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.

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.

Branded status pages

Give each client a status page on your own domain so they self-serve uptime instead of emailing you during every blip.

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

Invite your team, scope who sees which clients, and route incidents to whoever is on point so downtime never waits on one person.

Alerts before clients notice

Email, SMS, Slack, Discord 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.

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. You can send scheduled, branded uptime reports per client and give each one a status page on your own domain. 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 30 seconds on higher plans, from four 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 and webhooks, so incidents land in whatever channels your team already uses, and you can route different clients to different people.

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.
