The filter at the door

Sting Observe.
Nothing harmful gets in.

Sting Observe checks every tool, skill, web page and file before your AI agent reads it. Harmful content is caught at the door, so your agent never learns a bad instruction.

The demo

Watch Sting Observe work.

Things arrive from outside. Observe reads each one: harmful ones are caught in the sieve, clean ones go straight to your agent.

Animation: things from outside float toward your company. Sting Observe, a filter gate, catches the harmful ones (hidden instructions, attempts to steer the agent, attempts to smuggle data out) and lets clean tools and skills reach your AI agent. The agent then sends work out through a back gate guarded by Sting Protect, which lets safe fixes and updates out, keeps the secret key home, and asks a human before deleting everything.

  1. 1

    Something arrives

    A tool, skill, web page or file your agent is about to use.

  2. 2

    Observe reads it first

    Before your agent sees a word, Observe checks it for hidden instructions and tricks.

  3. 3

    Caught or cleared

    Harmful content is stopped and recorded. Clean content reaches your agent right away.

The problem it solves

Your agent believes what it reads.

AI coding agents pull in outside content all day: MCP servers, plugins, packages, docs and web pages. Any of them can carry text written to give your agent orders.

The agent can't always tell your instructions from a stranger's. One hidden line can make it leak data, install something harmful, or quietly change course.

In plain words

If a stranger slips a note into your agent's reading pile, Observe reads it first and throws it out.
