DUAL-TIER WINDOWS DEFENSE

Zero-Effort for You.
Mathematically Unbreakable for Intruders.

Ordinary app lockers are easily terminated through Task Manager or Safe Mode reboots. PrivaGuard combines a simple 60-second user workflow with unkillable Windows NT Kernel service architecture, Process DACL hooks, and silent forensic sentinels.

TWO WAYS TO UNDERSTAND

Designed for Simplicity. Engineered for Defense.

Toggle between the effortless 60-second user workflow and the low-level Windows kernel engine powering it.

STEP 01

1-Click Silent Setup

Lightweight native C++ installer (<12MB). Installs cleanly in under 5 seconds without asking for bloated runtimes, third-party drivers, or Microsoft account registrations.

  • Zero Windows Registry Bloat
  • 100% Offline Standalone Binary
  • Starts Silently on Windows Boot
STEP 02

Toggle Target Apps & Vaults

PrivaGuard automatically discovers installed browsers, communication apps, and sensitive directories. Simply flip the switch next to any application or secret folder you wish to guard.

  • WhatsApp, Telegram & Discord
  • Google Chrome, Edge & Brave
  • VS Code, Terminal & Secret Files
STEP 03

Walk Away With Peace of Mind

Lock on idle automatically from 30 seconds to 5 minutes, or hit your stealth global hotkey. The second you return, unlock instantly with your Master Password or PIN in under a second.

  • Fast Hotkey Lock: Ctrl + Shift + Alt + P
  • Instant PIN & Password Unlock
  • Silent Intruder Webcam Snaps if Guessed
DACL HOOK IMMUNITY

Admin CMD Taskkill Immunity

On startup, PrivaGuard applies a custom Discretionary Access Control List (DACL) via the native Windows SetKernelObjectSecurity API. This systematically strips PROCESS_TERMINATE (0x0001) and PROCESS_SUSPEND_RESUME (0x0800) rights from standard users and Administrators alike.

C:\Windows\System32> taskkill /F /IM privaguard.exe
ERROR: Access is denied. Protected by Process DACL Hook.
WINDOWS NT SERVICE

Session 0 True System Service

Unlike basic tray apps that terminate when a user logs off or gets suspended, PrivaGuard runs as a native Windows Service under NT AUTHORITY\SYSTEM in isolated Session 0. Cross-session communication is achieved via authenticated Named Pipes with 1.5s cryptographically validated heartbeats.

SYSTEM\CurrentControlSet\Services\PrivaGuardService
Status: RUNNING • Recovery: SCM Auto-Restart (1000ms)
50MS RECOVERY

Self-Healing Config Shadow Vault

User configurations are hardened with NTFS Deny DELETE permissions. Multi-hive signed HMAC-SHA256 shadow backups are synced across %PROGRAMDATA% and registry hives. An active ReadDirectoryChangesW worker detects external tampering in <1ms and restores authentic state in <50ms.

ShadowSync: HMAC-SHA256 Authenticated
Tamper Event Detected → Restored in 0.042s from Vault
SAFE MODE SENTINEL

Safe Mode Boot & Anti-Debugging

PrivaGuard registers within Windows SafeBoot\Minimal and Network registry hives. When SM_CLEANBOOT is detected, defensive postures escalate instantly. PE checksum verification (MapFileAndCheckSumW) and PEB BeingDebugged traps abort cracking attempts.

INTRUDER INTERCEPTION LIFECYCLE

What Happens When Someone Tries to Snoop?

Trace the exact microsecond execution pipeline triggered when an unauthorized user attempts to open a protected app.

0.000s

Target Launch Attempt

An intruder or coworker clicks your WhatsApp, Chrome, or confidential folder icon while your laptop is unattended.

Target: WhatsApp.exe
0.008s

Kernel Window Interception

PrivaGuard's process watchdog intercepts the execution handle before the window can render sensitive messages. An impenetrable display shield blankets the target app.

0.015s

Cryptographic Authentication Challenge

User is prompted for Master Password or PIN. Credentials are hash-verified with 100,000 PBKDF2 rounds using constant-time comparison.

PBKDF2-HMAC-SHA256
<1.000s

3x Failed Guesses → Silent Forensic Capture

If an incorrect PIN is entered 3 times, PrivaGuard calls the DirectShow camera pipeline in <1s. It captures a crisp snapshot of the snooper silently with zero shutter sound.

Encrypted Evidence Outbox Dispatch

The forensic photograph, exact timestamp, and targeted app are recorded into pending_alerts.json. If offline, it queues safely and dispatches to your verified email the moment an internet connection is detected.
