Uptime monitoring and attack surface management in one platform, so you're first to know when a site goes down or a door is left open.
3 monitors free forever · no credit card · 60-second setup
Monitor every surface your customers touch, watch the certificates and DNS behind them, and see your whole external attack surface the way an attacker would.
Explore the platformHTTP/S, TCP, ping, and keyword checks from 300+ locations, as often as every 10 seconds.
Run real-browser flows like login and checkout, and catch breakages a status code never would.
Certificate, domain, and DNS expiry tracked to the day, with warnings weeks ahead.
Branded, hosted status pages that update themselves and turn incidents into trust.
RapidCheck maps your entire external footprint, then watches it for exposure. Forgotten subdomains, open ports, weak TLS, and shadow IT surface here, not in a breach report.
Paste a URL or import your whole stack. Sites, APIs, ports, certificates, DNS records, all in one place.
RapidCheck probes from 300+ edge locations and cross-confirms failures across regions to kill false alarms.
Sub-100ms alerts to your tools of choice, plus a live status page your customers can trust.
A single failing probe means nothing. RapidCheck verifies every incident across multiple continents, so a regional blip never drags you out of bed, and a real outage never slips by.
We cut our mean-time-to-detect from 22 minutes to under one. RapidCheck paged us before a single customer noticed.
Be the first to know, not the last. Monitor your uptime and your attack surface free, no credit card required.
