Prompt Injection Defense
Catch malicious prompts before your AI ever acts on them.
Prompt injection is not theoretical. Attackers hide instructions inside the things your AI is supposed to read. An email your AI summarizes. A document your AI processes. A support ticket your AI responds to. A web page your AI scrapes. The instructions look like normal content to a human. To your AI, they are commands.
Your AI reads them. Your AI follows them. Suddenly an autonomous agent is sending customer data to an outside email address, deleting records it was never asked to delete, or posting messages it was never authorized to send.
The risk is not the attacker. The risk is that your AI cannot tell the difference between data it is supposed to read and instructions it is supposed to follow. To the model, everything that comes in is just text. The hidden instruction reads the same as a normal sentence.
This is the structural gap. Your AI was built to be helpful. Helpfulness without a control layer is a vulnerability. Helpful followed the instruction. Nothing checked whether the instruction was allowed.
Mountain Theory sits between your AI’s reasoning and the action it is about to take. We evaluate every input going into your AI and every output coming back out in under 200ms. Clean prompts pass through. Malicious ones get blocked or held for human review. Every attempt is logged.
Built for environments where one compromised prompt can trigger real-world consequences. Public safety. Defense. Financial services. Healthcare. The places where an autonomous action carries an immediate cost.
You want your AI reading customer emails, processing documents, and handling tickets. You also do not want a buried instruction in one of them turning your AI into the attacker’s tool. Mountain Theory lets you do both.
- ✓Real-time detection of malicious instructions hidden inside content your AI reads
- ✓Checks on both what goes into the AI and what comes out before any action executes
- ✓Policy written in plain English, not code
- ✓Three outcomes at every gate: allow, hold for human review, or block
- ✓Coverage for prompts hidden in emails, documents, web pages, support tickets, and any other content source
- ✓Full audit trail of every blocked attempt, ready for any incident response
- ✓Decisions made in under 200ms so the business keeps moving
Bottom line: malicious instructions stop at the line, every attempt is logged, every policy is written in plain English, every incident response is defensible without a translator.
