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 :).
Installation
- Upload the plugin folder to
/wp-content/plugins/ - Activate the plugin in WordPress
- Go to Settings > Security Headers
- 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.
