Protect Sensitive DataWherever It Flows
Whether you're building AI applications, modern APIs, customer platforms, or enterprise software, Securelytix protects sensitive information before it reaches external systems using tokenization, secure data vaults, dynamic masking, and controlled data restoration.
The Hidden Problem
Your data doesn't leak.It disperses.
Every prompt copies sensitive data into logs, vector stores, and model memory you'll never audit. Once it's out, you can't call it back.

- Vendor model retention windowsUP TO 30D
- Prompt-injection exfiltrationUNBOUNDED

The Vaultkey Protocol
Sensitive data checks in.Only tokens check out.
A five-stage protocol converts raw enterprise data into structurally identical tokens before it ever touches a model provider.
