SENTINEL AI · WINDOWS SECURITY SUITE

Monitor. Investigate. Contain. Remediate.

Sentinel AI is a Windows security suite built to help protect your PC beyond basic antivirus. It continuously monitors security-relevant activity, correlates evidence, investigates suspicious behavior, supports threat containment and quarantine, and verifies remediation outcomes. Microsoft Defender remains the antivirus/antimalware engine and Sentinel AI works alongside it.

Security capabilities

✓ Continuous monitoring: processes, network connections, services, startup items, scheduled tasks, persistence signals, authentication evidence, Defender and Firewall status

✓ Investigation & correlation: connect suspicious activity to verified system evidence and persistent investigation history

✓ Containment: controlled security actions using Windows mechanisms with verification and rollback safeguards

✓ Quarantine & restore: isolate suspicious files while preserving the ability to review and restore them

✓ Verified remediation: confirm outcomes before reporting that a security or repair action succeeded

✓ Ask Sentinel: an AI investigation layer grounded in current evidence and verified history—not a generic chatbot

How Sentinel AI and Microsoft Defender work together

Microsoft Defender Antivirus provides Windows malware and virus scanning. Sentinel AI does not pretend to replace that antivirus engine. Instead, Sentinel AI adds the broader security-suite layer around it: continuous monitoring, investigation, correlation, containment, quarantine, verified remediation, security history, optimization, and evidence-grounded guidance.

The simple distinction: Defender is the antivirus engine. Sentinel AI is the broader Windows security suite working alongside it.
