Palo Alto Networks is a network security company founded in 2005 that provides next-generation firewalls and cloud-based malware analysis. It has over 1,000 employees globally and 11,000 enterprise customers. Palo Alto Networks firewalls can identify applications, users, and threats within network traffic through its single-pass parallel processing architecture. This allows fine-grained security policies to be applied based on applications rather than just ports. The company also operates a cloud-based malware analysis service called WildFire that automatically analyzes suspicious files and shares threat intelligence with customer firewalls.
