What Really Simple Security does

Handles SSL redirection, security headers, hardening and two-factor login from one clearly written settings screen.

It sits in the security part of a WordPress stack and is sold by Really Simple Plugins on a freemium basis. We recommend it in our security guides because it does that one job well without asking you to rebuild the rest of the site around it.

Every plugin adds work to a page request, so treat this as a decision with a cost. Record a speed test before you install it and run the same test afterwards, on the same page, so you know exactly what it charged you.
