A vulnerability scanner is a tool that scans computer systems, networks, or applications for vulnerabilities. A vulnerability is a weakness in a system that can be exploited by an attacker to gain access to the system or its data. Vulnerability scanners can help organizations identify and patch vulnerabilities before they can be exploited.
Vulnerability scanners are an important part of a comprehensive cybersecurity strategy. By identifying and patching vulnerabilities, organizations can reduce their risk of being hacked. Vulnerability scanners can also be used to track the effectiveness of security controls and to identify trends in vulnerability management.
