Port Authority - Port Scanner 2.4.5-free

A versatile tool focused on systems and security, Port Authority stands out as a rapid port scanner. It enhances network exploration by swiftly identifying hosts and providing valuable network details about your device and other hosts.

Among the swiftest port scanners with host discovery available, Port Authority excels in completing host discovery within just 5 seconds. When dealing with devices that drop packets, scanning 1000 ports takes approximately 10 seconds. In cases where devices reject packets, a full scan of all 65,535 ports takes less than 30 seconds.

Features:

• Highly threaded operation for expedited results
• Local area network (LAN) host discovery
• Public IP detection
• MAC address vendor identification
• LAN/WAN TCP port scanning for hosts
• Custom scans for specific port ranges
• Direct access to discovered HTTP(S) services through a browser
• Efficient service fingerprinting to determine SSH/HTTP(S) server type and version
• DNS record lookups supporting nearly all record types
• Wake-on-LAN functionality for hosts on the LAN

The speed of scans is achieved through the application's utilization of threading, allowing for efficient processing of operations. By optimizing resource-intensive UI updates during scans, the application ensures fast and effective performance.

If encountering crashes while scanning extensive port ranges, adjusting the port scan thread count in the settings can help prevent out-of-memory exceptions. Similarly, modifying host scan timeout settings can improve device responsiveness and accuracy in detecting LAN hosts.

To enhance your experience with the application, it is advised to adjust connection timeout settings when performing WAN scans to accommodate varying network conditions, such as mobile carrier restrictions or network latency issues.
