The Harness Is the Hard Part of Agentic Pentesting

An AppSec team can easily set up an AI agent to run attacks on their own web apps with minimal configuration. The AI model generates the attacks, but the surrounding harness is what ensures the attacks are safe to run against production systems and provides valuable insights afterwards. The harness is where the majority of the engineering effort in AI pentesting lies, making it a crucial component. A recent example of the importance of the harness is the Hugging Face intrusion disclosed by OpenAI in July. The harness plays a key role in making AI pentesting effective and reliable. The complexity of the harness is a significant challenge in AI pentesting.
