An Expired Certificate Kills Trust Instantly
One expired SSL certificate and browsers block your visitors with a red "Not Secure" warning — destroying trust, tanking SEO rankings, and wiping ad revenue in seconds. DrMonitor watches your certificates 24/7 and alerts you weeks before expiry, so you never get caught off guard.
Start for freeGet warned weeks before your certificate expires
SSL certificates expire quietly. Auto-renewal tools fail. Renewal reminders get buried in email. DrMonitor tracks the exact expiry date of every certificate across all your sites and sends you staged alerts — at 30 days, 10 days, and 1 day — so you always have time to renew before visitors see a browser warning.
- Staged alerts at 30, 10, and 1 day before certificate expiry
- Track multiple certificates across all your domains in one dashboard
- Catches auto-renewal failures before they cause a real outage
- Alerts via email, SMS, and Telegram — never miss a critical renewal
Catch invalid, mismatched, and revoked certificates fast
Expiry is just one way SSL can break. A misconfigured renewal, a wrong domain, a revoked certificate, or a TLS downgrade can all trigger browser security warnings — blocking visitors without any obvious outage signal. DrMonitor validates your certificate on every check so no failure goes unnoticed.
- Detects expired, self-signed, mismatched, and revoked certificates
- Identifies TLS/Certificate errors as a distinct issue type
- Instant alert the moment a certificate becomes invalid
- Full incident log — start time, duration, and resolution recorded
A broken certificate costs you traffic, trust, and rankings
Google uses HTTPS as a ranking signal. When your certificate expires or becomes invalid, your site gets flagged as "Not Secure" — visitors bounce, Google crawlers may deindex pages, and AdSense revenue drops the moment fewer pages load. DrMonitor monitors TLS version and certificate health so your site stays secure, trusted, and visible in search.
- TLS version detection — flags outdated TLS 1.0 / 1.1 as a security risk
- Protects SEO rankings — HTTPS is a direct Google ranking factor
- Prevents "Not Secure" browser warnings that drive visitors away
- Safeguards ad revenue — secure pages serve ads; flagged pages don't
