Software-based WAFs are suitable for small and medium-sized organizations.ģ. It is not as fast as a hardware-based WAF, since a higher latency is experienced during the monitoring and filtering process. It can be used within an on-premises system, and can also be deployed in the cloud, connecting to cloud-based web and application servers. The biggest benefit of a software-based WAF is its flexibility. The one difference is that users would need to have their own hypervisor to run the virtual machine. All the WAF components are essentially the same as a hardware WAF. Software-based WAF: Different from a hardware-based WAF, a software-based WAF is installed in a virtual machine instead of a physical hardware appliance. They are most suitable for large businesses.Ģ. Due to their physical proximity to the server, they track and filter data packets to and from the website with very low latency. Hardware-based WAFs have fast speed and high performance.
Hardware-based WAF: A hardware-based WAF is deployed through a hardware appliance, installed within the LAN close to the web and application servers.
