Where All-In-One Security (AIOS) – Security and Firewall Wins
Lighter footprint
AIOS ships with a clean, modular interface that most small sites find easier to configure without drowning in toggles, and it does this while still scoring a 100/100 on compatibility.
Fresher release cadence
The plugin was updated on 2026-06-05, more recent than Wordfence's 2026-05-13 update, which can matter when patching newly disclosed WordPress vulnerabilities.
Where Wordfence Security – Firewall, Malware Scan, and Login Security Wins
Much larger install base
Wordfence reports 5,000,000 active installs versus AIOS's 1,000,000, a 5x lead that shows broader community trust and more third-party documentation.
Better support resolution
Wordfence resolves 86.3% of support threads compared to AIOS's 68.4%, a meaningful gap that matters when you need a quick answer during a live incident.
Stronger overall quality score
Wordfence lands at 97.05/100 on PluginCheck, nearly 6 points above AIOS's 91.23/100, reflecting its higher support score and larger user base.
Score-by-Score Comparison
Wordfence takes the full 100/30 versus AIOS's 90/30, driven by its 5 million active installs and broader recognition in the WordPress community.
Both plugins score a perfect 100/25, with AIOS updated slightly more recently (2026-06-05 vs 2026-05-13), so neither falls behind on release cadence.
Both tie at 94/15 with identical 94/100 user ratings, even though Wordfence's sample is much larger at 4,938 ratings versus 1,708, making Wordfence's score arguably more reliable.
Wordfence scores 86/15 versus AIOS's 68/15, an 18-point gap driven by an 86.3% resolution rate compared to 68.4%, which is the single biggest differentiator in this comparison.
Both plugins score a perfect 100/15 for compatibility, so there is no difference in how they play with modern WordPress and PHP versions.
The Bottom Line
Wordfence wins this comparison. It posts a higher PluginCheck quality score (97.05 vs 91.23), a 5x larger install base, and a substantially better support resolution rate (86.3% vs 68.4%), while matching AIOS on maintenance, ratings, and compatibility. For the most common use case, a standard WordPress site that needs firewall, malware scanning, and login protection with reliable backup, Wordfence is the safer pick. AIOS remains a solid free alternative if you prefer its lighter interface or simply do not need the extras.
