Before you install

Public beta - many features are still being refined; expect changes between releases.
Administrator privileges required for install and service.
Npcap is not included - install separately from npcap.com for live packet capture (WinPcap API-compatible mode recommended).
Suricata is not included - optional IDS/IPS you install and configure yourself; CustosXI only reads alerts when enabled.
PostgreSQL, GeoLite2 databases, and threat feeds are not included - optional add-ons you configure in Settings.
The installer bundles CustosXI, .NET 10, and Windows App SDK Runtime (when needed). See Third-party notices.
Windows SmartScreen may warn on unsigned beta builds - see Verify your download.

Network emergency?

If DNS or firewall blocks cause trouble, see the emergency recovery guide (restore DNS and unblock IPs from the app or Windows).
