Site Monitoring

Run any combination of our 130+ diagnostic tools against your sites on a schedule. Track uptime, TLS health, DNS records, email authentication, response times, and security headers — from multiple locations, all in one place.

Every site, every check, at a glance

A single dashboard shows the live status of every site you monitor. Each monitor reports its current state, uptime over your chosen window, and the latest response time — so a problem is obvious the moment it appears.

  • Up / degraded / down status at a glance
  • Uptime percentage over 24h, 7d, or 30d
  • Latest response time per monitor
  • Checks run from multiple regions

Catch regressions, alert the right people

Every monitor runs on the schedule you choose — as often as once a minute. NetTests records each result, charts response time and availability over time, and notifies your team the instant a check crosses a threshold or fails.

  • Schedules from every minute to custom cron
  • Response-time & uptime history per monitor
  • Threshold alerts via Email, Slack, MS Teams & SMS
  • Time-to-first-alert in seconds, not minutes

Start monitoring your sites in 60 seconds

Add a site, pick your checks, set a schedule. NetTests handles the rest — running, storing, charting, and alerting around the clock.
