Case Study: Altice Portugal strengthens Active Directory resilience with Semperis

Altice Portugal secures 20,000 Active Directory accounts with Semperis

Altice Portugal, a leading telecommunications operator, faced significant challenges securing its large and complex Active Directory environment, which was the result of multiple mergers and acquisitions. This complexity created security gaps and made it difficult to detect identity-based threats, leaving the company highly concerned about catastrophic ransomware attacks. To address these issues, Altice Portugal partnered with vendor Semperis to strengthen its identity threat detection and response (ITDR) strategy.

Semperis implemented its Directory Services Protector (DSP) and Active Directory Forest Recovery (ADFR) solutions. The DSP tool simplified the detection of anomalous behavior and misconfigurations by integrating with the security operations center, while the ADFR module guaranteed a segregated and rapid recovery process. This solution provided Altice Portugal with enhanced threat visibility, streamlined operations for its technical team, and the ability to recover its critical Active Directory infrastructure in a matter of hours, significantly improving its cyber resiliency.
