Features
Everything you need to stay ahead of downtime
SentinelWeb brings uptime, user journeys, incidents, and site health into one focused monitoring workflow.
Monitoring
Watch what keeps your business online
The core checks that tell you, immediately, when something is wrong.
Uptime monitoring
Scheduled checks run around the clock from the moment you add a site. Catch downtime the instant it starts.
SSL & domain expiry
Track certificate validity and domain registration dates, with early warnings well before anything lapses.
Synthetic journeys
Script multi-step user flows — sign-in, search, checkout — and verify the paths that actually matter.
Health & visibility
Context when it breaks, confidence when it doesn't
Beyond up-or-down: the signals that keep your site fast, secure, and discoverable.
Public status pages
Publish a hosted status page so customers can see current and historical status without emailing support.
Incident alerts
When a check fails, an incident opens and SentinelWeb notifies you by email so the right people can respond.
Performance checks
Measure page speed and core performance signals so slowdowns surface before users complain.
Security headers
Inspect security headers and TLS configuration to catch misconfigurations that weaken your site.
Malware & Safe Browsing
Scan monitored sites against malware and Safe Browsing signals to catch compromises early.
SEO & indexability
Check robots rules, sitemaps, and indexability so search engines can always reach your pages.
How it works
What happens from the first check to the status page
Every capability on this page works together in one flow — here is the whole loop.
- 01
Add a site or journey
Point SentinelWeb at a URL, or import a multi-step user journey. Setup takes about a minute.
- 02
Checks run on schedule
Your checks run around the clock, quietly recording every result as it comes in.
- 03
A check fails
The moment a check returns an error or misses its target, SentinelWeb registers the failure.
- 04
An incident opens
SentinelWeb opens an incident automatically and emails you, so the right people can respond.
- 05
Your status page updates
Your hosted status page reflects the change, so customers see it without contacting support.
Uptime monitoring
Know the moment a site stops responding
From the second you add a site, SentinelWeb checks it on a schedule and keeps watching — so downtime is something you are told about, not something you discover.
- Scheduled checks run around the clock — no manual triggering
- Every check verifies the response status and records the result
- Recovery is confirmed automatically once checks pass again
Synthetic journeys
Test the flows your customers actually use
A homepage that loads is not the same as a checkout that works. Synthetic journeys replay real multi-step flows so you catch breakage where it costs you.
- Script real, multi-step flows: sign-in, search, add to cart, checkout
- Authenticated pages behind a login are covered, not just public URLs
- A break in any single step is caught — not just a failed homepage ping
- 01Open homepage320 ms
- 02Sign in540 ms
- 03Search catalog410 ms
- 04Add to cart380 ms
- 05Complete checkout720 ms
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.
- Automatic incident creation the moment a check fails
- A precise timeline of degradation and recovery
- Root-cause notes kept with the incident, not in chat
- 14:02Incident opened
Checkout flow returned HTTP 503
- 14:03Investigating
Response time climbing across two regions
- 14:09Recovered
Checks passing again — monitoring
- 14:21Resolved
Root cause: upstream payment timeout
Site health checks
Catch the problems that never trip an alarm
Some failures are quiet — a slow page, a missing security header, a page search engines cannot reach. Health checks surface them before they cost you.
- Performance and core speed signals on every monitored site
- Security headers and TLS configuration checked for misconfigurations
- Malware, Safe Browsing, and SEO indexability checks alongside uptime
Who it's for
Built for the teams whose business runs on the web
The same checks, framed around what each team stands to lose when a site goes quiet.
SaaS teams
Watch sign-in, dashboards, and API endpoints. Catch breakage introduced by a release before a customer reports it.
Agencies
Monitor every client site from one place, and give each client a hosted status page of their own.
E-commerce
Keep the paths that earn revenue — search, cart, checkout — under synthetic journeys, with SSL and domain expiry tracked alongside.
FAQ
Features, in detail
What can SentinelWeb monitor?
Website uptime, SSL certificates and domain expiry, and full multi-step user journeys — plus performance, security, and SEO health checks on every site you add.
What is the difference between uptime monitoring and synthetic journeys?
Uptime monitoring confirms a page responds. Synthetic journeys go further — they replay a real multi-step flow, so you catch breakage in sign-in or checkout that a simple ping would miss.
Can I monitor pages behind a login?
Yes. Synthetic journeys let you script authenticated, multi-step flows such as sign-in, search, and checkout.
Does SentinelWeb check SSL certificates and domain expiry?
Yes. SentinelWeb tracks certificate validity and domain registration dates and warns you well before either lapses.
Can I see incident history and root cause?
Every incident is kept as a timeline — when it started, when it recovered, and the root-cause notes — so past outages stay easy to review.
Which site health checks are included?
Beyond uptime, SentinelWeb runs performance, security header, malware and Safe Browsing, and SEO indexability checks on monitored sites.
