HTTP & HTTPS checks
Measures DNS, TLS handshake and time to first byte. Reads the status code and matches the body against a pattern.
ZeroDrop probes your endpoints from four locations. It pages you only when a configurable number of them agree that 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. Reads the status code and matches the body against a pattern.
Connects, times the 220 banner, upgrades with STARTTLS, and reads the certificate of the server.
Tracks the certificate issuer, chain and expiry as observed from each location.
Fires only when a configurable number of locations agree, and holds that verdict across several intervals. Quarantines a probe that disagrees with its 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.
