Every check you need
One platform for every endpoint
From a public web app to an internal database port, PulseGuard watches it from around the world.
HTTP & HTTPS
Status codes, response body keywords, redirects and latency — checked from every region.
SSL certificate
Expiry, chain and validity monitoring with warnings 30, 14 and 7 days out — never get caught by an expired cert.
DNS records
Watch A, AAAA, CNAME, MX and TXT records for unexpected changes or propagation failures.
TCP ports
Confirm databases, mail and custom services are accepting connections on any port.
Ping / ICMP
Reachability and round-trip latency for hosts, routers and bare-metal infrastructure.
Keyword & content
Assert that a page contains (or doesn't contain) specific text — catch soft failures a 200 hides.
Alerts, without the noise
Get paged for real incidents — not blips
PulseGuard confirms failures across regions, then an AI engine deduplicates the flood of related signals into a single incident before it ever reaches you. Every incident gets a live timeline and auto-updates your status page.

How it works
Live in under two minutes
Add a monitor
Paste a URL or host and pick a check type — HTTP, SSL, DNS, TCP or Ping. Setup takes under a minute.
We watch from everywhere
PulseGuard probes your endpoint every 30 seconds from 15 regions and records latency, status and SSL health.
You hear about it first
When several regions agree something's wrong, AI-deduplicated alerts reach your team and your status page updates automatically.
FAQ
Monitoring questions, answered
How often does PulseGuard check my endpoints?
As often as every 30 seconds on paid plans (and every few minutes on the free plan), from 15 global regions. An outage is only confirmed when multiple regions agree, which prevents false alarms from a single flaky probe.
What can it monitor?
HTTP/HTTPS, SSL certificate expiry and validity, DNS records (A, AAAA, CNAME, MX, TXT), TCP ports, Ping/ICMP, and page content/keyword assertions.
How do alerts avoid being noisy?
Two ways: configurable consecutive-failure thresholds before anything fires, and an AI deduplication engine that collapses related signals into a single incident — typically cutting alert volume by up to 90%.
Which notification channels are supported?
Email, Slack, Discord and webhooks on all plans, plus PagerDuty and escalation policies on Pro and Business.
Will I get warned before my SSL certificate expires?
Yes. PulseGuard warns you 30, 14 and 7 days before expiry, and alerts immediately if a certificate becomes invalid or the chain breaks.
