OpenVAS, developed by Greenbone Networks, is a comprehensive open-source vulnerability scanner that detects security vulnerabilities across networks, hosts, web applications, and cloud environments using a vast library of Network Vulnerability Tests (NVTs). It supports authenticated and unauthenticated scans, compliance checks, and generates detailed reports via its web-based Greenbone Security Assistant (GSA) interface. As the community edition of the Greenbone Vulnerability Management framework, it provides enterprise-grade capabilities without licensing costs.

Burp Suite is an integrated platform for web application security testing, offering tools for manual and automated vulnerability assessment. It includes a proxy for intercepting traffic, an automated scanner for detecting common web vulnerabilities like XSS, SQLi, and CSRF, and utilities like Intruder and Repeater for manual exploitation. Developed by PortSwigger, it's widely used by penetration testers for comprehensive web app security evaluations.

Acunetix is an automated web vulnerability scanner that identifies critical security issues like SQL injection, XSS, CSRF, and OWASP Top 10 vulnerabilities in web applications, APIs, and complex JavaScript SPAs. It uses advanced crawling technology to handle modern web technologies including HTML5, single-page applications, and authentication mechanisms. The tool generates prioritized reports with proof-of-exploit evidence and integrates seamlessly with CI/CD pipelines, issue trackers, and other DevOps tools for efficient remediation.

Invicti is a leading dynamic application security testing (DAST) tool specializing in web vulnerability assessment, using proof-based scanning to detect and verify vulnerabilities like SQL injection, XSS, and more with minimal false positives. It scans websites, APIs, web services, and cloud environments, providing detailed reports and remediation advice. The platform integrates with CI/CD pipelines, ticketing systems, and collaboration tools to streamline secure development workflows.

OWASP ZAP (Zed Attack Proxy) is a free, open-source web application security scanner used for finding vulnerabilities in web applications. It functions as an intercepting proxy, allowing users to inspect, modify, and replay HTTP/HTTPS traffic while performing automated active and passive scans for issues like XSS, SQL injection, and CSRF. With support for scripting, API scanning, and a vast add-on marketplace, it's suitable for both automated assessments and manual penetration testing.

Nmap is a free, open-source network scanning tool renowned for host discovery, port scanning, service version detection, and OS fingerprinting. In vulnerability assessment, it shines through the Nmap Scripting Engine (NSE), which runs thousands of community-contributed scripts to detect vulnerabilities, misconfigurations, and gather exploit intelligence. While not a full-featured VA suite with automated reporting or patch management, it serves as a powerful reconnaissance foundation for manual and scripted assessments.

Nikto is an open-source, command-line web server scanner developed by CIRT.net that performs comprehensive tests against web servers for dangerous files, outdated versions, and misconfigurations. It checks for over 6700 potentially dangerous files/CGIs, version-specific problems on more than 1250 server types, and server issues on 270+ operating systems. While effective for quick web vulnerability assessments, it focuses primarily on server-side checks rather than deep application logic flaws.
