Security Capabilities: The safety functions you require will also affect the VM capacity you want. For example, if you need sophisticated threat prevention, you may need a bigger VM capacity to handle the increased system requirements.
Data Volume: The amount of data your FortiGate VM needs to process is a crucial factor in identifying the correct VM size. Consider the count of clients, programs, and services that will be defended by your FortiGate VM.
Networking Throughput: The network throughput necessary by your FortiGate VM is another important aspect. Evaluate the volume of information that needs to be handled and the needed connection bandwidth.
