On-call alerting for IT support firms and MSPs

Your clients' monitoring tools raise alarms at 3am. Tocsin makes sure the right engineer on your team actually hears about it, and keeps escalating until someone takes it.

No card needed for the trial. Tocsin is a product of Espresso Group Ltd, a UK company.

The problem with alerts in a shared mailbox

• Alerts land in a mailbox or a chat channel and everyone assumes someone else has seen them.
• Out-of-hours cover lives on one person's phone and a spreadsheet nobody updates.
• The client rings in before you know there is a problem.

How it works for an MSP

1. Add your engineers and your rota. A schedule for each team, such as service desk out of hours, networks or cloud, with who is on call each week and overrides for holidays and swaps. Out-of-hours partners and contractors can sit on a rota too.
2. Connect each client's monitoring. Give each client or tool its own Tocsin email inbox or webhook. Your monitoring, backup and uptime tools send urgent alerts to it.
3. Route by client and severity. A critical alert for a client on a 24/7 contract goes to the on-call engineer. A low-severity warning waits in the dashboard.
4. Escalate until it's handled. Text first, a phone call two minutes later, then the team lead. The engineer replies "ACK" and it stops.

Connecting client tools

Tocsin accepts alerts from anything that can send an email or a webhook, including tools like Grafana, Datadog, Zabbix, PRTG, Uptime Kuma, UptimeRobot, CloudWatch and Azure Monitor, so there is nothing to install on a client's network. Words like "critical" or "P1" in an email subject set the severity, and repeat alerts about the same problem are merged. Each email inbox accepts mail only from the senders you list.

Product names belong to their owners. Tocsin is not affiliated with or endorsed by them. It receives their standard email and webhook notifications.

Why MSPs choose it

• Right engineer, right client. Route by client and severity instead of paging everyone.
• It does not stop at the first try. Alerts escalate by text, then phone, then the next person.
• A clear record. Every alert shows each text, email and call and what happened. Useful when a client asks what happened and when.
• No app for your engineers to install. Texts and calls work on any mobile.
• Pay for what you send. A flat plan price for the organisation, and credits only for texts and calls.

Running several clients

Today all your clients' alerts go through your own Tocsin organisation, kept apart by inbox and by route. Each organisation can have up to 20 email inboxes. We are planning a partner programme for firms that want a separate organisation per client under one login, with partner pricing. If that matters to you, tell us what you need and we'll build it around real use.
