How this service works
Is TCP port 514 (syslog) 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 syslog without running a scanner. $0.01 per check.
Output
Returns the status of TCP port 514 on the target host — one of open, closed, or filtered — along with the TCP connect time in milliseconds. If the host is behind Cloudflare's edge, the result is flagged as inconclusive because Cloudflare's infrastructure answers the connection attempt on behalf of the origin.
Example use cases
Syslog exposure audit before deployment
“Before I go live, can you check if port 514 is open or filtered on my server at 198.51.100.22? I need to make sure syslog isn't accidentally exposed to the internet.”
Security sweep of third-party vendor IP
“I need to know if TCP port 514 is open on our vendor's host at 203.0.113.88 — check whether their syslog port is publicly reachable.”
Incident response — unexpected syslog traffic
“We're seeing weird inbound traffic and I suspect port 514 got opened by mistake on 192.0.2.15. Can you check right now if that syslog port is actually open from the outside?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/ip/port/514?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, passive check of whether TCP port 514 (syslog) is exposed on a host without deploying your own scanner or running nmap. Ideal for security audits, compliance checks, or pre-deployment exposure verification where you want a lightweight, remote perspective from Cloudflare's edge. Not suitable for hosts behind Cloudflare CDN, where results will always be inconclusive.
Side effects
- Cloudflare-fronted hosts always return inconclusive regardless of actual port state
- Connection timeout may cause the result to be reported as filtered rather than closed
- Invalid or non-routable IP addresses may return an error or filtered status
- Rate limiting or network-level blocks at Cloudflare's edge may affect accuracy
