Decision brief

FuzzyAI is an automated tool from cyberark for detecting and mitigating jailbreaks in LLM APIs using fuzzing techniques.

Good fit when

  • When you need to identify vulnerabilities specifically within the API layer of your large language models (LLMs).
  • If your security strategy includes a proactive approach to catching potential exploits through automated testing.

Avoid when

  • For general application or code-level vulnerability scanning, as it is specialized for LLM APIs.
  • In scenarios where manual penetration testing of applications outside the scope of LLMs is required.
