To improve data security in your organization, start by regularly updating software and systems to fix security vulnerabilities. Train employees on safe data handling practices and use strong passwords. Encrypt sensitive data both in storage and during transmission. Implement access controls to limit who can view or modify data. Regularly back up data and store it securely. Consider hiring data security services for expert help and monitoring. Review and update security policies and procedures regularly to adapt to new threats. I refer you to MOATiT which provides the best data security services.
