Proactive TLS Validation & Expiration Tracking
Availability monitoring for Russian IT teams. Continuous HTTPS endpoint verification with automated renewal workflows.
Expiration Tracking
UptimeGuard continuously probes your domains every 15 minutes to verify TLS handshake success and extract Not After dates.
We track the full lifecycle of RSA-2048, ECDSA P-256, and P-384 certificates issued by Let's Encrypt, GlobalSign, DigiCert, and Sectigo. Historical retention covers 18 months of validity windows, allowing your DevOps team to forecast renewal cycles and avoid unplanned downtime. Every check logs the exact remaining days, issuer CN, and SAN coverage for audit compliance.
Chain Validation
A valid leaf certificate is useless if the intermediate or root trust path breaks. UptimeGuard reconstructs the full X.509 chain on every scan.
Our validators verify OCSP stapling responses, check CRL distribution points, and flag mismatched intermediate certificates within 200 milliseconds. We detect common misconfigurations such as missing cross-signatures, expired root anchors, and incorrect SNI routing. If the chain depth exceeds three levels or contains untrusted intermediate CAs, the endpoint status immediately shifts to degraded.
Alerts & Notifications
Never miss a renewal deadline. UptimeGuard delivers tiered warnings through email, Slack, Telegram, and PagerDuty webhooks.
Configure custom thresholds or rely on our industry-standard notification schedule. Teams receive automated digests when certificates approach critical windows, ensuring your SREs have ample time to execute ACME challenges or coordinate with internal PKI admins.
30-Day Warning
Initial notification with remaining days, issuer details, and recommended renewal steps. Delivered to primary administrators via configured channels.
14-Day Escalation
Priority alert routed to secondary contacts with automated ticket creation in Jira or ServiceNow. Includes direct links to certificate management consoles.
7-Day Critical
Urgent broadcast with one-click renewal links and fallback DNS override instructions. Triggers SMS fallback if primary channels remain unacknowledged.
