Deep dives

The Growing Need for Multi-Factor Authentication (MFA)

The adoption of multi-factor authentication (MFA) has surged over the past five to ten years, becoming an essential security measure for organizations. It enables an extra layer of security beyond just a username and password, especially in light of recent security vulnerabilities. Despite its wide application across businesses, there are still notable exceptions, such as in law firms and healthcare institutions, which often lag behind in implementing MFA due to operational challenges and legacy systems. The importance of MFA has escalated alongside concepts like zero trust in security frameworks, reinforcing the need for this protection across all digital footprints.
