Oh wow, this will be a game-changer! I run quite a few Plesk servers, and their continual cost increases plus their complexities in configuration make Enhance seem like a great option to consider. The few things I do rely on in Plesk that I wonder about are ModSecurity and fail2ban, and tweaking those to help secure sites and block bad bots.
I see that ModSecurity is available for nginx and Apache, but not OLS. I'm running nginx over Apache with Plesk, but for Enhance I've been running OLS. Thoughts on adding it for OLS? https://openlitespeed.org/kb/openlitespeed-modsecurity-module/
Any thoughts on fail2ban or CrowdSec for Enhance?
