Defender is great antivirus. But antivirus isn't security hardening. WinSentinel audits your entire Windows configuration — the 30+ things Defender doesn't check.
💡 WinSentinel + Defender = defense in depth. They're complementary, not competitive.
Microsoft Defender answers: "Is malware running on this machine right now?"
WinSentinel answers: "Is this machine configured securely?"
A machine can have Defender fully active and still be wide open — UAC disabled, BitLocker off, RDP exposed without NLA, SMBv1 enabled, stale admin accounts, PowerShell in Unrestricted mode, firewall rules accumulated over years. Defender won't flag any of these. WinSentinel checks all of them.

CRITICAL
UAC set to Never Notify
Any program can silently elevate. Defender won't flag this.
CRITICAL
BitLocker not enabled on OS drive
Laptop stolen = all data exposed. Defender doesn't check encryption.
WARNING
RDP enabled without NLA
Pre-authentication attacks possible. Defender sees no malware here.
WARNING
SMBv1 still enabled
WannaCry vector. Defender may block the payload, but why leave the door open?
WARNING
3 stale admin accounts (90+ days inactive)
Lateral movement goldmine. Defender has no concept of account hygiene.
WARNING
PowerShell transcription logging disabled
Attacker PS commands leave no trace. AMSI alone isn't enough.
The best security posture uses both:
Think of it this way: Defender is the lock on your front door. WinSentinel checks that all the windows are closed, the alarm is armed, and you didn't leave the spare key under the mat.
