Vulnerability Assessment is a continuous activity that should be performed regularly because vulnerabilities in an IT environment continuously change due to software updates, application changes, or emerging cyber threats. Companies hire pen testers or they use vulnerability management tools to find and fix security gaps before hackers do, making their security stronger.

FAQ's
When should you use open-source vulnerability management tools?
Small businesses that have a limited budget and a limited IT infrastructure, or your business doesn't need continuous or ongoing testing and only wants basic security by identifying common vulnerabilities. Free tools are also useful for learners such as security professionals, students, and organizations evaluating security before making larger investments. In these situations, free tools can be used.
When should you use commercial vulnerability management tools?
Businesses or security teams can use paid vulnerability management tools when you have a requirement for faster remediation, continuous monitoring of frequent changes, or your business manages plenty of assets, or your business complies with ISO 27001, PI DSS, HIPAA, DPDPA, or SOC 2. Or your IT infrastructure expands across various platforms such as cloud, endpoints, containers, and applications.
