Technical details

UDP is a transport layer protocol (the same as TCP) mainly used in network services such as DNS, NTP, DHCP, RTSP, TFTP, and others.

Even though UDP services are less popular than TCP services, having a vulnerable UDP service exposes the target system to the same risk as having a vulnerable TCP service. Hence, discovering all open UDP ports is important in a penetration test for achieving complete coverage of the security evaluation.

Use Cases for UDP Port Scan

Network Penetration Testing

The scanner is helpful for quick port scans but also for lengthy scans which can take multiple hours. The results are accurate since our servers have direct Internet connection. Furthermore, the scanner is optimized for best performance and quality results.

Security Self-Assessment

Check if your servers exposed to the Internet have unnecessary open UDP ports. By also looking at the service versions, you can find which server software is outdated and needs to be upgraded.

Asset Inventory

You can scan IP addresses to map the live hosts and UDP services exposed to the Internet. Find which machines are old and could be used by attackers to break the perimeter and gain access to the internal network.
