Five site monitors. One pane of glass.
Uptime, SSL expiry, DMARC email authentication, Google Business Profile health, and search indexing — 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
Cloud checks every 5 minutes. Get alerted the instant a site goes down — before your customers notice.
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.
GBP Health Monitoring
Track your Google Business Profile health score and optimisation status so the local listing stays strong.
Search Indexing
Monitor which pages Google has actually indexed and surface coverage gaps that quietly cost you traffic.
Everything In One Pane
Uptime, SSL, DMARC, GBP and indexing together — the stack agencies normally stitch from UptimeRobot, EasyDMARC and more, for one price.
