Alerts that mean something — every time
AlertSite's intelligent alerting verifies every failure from multiple locations before notifying your team. Real problems get immediate attention. Transient blips get ignored.

Know about the problem before your users do
AlertSite sends alerts the moment a real failure is detected. With built-in retry logic and multi-location verification, false positives are filtered out automatically — keeping your on-call team focused on issues that matter.

Built to eliminate alert fatigue
Every component of AlertSite alerting is designed to give you signal, not noise.
Multi-Location Verification
When a monitor fails, AlertSite verifies the failure from a second location before sending any alert. If only one location sees the problem, it's retested — you're never paged for a network blip.
Contextual Alert Notifications
Every alert includes the monitor name, failure type, error message, response time, and a screenshot — everything your on-call team needs to start diagnosing before they've opened a browser.
Escalation & Routing
Route alerts to different teams based on monitor group, severity, or time of day. Configure multi-level escalation so critical failures always reach the right person.
Alert When It Matters
Set performance thresholds for response time, content validation, and SSL certificate expiry. AlertSite alerts you before a slow page becomes an outage.
AlertSite alerts integrate with your existing tools
Route alerts to PagerDuty, Slack, OpsGenie, VictorOps, AppDynamics, and more — with no custom integration work.
