Juniper Networks announced today it has bought virtual security vendor Altor Networks for $95 million.

The acquisition builds on an existing relationship between the two companies, and Juniper actually invested in the company earlier this year. Founded in 2007, Altor specializes in intrusion prevention, firewall and monitoring for virtual environments.

With the purchase, Juniper seeks to deliver integrated, scalable security architecture protecting physical and virtual systems.

"Juniper is excited to acquire one of the industry’s leading virtualization security vendors and the extremely talented team that built it," said Mark Bauhaus, executive vice president and general manager of Service Layer Technologies at Juniper Networks, in a statement. "This acquisition will extend our leadership in data center and cloud security and will enable customers to deploy a consistent set of security services across their physical and virtual infrastructure, while delivering lowest total cost of ownership."

Forrester Research analyst Chenxi Wang noted that Altor has already integrated with Juniper that gives Juniper’s firewall visibility into traffic between virtual machines.
