Missing headers are invisible
You cannot see missing security headers by visiting a page. They require active inspection.
Security Headers
Security headers protect websites against clickjacking, MIME sniffing, and other attacks. MonitorMojo checks key security headers alongside uptime, SSL, and response time so you can see the full health picture.

Website health signals, not live monitoring data
The Problem
You cannot see missing security headers by visiting a page. They require active inspection.
CMS updates, plugin changes, and server config changes can remove security headers silently.
Most website owners do not check security headers. Agencies add value by including them in health reviews.
How It Works
Enter the website, subdomain, or client property you need to protect.
Run a real reachability, HTTPS/SSL, response time, and configured health check.
Use the returned signals to decide what to fix before a browser error or complaint.
Features
Check whether key security headers like HSTS, X-Frame-Options, and X-Content-Type-Options are present.
Check Content-Security-Policy, Referrer-Policy, Permissions-Policy, and other security headers.
Include security header findings in client health summaries alongside other monitoring signals.
Who This Is For
Add security header checks to your client onboarding and regular maintenance workflows.
Verify headers during development and after deployments to catch misconfigurations.
Quickly audit security headers across multiple client websites.
