Vulnerability checks require appropriate Nmap Scripting Engine scripts, and Nmap is not a complete vulnerability-management platform. Nmap is suitable for network discovery and service enumeration, but beginners needing prioritized findings and remediation guidance should use a dedicated vulnerability scanner.

7: OpenSCAP

OpenSCAP is a set of tools that helps in security measure creation, vulnerability assessment, and scanning for vulnerabilities. OpenSCAP is a resource created by communities that is free and open-source. OpenSCAP primarily evaluates Linux and other Unix-like systems using SCAP security policies, supported platforms depend on the scanner package and available security content.

OpenSCAP focuses on system configuration, compliance, inventory, and known-vulnerability evaluation through SCAP content. It is not a general-purpose web application, database, or network vulnerability scanner. Additionally, they offer a facility for risk assessment and assistance in finding threats.

8: GoLismero

A free and open-source vulnerability scanning tool is called GoLismero. GoLismero concentrates on identifying web application vulnerabilities, but it can also search for weaknesses in the network. 

Database and network vulnerabilities are among the many vulnerabilities that GoLismero covers. GoLismero aggregates and correlates security-tool results but does not implement or enforce remediation countermeasures.

9: Intruder

Intruder is a commercial vulnerability-management platform for external and internal infrastructure, cloud environments, web applications, and APIs, it is not limited to cloud storage. Intruder performs scheduled and continuous exposure monitoring and can trigger checks when significant new vulnerabilities are identified. Intruder’s automated scanning system continuously checks for vulnerabilities.

Due to its capacity to control numerous devices, Intruder is appropriate for enterprise level vulnerability scanning.

10: Aircrack

Aircrack-ng is a Wi-Fi security auditing suite for monitoring, packet capture, adapter testing, replay attacks, deauthentication testing, and WEP/WPA-PSK key testing. Aircrack-ng can attempt to recover WEP and WPA/WPA2-PSK keys from authorized captures; it cannot recover arbitrary lost Wi-Fi keys.
