Every site monitor. One pane of glass.
Uptime, SSL expiry, DNS, DMARC email authentication and the Google Business Profile listing — every signal that tells you a site is healthy, watched together and alerting you the moment something breaks. The tools agencies normally buy separately, unified per client.
Everything included in Sentinel
Powerful features designed for the way you actually work.
Uptime Monitoring
Checks every 15 minutes, alerting after repeated failures rather than one blip — so you hear about a real outage before your customers do.
SSL Certificate Watch
Track certificate expiry across every domain and get warned well before a cert lapses and breaks the site.
DMARC Analysis
Ingest DMARC XML reports and visualise email authentication pass/fail rates — spot spoofing and protect deliverability.
Google Listing Watch
A weekly check of each Google Business Profile: marked closed, website link pointing elsewhere, hours or phone missing, a rating drop. The full optimisation score comes with ModusOp SEO.
DNS Health
Check the records a site and its email depend on, and spot the misconfiguration before it takes something down.
Everything In One Pane
Uptime, SSL, DNS, DMARC and the Google listing together — the stack agencies normally stitch from UptimeRobot, EasyDMARC and more, for one price.
