Automated compliance monitoring tools provide a continuous and objective means of enforcing and verifying compliance with security policies and regulations. They can offer real-time alerts and reports, thus enabling the security team to act swiftly on non-compliant issues. While all options could play a role in compliance monitoring, automated tools are specifically designed to provide ongoing assurance of compliance and therefore are the best choice for continuous monitoring. Manual compliance checks, though important, are more intermittent and subject to human error. Training enhances the awareness of compliance requirements but does not monitor compliance itself. Feedback loops aid in adjusting policies but do not conduct the actual monitoring.
