks, organizations must adopt a comprehensive approach that combines education, technology, and policy enforcement. Let’s take a closer look at each of these strategies below.
1. Conduct Training & Awareness Programs
Educating employees about the risks associated with sharing sensitive data is essential:
- Train employees on how generative AI works and why uploading sensitive information is risky.
- Teach query phrasing strategies that allow employees to get useful results without revealing protected information.
- Foster a culture of accountability where employees understand their role in safeguarding organizational data.
2. Monitor File Access & Usage
Implement systems that monitor who accesses sensitive files and how they are used:
- Use access control mechanisms to restrict file usage based on roles.
- Deploy monitoring tools that flag unusual activity involving sensitive files or systems.
3. Invest in Technology Solutions
Invest in technology solutions designed to prevent unauthorized uploads:
- Deploy Data Loss Prevention (DLP) software that blocks attempts to upload sensitive files to external platforms.
- Use secure enterprise-grade generative AI tools that meet regulatory requirements for privacy and compliance.
- Invest in next-gen DRM capabilities to enable sharing of sensitive data but prevent the downloading or forwarding of that data.
- Implement solutions like Kiteworks’ AI Data Gateway for additional safeguards (discussed below).
4. Enterprise-Sanctioned Tools
Provide employees with secure alternatives to free-tier generative AI platforms:
- Ensure enterprise-approved tools are user-friendly and accessible.
- Regularly review and update enterprise tools to meet evolving business needs and technological advancements.
