Prompt Injection Resistance Audit
Independent, evidence-based verification that your AI agent resists hidden instructions buried in the content it reads — emails, tickets, documents, web pages, and tool output. From $249, delivered in 2–3 business days.

Why this matters right now
Every new frontier model release widens what agents are allowed to do — browse, read inboxes, call tools, move money. Prompt injection has been the #1 entry on the OWASP Top 10 for LLM Applications since the list existed, and it remains unsolved at the model layer. As agents gain autonomy, the blast radius of a single hidden instruction grows with them. Buyers have noticed: injection resistance is now a standard question in enterprise security review, and "we handle that" is no longer an accepted answer.
What is a prompt injection attack?
An attacker hides instructions inside content your agent reads, and the agent follows them instead of yours. There is no exploit code and no malware — just text that looks like a command to a system that can't tell commands from data.
Direct injection
A user types the manipulation straight into the conversation to override your system prompt or unlock restricted behavior.
Indirect injection
The payload sits in third-party content your agent retrieves — a web page, PDF, ticket, or calendar invite. No human ever sees it.
Silent tool hijack
The visible answer looks clean while an unauthorized tool call already fired. Only tool-call logs reveal it.
If you're shipping a new agent
- Clear enterprise security review with a third-party report instead of a questionnaire.
- Find exfiltration paths in week two, not after your first breach.
- Stand out in a category where everyone claims to be safe and nobody can prove it.
- Hand investors a real technical diligence artifact.
If you're an enterprise deploying agents
- You carry the liability — vendor assurances aren't a defense.
- One consistent bar applied across every agent you evaluate.
- Documentation that maps to OWASP LLM Top 10 and NIST AI RMF review.
- A dated baseline to re-test against as models and tools drift.
What the report looks like
Every certified agent receives a publicly verifiable certificate ID. Anyone can confirm it at agentvet.ai/verify.
We grade your agent's output artifacts only — the same evidence standard used across every AgentVet Lab benchmark.
You additionally provide a tool-call log, so we can catch silent hijacks that leave no visible trace in your agent's output — stronger assurance for high-stakes deployments.
