Why did AT&T buy AlienVault?
AT&T wanted to combine AlienVault’s threat intelligence and detection technology with its own security portfolio. AT&T described the deal as a way to connect threat detection, prevention, response, remediation, managed-security services, and network visibility.
The strategy also addressed a customer-size gap. AT&T said the combined offering could bring enterprise-grade security capabilities to millions of small and medium-sized businesses, not only to large enterprises that traditionally purchased extensive security services.
What did AT&T get from AlienVault?
Unified Security Management
AlienVault’s Unified Security Management platform provided threat detection and incident-response capabilities, along with compliance features described in AT&T’s acquisition announcements. USM was intended to consolidate security monitoring and response functions rather than require customers to assemble every capability separately.

How much did AT&T pay for AlienVault?
The purchase price was not disclosed by AT&T or AlienVault. AT&T said the transaction was not expected to have a material effect on its financial results. For background, CyberScoop reported that AlienVault had raised about $118 million in venture funding, citing Crunchbase data from 2018; that funding total is not the acquisition price.

After the August 22, 2018 closing, Barmak Meftah became president of a standalone AT&T cybersecurity solutions division while continuing as CEO of AlienVault. Meftah said the combination could simplify cybersecurity and automate how customers addressed their security needs.
