I completely agree. However, some tools have a large toolbox built-in and reduce the need for other tools. Eg: dnsdist allows you to do general ratelimiting/blocking, but allows you to build your own rules as well.

Note that I can buy a great, expensive and high-quality garage toolbox, but that that doesn't mean I can repair my own car. The toolbox is what the knowledgeable expert needs to fix the problem...

Kind Regards and best of luck fending of the bad people...
