Burp's current Scanner maintains a queue of items that have been sent for auditing, and processes them in turn. Each item is processed in isolation, and its status moves from waiting, to in-progress, to done.

Burp's new Scanner uses a different model. There is still a collection of items that are to be audited. But Burp divides the work into multiple phases. 

The audit phases are divided into three areas:

• Passive phases
• Active phases
• JavaScript analysis phases

Within each area, there are multiple distinct phases: for example, there are five different phases of active work. Within each area, each phase is performed for all items, before moving on to the next phase.

Below is what the new UI for monitoring the progress of an audit scan looks like. This is now shown for all kinds of scan, even those that only employ passive detection techniques.

The new UI lets you clearly track the progress of individual items, as each phase transitions from not started, to in progress, to complete. Over the next few days, we'll be describing various exciting new capabilities that are made possible by the new multi-phase scanning model.
