Security measures for my website.

Hi, I’m interested in making my site more secure to prevent any malicious intent of hacking my page. I’ve found that I should implement this in order to make my site more secure: Strict-Transport-Security , Content-Security-Policy , X-Frame-Options , X-Content-Type-Options , Referrer-Policy , Feature-Policy .
My site has subdomains and a Wix Blog, if that’s relevant.

Thanks in advance.

Otherwise, you can look into Wix Fetch and Wix HTTP Functions for more info.
