Spiderfoot is a centralised tool that takes key steps to fulfil a thorough OSINT engagement, especially in regards to asset discovery. Spiderfoot incorporates 100s of modules to extend its functionality, such as, enabling a module to scan for AWS S3 buckets; but rather than running a separate tool to find out. We can use Spiderfoot to enumerate the potential S3, and then display it within a formatted portal.

With web applications having such a big footprint, it's great to have a centralised managed asset discovery in one place. See below for Spiderfoot example:
