announced Tuesday that it will acquire a Silicon Valley cybersecurity startup as part of its efforts to offer security software to small- and medium-size businesses. The companies did not disclose terms of the deal for AlienVault, which has raised $116.4 million in venture capital, according to FactSet. AT&T said the purchase would not have a material effect on its results, nor affect its plan to reduce its debt-to-profit ratio. “AlienVault’s expertise in threat intelligence will improve our ability to help organizations detect and respond to cybersecurity attacks,” AT&T’s chief executive for the AT&T Business unit, Thaddeus Arroyo, said in Tuesday’s announcement. AlienVault was backed by venture investors including Kleiner Perkins Caufield & Byers and Intel Corp.’s
Intel Capital. AT&T shares were trading about 0.2% higher in Tuesday trading, and have decreased 17.1% so far this year, as the S&P 500 index
has gained 4.1%.
