The frequency of vulnerability assessments depends on your organization’s size, industry, and security needs. However, it is generally recommended to conduct assessments at least quarterly. Additionally, you should perform an assessment after significant changes to your IT environment, such as system upgrades, new software deployments, or network expansions. Regular assessments help maintain a strong security posture, reduce risks, and ensure compliance with regulations. For high-risk industries like finance or healthcare, more frequent assessments may be necessary to stay ahead of evolving threats and ensure critical data protection.
