Single incidents of intentional data exfiltration can have the greatest impact

Employees who intentionally exfiltrate data understand how to work around the policies and technical safeguards in place to steal valuable information or to inflict the most harm.

At the same time, organizations also suffer from non-malicious exfiltration from employees forwarding data and files to personal accounts to work on their own devices or print at home.

Traditional, static data loss prevention solutions, such as those provided by Microsoft 365 and secure email gateways (SEGs), are not intelligent enough to detect the subtle behavioral changes that people exhibit when exfiltrating data and prevent these incidents from occurring.
