Before you start looking for data security certifications, you need to have a clear idea of what kind of data security role you want to pursue. Data security is a broad field that covers different domains, such as network security, cloud security, application security, cryptography, risk management, compliance, and more. Depending on your interests, experience, and education, you may want to specialize in one or more of these areas, or aim for a generalist or managerial position. You should also consider your current and desired level of responsibility, as some certifications are more suitable for entry-level, intermediate, or advanced roles.
