How to check if Zscaler is down?

Why use IsDown to monitor Zscaler instead of the official status page?

Because IsDown is a status page aggregator, which means that we aggregate the status of multiple cloud services. You can monitor Zscaler and all the services that impact your business. Get a dashboard with the health of all services and status updates. Set up notifications via Slack, Datadog, PagerDuty, and more, when a service you monitor has issues or when maintenances are scheduled.

How IsDown compares to DownDetector when monitoring Zscaler?

IsDown and DownDetector help users determine if Zscaler is having problems. The big difference is that IsDown is a status page aggregator. IsDown monitors a service's official status page to give our customers a more reliable source of information instead of just relying on reports from users. The integration allows us to provide more details about Zscaler's Outages, like incident title, description, updates, and the parts of the affected service. Additionally, users can create internal status pages and set up notifications for all their third-party services.

Compared to Zscaler's official status page IsDown offers way more control and visibility over what's going on.

  1. Monitoring not only Zscaler's official status page but also 4,522+ other services
