Calabasas-based network testing software and hardware provider Ixia is applying its technology into a new area--cyber attack detection and incident response--via a partnership with Plixer International, the company said yesterday. According to Ixia and Plixer, they have integrated their systems as part of a cyber threat incident response solution. The two said the joint solution helps improve forensic incident response and application optimization, to help prepare for cyber attack and application performance issues. Financial details of the deal were not disclosed. The new solution is built on Ixia's ATI Processor, which peforms network packet processing and packet inspection, and sends that to Plixer's threat management and detection software.
