Prompt Injection Testing

Testing whether attackers can hijack your AI with crafted input, the number-one risk in the OWASP LLM Top 10.

What is Prompt Injection Testing?

Prompt injection testing checks whether an attacker can override your AI's instructions through crafted input, making it ignore its rules, reveal hidden prompts and data, or perform actions it should not.

Why it matters

Prompt injection is the LLM equivalent of injection attacks, and the top entry in the OWASP LLM Top 10. Because user input and system instructions share the same channel, a successful injection can fully subvert your AI's behaviour.

How Solusec tests it

We test your application with a wide range of direct injection techniques, then verify what each one actually achieves against your guardrails, data and tools, and recommend concrete mitigations.

AI testing, led by a human

Solusec is one of the first firms worldwide accredited under CREST's AI-Enabled Penetration Testing standard, so our use of AI is independently assured: responsible, transparent and always human-led. You get faster, broader testing, your data stays out of public AI tools, and every finding is validated by a qualified tester. Read about the accreditation.

What you get

You get a clear, prioritised report mapped to business risk, a walkthrough of every finding with practical fixes your developers can action, and a free retest once you have remediated. No scanner dump, no jargon, no sales team: you deal directly with the tester.

Common questions

What is prompt injection?

An attack where crafted input manipulates an LLM into ignoring its intended instructions, the top OWASP LLM risk.

Can prompt injection be fully prevented?

It cannot be eliminated entirely, but its impact can be greatly reduced with the right controls, which we test and recommend.

How quickly can testing start?

After a short, free scoping call we give a fixed price and a start date, often within days.

Is your AI use safe and independently assured?

Yes. Solusec holds CREST's AI-Enabled Penetration Testing accreditation, which independently assures that our AI use is responsible, secure and human-led.
