Uptime Monitoring for Agencies
Keep every client site online and prove it. Monitor uptime across your whole portfolio from one dashboard, send branded reports at renewal, and hear about an outage before the client picks up the phone.
Why agencies choose Sentinel
Uptime is part of what clients pay you for
When a client's site goes down, it's your reputation on the line, not just theirs. Sentinel watches every site you manage, confirms outages across regions, and gives you the reports and status pages to show the value of the retainer.
- Catch downtime before your client does
- Prove uptime with branded client reports
- Measure real uptime against SLA targets
Built for client work
Everything you need to keep clients online
Per-client uptime reports
Generate branded, scheduled uptime reports for every client so each retainer renewal comes with proof you kept their site online. Available on the Business plan.
Branded status pages
Give each client a status page so they self-serve uptime instead of emailing you during every blip. Custom domains start on Pro.
SLA tracking
Measure real uptime against the 99.9% or 99.95% targets in your service agreements, and know where every account stands before the client asks.
One portfolio dashboard
See uptime, SSL, DNS and response time for every client site in a single view. No more logging into a different tool for each account.
Team roles & handoffs
On Pro and Business, invite your team as admins, editors or viewers, and route incidents to whoever is on point so downtime never waits on one person.
Alerts before clients notice
Email, SMS, Slack, Discord, Telegram and webhook alerts the moment a site drops, confirmed across regions so you're not chasing false alarms.
FAQ
Agency uptime monitoring questions, answered
What is uptime monitoring for an agency?
Uptime monitoring continuously checks whether your clients' websites are reachable and alerts you the moment one goes down. For an agency, it means watching every client site from one account so you find out about an outage before the client does, and can show you keep their sites online.
Don't the hosting companies already monitor these sites?
They monitor their servers, for their own SLA, and their alerts go to their ops team rather than to you. When a client asks how long their site was down, the host's word is a self-report. An independent monitor gives you a third-party timeline you can put in a report. It also catches what host monitoring can't see: expired certificates, lapsed domains, DNS mistakes, and pages that break while the server stays up.
Can I monitor all my client sites from one account?
Yes. Sentinel is built for agencies to monitor many client sites from a single dashboard, so you don't juggle separate tools or logins per client. Uptime, SSL, DNS and response time for the whole portfolio live in one view.
Can I prove uptime to clients?
Yes. On the Business plan you can send scheduled, branded uptime reports per client. Every plan includes a status page, and custom domains start on Pro. Both make it easy to demonstrate the value of a care plan or retainer at renewal time.
How fast are uptime checks?
Checks run as often as every 15 seconds on Business, from fifteen global regions, with an outage confirmed by consensus before you're alerted. That filters out false alarms from a single bad region while still catching real downtime quickly.
How will my team be alerted to downtime?
Alerts can be sent via email, SMS, Slack, Discord, Telegram and webhooks, so incidents land in whatever channels your team already uses, and you can choose which channels each monitor alerts.
Is there a free plan or trial for agencies?
Yes. There's a free plan to start with, and paid plans include a 14-day free trial. You can cancel anytime.
