In addition to regular security audits and employee training, what other proactive measures can companies take to enhance their data security measures and protect sensitive customer information from potential breaches or cyber attacks?

A: Companies can implement multi-factor authentication for accessing sensitive data, regularly update and patch their software systems to address vulnerabilities, and encrypt all sensitive information both in transit and at rest. Additionally, companies can invest in advanced threat detection tools and monitoring systems to quickly identify and respond to any potential security breaches or cyber attacks.
