Enhanced Cybersecurity Service to help you defend against advanced persistent threats

AT&T Enhanced Cybersecurity Service

AT&T is one of the few qualified providers to offer an enhanced cybersecurity service that utilizes classified cyber threat indicators supplied by the Department of Homeland Security to help defend companies against advanced persistent threat attacks. This service offers Malicious Email Filtering (MEF) and Domain Name System (DNS) sinkhole security, both of which help to provide protection that goes beyond the email and DNS filtering services commonly utilized today. It also employs custom algorithms, malware signatures, and countermeasures to help detect and address data exploitation.
