SSL monitoring for Netlify-hosted sites
Netlify provisions Let's Encrypt certs free and renews them every 90 days — but DNS verification can quietly fail on certain TLD/DNS-host combinations. ManageCert hits the edge daily and pings you with weeks of headroom.
Classic Netlify SSL gotcha: you change registrar or update an A record, the next 90-day LE renewal silently fails verification, and 80 days later you have an expired cert. ManageCert is the independent observer that catches that 50 days before the user does.
Why ManageCert for Netlify sites
Catches Let's Encrypt renewal failures
The Netlify dashboard sometimes shows 'cert active' even when the public-facing cert is days from expiry. We hit the actual port 443 and report what visitors will see.
Branch deploys + custom domains
Add every custom domain you serve — production, staging, branch deploys, sales-page subdomains. Each tracked independently.
DNS-change alerts
If someone fat-fingers a CNAME in Netlify DNS, you hear about it the same day. Mid-night DNS flips are how mail and auth quietly break.
SSL, domain expiry, DNS — daily, across all your domains.
SSL certificates
Expiry, issuer, SANs, chain validity, hostname match. Alerts at 30/14/7/1 days, plus immediate if invalid.
Domain registration
RDAP + WHOIS lookups daily. Alerts at 60/30/14/7 days. Catches lapsed-domain → squatter before it happens.
DNS records
A/AAAA/MX/CNAME/TXT/NS snapshot + diff. Catches mid-night MX flips before mail breaks for a week.
