Key Things to Consider While Choosing Vulnerability Assessment Solution

Vulnerability assessment is vital to keep your data and assets secure from hackers. In this process, choosing the right vulnerability assessment software plays a crucial role in ensuring the quality, accuracy, and effectiveness of security testing. Hence, it is essential that you invest enough time to pick the right tool. The following are some tips from security experts on how to choose the best tool for vulnerability scanning.

Factors to Consider When Choosing Vulnerability Assessment Tool

Scanning Coverage

The vulnerability scanner you choose should be able to scan beyond the OWASP top ten and offer comprehensive coverage, including the CWE top 25. It should also scan web apps for more complex vulnerabilities like zero-day, business logic errors, out-of-band vulns, etc.

Automated Scans

Make sure that the scanning tool you choose offers automation to efficiently manage security testing, reduce manual efforts, and provide auto-generated remediation reports. This will save time and reduce the burden on your team, and they can test faster as well.

Scanning Depth

Avoid tools that offer surface-level scanning and cannot crawl protected resources. The best vulnerability assessment tools also offer credentialed scanning that can analyze protected web pages or resources with due authenticated access. It helps discover deeply hidden vulnerabilities.

Real-Time Alerts

The tool should offer instant alerts to your team as vulnerabilities are detected when integrated into the development workflow. Immediate alerts will enable your team to take prompt actions before a hacker can exploit the vulnerabilities, helping you strengthen web app security.

Scalability and Integration

Top vulnerability assessment tools are built to meet scalability needs as your infrastructure grows. They are capable of scanning applications, whether you scan one or hundreds. Additionally, it should be easily integrated with other security tools and in DevOps.

Actionable Reports

Make sure the vulnerability assessment tool offers actionable remediation reports with risk prioritization to help development teams promptly fix issues. Besides, the tool should also offer remediation steps and code fixes to remediate vulnerabilities faster.
