Wordfence Security Plugin: WordPress Speed Profile

Wordfence Security is a WordPress plugin used on 5M+ sites.
Some plugins — full security suites and firewalls especially — load before WordPress itself, run on every single request, and hook into WP-CLI and the bootstrap process. In our isolation sandbox that pushes routine WP-CLI operations past the 60-second limit, so a clean before/after measurement never completes — across repeated attempts. Rather than publish a misleading number we mark this plugin permanently un-benchmarkable. That is itself the finding: a plugin this deeply embedded will add real per-request overhead — but how much depends entirely on your configuration (firewall mode, live-traffic scanning, scan schedule), so no single comparable figure would be honest. Install it on staging and measure your own TTFB before trusting it on production.
Performance Analysis
Performance Impact
Wordfence Security – Firewall, Malware Scan, and Login Security could not be measured by our automated benchmark, and we mark it permanently un-benchmarkable. It is a full firewall and security suite that loads before WordPress on every request and hooks into WP-CLI itself, so an isolated before/after test never completes — across repeated attempts.
That limitation is itself the finding: a plugin this deeply embedded will add real per-request overhead, but how much depends entirely on your configuration — firewall mode, live-traffic scanning, and scan schedule. No single comparable number would be honest. See the Benchmark Status above, and test it on a staging site while measuring your own TTFB before trusting it on production.
