If that is the case then JD Group can save huge bucks by replacing their Fortigates with Mikrotiks. No need to blow all your money on a 5% firewall condom like Fortinet.

Why spent 100% of your budget on 5% of the mitigation? I must use that in my next conversation with firewall admins...
My opinion is that this reasoning is flawed. In most cases admin configure DNS to the local ISP instead of Quad9. The local ISP when lead you to command and control faster than what you can say a Russian and slaptjips. They also probably have hundreds of stale rules and no documentation. Because not documenting what things do is a way to make you more safe so not only do the bad players not know what you doing but also yourself. Irrational, IMO. Then of course they are also using advanced traffic analytics because hacks usually occur with persistence. Weeks before the hack you'll see the Chinese receive the data.
Then of course they are most likely have the 5% condom configured using network attributes instead of identity. Even though they bought the identity license and everything else including the kitchen sink and SD-WAN.
And then the firewall is so good that you don't need micro segmentation and you can get to all your internal IoT devices including cameras and access control directly on the internal network which is just one zone. Because your only need three zones: internal, external and DMZ. The latter is best left empty according to best practice.
Cloud services are indeed not protected by a network firewall from a commercial vendor because they don't want to be hacked. They use Linux's netfilter. Most commercial firewalls are 10 year old forks of Linux or BSD and somehow we are meant to believe they can program the kernel better than the experts. Ja nee well fine.
Most companies with Fortigates push their websites through Cloudflare because inherently they know the their expensive tin sucks. Cloudflare is just Linux netfilter with a web UI that aggregates and orchestrates some sophisticated techniques. Here is a thought, maybe just use the cloud technology at the edge as well???
