Expiry Alerts

Three Warnings Before It's Too Late

Certificates expire silently. FlareWarden sends alerts at three configurable thresholds so your team has time to renew before visitors see browser warnings.

30 days: Warning — plenty of time to plan renewal
14 days: Urgent — time to act if auto-renewal failed
7 days: Critical — immediate attention required
Customizable: adjust all thresholds from your account settings
Change Detection

Know When Certificates Rotate

FlareWarden compares certificate fingerprints on every check. When a certificate is renewed or replaced, you get notified with full details of both the old and new certificate.

Fingerprint comparison: SHA-256 hash detects any change
Issuer tracking: alerts when your CA changes (e.g. Let's Encrypt to DigiCert)
Certificate history: full record of every certificate seen on your domain
Flip-flop detection: handles load balancers rotating between certificates
Certificate Transparency

Discover Certificates You Didn't Know About

FlareWarden periodically scans Certificate Transparency logs for certificates issued for your domain. If someone issues a certificate for your domain without your knowledge, you'll know.

Subdomain discovery: find certificates for subdomains you might have missed
Unauthorized detection: catch rogue certificates issued for your domain
One-click tracking: enable monitoring for discovered subdomains directly from your dashboard

How It Works

SSL monitoring is automatic. There are no extra monitors to create or settings to enable.

1

Add an HTTPS Monitor

Create an uptime monitor for any HTTPS URL. Smart Setup can do this for you automatically.

2

SSL Tracking Starts

FlareWarden begins tracking the certificate immediately — expiry, fingerprint, issuer, chain, and TLS version.

3

Get Alerts When It Matters

Expiry warnings, change notifications, and CT discovery alerts arrive via email or webhook.

Frequently Asked Questions

No. SSL monitoring is automatic for every HTTPS uptime monitor. When you create an uptime monitor for an HTTPS URL, FlareWarden begins tracking the certificate immediately. There is no extra setup or cost.

Yes. The default thresholds are 30 days (warning), 14 days (urgent), and 7 days (critical), but you can change all three from your account settings. Each team member can also control which SSL notifications they receive.

Certificate Transparency (CT) is a public log of all SSL certificates issued by certificate authorities. FlareWarden periodically scans these logs to discover certificates issued for your domain — including subdomains you might not be monitoring. This helps you catch unauthorized certificate issuance and find subdomains that need monitoring.

No. FlareWarden supports multi-certificate tracking. When your server presents a different valid certificate, you can mark it as "expected" from your dashboard. The system handles flip-flopping between multiple certificates without triggering false change alerts.

Yes. SSL certificate monitoring is included on every plan, including the free plan. Any HTTPS uptime monitor you create automatically gets full SSL tracking — expiry alerts, change detection, and certificate details.
