Hello j1udith,

I found this solution. Can you tell us if it helps, please?

The Virus Outbreak Protection Service (VOS) in FortiGate is designed to enhance antivirus protection by using malware hash signatures from FortiGuard’s Global Threat Intelligence servers. Here's a breakdown of your queries:

1. Real-world Blocking: The VOS can block files deemed malicious by matching their hash against FortiGuard's database. This real-time detection helps in identifying zero-day threats before traditional signatures are available.
   
   

2. File-based Protection: Yes, VOS is primarily file-based as it is part of the antivirus profile. It focuses on identifying malicious files through hash signature matching.
   
   

3. Comparison with Palo Alto Networks:

   • Palo Alto Networks' WildFire is indeed more focused on sandboxing, where files are executed in a virtual environment to observe their behavior. It also uses crowdsourcing, where once a file is identified as malicious, the information is shared across all customers.
   • While both services aim to enhance threat detection, VOS relies on hash matching, whereas WildFire uses behavioral analysis in a sandbox environment.

Both services provide additional layers of security, but they operate using different methodologies.
