FAQs
Is Netiquette free?
Yes. Netiquette is one of the free tools published by Objective See, a foundation that builds open source Mac security software supported by its community.
Does Netiquette block connections?
No. Netiquette is a monitor, so it shows and explains network activity rather than stopping it. Blocking traffic is the job of a firewall app.
Can I use Netiquette from the terminal?
Yes. The app includes a command line mode that lists all active connections as JSON, which is handy for scripts and quick checks.
