Codeastra — Agent Data Blindness

Codeastra protects sensitive data , patient SSNs, medical record numbers, financial information, personal identifiers before it ever leaves your browser. How it works: When you compose an email in Gmail containing sensitive data and click Send, Codeastra intercepts it, replaces every sensitive value with a secure vault token, and then sends the email. The real values never reach Gmail's servers. When a colleague from the same workspace opens the email, all tokens are automatically resolved back to real values inline. No copy-paste. No manual steps. What it protects: SSN, MRN, credit card numbers, email addresses, phone numbers, dates of birth, employee IDs, case references, financial amounts, and more. Who it is for: Healthcare teams sharing patient referrals. Legal teams sharing case details. HR teams sharing payroll data. Any team that sends sensitive information over email. Security model: Real values never travel in email. Only tokens do. Tokens are stored in your encrypted Codeastra vault. Only users from the same workspace with a valid API key can resolve them. Expired tokens and wrong-workspace keys are always blocked. Requirements: A free Codeastra API key from app.codeastra.dev
