IsDown and DownDetector help users determine if Duo Security 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 Duo Security'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 Duo Security's official status page IsDown offers way more control and visibility over what's going on.
We aggregate the status of all the services you've dependent on. Have a clear view of all your dependencies and their status.
We send you an alert whenever we detect a new incident from official sources or crowdsourced reports. You will be the first to know when there is an issue with your dependencies.
Aggregate all the status information in one status page (public or private). You can also send the information and alerts to your team's tools, such as Slack, Datadog, Microsoft Teams, PagerDuty, and more.
