PromptProtect 作者： Data Elicit Solutions

PromptProtect acts as a protective shield for businesses when using GenAI tools by serving as a first line of defense against accidental data leaks. The extension automatically detects and blocks or redacts sensitive information such as passwords, API keys, credit card numbers, IP addresses, and other PII, PCI, or PHI before it is sent to AI systems or external services. By catching careless pastes and sensitive data exposure in real time, PromptProtect enables employees to safely use AI tools while preventing confidential enterprise data from leaving the organization.

PromptProtect operates directly inside the browser and captures prompts before they are submitted to AI platforms such as ChatGPT, Gemini and other generative AI tools. The extension analyzes the text entered by the user, identifies sensitive information using multiple detection methods, and applies organizational policies to either block the submission or automatically redact sensitive data. This happens instantly and requires no manual configuration from employees other than signing in.

In addition to AI tools, PromptProtect also monitors text inputs on search engines to prevent employees from accidentally entering sensitive company information into public search queries or external websites. If sensitive information is detected in a search query or form submission, the extension can alert the user, redact the data, or block the submission according to the organization's security policies.

Administrators can centrally manage security rules using Role-Based Access Control (RBAC). Organizations can define custom policies that determine how different types of sensitive data should be handled for different employee roles. Policies can include blocking prompts, automatically redacting sensitive fields, or allowing specific data categories depending on the role and business need. PromptProtect also supports enterprise identity integration through SAML and LDAP, allowing organizations to deploy and enforce the extension across their workforce using existing identity providers.

The PromptProtect Admin Portal provides centralized visibility and governance over all AI and monitored web interactions within the organization. Administrators can view real-time telemetry including total prompts scanned, detected risk categories such as PII, PCI, PHI, secrets, and infrastructure data, and user activity across AI platforms. Detailed audit logs allow administrators to review original prompts, redacted prompts, and AI responses to investigate potential data exposure incidents.

For enterprise security operations, PromptProtect supports SIEM integration, enabling organizations to forward security events and logs to their existing monitoring systems for advanced threat detection, compliance reporting, and incident response.

By combining browser-level protection, automated sensitive data detection, enterprise policy enforcement, and centralized visibility, PromptProtect enables organizations to confidently adopt generative AI tools while maintaining strict control over sensitive data.

While PromptProtect uses advanced detection techniques to identify sensitive information, no automated system can guarantee perfect detection in every scenario. In some cases, certain sensitive values may not be detected or benign content may be flagged. The detection models and rules are continuously improved and updated over time to increase accuracy and reduce false positives, ensuring stronger protection as the system evolves.
