In addition to their free products, AT&T Cybersecurity offers a paid security platform, called Unified Security Management, that integrates threat detection, incident response, and compliance management into one application.[18] Threat applications are offered via hardware, virtual machines, and as a cloud service.[1]

The Open Threat Exchange (OTX), which is free, enables security experts to research and collaborate on new threats, better compare data and integrate threat information into their security systems.[13] A big data platform, OTX leverages natural language processing and machine learning.[13]

AT&T Cybersecurity also runs the Open Source Security Information Management (OSSIM) project, which helps network administrators with computer security, intrusion detection, and response.[19][20]


In August 2015, the firm raised $52 million to expand its security business. The round was led by Institutional Venture Partners and included GGV Capital, Kleiner Perkins, Trident Capital, and Jackson Square Ventures.[1][19]

The company said in 2015 that it was adding 300 to 400 new clients each quarter and it hired a Chief Financial Officer to help it prepare for a possible Initial Public Offering (IPO).[1]
