PRESS RELEASE

Cavium Networks (NASDAQ: CAVM), a leading provider of semiconductor products that enable intelligent processing for networking, communications, and the digital home, announced today that Palo Alto Networks, the network security company, intends to significantly increase its firewall performance by utilizing Cavium Networks OCTEON' II Processors for its next generation firewall product series. OCTEON II CN68XX incorporates 32 powerful 64-bit cores and unique hardware accelerators to enable industry-leading firewall application performance. Palo Alto Networks delivers next-generation firewalls that provide policy-based visibility and control over applications, users and threats.

Application visibility, application control and threat prevention is handled by three unique identification technologies from Palo Alto Networks: App-ID, User-ID, and Content-ID, to allow organizations to deploy next-generation firewalls and enable the secure use of new applications while managing the inherent risks. These fine-grained policy management and enforcement capabilities are delivered at low latency, multi-gigabit performance with the company's innovative Single Pass Parallel Processing (SP3) Architecture.

Palo Alto Networks has already massively deployed systems powered by OCTEON processors in its award-winning product lines, including the PA-4000 series. These next-generation firewall scans identify and filter traffic by user, instead of just by computer IP address and enable enterprises to create granular, business-relevant security policies and safely control applications, instead of the block-or-nothing approach offered by traditional port-blocking firewalls. Using Palo Alto Networks technology, enterprises can accurately identify and control applications by user, scan content to stop threats, and prevent data leakage -- all with a single network device. By reducing the number of security devices in their networks, companies can save both capital expenditures and operational costs.

"Palo Alto Networks is already delivering a new class of next-generation firewalls enabling the ability see and control applications, users and content -- not just ports, IP addresses and packets -- at up to 20 Gbps today," said Nir Zuk, founder and CTO of Palo Alto Networks. "We believe Cavium's OCTEON II processor family provides unmatched performance and best-in-class hardware acceleration needed to achieve Palo Alto Networks' market-leading performance and features."

OCTEON II processors provide the industry's broadest and highest performance multi-core MIPS64 processors with performance ranging from 1 Gbps to 40 Gbps in a single chip. The OCTEON processor family integrates 1 to 32 cores, networking interfaces and industry leading hardware acceleration for packet processing, quality of service, TCP offload, iSCSI offload, RAID, de-duplication Security, compression / decompression and deep packet inspection (DPI). OCTEON II processors are completely backward compatible with the existing range of OCTEON processors which enables a rapid and seamless customer transition to utilize Cavium's latest offerings.

About Palo Alto Networks Palo Alto Networks™ is the network security company. Its next-generation firewalls enable unprecedented visibility and granular policy control of applications and content -- by user, not just IP address -- at up to 20Gbps with no performance degradation. Based on patent-pending App-ID™ technology, Palo Alto Networks firewalls accurately identify and control applications -- regardless of port, protocol, evasive tactic or SSL encryption -- and scan content to stop threats and prevent data leakage. Enterprises can for the first time embrace Web 2.0 and maintain complete visibility and control, while significantly reducing total cost of ownership through device consolidation. Most recently, Palo Alto Networks has enabled enterprises to extend this same network security to remote users with the release of GlobalProtect™.
