The call you never want to get

Every agency has been there. SiteBrief makes sure it never happens again.

"Hey, your client's site has been down for 2 hours"

From your biggest client. On a Friday at 5pm.

Most common

SiteBrief alerts you in under 2 minutes — before anyone else notices.

"Why are we paying a retainer if you don't notice when our site is broken?"

Client's SSL expired. Their checkout showed security warnings for 3 days.

Most expensive

SiteBrief warns you 30 days before any SSL or domain expires. Automatically.

"Can you show me what uptime we've had? I need to justify this to my boss."

No report. No data. Awkward silence on the call.

Most awkward

Monthly PDF reports sent automatically. Data ready before clients ask.

Common questions

How many client sites can I monitor?
The Agency plan covers unlimited sites. Organise them by client, environment (staging vs production), or tag — however your team works.
Can clients see their own status page?
Yes. Each client gets a status page at their own custom domain — status.theirclient.com. You control what's shown. They see uptime, incidents, and 90-day history.
Can I send reports to clients automatically?
Yes. SiteBrief generates PDF reports with uptime %, incident history, SSL and domain status. Perfect for monthly retainer check-ins.
How quickly will I know when something goes down?
Within 1–2 minutes. We check every 60 seconds, use dual-confirmation to rule out false alarms, then alert via Slack, email, SMS, or phone.
Can my whole team use it?
Absolutely. Add members with role-based access. Your developers get paged, account managers can pull reports — everyone sees exactly what they need.
Do I need to install anything on client sites?
Nothing. No plugin, no code snippet, no client cooperation needed. If it has a URL, we can monitor it.
