It's the main knob you have to balance thoroughness, scan time, and cost. The rule of thumb is to pick the mode that matches the size of your app, not the size of the problem you're worried about. The scan mode selection step showing Quick, Standard, and Deep options with their descriptions ## The three modes Optimized for small-scale applications with limited scope. Ideal when the surface area is small and doesn't require extensive coverage. Good fits include a small marketing site, a single API with a handful of endpoints, or a smoke test to verify your setup is wired up correctly. Suited for applications with moderate scope. Provides broader coverage across typical features and workflows. This is the right default for most production apps. It exercises authentication flows, common vulnerability classes, and multi-step interactions, without the time investment that Deep requires. Designed for large-scale applications with complex workflows and extensive scope. Best for thoroughly analyzing multi-step interactions and intricate application logic. Deep chains findings across endpoints, spends more runs on the parts of the app that take a while to tease apart, and tries harder exploitation techniques.
