Nothing on this page is picked by hand. Every day we walk the whole WordPress.org directory, then score every plugin against Defender Security on three signals: sharing a category top 10 counts most, then appearing in the same WordPress.org rankings, then carrying the same tags, with rare tags counting for more than common ones like "wordpress". Plugins by the same author are excluded, so an author's own add-ons cannot fill the list, and so is anything rated below 4.0 or with fewer than 100 active installs. The ten highest scores are what you see, in that order. Full methodology.

Security Plugin, Firewall & Malware Scanner with Auto Removal is the closest match to Defender Security by the data we track, and Wordfence Security has the widest reach with 5 million+ active installs. Limit Login Attempts Security shipped the most recent release, on September 1, 2026. The list is rebuilt every day from WordPress.org, so a plugin that stops being maintained drops out on its own.
