Uptime & SSL Monitoring
HTTP availability, response time and certificate expiry for every domain, from an independent location.
Each run fetches your site, follows redirects and inspects the certificate chain. You are alerted when the site is down for two consecutive checks, when it starts returning errors, when a certificate has 30, 14, 7, 3 or 1 days left, and when a chain stops validating.
Down/up alerts
Flap-protected: two failures before we page you, one success to resolve.
Certificate intelligence
Issuer, SANs, chain validity, legacy protocol support, key size.
Security headers
HSTS, CSP, X-Frame-Options and friends checked on every run.
Intervals down to 1 minute
On Enterprise; 5 minutes on Professional; 15 minutes on Starter.
