Security scanners are tools used to identify vulnerabilities in computer systems and networks. They work by examining software, hardware, and configurations to find weaknesses that could be exploited by cybercriminals. By regularly using security scanners, organizations can protect their sensitive data and maintain the integrity of their systems. There are different types of security scanners, including network scanners, web application scanners, and vulnerability scanners. Each type focuses on specific areas, helping businesses ensure that their firewalls, servers, and applications are secure. Regular scanning is essential for staying ahead of potential threats and safeguarding valuable information.
