Prompt Injection Testing

The #1 LLM Risk, Found Before Attackers Do

Direct, indirect, jailbreak and multi-turn prompt injection testing for your AI products — mapped to OWASP LLM01.

Attack Classes We Test

Every category mapped to the OWASP LLM Top 10 and observed real-world incidents.

Malicious instructions sent directly by the end user to override system prompts and extract data or behavior.

Adversarial instructions hidden in retrieved documents, webpages, emails, or PDFs that the model reads.

Crafted prompts that bypass safety guardrails — role-play, multi-step setups, encoding tricks, language switching.

Attacks that reorder or contradict your system prompt to change tone, leak rules, or unlock disabled functions.

Conversation history poisoning that lands a payload across turns the model has not yet seen as malicious.

Prompts that coerce the model to encode private data into its response — URLs, markdown, or stylistic side-channels.

We inventory every input the model can see: user input, RAG chunks, tool outputs, system prompts, multimodal inputs.

We run a 200+ payload battery against your system, including custom payloads built for your domain and tools.

We stage tainted documents, sites, and tool responses to test whether your retrieval or browsing path is exploitable.

Every confirmed finding ships with a minimal repro, severity rating, and recommended fix.

Input filtering, instruction hierarchy, output validation, tool gating, content provenance — implemented with your team.

We re-test after remediation and issue a sign-off report suitable for security review.
