HTTP & HTTPS checks
Measures DNS, TLS handshake and time to first byte, checks the status code, and matches the body against a pattern.
ZeroDrop probes your endpoints from four locations and pages you only when a configurable number of them agree something is down.
Probing from four locations
Protocol-aware checks, consensus that ignores blips, and alerts that reach you.
Measures DNS, TLS handshake and time to first byte, checks the status code, and matches the body against a pattern.
Connects, times the 220 banner, performs the STARTTLS upgrade, and reads the presented certificate.
Tracks the certificate issuer, chain and expiry as observed from each location.
Fires only when a configurable number of locations agree, with hysteresis and automatic quarantine of probes that disagree with their peers.
Webhook and email notifications, incidents opened and closed automatically, and maintenance windows to mute planned work.
Manage checks over a REST API, or declare them as code and apply them with one idempotent request.
