How Palo Alto Networks Customers Are Protected

Palo Alto Networks customers are protected from attacks exploiting the Apache Log4j remote code execution (RCE) vulnerability. In addition, we offer a number of solutions to help identify affected applications and incident response if needed. Here’s how we help:
  • Blocking the Exploit: To give you time while your teams patch the vulnerabilities, Palo Alto Networks customers are protected by our Next-Generation Firewalls (PA-Series, VM-Series and CN-Series) or Prisma Access with a Threat Prevention security subscription, Cortex® XDR™ and Prisma® Cloud.
  • Incident Scoping: Palo Alto Networks can help provide this visibility using Prisma Cloud, Cortex XSOAR and Cortex Xpanse.
  • Incident Response: Our IR services can help companies of any size investigate and remediate potential threat actor activity.
