There are a few things you should always do first when investigating any website or server, whether it's for an Open-Source Intelligence investigation or just out of interest.

Consider the tech stack, server information, page list, SSL chain, domain registrar records, etc. Each of these can generally be found easily on its own using a combination of web resources and bash commands. It takes time to gather, compile, and analyze all of this data, though.

In order to automate this process, Web Check (or web-check) finds, organizes, and displays all the information required to give your inquiry a solid foundation. It generates a complete report without any filler in a matter of seconds.
