What's on this site?

The site has two primary sections, Resources and Blog. If you just want links, downloadable templates, tools etc. and don't need any explanations, Resources is your stop.

On the other hand, if, for example, you want to read about subdomain enumeration - what it is, why you care and how to do it well, for free, head over to the blog post on the topic first. The post explains all that, and links back to the Resources page for related "stuff" like an Excel template that will speed up the process.
