More than up or down
Uptime tells you the site answered. The same monitor also records what it answered with: the software it discloses, the headers it sends, the certificate it presents. When any of that changes you hear about it, and the change is kept.
The server, framework and CMS versions your site discloses, matched against end-of-life dates and known CVEs, with actively exploited ones escalated. New, resolved and escalated findings go out on the same channels as outages: email, Slack, JIRA, Linear, Teams.
A timeline per domain with incidents and security changes side by side: a header dropped, a certificate swapped, a grade that moved, an outage. Kept 12 months on Free, 2 years on Pro, forever on Enterprise. Evidence, not just a dashboard.
Every check mapped to SOC 2, ISO 27001, NIST CSF, NIST 800-53, PCI DSS and HITRUST, with evidence export for your auditor.
When downtime hits, visitors stay on your URL and see a branded offline page instead of an error. When you recover, they're redirected automatically. No third-party status page to maintain. No manual updates. No forgotten "we're back!" posts.
