How this service works
Is TCP port 102 (S7comm) 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 S7comm without running a scanner. $0.01 per check.
Output
Returns whether TCP port 102 is open, closed, or filtered on the target host, along with the connection time in milliseconds. If the host is Cloudflare-fronted, the result is marked inconclusive because Cloudflare's edge answers on the host's behalf.
Example use cases
ICS exposure audit for a PLC
“I need to know if TCP port 102 is open on 10.0.0.25 — that's a Siemens PLC I manage and I want to verify whether S7comm is reachable from outside our network.”
Security sweep for internet-facing OT
“Can you check if port 102 is open on plc.myindustrialsite.com? I'm worried our SCADA equipment might be accidentally exposed to the internet.”
Pre-deployment infrastructure check
“Before we go live, can you verify whether port 102 is open or filtered on 203.0.113.77? We need to confirm our S7comm service is actually reachable.”

Endpoint
GEThttps://ip.intel.rallylive.ca/ip/port/102?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, scan-free check of S7comm (TCP port 102) exposure on a single host without deploying a network scanner. Ideal for security audits, compliance checks, or monitoring ICS/SCADA device reachability from an external vantage point. Not suitable for batch scanning or when targets are known to be Cloudflare-fronted.
Side effects
- Cloudflare-fronted hosts return inconclusive status rather than true port state
- Filtered ports may be indistinguishable from closed depending on firewall behavior
- Timeouts may occur for very slow or unreachable hosts
- Host behind NAT or private IP ranges may return unreachable errors
- DNS resolution failure if hostname is invalid or unresolvable
