Your AI assistant can take actions now. Is anything watching what it does?

There's a version of this conversation that sounds like abstract threat modeling. This isn't that version.

If your product has a contact form, you're receiving spam, disposable-email signups and credential-stuffing attempts right now. If you've deployed an AI assistant, it's being probed for prompt injection and system-prompt extraction right now. If you've given it MCP tools — sending email, writing records, querying databases — the question of what it's allowed to do, and who's checking, is not theoretical.

Three problems, one common thread

The form problem

Bots don't look like bots anymore. Headless browsers, behavioral mimicry and distributed per-account credential stuffing pass a standard WAF check and a CAPTCHA.

The AI problem

A well-crafted prompt can extract your system instructions, redirect model behavior, or leak data from earlier in the context window. OWASP lists this as the number-one LLM risk.

The agent problem

When your AI can call tools — send, write, delete, schedule — a compromised context or injected instruction doesn't just extract information. It takes actions.

They all happen after authentication. The user or session has been verified. The threat enters in the interaction itself.

You don't need Shield to know who your users are. You need it to know whether what they're doing — or what your AI is doing on their behalf — should actually be permitted right now.

What changes with Shield in place

• Form abuse and credential stuffing are stopped before they reach your application logic — not cleaned up afterward.
• Your AI assistant has a protection layer in front of it that you control, without rebuilding the underlying system.
• Destructive agent actions require a gate. Nothing irreversible executes because an AI was told to by a manipulated prompt.
• Every decision is signed and stored — a complete record of what was allowed, what was blocked, and why.

Most teams discover they needed it after something goes wrong: a spam flood through the contact form, an assistant convinced to reveal its instructions, an agent that sent three hundred emails because a tool call wasn't gated.

Shield is preparing for launch. Pre-register for early access.
