Palo Alto Networks Enterprise Firewall PA-820

Model: PA-820

  • Identifies the application, regardless of port, encryption (SSL or SSH), or evasive technique employed
  • Uses the application, not the port, as the basis for all of your safe enablement policy decisions: allow, deny,


Classifies all applications, on all ports, all the time

  • Identifies the application, regardless of port, encryption (SSL or SSH), or evasive technique employed
  • Uses the application, not the port, as the basis for all of your safe enablement policy decisions: allow, deny, schedule, inspect and apply traffic-shaping
  • Categorizes unidentified applications for policy control, threat forensics or App-ID™ application identification technology development

Enforces security policies for any user, at any location

  • Deploys consistent policies to local and remote users running on the Windows®, Mac® OS X®, Linux®, Android™ or Apple® iOS platforms
  • Enables agentless integration with Microsoft® Active Directory® and Terminal Services, LDAP, Novell® eDirectory™ and Citrix®
  • Easily integrates your firewall policies with 802.1X wireless, proxies, NAC solutions, and any other source of user identity information

Prevents known and unknown threats

  • Blocks a range of known threats, including exploits, malware and spyware, across all ports, regardless of common threat-evasion tactics employed
  • Limits the unauthorized transfer of files and sensitive data, and safely enables non-work-related web surfing
  • Identifies unknown malware, analyzes it based on hundreds of malicious behaviors, and then automatically creates and delivers protection

Palo Alto Networks PA-800 Series next-generation firewall appliances, comprised of the PA-820 and PA-850, are designed to secure enterprise branch offices and midsized businesses.

The controlling element of the Palo Alto Networks® PA-800 Series appliances is PAN-OS® security operat- ing system, which natively classifies all traffic, inclusive of applications, threats and content, and then ties that traffic to the user, regardless of location or device type. The application, content and user – in other words, the business elements that run your business – are then used as the basis of your security policies, resulting in an improved security posture and a reduction in incident response time.
