Security Solution
Directory Services Protector (DSP)
The industry’s most comprehensive identity threat and response (ITDR) platform for Active Directory and Azure AD
Business applications on-premises and in the cloud rely on Active Directory and Azure Active Directory, making it a critical piece of your IT infrastructure. But securing Active Directory is difficult given its constant flux, its sheer number of settings, and the increasingly sophisticated threat landscape. Protecting a hybrid system brings additional challenges, as many attacks start on premises and move to the cloud. Semperis Directory Services Protector (DSP) continuously monitors AD and Azure AD for indicators of exposure and provides a single view of activities, both on-premises and in the cloud.

Active Directory Forest Recovery (ADFR)
Cyber-first disaster recovery for Active Directory

Semperis orchestrates a fully automated forest recovery process—avoiding human errors, reducing downtime from days and weeks to minutes, and eliminating the risk of malware reinfection.
