Palo Alto Networks
Santa Clara, Calif.-based Palo Alto Networks has been seen by industry analysts as an innovative next-generation firewall (NGFW) vendor. The firm touts secure application enablement to control application-function usage across the corporate network. Its WildFire service uses a cloud-based sandbox to test suspicious files and monitor behavior in an attempt to identify new malware. The company competes in a market that has been consolidating. Sourcefire was acquired by Cisco Systems, and McAfee recently acquired Stonesoft. Both firms were seen as innovators in the NGFW market.
