Frequently asked questions
What is a port scan?
A port scan checks which network ports are open on a server or device. Open ports run services that accept connections — web servers, databases, email, remote access. Attackers scan for open ports to find potential entry points. Knowing which ports are open on your infrastructure is the first step in reducing your attack surface.
How often does SeguriScan scan my ports?
Weekly scheduled scans with change detection. Results appear in your dashboard within 24 hours.
Does port scanning affect my servers?
Our scans are non-intrusive and designed for production environments. They simulate what an external attacker would see — no exploitation, no disruption.
What do I do when open ports are found?
Each finding includes a severity rating and fix recommendations. Close unnecessary ports, update services, and restrict access to sensitive ports.
