Dead man's switch for scheduled jobs
Know the moment a job goes quiet.
Your backup, cron job or batch pings Silens when it finishes. Miss a ping — or send a bad result — and you hear about it. The alarm fires on the signal that didn't arrive.
Start free — no cardThe trace is the healthy job. The flatline is what Silens is built to catch.
Why it's not just another cron ping
| Verify the result, not just the run | Send a number with your ping — row count, backup size, record age — and Silens alarms if it drifts out of the range you set. Catches the "backup ran but produced a 0-byte file" case. |
| Duration anomaly detection | Silens learns how long a job normally takes and warns when a run suddenly takes far longer — an early signal before it fully fails. |
| Windows-first, not just cron | Every check gives you a ready-to-paste snippet for Task Scheduler (PowerShell), cron, Python and curl. No translation needed. |
