The SEM solution uses a modular, standards-based web services architecture designed to ensure portability and reliability. The SEM Server’s core functions are mobile device and virus update management, and reporting and tracking. These functions are implemented using industry standards including XML, SOAP, SSL, LDAP, and Java. The SEM Server can reside on a single dedicated hardware server, and as organizations grow, the core functions can be distributed across multiple child servers, resulting in a highly scalable, flexible and well-balanced solution that addresses a wide range of configuration requirements and preferences.
