AT&T announced Tuesday its plans to acquire AlienVault, a privately held company, to enable it expand its enterprise-grade security solutions to small and medium-sized businesses.

AlienVault is based in San Mateo, Calif.

The agreement will combine AlienVault’s expertise in threat intelligence with AT&T’s cybersecurity solutions portfolio that includes threat detection and prevention as well as response technologies and services.

“Regardless of size or industry, businesses today need cyber threat detection and response technologies and services,” said Thaddeus Arroyo, CEO, AT&T Business. “The current threat landscape has shifted this from a luxury for some, to a requirement for all.”

“AlienVault’s expertise in threat intelligence will improve our ability to help organizations detect and respond to cybersecurity attacks.”

Terms of the deal were not disclosed, but the transaction is expected to close in the third quarter of 2018.
