Maltego vs Yersinia vs Responder: Which Linux Security Auditor tool is Best in 2025?

Maltego is an all-in-one cyber investigation platform developed by Maltego Technologies GmbH, headquartered in Munich, Germany, designed to accelerate open-source intelligence (OSINT) and complex cyber investigations. It enables users to mine, merge, and map data from over 120 data partners, including social media, dark web, and breach databases, visualizing connections through its flagship Maltego Graph tool. The platform supports novice analysts with Maltego Search for quick OSINT queries, technical investigators with Maltego Graph for deep link analysis, and public safety teams with Maltego Monitor and Maltego Evidence for real-time social media monitoring and evidence collection. Trusted by over 200,000 users, including the FBI, INTERPOL, and 60% of Dow 30 companies, Maltego is ISO 27001:2022 certified and GDPR-compliant, offering secure, cost-efficient access to data with customizable integrations.

Yersinia is an open-source, robust framework for executing layer 2 (Data Link Layer) network attacks, designed to exploit vulnerabilities in various network protocols. Integrated into Kali Linux, Yersinia empowers cybersecurity professionals, penetration testers, and network administrators to analyze and test the security of deployed networks. Named after the plague-causing bacterium Yersinia pestis, it targets protocols like STP, DHCP, CDP, and VLAN, enabling users to simulate attacks such as DHCP starvation, VLAN hopping, and spanning tree manipulation.

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.
