AT&T plans to purchase privately-held cybersecurity company AlienVault to bolster its security solutions portfolio for small and medium-sized businesses, the telecom giant announced Tuesday.

The deal is expected to close in the third quarter of 2018, but financial terms were not disclosed.

San Mateo, Calif.-based AlienVault offers tools to identify and respond to cyber security threats via its Unified Security Management platform. The company also operates the Open Threat Exchange (OTX), which is an open online community platform where researchers and security professionals can communicate data and information on threat intelligence.

“AlienVault’s expertise in threat intelligence will improve our ability to help organizations detect and respond to cybersecurity attacks. Together, with our enterprise-grade detection, response and remediation capabilities, we’re providing scalable, intelligent, affordable security for business customers of all sizes,” Thaddeus Arroyo, CEO at AT&T Business, said in a statement.

AT&T said it will continue to invest in and build on AlienVault’s USM platform and OTX forum as the company is integrated into AT&T’s cybersecurity services. Until the deal closes each company will continue to operate independently. After that, AlienVault will become part of AT&T’s Edge-to-Edge Intelligence capabilities, which span from the core of a company’s network to all endpoints.

AlienVault has raised about $120 million since it was founded in 2007, according to VentureBeat.  Investors include Intel Capital, Trident Capital, Jackson Square Ventures and GGV Capital.

AlienVault counts Foot Locker, SoulCycle, Subaru, and Domino’s among its more than 7,000 customers, according to the company website.
