The model sees only what’s allowed

Kordon checks every request before it is sent. It swaps personal data and keys for placeholders, blocks hidden instructions and keeps confidential documents on a local model

  • Local laws and languages. Masking and policies adapt to each market. In the US: CCPA and HIPAA, English and Spanish, SSN, ITIN and driver’s license formats.
  • Encodings. Base64, hex and URL encoding are decoded before the check — a key in a config won’t slip through.
  • Reversible. Placeholders last for the conversation: the employee gets the answer back with their own data.

Hidden instructions never reach the model

An instruction can hide in an email, on a web page or inside a “game”. Kordon finds it before the request goes to the model
