Good plugin, wenig DE
Good plugin, easy to use but unfortunately insufficient German translation. Gutes Plugin, einfach zu bedienen, aber leider unzureichende deutsche Übersetzung. :-( schade

Essential First Install, Now Fully Localized in Arabic!
On every fresh WordPress installation, Security Optimizer by SiteGround is the first plugin I reach for.I deeply appreciate SiteGround's ongoing dedication to the WordPress ecosystem, most notably their enhancements to WP-CLI. As a token of gratitude for their excellent work, I am excited to contribute back to the community by finalizing the plugin’s localization into Arabic. This update will allow native Arabic speakers to manage their site security with greater ease in their own language.

Works Well on Hostinger VPS
As a long time user of StiteGround this is always loaded as standard.. Also very pleased to hear it works excellently on a Hostinger VPS I use for testing. Excellent plugin.

Works great
Easy to install and use. It provides more than login protection, it provides file protection, active logging, disabling file access, change the login url and so on. All whilst being a small non resource hogging solution. Much better and complete than all the small brute force login attempt plugins available that I have tested extensively.

Good Security Control
Installed it to improve my site security. The interface is simple, and most features work well. Had to tweak a few settings, but nothing complicated. Overall, pretty useful plugin. tnx devs.
