Factors to Look for in Vulnerability Testing Tools

Schedule Automated Scans
Look for a vulnerability assessment tool that allows you to schedule regular and ad hoc scans of various depths and durations by leveraging a comprehensive vulnerability database (regularly updated with the latest threats).
Prioritize Critical CVEs and Risk Assessment
Choose an assessment tool that prioritizes vulnerabilities based on severity, exploitability, and the criticality of the affected asset to help your security team focus on the most pressing issues first.
Scan Behind Login
Prioritize tools that utilize login credentials to enable testing for vulnerabilities, such as session hijacks, SQL injection, and IDOR, that aren’t detectable from outside the network perimeter, providing a more thorough security assessment.
Leverage Real-Time Alerts
Look for a scanner that goes beyond continuous monitoring to provide real-time alerts via email or SMS or flag issues on SIEM platforms whenever a critical vulnerability is identified to ensure timely notification and resolution.
Report Vulnerabilities and Ensure Compliance
Choose assessment tools that generate detailed reports, including information such as the severity of the vulnerability, the affected system, re-creation, and recommended remediation steps.
Integrate with CI/CD Pipeline
Focus on vulnerability assessment software that integrates seamlessly with your existing tech stack, such as ticketing systems, SIEM systems, and patch management tools, including GitHub, GitLab, Slack, and JIRA, for a more streamlined workflow.

FAQs
What are the five types of vulnerability assessment?
Five types of vulnerability assessments can scan for weaknesses in your systems: network-based for wired and wireless networks, host-based for individual devices, wireless specifically for Wi-Fi security, application-based to find flaws in software, and database-focused to identify risks in data storage.
What is CVE check tool?
A CVE check tool is an automated program that searches for weaknesses in computer systems and applications, like missing security patches or misconfiguration by comparing it to a database of known CVEs.
What are vulnerability assessment tools?
Vulnerability assessment is the process of detecting the vulnerabilities extant in your systems, analyzing them, and finding out ways to fix them using automated tools to scan your systems for vulnerabilities and categorize them according to their severity.
What are the three types of vulnerability assessments?
There are three main types of vulnerability assessments: external, internal, and asset-specific. External assessments evaluate vulnerabilities from outside the network, while internal assessments focus on vulnerabilities within the network. Asset-specific assessments analyze specific assets or systems for vulnerabilities.
