Company Description

AT&T is one of the most famous names in the enterprise market, dating back to the early days of the telegraph and the telephone. It has been reborn as a global telecommunications and IT services provider, offering security device management and monitoring services for large enterprises, midsize businesses and governments. Its headquarters are in Dallas, and it has regional offices in London and Hong Kong. It has five 24/7 security operations centers (SOCs) —  one in Europe, one in Asia/Pacific, and three in the U.S — and three business-hour SOCs.

Analyst View

Gartner said AT&T would be a good fit for organizations with a preference for services to be sourced from a single supplier, particularly managed network services and IT infrastructure security controls. Its security portfolio complements its managed network infrastructure and service offerings. It is positioned as a Challenger by Gartner. However, it lacks support for Microsoft Azure and has limited support for software as a service (SaaS) providers (Office 365, Box and Salesforce are supported).
