Hey there PenTwist, I’m very sorry to hear that Protect isn’t functioning as you are expecting. May I ask if you are using the free or upgraded version of the plugin?
Currently, the free version of Jetpack Protect provides reporting on known vulnerabilities found in the themes and plugins currently installed on your site, brute force login attack protection, and a manual IP block and allow list.
The upgraded version of Protect includes a Web Application Firewall (WAF) that inspects every request against our advanced security rules and blocks bad actors, as well as advanced line-by-line malware scanning for your site. Protect does not include rate limiting or DDOS attack protection at this time.
Please let us know if you have any other questions or feedback about the plugin!
