Hello,
Quick feedback : we use the Cloutik service for around 2 years for hotspots & LTE setups.
It’s running fine and we like the features which helped for remote diagnostic many times. Some glitches with the RouterOs v7beta on which we are doing some tests
We have full control on the devices, and we didn’t identify any security issue so far. Actually it helped us to have a better understanding on the devices activity & intrusion attempts.
The interface is functional but ergonomy is average compared to some other systems we are using.
If you are afraid of loosing control, just look at the scripts and follow the logs of your routers, because you still have full visibility of any action on your devices.
I understand that some people do not like (or trust) cloud management solutions like Cloutik, Unifi or Meraki, you can indeed build your own system in-house.
On our side, we didn’t have the time to do that & we preferred to focus on business.
Of course, there is a risk that the cost could increase in the future or that the service would end for any reason, but if they do that, we are still in charge of our devices and I’m sure some newcomers could take their place right away.
