Enterprises are constantly challenged to protect their data and assets from malicious attacks requiring many efforts to identify and address vulnerabilities. According to research conducted in 2022, 70% of businesses worldwide fell victim to a Ransomware attack, and only 38% of global organizations claim they are prepared to handle a sophisticated cyber-attack. This blog will explore the best among the top vulnerability scanners enterprises should consider for security.

However, vulnerability scanners have emerged as essential tools for enterprises seeking to protect their IT assets since cybercriminals can breach vulnerabilities within a company’s IT infrastructure if those weaknesses go unnoticed. Since a vulnerability scanner forms the base of your vulnerability management solution, you must be smart while evaluating and selecting the best scanner.

How to Choose a Vulnerability Scanner?

Choosing a suitable vulnerability scanner is essential to effectively identify and remediate security risks in your organization’s systems and applications. You will heavily rely on the selected scanner to help prevent daily attacks. So how do you know if the scanner you chose is effective?

Here are some tips for choosing the best vulnerability scanner,

This is because many organizations have a mix of assets with different operating systems and many third-party applications. Also, check if the vendor has strict service level agreements covering new vulnerabilities, including zero days.
  2. Accuracy: The higher the accuracy, the higher the advantage of getting results. Effective scanners provide mechanisms to reduce false positives. The accuracy of vulnerability scanners directly impacts an organization’s ability to identify and mitigate security risks effectively.
  3. Scanning Frequency and Speed: Consider how often you need to perform scans and how quickly the scanner can complete a scan. For any Organization, having a rapid vulnerability scanning tool is a huge advantage and will reduce downtime. If your vulnerability scanner takes much bandwidth during scans, you will have to compromise on the productivity of your systems and users.

Ensure you obtain clear and insightful reports, which give you an understanding of your risks and take action to mitigate them.
  5. Integrated Remediation: Showing the vulnerabilities is not enough if the scanner doesn’t provide a remediation solution. Ensure the selected scanner has integrated remediation and provides a solution for every vulnerability detected.
  6. Ease of Use: A scanner with a simplified, user-friendly interface simplifies identifying vulnerabilities, enabling security teams to navigate the scanning process and interpret the results effectively and quickly.
  7. Integration with Other Applications: Vulnerability scanner
    inspects vulnerabilities in software and systems, it needs to be flexible in integrating with other tools and technologies used by enterprise users.
