AlienVault CyberSecurity (now AT&T)

What AlienVault CyberSecurity (now AT&T) does

AlienVault was an independent cybersecurity company specializing in unified security management and threat intelligence, best known for its Open Threat Exchange (OTX) collaborative threat-intelligence platform. AlienVault was acquired by AT&T and now operates as part of AT&T's cybersecurity portfolio, with the AlienVault brand absorbed into the AT&T Cybersecurity product line; the legal entity holding the trademarks is AT&T Intellectual Property, and AT&T is a publicly traded company on the NYSE (ticker: T) headquartered in Dallas, USA.

AT&T's cybersecurity portfolio is a platform-plus-modules architecture centered on network-embedded security. The core products are AT&T Dynamic Defense, which detects and blocks malware, phishing, and ransomware in real-time at the AT&T network layer upstream of the customer firewall without requiring additional hardware; AT&T SASE, a managed convergence of SD-WAN and cloud-delivered security; and AT&T SD-WAN, which provides branch connectivity with embedded security and visibility. Add-on modules include AT&T ActiveArmor for internet connection security, AT&T Cybersecurity Consulting, and AT&T Business Continuity Planning. The portfolio also retains the legacy AlienVault brand, which is recognized as a major player in the Security Vulnerability Assessment Solutions Market alongside IBM, Microsoft, Qualys, Rapid7, McAfee, Hewlett Packard Enterprise, and NetIQ.

The business operates on a subscription revenue model, with cybersecurity services sold as managed subscriptions typically bundled with AT&T Dedicated Internet or Switched Ethernet on Demand connectivity, plus a professional services revenue stream from cybersecurity consulting. Go-to-market combines an enterprise field-sales motion (phone sales at 855.560.1206, Monday-Friday, 7 a.m.-7 p.m. CT) with a self-service online activation flow for SMB, a Business Center portal for mid-market account management, and a Partner Exchange program spanning VARs, Alliance Channel, and Go-to-Market Partners. Customers span enterprise and SMB across healthcare, sports entertainment, media and advertising (named logos include an Ohio hospital, the Dallas Cowboys, and Omnicom), with named use cases including an Ohio hospital incident in which Dynamic Defense blocked 228 million threat events within 24 hours and restored operations within minutes.
