Features include: * Admin settings page under Settings > Security Headers * HSTS controls with preload warning * Referrer-Policy and X-Frame-Options settings * Permissions-Policy custom value field * Content-Security-Policy builder with Report-Only mode * Diagnostics screen showing configured headers * Test tool to fetch and inspect your live response headers * Import, export, and reset settings tools * Cleanup on uninstall ### Why security headers important? When auditing websites, security headers are frequently forgotten. Although some may argue that website security is unrelated to SEO, it does become so when a site is compromised and search traffic completely disappears. Everyone who publishes content online should pay special attention to security headers. Getting hacked is not good. You lose traffic, customers and it’s a pain to resolve all the issues. But good thing you’re smart and have searched for this plugin :). ## インストール 1. Upload the plugin folder to `/wp-content/plugins/` 2. Activate the plugin in WordPress 3. Go to Settings > Security Headers 4. Save your preferred configuration ## FAQ ### Is Content-Security-Policy enabled by default? No. CSP is disabled by default because a strict policy can break scripts, styles, embeds, or third-party integrations if it is not configured carefully. ### Should I use Report-Only mode first? Yes. Report-Only mode is the safest way to start testing CSP because it reports problems without blocking resources. ### Does HSTS work on HTTP sites? No. HSTS should only be enabled when your site is fully available over HTTPS. ## 評価 ![](https://secure.gravatar.com/avatar/043fa4640ad96d725a6e59cff4538afca1f74558ac131a2c04fb537f032fec21? s=60&d=retro&r=g) ### 󠀁[Site Killer](https://wordpress.org/support/topic/site-killer-3/)󠁿 [nofarrell](https://profiles.wordpress.org/nofarrell/) 2023年5月29日 No warning, no instruction of what to do if you site goes down, no configuration options, deleting the plugin directory does not resort your website. From my experience, unless you have hours with nothing better to do except rebuild your WordPress website, installing advise not to install this plugin ![](https://secure.gravatar.com/avatar/b6398168f573fac25a612a2eea6c89261fd77ca69cf66857f4df344d91b37a8a? s=60&d=retro&r=g) ### 󠀁[great work – A+ score indeed!!!!](https://wordpress.org/support/topic/great-work-a-score-indeed/)󠁿 [vevsglobal](https://profiles.wordpress.org/vevsglobalph/) 2022年9月27日 I installed the plugin. great work!!!!!! from F score to A+ score.
