What is Palo Alto PAN-DB?
Palo Alto Networks PAN-DB is the URL filtering database powering next-generation firewalls (NGFW) deployed across Fortune 500 companies, government agencies, and enterprises worldwide. PAN-DB categorizes billions of URLs into 80+ categories, and firewalls use these categories to allow or block traffic. When your domain is categorized as "Malware," "Phishing," or "Command-and-Control," Palo Alto firewalls hard-block all employee access, with no user bypass option.
Why Palo Alto PAN-DB flags legitimate domains
- PAN-DB automated crawlers detected malicious patterns or exploit code on your website
- Your domain was associated with command-and-control traffic in Palo Alto threat intelligence
- Behavioral heuristics flagged suspicious redirect chains, obfuscated JavaScript, or drive-by download patterns
- Your hosting IP or subnet has historical threat activity in Palo Alto Unit 42 research
- Third-party scripts or ad networks on your site triggered PAN-DB's malware classification
- A past compromise was detected and the malicious categorization was never updated after cleanup
What a listing means for your business
A PAN-DB malicious categorization means your website is hard-blocked on every Palo Alto firewall globally, affecting Fortune 500 companies, government agencies, hospitals, and universities. Users see a block page with no option to proceed. This is an enterprise-grade firewall block, not a browser warning users can click past.

Frequently asked questions
How do I check my PAN-DB categorization?
Visit urlfiltering.paloaltonetworks.com and enter your domain. It shows the current category (e.g., Malware, Phishing, Business) without needing an account. Reclassification requests now require a free account.
Can enterprise admins bypass PAN-DB blocks for my site?
Firewall administrators can create custom URL category overrides to temporarily allow your domain while you pursue official reclassification. Suggest this to affected enterprise customers as a workaround.
