Nessus is a leading vulnerability assessment tool developed by Tenable, Inc., widely recognized as the industry’s most trusted scanner for identifying security weaknesses across networks, devices, applications, and cloud environments. Launched in 1998 as an open-source project by Renaud Deraison, it transitioned to a proprietary model in 2005 and now offers two enterprise versions: Nessus Professional and Nessus Expert. With over 252,000 plugins and 100,000 plus CVEs, Nessus delivers high-accuracy scans to detect vulnerabilities, misconfigurations, and compliance issues. It supports unlimited IT assessments, customizable templates (450+), and vulnerability prioritization using CVSS v4, EPSS, and Tenable’s VPR. Nessus Expert extends capabilities to web application scanning, external attack surface monitoring, and cloud infrastructure audits.

Lynis, developed by CISOfy, is an open-source security auditing and hardening tool for Linux and Unix-based systems included in Kali Linux. It performs comprehensive system scans to identify vulnerabilities, misconfigurations, and compliance issues, generating detailed reports for professional auditors and system administrators. Lynis supports automated audits, forensic analysis, and penetration testing modes, offering over 300 tests for file permissions, software updates, and network security. It integrates with compliance frameworks like PCI DSS and HIPAA.

DMitry is a command-line utility included in Kali Linux for passive information gathering during penetration testing and ethical hacking. Written in C, it collects public data about a target host, including subdomains, email addresses, uptime information, open TCP ports, and whois details for domains and IP addresses. DMitry also retrieves Netcraft data, such as operating system and web server details. Its lightweight design, with a 50 KB installed size, makes it ideal for quick reconnaissance, reducing the need for multiple tools. Key features include customizable TCP port scanning with TTL settings, filtered port reporting, and banner grabbing.
