AI Security & LLM Penetration Testing

As you ship AI features, chatbots and agents, you expose a brand-new attack surface. Attack Insights penetration tests your AI applications against the OWASP Top 10 for LLMs — and proves what an attacker could actually do.

Definition

Securing the AI you build and deploy

LLM-powered apps — assistants, copilots, RAG pipelines and autonomous agents — introduce risks that traditional application security was never designed to catch: prompt injection, data leakage through model responses, over-privileged agents, leaked system prompts and poisoned data or models. The OWASP Top 10 for LLM Applications is the industry reference for these risks. Attack Insights tests your AI systems against that framework using adversarial techniques, then validates each finding so you act on real, demonstrated exposure — not theory.

We test, not just advise. Aligned to the OWASP Top 10 for LLM Applications, our AI penetration testing actively attempts prompt injection, data exfiltration and agent abuse, and only reports findings we can prove.

Why it matters

AI adoption is outrunning AI security

Teams are racing to embed LLMs into customer-facing and internal products, often without security review. A single prompt-injection or excessive-agency flaw can leak data, trigger unintended actions or expose your system prompt and connected tools. Testing AI features the way an attacker would is now essential before and after you ship.

OWASP Top 10 for LLMs

What we test for

Prompt injection

Direct and indirect attempts to override instructions and hijack model behaviour.

Sensitive information disclosure

Coaxing the model into leaking data, secrets or other users’ information.

Improper output handling

Unsafe handling of model output that leads to XSS, SSRF or code execution.

Excessive agency

Over-privileged agents and tools that can take unintended, harmful actions.

System prompt leakage

Extraction of hidden system prompts, guardrails and connected credentials.

Supply chain & poisoning

Risks in models, plugins, training data and third-party AI components.

Vector & embedding weaknesses

Attacks on RAG retrieval, embeddings and knowledge-base poisoning.

Unbounded consumption

Resource-exhaustion and cost-amplification abuse of model endpoints.

How it works

How AI penetration testing works

01

Discover AI assets

Map your LLM features, endpoints, agents, tools and data flows — in white-, grey- or black-box mode.

02

Adversarial testing

Run targeted attacks for each OWASP LLM risk, probing how the system behaves under abuse.

03

Validate

Confirm every finding by demonstrating real impact — unproven issues are discarded, not reported.

04

Report & retest

Deliver evidence, reproduction steps and remediation guidance, then retest fixes.

FAQ

AI Security FAQ

What is the OWASP Top 10 for LLMs?

It is the industry-standard list of the most critical security risks in LLM applications — including prompt injection, sensitive information disclosure, excessive agency and system prompt leakage — used to guide AI security testing.

What is LLM penetration testing?

It is adversarial testing of AI and LLM-powered applications: actively attempting prompt injection, data exfiltration, agent abuse and related attacks to find and validate real, exploitable weaknesses.

Do you test for prompt injection?

Yes. Direct and indirect prompt injection is a primary focus, alongside the other OWASP LLM Top 10 risks.

Is it safe to run against production AI?

Yes. Testing is controlled, with guardrails and scope enforcement, and is designed to be safe against live systems.

How is this different from normal application pen testing?

It targets risks unique to LLMs — model behaviour, prompts, agents, embeddings and AI supply chain — that traditional application testing does not cover.
