Dive deeper: how the live probe + CT works · why shorter certs are a problem

// CAPABILITIES

SSL + Uptime monitoring. One focused tool.

▣

LIVE TLS PROBE

Real handshake on :443. Reads issuer, SAN, chain, TLS version — not just what CT says was issued.

◉

UPTIME MONITORING (UptimeRobot-style)

Any HTTP method, full path/route, expected status codes, keyword match in body. Configurable interval, pause/resume, full history.

◈

CT MONITORING + NEW CERT ALERTS

Certificate Transparency logs + real alerts the moment a new certificate is issued for your domain.

⚑

ALERTS ON EVERYTHING

Email, Slack, Webhook (SMS on paid, Teams etc via webhook). 30/14/7/1 for SSL. Immediate on uptime down. Idempotent.

⛨

PRIVATE & INTERNAL CERTS

Monitor anything your probe can reach (internal networks via tunnel supported).

✦

FREE TIER + API EARLY

10 SSL + 10 uptime monitors free forever. Full webhooks + REST API from Starter at $15/mo.
