What SentinelWeb watches
One place to see everything that can break
From a single ping to a full user journey — SentinelWeb covers the surface area your reliability depends on.
Uptime monitoring
Scheduled checks run around the clock. Know about an outage before it reaches your customers.
SSL & domain expiry
Track certificate validity and domain registration, with warnings well before anything lapses.
Incident tracking
Every outage becomes a timeline — when it started, when it recovered, and the root-cause notes.
Public status pages
Publish a clean, hosted status page so customers always know where things stand.
Synthetic journeys
Script real user flows — sign-in, search, checkout — and catch breakage a simple ping never would.
Site health checks
Performance, security headers, SEO indexability, and malware scans across every monitored site.
How it works
From zero to monitored in three steps
- 01
Add what matters
Point SentinelWeb at a URL, or import a full multi-step user journey. Setup takes a minute.
- 02
SentinelWeb keeps watch
Your checks run on a schedule, around the clock — quietly recording every result.
- 03
You hear it first
The moment a check fails, an incident opens and you get alerted — with the context to act.
Incident tracking
From first alert to root cause, on one timeline
When a check fails, SentinelWeb opens an incident automatically and records everything that follows. No scrambling through logs to reconstruct what happened — the story is already written.
