Security Alerts

Security alerts keep you informed about SSL issues, missing security headers, mixed content, and domain health problems. SiteMonitor scans your domains daily and alerts you when action is needed.

How it works

01

Add your domain

Add your domain and SiteMonitor starts scanning for SSL issues, vulnerabilities, and security misconfigurations.

02

Continuous scanning

We run daily security scans covering SSL certificates, headers, mixed content, and known vulnerabilities.

03

Instant security alerts

When we detect an issue like an expired SSL certificate, missing security headers, or a new vulnerability, you get an alert.

What are website security alerts?

Website security alerts notify you when your site has security misconfigurations or vulnerabilities that could put your users at risk. This includes expired or misconfigured SSL certificates, missing security headers, mixed HTTP/HTTPS content, and appearances on domain blacklists.

An expired SSL certificate can block users from accessing your site entirely. Missing security headers leave your site vulnerable to common attacks like clickjacking and cross-site scripting. SiteMonitor catches these issues early so you can fix them before they cause damage.

What we scan for

  • SSL certificate expiry monitoring with advance warnings
  • SSL chain and configuration validation
  • Security header analysis (HSTS, CSP, X-Frame-Options)
  • Mixed content detection
  • Domain expiry monitoring
  • Blacklist monitoring across major databases
  • TLS version and cipher suite checks
  • Automated daily security scans

Frequently asked questions

SiteMonitor scans for SSL certificate problems (expiry, misconfiguration, weak ciphers), missing security headers (HSTS, CSP, X-Frame-Options, X-Content-Type-Options), mixed content issues, domain expiry, and blacklist appearances. We run these checks daily.
SiteMonitor sends SSL expiry warnings at 30, 14, 7, 3, and 1 day before expiration. This gives you plenty of time to renew your certificate, even if auto-renewal fails.
SiteMonitor focuses on infrastructure-level security: SSL/TLS configuration, security headers, and domain health. For application-level vulnerability scanning (SQL injection, XSS), we recommend dedicated security tools. SiteMonitor complements these tools by monitoring the security basics continuously.
Security headers are HTTP response headers that instruct browsers to enable security features. For example, HSTS forces HTTPS connections, CSP prevents cross-site scripting, and X-Frame-Options blocks clickjacking. Missing headers leave your site more vulnerable to common attacks.
Yes. You can monitor as many domains as your plan allows. Each domain gets its own security dashboard showing the current status of all security checks, along with historical data and recommendations for improvement.
