- The preview displays a 16-test assessment: 11 resisted, 5 exploited, and 5 critical findings; its results are simulated.
Field notes
The assessment flow follows an adversarial test through agent execution, tool calls, transaction state, and a security finding. The preview lists six test areas, including payment integrity and business logic, and displays a 16-test example with simulated results. For a team’s own agent, the page asks visitors to request an assessment and share its capabilities and workflow.
