Protect Your WordPress Site From Clickjacking Attacks by Adding the X-Frame-Options Header and Owasp's Legacy Browser Frame Breaking Script.
What It Does
WP Anti-Clickjack sets the X-Frame-Options HTTP header on your WordPress site to prevent other domains from embedding your pages in iframes. It also injects an older client-side frame-breaking script based on the legacy OWASP approach, which hides page content if the site is rendered inside a frame on older browsers. Together, these two layers aim to stop clickjacking attacks where users are tricked into clicking hidden elements.
Who It's For
This plugin suits administrators of small, compliance-sensitive sites that need a quick, single-purpose clickjacking fix without installing a full security suite. It is best for site owners who have already locked down other attack surfaces and just need to satisfy a specific PCI-DSS or internal audit requirement around frame embedding controls. Non-technical users who want a one-click X-Frame-Options toggle will also find it approachable.
Who Should Skip It
If you already use a major security plugin like Wordfence, Really Simple Security, or Jetpack, skip this: those tools already set X-Frame-Options (or the modern equivalent Content-Security-Policy frame-ancestors directive) out of the box. Anyone running a modern site on recent browsers should also consider a CSP-based solution instead, since the legacy OWASP JavaScript frame buster is a deprecated belt-and-suspenders approach.
The Bottom Line
WP Anti-Clickjack does one thing and does it well, with a recent update and a low minimum WordPress version that should not break anything. However, its tiny install base and essentially no community support mean you are trusting a single developer, and most users are better served by the clickjacking features already built into larger security plugins. Use it only if you specifically need a lightweight, standalone X-Frame-Options solution without the rest of a security suite.

Pick this if you need a firewall, malware scanning, and login protection alongside the same X-Frame-Options header.
Pick this if you already use Jetpack for backups or stats and want basic security headers without a separate plugin.
Pick this if you want free clickjacking protection plus a wider set of firewall, login, and database hardening features.
Pick this only if your main concern is SVG-related security; it does not address clickjacking and is not a direct alternative.
