AT&T CyberSecurity: Cybersecurity solutions provider offering threat intelligence, managed detection & response to mitigate cyber risks for enterprises.
Based in Dallas, Texas, AT&T Cybersecurity provides managed security services, advanced threat intelligence, and consulting to protect enterprise networks, endpoints, and data. The division operates on a business-to-business model, generating revenue through software-as-a-service subscriptions, managed security contracts, and professional consulting fees for corporate and government clients. Operating as a specialized unit, the organization leverages a global network infrastructure supported by AT&T, which generated approximately $122 billion in 2023 revenue and employs roughly 160,000 people worldwide. In late 2023, the corporate parent announced an agreement with WillJam Ventures to spin off the managed cybersecurity business into a standalone joint venture, which officially launched in 2024 under the new brand name LevelBlue. AT&T Cybersecurity was formally established in 2019 following the corporate acquisition of AlienVault, with former AlienVault executive Barmak Meftah serving as its initial president.

AT&T Cybersecurity is a division of AT&T focused on managed security services, providing tools and expertise to protect businesses from cyber threats through real-time detection, threat intelligence, and resilient solutions like zero-trust data security.[1][2][3] It serves enterprises, financial institutions, governments, and industries by addressing security gaps via products such as network security (e.g., Secure Web Gateway, SASE with partners like Palo Alto and Cisco), endpoint security, managed threat detection and response (MDR), and consulting services, solving problems like advanced threats, ransomware, and operational disruptions while enabling innovation.[1][3][5] Launched in 2019, it combines AlienVault acquisition, cybersecurity consulting, and managed services, demonstrating growth through integrations like AT&T Alien Labs for threat intelligence and partnerships with over 40 vendors.[1][3][4]
AT&T Cybersecurity launched in 2019 as a dedicated unit to consolidate and expand AT&T's security capabilities, integrating the acquired AlienVault platform—known for affordable, intelligent security tools like USM Anywhere—with in-house cybersecurity consulting and managed security services.[1][4] AlienVault, founded earlier with a mission to democratize world-class security for organizations of all sizes, brought expertise in threat detection and a passionate team focused on simplicity and affordability.[4] This move addressed "seams" in organizational security postures amid rising cybercrime, evolving from AT&T's broader network defense strategies that include multi-layered monitoring and rapid response.[1][2] Key early traction came from real-world deployments, such as leaner IT teams and enhanced data protection for clients like Keeley, leveraging centralized threat insights.[1]
AT&T Cybersecurity rides the wave of escalating cyber threats amid digital transformation, edge computing, and hybrid work, where rapid innovation amplifies attack surfaces like ransomware and supply chain risks.[1][5][7] Its timing aligns with regulatory pushes (e.g., CISA best practices) and market forces favoring managed services over in-house teams, especially for SMBs and sectors like finance and government facing skills shortages.[3][5][8] By embedding security at the network level and providing upstream defense, it influences the ecosystem through empirical insights reports, public education, and partnerships that standardize resilient practices, helping industries maintain continuity while accelerating cloud and 5G adoption.[2][6][7]
AT&T Cybersecurity is poised to expand its MDR and SASE offerings, integrating AI-driven threat intelligence from Alien Labs to counter evolving edge and zero-trust demands.[1][3][7] Trends like real-time predictive analytics and regulatory scrutiny will shape its growth, potentially amplifying influence via deeper government collaborations and global insights reports.[2][8] As cybercrime intensifies, its network-native model positions it to lead in proactive defense, tying back to its core mission of safer innovation for businesses worldwide.[1][5]
AT&T CyberSecurity has raised $117.0M across 6 funding rounds. Most recently, it raised $52.0M Series E in August 2015.
