A powerful network scanner used to discover hosts and services on a computer network, building a map of the network topology. Freelancers use it for port scanning, service detection, and OS identification, which are critical first steps in any security assessment.
The world's foremost network protocol analyzer that lets you see what's happening on your network at a microscopic level. It is indispensable for troubleshooting, network monitoring, and analyzing packet data to detect anomalies or malicious activity in real-time.
A fast password cracker, currently available for many flavors of Unix, Windows, DOS, and OpenVMS. Freelancers use it to assess password strength and audit user accounts, helping clients identify weak credentials that need to be strengthened.
The world's fastest and most advanced password recovery utility, supporting over 350 highly optimized hashing algorithms. It is preferred by professionals for cracking complex passwords quickly, assisting in password auditing engagements with high efficiency.
An open-source web server scanner that performs comprehensive tests against web servers for multiple items, including over 6700 potentially dangerous files/programs. It helps freelancers identify outdated software, misconfigurations, and other security issues during web audits.
A free, open-source web application security scanner maintained by the OWASP foundation. It offers automated tools to find common vulnerabilities, making it an accessible starting point for freelance web security assessments without high licensing costs.
While not strictly hacking, this certification validates skills in securing network infrastructure, including firewalls and VPNs. Freelancers often need this background to understand the environment they are testing and to secure networks after remediation.
A vendor-neutral certification that validates the skills and knowledge required to plan and perform security assessments, and to identify and remediate vulnerabilities. It covers both network and application penetration testing, suitable for generalist freelance consultants.
A tool used to brute-force URIs, directories, and DNS hostnames in web applications and DNS domains. Freelancers use it to discover hidden paths and files on servers, which can often lead to sensitive information disclosure or unauthorized access.
An open-source penetration testing tool that automates the process of detecting and exploiting SQL injection flaws. It is a critical tool for freelancers conducting web application security tests, significantly reducing the time needed to identify database vulnerabilities.
A wordlist generator that creates all possible combinations of letters, numbers, and symbols based on user-defined patterns. Freelancers use it to create custom dictionaries for password cracking tools, optimizing attacks against specific client environments.
A complete suite of tools to assess WiFi network security, focusing on monitoring, attacking, testing, and cracking wireless networks. Freelancers specializing in wireless security use it to evaluate the strength of WPA/WPA2 handshakes and encryption keys.
An open-source penetration testing framework designed for social engineering. It helps freelancers simulate phishing attacks and understand human vulnerabilities, providing clients with insights into their employee susceptibility to cyber threats.
The industry-leading vulnerability scanner used by security professionals worldwide to detect vulnerabilities and compliance issues. Freelancers use it to perform comprehensive vulnerability assessments, generating detailed reports that guide remediation efforts for clients.
