    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

    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.
