In this world of technology, where cybersecurity has become an integral aspect of our lives, we can’t overlook the importance of real-time threat detection. New common IT vulnerabilities are discovered each year, with 2020 being the year to report the highest annual figure of vulnerabilities to date. A vulnerability is a security gap or loophole through which threat actors perform unauthorized actions by exploiting them.

Cybercriminals use different methods to exploit vulnerabilities, including buffer overflows, cross-site scripting (XSS), SQL injections, etc. While there are several ways to identify and patch loopholes in systems, vulnerability scanning tools play a significant role in detecting vulnerabilities

In this article, we will discuss what vulnerability scanning tools are, how they can help, and some of the best vulnerability scanning tools for businesses.

Disclaimer: The list presented here is not based on any rank criteria. Listed as First could not be the best or listed as Last in the list is not the worst by any means. This is not a complete product review. Please don’t go with the order of the tools. We clarify that the order doesn’t carry any rank. We are not here to judge the rank of the tools. We created this post to share the best options available in the market. Let’s get started.

What Are Vulnerability Scanning Tools?

Vulnerability Scanners use automated processes to conduct a scan on a computer or network to identify security gaps and points of exploitation. They examine Common Vulnerabilities and Exposures (CVEs), potential weaknesses, and security flaws in organizations’ systems, networks, and applications. Also, vulnerability scanners can produce detailed reports of security gaps to help businesses mitigate or remediate vulnerabilities.

Why Should You Use Vulnerability Scanners?

Attackers look for vulnerabilities in systems and applications to exploit them and attack businesses using different methods, including installation of malware, accessing the system’s memory, running code or modifying sensitive data.

Vulnerabilities can cause severe consequences for enterprises, leading to a data breach or ransomware attack. A vulnerability scanner can help resolve these issues by helping organizations identify security gaps in their environment. Benefits of vulnerability scanning tools include.

  • Identification of vulnerable versions of applications
  • Scanning and auditing internet-facing servers to identify network weaknesses
  • Visibility into the degree of threat from each vulnerability
  • Remediation and recommendation based on the nature of vulnerability to mitigate it
