Stop leaking your company secrets to ChatGPT
PromptGuard analyzes your prompts in real-time and automatically masks sensitive data before it's ever sent to an LLM.
Trusted by companies where security matters
Your organization is leaking sensitive data - without knowing it
API keys, tokens, and passwords are often pasted into prompts without a second thought. Once sent, they're outside your systems - and outside your control.
Project names, client info, or legal notes get casually dropped into LLMs just to move faster or get help - without any filter.
Most companies have zero visibility into what their teams are actually sending to AI tools. They don't know what's leaked, when, or by whom.
