What does Astra do?
Astra is a security layer for AI agents that protects sensitive data during processing. It automatically tokenizes personal identifiable information (PII), protected health information (PHI), and payment card information (PCI) before data reaches AI models. The system replaces sensitive values with secure tokens that maintain the necessary factual information for reasoning without exposing the actual data.
The tool works by wrapping existing AI agents with a middleware that handles classification, tokenization, and execution automatically. Developers can integrate it with just three lines of code, and it supports multiple deployment models including cloud, hybrid, and fully air-gapped environments. Astra's ThinkingTokens allow AI models to reason about data patterns and relationships while keeping the actual sensitive information locked in a secure vault that only releases data for specific, authorized actions.
This solution benefits organizations working with sensitive data in healthcare, finance, and other regulated industries. It enables them to deploy AI agents for tasks like patient intake processing, financial transactions, and customer service interactions while maintaining strict data privacy and compliance standards. The system provides detailed audit trails for all token resolutions and actions, ensuring accountability without compromising security.
