SET vs Responder vs Binary Ninja: Which Network Auditing Tool tool is Best in 2025?

SET, or Social-Engineer Toolkit, is a leading open-source framework pre-installed in Kali Linux (version 8.0.3), designed for ethical hackers and penetration testers. This social engineering toolkit for cybersecurity automates attacks like phishing, credential theft, and payload delivery, making it a premier penetration testing tool for social engineering assessments. With a 30.40 MB footprint and over 10 attack vectors, SET empowers red teams to simulate real-world threats, integrating seamlessly with Metasploit for robust security testing.

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.

Binary Ninja is a modern, open-source reverse engineering platform designed for disassembling, decompiling, and analyzing binary files across multiple architectures. Developed by Vector 35 Inc., a company founded by former CTF team members, Binary Ninja Free provides a downloadable, locally run tool for non-commercial use or evaluation, supporting limited architectures such as x86 and x86_64. Ideal for cybersecurity researchers, malware analysts, and students, it provides a clean GUI and robust analysis without requiring cloud uploads, unlike Binary Ninja Cloud.
