Monitoring for WordPress agencies, without the plugin.
ManageWP and MainWP watch WordPress from the inside. Pleenx watches from the outside — the same vantage point as your client's actual visitors. No plugin to install, no admin credentials to manage, no extra attack surface to maintain.

WordPress care plans built on plugin-based monitoring (ManageWP, MainWP, iThemes Sync) catch what happens inside WordPress. Pleenx catches what happens around it — SSL silently expiring, domain auto-renewal failing, DNS drift after a host migration, MX record changes that break the client's email. Use them together; we don't compete on plugin update management.
What actually breaks on WordPress sites.
SSL expired silently
Let's Encrypt auto-renewal fails when DNS changes during a host migration. The WordPress plugin can't see the TLS handshake — only an external probe catches it.
Domain didn't auto-renew
Card on file declined at the registrar. WHOIS expiry passes. The site is offline for the weekend before anyone notices. Plugin-based monitoring can't see registrar state.
Plugin update broke the homepage
WooCommerce update changed the checkout flow markup. Synthetic probe asserts expected text on the page and catches the regression within an hour.
DNS hijack after staff offboarding
Former employee still had registrar access. NS records changed overnight. Daily DNS snapshot diff catches the change before mail starts going to attacker mailbox.
WP staging accidentally indexed by Google
Junior dev deployed staging settings to production. noindex shipped to live. SEO probe catches the meta tag drift the same morning.
WordPress sending mail from blocked IP
Host's shared IP got blacklisted. Newsletter goes to spam. Email-auth probe catches the SPF chain breakage that signaled it.

WordPress care plan checklist 2026: what to actually monitor (and what to drop)
Most agency WordPress care plan templates carry over a list of monitors that mattered in 2014 and ignore four things that take down clients in 2026. The current-state checklist plus the items we cut from ours.
4 min · ssl · monitoringWhat breaks when an SSL cert expires (and how to catch it before your client does)
Field guide to silent SSL expiry: what fails, what alerts you do and don't get, and how to catch the 30/14/3-day windows reliably.
7 min · whois · domainsDomain didn't auto-renew: 7 reasons your client's site went dark (and how to catch each one)
WHOIS auto-renewal fails quietly — until the WHOIS expiry date passes and the registrar parks the domain. The seven failure modes we keep seeing across agency portfolios, with detection commands and the alert thresholds that actually matter.
