LLM Penetration Testing for Your Business
LLM penetration testing attacks your AI application the way an adversary would. Omeiro tries direct and indirect prompt injection, jailbreaks, data extraction and abuse of the tools your agent can call, then reports what worked.

How our LLM penetration testing works
Scope the app
We note models, tools, data and what must stay private.
Attack it
Injection, jailbreak and extraction attempts are run.
Test the tools
Calls to your APIs and databases are probed for abuse.
Report and retest
Findings come with fixes, and Premium checks them again.
LLM penetration testing: scope, environment and what is attacked
The model is only one part of the target. LLM penetration testing also covers the system prompt, retrieval sources, tools the agent can call and the permissions behind them, because indirect prompt injection often arrives through a document or web page the model reads. Before ordering, describe what the app can do, what data it can reach and what outcome would worry you most, such as leaking another customer's records or taking an unapproved action.
A test environment keeps risk low. LLM penetration testing sends hostile prompts and may trigger real actions, so use staging data and low-privilege accounts where possible, with limits on spending. Share architecture notes, model providers and any guardrails you already use. Remember that results describe a moment in time, since prompts, models and tools change. Plan retesting after major changes, and treat each finding as a design question about permissions, not only a wording problem.
In short
- Delivery in 5 to 12 days, by package.
- Fixed price, shown before you order.
- Teams launching a customer chatbot connected to internal data.
- Developers giving an agent tool access and unsure about the risks.
- Copyright yours after full payment.
LLM Penetration Testing: common questions
How much does LLM penetration testing cost?
Prices are fixed and shown by package on our LLM Penetration Testing pricing page, so you see the full price before you order. You can also ask for a custom quote.
How long does AI application security testing take?
Delivery depends on the package: Basic 5-day delivery; Standard 8-day delivery; Premium 12-day delivery.
What is included in the Basic Package?
The Basic Package includes: 1 AI app: prompt injection & data leak checks, report. Higher packages add more scope, revisions and support.
Can I get a custom prompt injection testing package?
Yes. If none of the packages fits, use the custom package form on our pricing page to describe what you need, and our team sends you a fixed price.
Do you need production access?
A test environment is preferred. Agree this before starting.
Is RAG covered?
Premium covers RAG data access.
Do you re-test?
Premium includes a retest.
What is prompt injection?
It is an attack in which text given to a model, directly or hidden in a document or web page, tries to override its instructions. The danger grows when the model can call tools or reach private data.
What is the difference between AI red teaming and penetration testing?
Red teaming usually probes model behaviour and safety, such as harmful outputs, while penetration testing looks at the whole application, including tools, data access and APIs. Our tests cover both sides.
