Shadow AI Applications Leak Sensitive Data
As employees experiment with new GenAI tools and prompts, your proprietary data may be exposed.
Why Are Unauthorized GenAI Apps Risky?
Shadow AI Applications Lead to Data Loss
Generative AI (GenAI) is rapidly transforming how employees work: enabling automation, assisting with content generation, and performing data analysis at unprecedented speeds. However, as employees explore new AI-powered tools, they may inadvertently expose proprietary and sensitive corporate data.
The rise of Shadow AI—unauthorized generative and other AI applications used without IT or security approval—presents significant risks, from data loss and regulatory violations, to new forms of insider threats. Obsidian Security has observed +50% of organizations have at least one shadow AI application.
Many GenAI applications require users to input text-based prompts, which can include sensitive information such as customer data, financial records, intellectual property, or proprietary strategies. When employees interact with these tools without proper safeguards, they risk exposing confidential information to external AI models that retain, analyze, or repurpose the data, creating long-term security vulnerabilities.
What is Shadow AI?
Shadow AI refers to the unauthorized use of generative AI applications by employees without IT or security oversight. These tools include AI-powered chatbots like ChatGPT and Anthropic, content generators, coding assistants, and image-processing platforms. While many of these applications offer powerful capabilities, their uncontrolled usage in corporate environments can lead to unintended security, compliance, and financial risks.
Why Employees Use Shadow AI
1. Increased Productivity
Employees turn to GenAI tools to automate tasks, generate reports, write code, and enhance decision-making.
2. Lack of Corporate AI Policies
Without clear guidelines on AI usage, employees experiment with various applications without understanding the risks.
3. Accessibility and Ease of Use
AI applications are readily available online, requiring no installation or IT approval.
4. Personal AI Habits Crossing Over to Work
Many users become familiar with AI tools in personal settings and then apply them to workplace tasks without considering security implications.
Risks of Unauthorized GenAI Apps
1. Data Loss and Exposure
One of the biggest risks of Shadow AI is data loss. Many generative AI tools store user inputs on platform memory to improve their models, meaning the AI provider could retain and access sensitive corporate data. This risk includes:
- Unintentional Data Sharing: Employees may input confidential information without realizing it is being logged and stored.
- AI Training on Proprietary Data: Some GenAI tools use submitted content to train future models, potentially exposing sensitive business strategies, source code, or personal data to other users.
- Lack of Data Deletion Guarantees: Unlike corporate-controlled applications, unauthorized AI tools may not allow organizations to delete submitted information, creating long-term security concerns.
2. Regulatory and Compliance Violations
Industries with strict data protection laws, like financial services, require organizations to control how data is processed, stored, and shared. Shadow AI applications can violate these regulations by:
- Transmitting Data Outside Approved Jurisdictions: Many AI providers store data in locations that may not comply with regional privacy laws.
- Failing to Meet Industry-Specific Compliance Requirements: Unauthorized AI tools may not be designed with financial, healthcare, or government compliance standards in mind.
- Lack of Audit Trails: Without visibility into AI interactions, security teams cannot track or report on data usage, increasing the risk of regulatory penalties.
3. Intellectual Property (IP) Risks
Organizations risk losing ownership of proprietary information if it is fed into GenAI applications that claim usage rights over user-submitted data. This can lead to:
- Competitive Exposure: Confidential business strategies, software code, or research insights may unintentionally become part of a publicly accessible AI model.
- Loss of Trade Secrets: Once proprietary data is used to train an AI model, it may no longer be exclusive to the organization, leading to loss of competitive advantage.
- Legal Disputes Over AI-Generated Content: Unclear AI content ownership policies can result in disputes over generated intellectual property.
4. Shadow AI Increases Cybersecurity Vulnerabilities
Unauthorized AI applications grow the attack surface and introduce new attack vectors for cybercriminals to exploit:
- Phishing and Social Engineering: AI can be used to create highly convincing phishing ploys, misleading employees into clicking malicious links or sharing credentials.
- Weak Security: Many new consumer-grade AI tools lack enterprise-grade security controls, increasing the risk of account takeovers.
5. Financial and Operational Costs
Shadow AI can lead to unexpected costs due to:
- Overlapping AI Subscriptions: Untracked AI tool usage results in redundant expenditures on multiple similar applications.
- Incident Response Costs: If an AI-related data breach occurs, organizations may face costly forensic investigations, legal fees, and regulatory fines.
Mitigating the Risks of Shadow AI
1. Implement AI Security and Governance Policies
Organizations must define clear policies on GenAI usage, including:
- Create a List of Approved Apps: Define which AI applications are sanctioned or prohibited for use.
- Sensitive Data Handling: Set strict guidelines for how employees can interact with AI tools when sensitive or proprietary data is involved.
- Role-Based Access Controls: Ensure access to AI tools is limited based on job function, reducing unnecessary exposure.
2. Deploy AI Monitoring and Security Controls
Organizations should implement security policies around:
- AI Tool Discovery: Gain total visibility into the AI tool landscape and determine authorized usage of apps that may be outside the IdP
- Threat Detection: Spot unauthorized access to AI systems, suspicious activity, and other anomalies that may indicate compromise or insider risk.
3. Educate Employees on AI Risks
Conduct regular security awareness training to ensure employees understand responsible AI usage:
- Safe Data Practices: Educate users on the dangers of entering sensitive, confidential, or regulated data into AI tools.
- Threat Awareness: Train staff to recognize and report AI-related threats such as phishing, social engineering, or suspicious app behavior.
- Promote Approved Tools: Encourage the use of sanctioned AI solutions that comply with organizational security policies.
4. Restrict Access to High-Risk AI Applications
Use security tools to:
- Block Unauthorized Tools: Use in-browser blocking to restrict access to unauthorized AI platforms.
- Limit API Permissions: Implement least-privilege access for AI integrations.
- Enforce Secure Access: Require VPN or corporate authentication for AI tool access.
5. Vet AI Vendors for Security and Compliance
Before adopting an AI-powered solution, organizations should conduct due diligence:
- Vendor Screening: Review the AI provider’s data privacy policies.
- Regulatory Compliance: Ensure the application complies with industry regulations.
- Protective Contracting: Require contractual guarantees on data protection, retention, and security.
Conclusion
The adoption of GenAI in the workplace is inevitable, introducing significant security, compliance, and financial risks. Unmanaged shadow AI tools can expose organizations to data leaks, regulatory violations, and increased attack surfaces. However, organizations can take a proactive approach to managing shadow AI by implementing strong governance policies, enforcing access controls, and educating employees on responsible usage.
By balancing innovation with security, businesses can harness the benefits of AI without compromising data integrity or organizational resilience. Organizations that establish AI security best practices today will be better equipped to navigate an AI-driven future.
