The Compliance Gap

Your secrets are leaving the browser.

Employees are pasting sensitive code and customer PII into ChatGPT every day. You shouldn't have to choose between productivity and privacy.

Employees paste sensitive data into public models.
API keys and credentials are accidentally sent to LLMs.
Security teams have no logs of what data is leaving the VPC.
IT blocks ChatGPT entirely.
