Interval-based monitoring
Check every minute or every hour — you set the pace. Sentinel polls your sites on your schedule, every single time.
Instant email alerts
Get notified the moment a site goes down, slows down, or comes back up. No noise — only real status changes trigger alerts.
SSL certificate tracking
Never get caught by an expired certificate. Sentinel warns you when SSL is within your chosen number of days from expiry.
Response time thresholds
Define what "slow" means to you. Sites that exceed your response threshold are marked degraded — before your users notice.
Content verification
Make sure your page is serving the right content. Set expected text and get alerted if it ever disappears.
Multi-account
Every account gets their own isolated dashboard and settings. Your sites stay yours — no overlap with other users.
