Sinaptic

Sinaptic is an essential data protection extension designed to prevent the unintentional exposure of sensitive data, including Personally Identifiable Information (PII) and Protected Health Information (PHI), when interacting with various AI services such as ChatGPT, Claude, and Gemini. By operating directly within your browser, Sinaptic ensures that confidential information remains secure, providing a critical layer of defense against data leakage in the evolving landscape of AI-powered workflows. It emphasizes privacy, local processing, and robust security measures tailored for both individual users and enterprise environments.

How to use Sinaptic

Users install the Sinaptic browser extension (available for Chrome, Edge, and Safari). Once installed, it operates in the background, automatically scanning user input in real-time within browser text areas. When sensitive data like credit card numbers, emails, or API keys are detected, Sinaptic provides immediate visual feedback (wavy underlines and tooltips) and blocks the transmission of this data before it leaves the browser. Users can configure custom exclusion rules for specific URLs or values, or choose to monitor all domains or whitelist specific ones, providing flexible control over data protection.

Core Features of Sinaptic

• Real-time Detection: Instantly scans user input using a hybrid engine of Regex and NLP to detect PII/PHI like credit cards, emails, and API keys before transmission.
• Smart Validation: Reduces false positives with advanced logic, including the Luhn algorithm for credit cards and context awareness to differentiate real sensitive data.
• Network Interception: Injects into the page context to intercept network requests, blocking sensitive data transmission at the source, giving you full control.
• Visual Feedback: Highlights detected sensitive data directly in text areas with non-intrusive wavy underlines and tooltips, educating users in real-time.
• Custom Rules: Allows configuration of exclusion rules for specific URLs or values, offering "Monitor All" mode or whitelisting specific domains for flexible control.
• Privacy First: All data processing occurs locally on the device; no user data is sent to Sinaptic's servers, and logs are stored locally and hashed for security.
• Enterprise-Grade Security: Built on Manifest V3 architecture with local processing only, audit & logging capabilities, and privacy-preserving device identification.
• NIST AI RMF Alignment: Directly maps to the Govern, Map, Measure, and Manage functions of the NIST AI Risk Management Framework, transforming policies into practical controls.

Use Cases for Sinaptic

Sinaptic is ideal for individuals and organizations looking to secure their interactions with AI tools. It's perfect for freelancers and employees needing to prevent accidental sharing of client data or personal information. For enterprises, CISOs, DPOs, and compliance teams can leverage Sinaptic to enforce data governance policies, meet regulatory requirements (e.g., GDPR, HIPAA, ISO), and quantify AI-related data leakage risks. Developers can use it to prevent inadvertently pasting API keys or proprietary code into public AI models, safeguarding intellectual property. Healthcare and finance professionals can ensure adherence to strict privacy standards when using AI for analysis or content generation involving PHI and PII.

Advantages of Sinaptic

Sinaptic offers proactive data leak prevention by blocking sensitive data *before* it leaves the browser, providing a robust first line of defense. Its privacy-centric design ensures all data processing happens locally on the user's device, guaranteeing zero data exfiltration. The tool boasts high accuracy and low false positives through advanced validation techniques like Regex, NLP, and the Luhn algorithm. It provides real-time visual feedback, educating users on data security best practices. For organizations, it's enterprise-ready with features like centralized policy management, SIEM integration, and SSO, and is built by compliance experts, aligning with major regulatory frameworks such as NIST AI RMF, GDPR, and HIPAA.
