What You Need to Know

Blocking all incoming network connections on your Mac prevents any unauthorized access or communication. However, it is important to note that this setting does not restrict outbound connections or prevent your Mac from sending its presence online if certain network features are enabled.

For example, if file sharing is enabled but all incoming connections are blocked, your Mac will still appear on network scans, but no one will be able to connect to it. To prevent your Mac from sending its presence online, simply disable the relevant sharing services in the settings.
