I was only using Jetpack for one feature, brute force login attacks.

However, now that there are more requirements, and given the fact that I’m managing 300+ websites, I decided to stop using it.

I wrote my own brute-force prevention code, see a tutorial here – https://getbutterfly.com/securing-your-wordpress-site-a-guide-to-limiting-login-attempts-without-a-plugin/

Hopefully, more plugins for Jetpack’s individual features will come out this year.
