Security headers on 4,688 small-business websites: 49.7% met none of 7 criteria

So.. you've written up what you checked, and what didn't match what ever criteria you had.

But.. what does it mean? Why enforce certain headers? Why enforce certain options? There is a section which kinda looks at this, but not really.

You have a bunch of links at the end for resources, but why not just provide the rationale for each rule or option inclusion in the article as well? What does each prevent or allow and why?

It’s ridiculous that the answer to a secure web is for everyone to sprinkle the magic salt and not something on the browser side

And if any of the websites use .NET, they can get almost all of the recommended security headers in one line by using a NuGet package I created: https://gaprogman.github.io/OwaspHeaders.Core/

for static sites on a VPS it's fair to expect the host to provision these, yes?

Nice work! You gave me something to fix!!
