Why You Need This
WordPress relies on WP-Cron for critical tasks like:
Publishing scheduled posts
Sending emails
Running backups
Processing orders (WooCommerce)
Updating plugins and themes
When WP-Cron fails silently, these tasks stop working. Cron Guard gives you visibility into your cron health and alerts you before problems become critical.
Multi-Site Management for Agencies
Managing cron across dozens of client sites? The Agency Dashboard (Agency and Agency Plus plans) brings every site’s cron health onto one screen. Connect each client site with a secure key, and your hub polls them on a schedule and on demand — showing health status, overdue and stalled hooks, the last successful run, and a 7-day uptime trend for each site, with a one-click link into any site’s own Cron Guard.
Because the hub polls each site over a secure REST endpoint, you still see the truth even when a client’s own WP-Cron has stopped — the exact failure you need to catch. Turn on the email digest to get a scheduled summary the moment any client site needs attention, so you don’t have to keep the dashboard open. No external service required; your hub is just another WordPress site running Cron Guard.
Need something client-facing? Generate white-label reports for any connected site — branded with your logo, agency name, and accent color — viewable on demand and printable straight to PDF from your browser, or emailed to each client automatically every month.
Onboarding lots of sites? Bulk-import them by pasting a list, or flip on self-enrollment so each client site registers itself with your hub using a shared token — no copying keys one at a time. Every stored connection key is encrypted at rest with a key derived from your site’s secret keys, so a database dump alone never exposes them.

External Cron Services (Referenced Only)
