Why Monitor SSL Certificates?

SSL certificates are essential for website security and trust. An expired or invalid certificate can cause:

  • Website Outages – Browsers block access to sites with expired certificates
  • Lost Revenue – Users can't complete purchases or sign up
  • SEO Penalties – Search engines demote sites with security issues
  • Damaged Trust – Users lose confidence in your brand

With CertWatch, you get automatic alerts before your certificates expire – giving you time to renew without any downtime.
