Armitage vs Responder: Which Kali Linux Tools tool is Best in 2025?

Armitage is a dynamic open-source GUI for the Metasploit Framework, pre-installed in Kali Linux (version 20221206), tailored for penetration testers and red teams. This Metasploit GUI tool for ethical hacking simplifies complex workflows by visualizing targets, recommending exploits, and automating post-exploitation tasks. With a 10.95 MB footprint and team server for multi-user collaboration, Armitage is a top collaborative penetration testing tool for cybersecurity experts, harnessing Metasploit’s vast exploit library for streamlined security assessments.

Responder is a robust, open-source tool designed for network penetration testing, specializing in Link-Local Multicast Name Resolution (LLMNR), NetBIOS Name Service (NBT-NS), and Multicast DNS (mDNS) poisoning. Pre-installed on Kali Linux, Responder enables cybersecurity professionals and ethical hackers to intercept network authentication requests, capture NTLM hashes, and perform man-in-the-middle (MITM) attacks by mimicking legitimate servers. Developed by Laurent Gaffié, it targets Windows environments where LLMNR and NBT-NS are enabled by default, making it a powerful tool for credential harvesting and network security assessments.
