What it is
Ports are the numbered endpoints a server listens on, each conventionally tied to a service: 80 for HTTP, 443 for HTTPS, 22 for SSH, 21 for FTP. This check reports which of the common ones accept a connection.
Why it matters
Anything listening is something that can be attacked, so an unexpected open port is worth explaining. Database ports, admin interfaces and remote access services exposed straight to the internet are the usual findings.
How this assessment works
Skopeon Labs queries public infrastructure signals and authoritative network protocols directly from external sensor nodes. All evaluations are completely non-invasive and agentless, assessing observable configurations without sending malicious payloads or disrupting service.
Operational Scope & Limitations
This check evaluates public perimeter responses observable at the time of inquiry. Endpoints protected behind third-party reverse proxies or CDNs reflect the edge configuration of the proxy layer.
