Biggest opportunity: Swap “anti spam” for “original”. “anti spam” isn't earning its slot: you're not in the first 24 results for its own search. “original” sits at #14 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active
At least 20K of 2.7M lifetime downloads are still running, below its category: the median Security plugin keeps 1.4%, across 1,061 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Security plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
