LLM application security testing

Before customers or attackers find the weak spots in your AI features, we do. Testing covers the AI-specific risks and the conventional ones around them.

Fortify Experts tests chatbots, copilots, retrieval-augmented generation (RAG) systems and AI agents against the OWASP Top 10 for LLM Applications, with findings ranked by impact and clear remediation guidance.

Common findings we test for

  • Prompt injection that overrides your instructions
  • Sensitive data revealed through responses or retrieved documents
  • Agents and tools taking actions beyond their intended permissions
  • Unsafe handling of model output in downstream systems
  • Weak access control between users and tenants in AI features

Questions we hear

What do you test in an LLM application?

Prompt injection, direct and indirect; sensitive data disclosure; insecure handling of model output; excessive agency in agents and tools; supply chain and plugin risks; and the conventional web and API security around the AI feature.

Do you need access to our model?

Not necessarily. Most testing runs against the application the way a user or attacker would. Access to prompts, configuration and architecture lets us test more deeply.
