Sentinel AI is a Windows security suite built to detect and investigate suspicious activity, monitor security-critical system behavior, contain threats, manage quarantine, and support verified remediation. Decide For Us gives couples and friends two good plans so they can stop scrolling and go.

Sentinel AI works alongside Microsoft Defender, which remains the antivirus and antimalware engine. Choose the app that solves the problem you have right now.

WINDOWS SECURITY SUITE

Sentinel AI

Security that goes beyond antivirus. Detect suspicious behavior, investigate what is happening, contain threats, quarantine suspicious files, and verify remediation.

βœ“ Continuous security monitoring across processes, network activity, services, startup items, scheduled tasks, persistence signals, authentication evidence, Defender, and Firewall status
βœ“ Threat investigation & correlation that connects system evidence and suspicious behavior instead of showing isolated raw data
βœ“ Containment & quarantine with controlled firewall actions, file isolation, restore capability, verification, and rollback safeguards
βœ“ Verified remediation & repair designed to confirm outcomes before Sentinel reports that an action succeeded
βœ“ Ask Sentinel adds an AI investigation layer grounded in current system evidence and verified history

Sentinel AI is the security suite. Microsoft Defender supplies the built-in Windows antivirus/antimalware engine; Sentinel AI works alongside it to provide broader monitoring, investigation, containment, quarantine, remediation, and security intelligence.
