Case Study: a major insurance and financial services company strengthens Azure AD security with UnderDefense

Industry Leader secures Azure AD in under 30 min with UnderDefense

The client, a major insurance and financial services marketing firm, faced a significant security breach after threat actors used a phishing attack to compromise their CEO's Azure AD (now Entra ID) account. This unauthorized access led to a fraudulent invoice scheme. The client engaged UnderDefense for digital forensics and incident response (DFIR) services, as their existing security operations center (SOC) monitoring did not cover Microsoft 365 activity, leaving them vulnerable and unaware of the associated risks.

UnderDefense provided a comprehensive DFIR engagement to evict the attackers and remediate the breach. The vendor then implemented robust security improvements, including Azure AD Conditional Access policies and universal multi-factor authentication (MFA). By expanding the scope of SOC monitoring to include the Azure AD environment, UnderDefense helped the client achieve a formidable defense against unauthorized access, ensuring rapid detection and response to future threats.
