Ubiquiti EdgeRouter X ER-X and privacy?

Has anyone used this product? Is it a good option to ensure some firewall rules and blocking and vlan segmentation?

I am a bit worried that this device offers too many options, and somehow someone might be able to access its servers from the outside. I mean I ’m not sure if it’s too complex to be able to setup properly without exposing some weakness of its OS to a possible hacker.

On the other hand it looks like a good router+switch+firewall combination.

Also, does this manufacturer have a good reputation concerning safety and privacy?
