Cisco Systems Inc. (CSCO) said it bought Virtuata, a privately held security software firm, giving the highly acquisitive networking company new tools related to cloud computing and data center infrastructure.

Cisco is in the midst of a turnaround after restructuring last year to focus on core product areas such as routing and switching gear that shuttle data between computers. Cisco has said it is benefiting from telecommunications and other companies' need for more robust networks to support mobile and cloud computing.

The company said its newest deal "is well-aligned to our strategic goals to develop innovative virtualization, cloud and security technologies, while also cultivating top talent."

Financial details of the deal weren't disclosed. The Virtuata team, based in Milpitas, Calif., will join Cisco's Data Center Group.

Historically one of Silicon Valley's most active buyers, Cisco has focused more recently on acquiring start-ups and small companies.
