What is virtual firewalls?

Virtual firewalls are software-based firewalls that provide the same security functions as hardware firewalls but operate in virtualized environments. They are used to protect virtual machines, virtual networks, and cloud environments by inspecting network traffic and enforcing security policies. They can be deployed on hypervisors or in the cloud, offering scalability and flexibility for securing dynamic virtualized infrastructures. They are used to segment networks, control traffic between virtual machines, and protect against threats from both inside and outside the virtual environment.
