CIS Security's challenge
CIS Security struggled with maintaining email branding consistency across their extensive workforce. Employees sent approximately 14,500 emails daily, but inconsistent email signatures posed both a security risk and a missed marketing opportunity.
The manual process of managing signatures for 2,900 employees across various devices was inefficient, vulnerable, and time-consuming.
