I like that we can test different scenarios of attacks without having risk for any data loss or compromise in real time environment with simulated traffic from users' devices using API calls made by third-party applications such as Facebook Messenger etc..
The tool is able not only simulate web browser but also mobile apps so it's very useful when testing new features implemented into existing platforms (eCommerce stores). Sometimes there are cases where simulator doesn't show all possible attack vectors which could be due bugs inside this product - sometimes they don’t respond fast enough if something goes wrong during tests execution e.,g.: slow network connection causing timeout errors while trying certain requests through an app interface; no response at some point leading us believe everything went fine although nothing was actually done properly because simulation didn´ t finish before timing out after several attempts were performed.; lackof proper notification about issues encountered along way towards solution resolution.- Easy integration between other components used within project development process.
