01 / THE PROBLEMDATA CAN CARRY DIRECTIONS
An ordinary document.
An extraordinary
change of plans.
Your agent was asked to summarize a page. Somewhere in that page, someone asked it to do something else.
Prompt injection lives inside the content agents need to read. Trismag checks for known signs of instruction overrides, credential requests, hidden characters, and deceptive tool descriptions.

Follow the signal.
Across the context.
Open the playground ↗Catch the instruction
Some instructions arrive
in pieces.
Check messages together to surface patterns that emerge across the recent conversation window.
Know what a tool says
before you connect it.
Inspect descriptions and nested schema text for known manipulation. Tool capability and tool trust are different questions.
04 / TRUST, WITH RECEIPTSConfidence starts
Confidence starts
with clear limits.
A useful security tool should explain its findings—and be just as clear about what it misses.
Explore the trust center ↗Deterministic by design
Fixed rules, no LLM interpretation. The same input and engine version produce the same result.
Content is not a data product
The API processes scan text in memory. Our trust center explains request handling and the limits of that promise.
Known misses, in the open
Novel phrasing can pass. We distinguish regression tests from real-world accuracy and publish the limitations.
