Understand the signal
Sentinel learns normal network patterns and combines them with threat heuristics. Risk scores and alert reasons help you investigate changes.
Choose your response
Trust a known program, stop a process or, with Pro and the required permissions, block a remote address through your operating system firewall.
Risk scores are indicators for investigation. Network monitoring cannot prove that a program is safe or malicious and does not replace antivirus protection.

Local by design
Your monitoring workspace.
Settings, learned profiles, alerts and connection history are stored on your computer. Optional AI explanations are sent to the model server you configure in Settings; choose a local server to keep that analysis on your device.
Host-name lookups can contact your configured DNS service. Your operating system controls which process and connection details Sentinel can read.
Get started
From install to insight.
- Download and install the package for your computer.
- Open Andromeda Sentinel from the Start menu or application launcher.
- Review live connections and let the behavioural model learn your normal activity.
- For Pro AI features, activate your licence and connect your local model in Settings.
Before you get started.
Does Sentinel block connections automatically?
Firewall blocking is a manual Pro action. Review the address and process first: stopping a process or blocking a destination can interrupt useful applications. Windows uses Windows Defender Firewall; Linux uses iptables or ip6tables. Linux firewall rules may be cleared on reboot unless your system saves them.
Why are some process details missing?
Your account may lack permission to inspect other users' processes. Running with administrator or root permissions can improve visibility and enables firewall control. Keep the app running to collect new connections.
Is an AI model required?
Free monitoring, behavioural scoring and rule-based alert reasons work without an AI model. Pro AI explanations and chat require a reachable model server and a model you install separately. AI output can be inaccurate; review it before taking action.
Why is a download unavailable?
Downloads activate only after a desktop package passes its build checks and is published. Windows and Linux may become available at different times. Reload this page to check the current release.
