Sorry for my ignorance, but I can’t seem to find a technical explanation of how a cloud service could possibly replace a hardware firewall. Everything I’ve found is just useless marketing fluff.
Can anyone ELI5 how FWaaS is able to work without intimate cooperation from every ISP or a local hardware installation? Thanks in advance!
They’re usually local hardware but configured and managed via cloud services. Although I’ve seen people using EC2 instances as firewalls for some cursed enterprise reasons, which I guess does make it a firewall in the cloud.
I mean a lot of the services that companies are using are cloud-hosted, meaning that especially if you have branch offices or a lot of remote workers a normal firewall in the datacenter introduces an unnecessary bottleneck. Putting the logical edge of your organization’s network in the cloud too makes sense from a performance perspective in that case, and then turning the actual firewalls into SaaS seems much less absurd.
