How we are different

● As the largest SD-WAN Managed Service Provider in North America, AT&T has a holistic understanding of what businesses need as they modernize and transform their networks, including the importance of security being a critical component of any business initiative. In addition to the people, process, and technology that are delivered through AT&T Managed Security Services spanning eight global SOCs, AT&T Cybersecurity delivers accountability with thorough communication and comprehensive reporting to clients along with coordinated responses with defined service level agreements on change requests.

● During the pandemic, AT&T Cybersecurity has helped customers persevere through the various disruptions caused by COVID-19 with its managed security services. Additionally, to maintain business continuity, AT&T Cybersecurity supported customers of its AT&T DDoS Defense service as well as non-subscribing customers with emergency mitigation services. In these instances, AT&T redirected the network of affected organizations to its scrubbing centers to block the malicious traffic, while letting legitimate transactions flow unimpeded, allowing business to resume without paying these inflated ransom demands.
● As one of the largest MSSPs in the world, AT&T Cybersecurity fosters strong relationships with leading security technology providers while incubating emerging innovators to provide best-in-class services. In 2021, AT&T was first to market with a global, managed SASE solution at scale. AT&T utilized strategic relationships with Fortinet, Palo Alto Networks and Cisco to expand its portfolio of managed security services, offering new SASE solutions and providing a choice for customers of technologies to best meet their converged network and security needs. AT&T also worked closely with SentinelOne to launch a Managed Endpoint Security solution to address increasing endpoint security threats.
