AI & LLM Penetration Testing for Prompt Injection, Data Leakage

Invadel provides expert AI and LLM penetration testing that uncovers vulnerabilities traditional security assessments miss. Our offensive security team targets LLM-powered applications and ML pipelines for the attack vectors that matter most: prompt injection, sensitive data and model leakage, insecure output and tool use, and RAG pipeline abuse.

Our testing methodology is aligned to the OWASP Top 10 for LLM Applications and covers direct and indirect prompt injection, system-prompt extraction, instruction and guardrail bypass, jailbreak techniques, training-data and PII leakage, context and memory bleed, excessive agency and tool abuse, unsafe downstream execution, retrieval poisoning, data-source injection, embedding and index abuse, and access control on sources.

Every engagement follows a structured process. We begin with a scope and kickoff phase where targets, roles, and rules of engagement are defined in writing with a fixed scope and timeline. Testing then goes live, and findings post to your live platform dashboard the moment our testers confirm them. Your team tracks remediation from open to fixed with severity, evidence, and status in one place. Executive and technical reports are delivered at the conclusion, followed by a complimentary retest.

We also test how well your guardrails, filters, and system prompts hold up against real bypass and extraction techniques, then provide hardening guidance for prompts, tooling, and pipeline configurations. Most engagements run approximately one to two weeks depending on the number of models, integrations, and tools involved.

Invadel helps security teams validate that their AI systems are resilient against adversarial attacks before real threat actors find the gaps.
