Masscan
Mass IP port scanner
Masscan is an Internet-scale port scanner, able to scan the entire Internet in just 6 minutes or less. It's considered the fastest port scanner and is similar to the famous port scanner nmap, and like port scanners scanrand and unicornscan it uses asynchronous transmissions. However, it is more flexible when it comes to arbitrary port and address ranges. Masscan not only detects when ports are open, it can also check banners. And while it is useful for smaller, internal networks, it's designed with the entire internet in mind. Do take note however that Masscan uses its own custom TCP/IP stack, so anything other than a simple port scan could cause conflict with the local TCP/IP stack unless certain configurations are done. -

RustScan
The Modern Port Scanner
The Modern Port Scanner. Find ports quickly (3 seconds at its fastest). Run scripts through our scripting engine (Python, Lua, Shell supported). Scans all 65k ports in 3 seconds. Full scripting engine support. Automatically pipe results into Nmap, or use our scripts (or write your own) to do whatever you want. Adaptive learning. RustScan improves the more you use it. No bloated machine learning here, just basic maths. The usuals you would expect. IPv6, CIDR, file input and more. Automatically pipes ports into Nmap. RustScan is a modern take on the port scanner. Sleek & fast. All while providing extensive extendability to you. Not to mention RustScan uses Adaptive Learning to improve itself over time, making it the best port scanner for you. Speed is guaranteed via RustScan. However, if you want to run a slow scan due to stealth that is possible too. We have tests that check to see if RustScan is significantly slower than the previous version. -

UDPStressTest
A Desktop app for network stress testing, TCP-Ping and icmp ping.
Easy to use GUI app. *It reads your active and Up NIC and gets some info about it. * You can see your machine IP Address, gateway, subnet mask. * You can ping any ip address you want and get measure of TTL. * It gets the available range of IP's in your local network. * When you start the test you see testing throughput as a graph against time also total size of packet sent in (MB). *You can use it as DOS attack tool. *Every action done on the app is logged in XML file as data source (only stress test + ping). *TCP-Ping is a perfect way to discover network devices which active firewall to ignore ping packets or you can use it as TCP port scanner to check your network security. *Stress test speed graph can be exported as image easily. *Searching log files for certain data is also integrated to app. *Exporting search results as static HTML page. -
