- Check signal and channels first; a free edition exists. Verify heatmaps, planning and commercial rights by edition.
- Free outbound firewall to identify connecting apps; network-filter approval required. Not a VPN.
- Alternative to LuLu for richer monitoring; commercial license, with session and monitoring limits in the trial.
- Capture only for protocol evidence; free/open source. Live Mac capture needs permissions; files may contain sensitive data.
