Delaying a signature is common for any large company. The contract between Tom Hunter and an online pet store for thorough penetration testing was no exception. It was necessary to check both the website and the internal network, as well as the working Wi-Fi. It's no surprise that the urge to scan the site arose even before all formalities were settled.
