For the technical stakeholder ### Expiry Thresholds & Renewal Tracking This is how it is wired. Read the SSL Monitoring documentation https://docs.uptimeify.io/monitoring/monitoring-types/ssl Handshake A full TLS handshake parses the leaf certificate, validity window and key on every check. Thresholds Warning 7 d Error at expiry warning fires 7 days before expiry by default, error at expiry, fully configurable per monitor. Validation The certificate is validated over the negotiated TLS connection on every handshake. Identity Hostname (CN / SAN) and certificate validity are matched against the monitored URL. Certificate Layer ## Cost Trust. Expired Certs. An expired certificate almost never surfaces on your side first. It surfaces when your client's browser turns red. Uptimeify warns you well ahead of time, with thresholds you set per monitor, so you renew before anyone hits a warning page. - **Staggered expiry thresholds**, so you split an early heads-up from a hard alarm instead of scrambling on the last day. - **Configurable per client**, so a short-lived shop certificate gets treated differently than a rarely-touched corporate domain. - **Renew before it burns**, so no client ever sees the "Not Secure" warning and calls you, instead of the other way around. For the technical stakeholder ### Chain of Trust & Hostname Logic This is how it is wired. Read the SSL Monitoring documentation https://docs.uptimeify.io/monitoring/monitoring-types/ssl Chain The leaf and every intermediate are resolved up to a trusted Root Certificate Authority. Hostname CN SAN every handshake checks the certificate covers the monitored host. Identity Common Name (CN) and Subject Alternative Name (SAN) are matched against the monitored host. Root store Validated against the system's CA trust store for real browser parity. Trust Layer ## We Check the Whole Chain. Validity Doesn't End at Expiry. A certificate that hasn't expired isn't automatically a trusted one. Miss an intermediate or chain up to a root nobody recognizes, and trust breaks on individual devices, often unnoticed. Uptimeify validates the full hierarchy from root CA down to your domain, and matches the hostname against the certificate on top. - **Root CA verification**, so every certificate provably traces back to a globally recognized root, not just to "some" signature. - **Complete chain resolution**, so a missing intermediate surfaces immediately instead of running on as apparently valid until a stricter client rejects it. - **Hostname matching**, so common name and subject alternative name line up exactly with the monitored URL, and no mismatch slips through. For the technical stakeholder ### Intermediate Diagnostics & SAN Matching This is how it is wired. Read the SSL Monitoring documentation https://docs.uptimeify.io/monitoring/monitoring-types/ssl Incomplete chain Detects missing intermediates that browsers patch via AIA but stricter mobile clients reject. SAN coverage Confirms every alias and subdomain is present in the certificate's SAN list. Error types expired mismatch incomplete-chain each failure is classified, not just flagged. Output Every failed audit returns the precise technical reason for fast remediation. Diagnostics Layer ## Don't Fix Themselves on Mobile. Incomplete-Chain Errors. The most common SSL trap isn't expiry. It's an incomplete chain: everything looks green on desktop, but trust breaks on certain Android devices or older clients. Uptimeify audits the server-side configuration and tells you exactly which link is missing, before your client messages you that "the site is broken on my phone." - **Intermediate diagnostics**, so you catch missing intermediate certificates that only trigger trust errors on specific devices and browsers. - **SAN mapping**, so every domain alias and subdomain is provably covered by the current certificate. - **Precise error logs**, so you know at a glance whether expiry, mismatch, or an incomplete chain was the trigger, instead of guessing. ### SLA & Contract Templates Service Level Agreement templates to define professional boundaries with your clients. ### Pricing Calculator Find the sweet spot for your care plans.

A hit in CN or SAN counts as a match; if the certificate covers the host through no entry, the check is flagged as a mismatch, kept separate from expiry and chain errors, so the error log carries the exact cause. Wildcard and multi-domain certificates resolve through their respective SAN entries. When does Uptimeify warn you about an expiring certificate? You set two thresholds: an early warning and a hard error alarm, by default the warning fires 7 days before expiry and the error at expiry, adjustable per monitor. That gives you enough lead time to renew and still a clear signal when it's genuinely tight. No client sees a "Not Secure" warning because a date slipped past you. Does Uptimeify check the full certificate chain or just the expiry date? The full chain. Uptimeify validates from the root CA through the intermediates down to your domain, and matches the hostname against the certificate on top. That catches exactly the failures a pure expiry check misses, like an incomplete chain that only breaks trust on certain devices. Does Uptimeify detect an incomplete certificate chain? Yes. Every handshake resolves the leaf and every intermediate up to a trusted root, including chains that browsers patch via AIA but stricter mobile clients reject. If an intermediate is missing, so the chain only breaks on some devices, you see it, instead of relying on an expiry date that still looks valid. Which regions does Uptimeify check certificates from? Polling runs from European monitoring locations, European infrastructure, with no US sub-processor with access to your monitoring data. That keeps the SSL check in the same sovereign stack as the rest of your monitoring and takes a whole discussion off the table in B2B and public-sector pitches. Can you deliver SSL monitoring to clients under your own brand? Yes. Certificate status flows into the same white-label dashboard and branded reports as the rest of your monitoring, under your own domain and logo. Your client sees your service proactively catching an expiry date, not a tool running in the background.
