Does my device need to be online to work properly?

Hello i want to know if my device goes offline from your web admin if it still works in my intranet.For example my router has any kind of problem, etc…

Also about security, what can i say to my boss if he says that your operating system can sniff our network and passwords and expose us to bad things…

Regards

Your device will continue to work without a connection to our API, though it won’t be able to receive updates if communication is lost.
With regards to your question about security, I refer you to our security documentation, which can be found here https://www.balena.io/docs/learn/welcome/security/
