The solution
A smart supervisor, not just a ping.
Perimon confirms incidents before alerting — preventing the false positives that cause alert fatigue. Every status has a precise meaning.

Site is responding but slowly (configurable threshold).
Site is unreachable. Incident confirmed, alert sent.
Planned maintenance. Monitoring paused.

The right frequency for your needs.

For active SaaS products and e-commerce sites.

For mission-critical, high-availability services.

From first signal to resolution — every step tracked.
Perimon doesn't fire on the first sign of trouble. It confirms, escalates, then resolves. Full history is retained.
Unusual behavior detected.
