How this service works
Is TCP port 22 (SSH) open on a host? Attempts a connection from Cloudflare's edge and reports open/closed/filtered with the connect time; Cloudflare-fronted hosts are reported as inconclusive because their edge answers for them. Exposure checks for SSH without running a scanner. $0.01 per check.
Output
Returns the status of TCP port 22 on the target host as one of: open, closed, filtered, or inconclusive (when the host is Cloudflare-fronted and Cloudflare's edge answers on its behalf). For open ports, includes the TCP connect time in milliseconds.
Example use cases
SSH exposure audit on production server
“Check whether port 22 is open on my server at 203.0.113.45 — I need to know if SSH is accidentally exposed to the internet.”
Pre-deployment security check
“Before I hand off this VM at devbox.mycompany.com, can you verify that SSH on port 22 is closed or filtered? It shouldn't be publicly reachable.”
Incident response SSH reachability check
“We think an attacker may have re-enabled SSH on compromised host 198.51.100.12 — can you quickly check if port 22 is open right now?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/ip/port/22?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, passive SSH exposure check on a single host without running a local port scanner or installing any tools. It is ideal for security audits, pre-deployment checks, and incident response triage where you want a third-party (Cloudflare-edge) perspective on port 22 reachability. Prefer this over general-purpose scanners when you need a low-cost ($0.01), single-port, single-host check with no setup.
Side effects
- Host is Cloudflare-fronted: result is returned as 'inconclusive' because Cloudflare's edge intercepts the connection
- Connection attempt times out: reported as filtered
- Invalid or unresolvable hostname: likely returns an error or closed status
- Host behind a firewall that silently drops packets: reported as filtered rather than closed
- Transient network issues from Cloudflare's edge may cause false negatives
