How do virtual firewalls differ from traditional hardware firewalls?

Virtual firewalls function differently from traditional hardware firewalls in modern networks due to their deployment method. Virtual firewalls are software-based firewalls that run on virtual machines or cloud instances, whereas traditional hardware firewalls are physical devices. Virtual firewalls provide flexibility, scalability, and cost-effectiveness as they can be easily deployed and managed in virtualized environments or the cloud. They can dynamically adjust to changing network conditions and workload demands. On the other hand, traditional hardware firewalls are static in nature and are limited by the capacity of the physical appliance.
