## Core Features

- **Automatic Attacker Blocking**: Creates Windows Firewall rules after failed Remote Desktop login attempts (default threshold: 2 failures)
- **Continuous Monitoring**: Tracks Event ID 4625 (failed Remote Desktop logins) in Windows System Log in real time
- **Honeypot Traps**: Decoy ports (e.g., 3390, 3391) that permanently ban any attacker on first connection

- **Auto-update System**: Seamless updates with multilingual changelog display
- **7-Day Free Trial**: Full functionality, no credit card required
- **No Telemetry**: All logs stay local; only license validation and update checks transmit minimal technical data

## How It Works

1. **Continuous Monitoring**: Watches Windows Security Log for Event ID 4625 (failed logon)
2. **Threshold Detection**: Counts failed login attempts per source IP (configurable, default 2)
3. **Automatic Blocking**: Creates a Windows Firewall rule blocking the offending IP
4. **Honeypot Protection**: Optional decoy ports trigger an instant permanent ban on any connection
5. **Statistics Dashboard**: Aggregated attack analytics, trends, and per-IP history

## System Requirements

- **OS**: Windows Server 2016 or later, or Windows 10/11 Pro
- **RAM**: 2 GB minimum (BruteFence itself uses < 50 MB)
- **Disk**: 100 MB available space
- **Privileges**: Administrator rights required (for firewall rule management)
- **Firewall**: Windows Firewall must be enabled

## Security & Privacy

- **Local Logging**: All attack logs and statistics stored locally only
- **No Telemetry**: No usage data, attack logs, or personal information transmitted
- **License Validation**: Minimal technical data only (version, license key, hardware fingerprint)
- **Update Check**: Version number transmitted only during auto-update checks
- **GDPR-Friendly**: Designed to support compliance; website analytics optional with hashed IP, software has zero analytics
- **SHA256 Verification**: All releases include public SHA256 hashes for integrity verification
- **HTTPS Only**: All communication encrypted (TLS)
- **IP Hashing**: IP addresses hashed with SHA256 before any storage/transmission
- **DPAPI Encryption**: Registry data encrypted using Windows DPAPI
- **No Personal Data**: No collection of usernames, passwords, or personal information

## Installation & Setup

### Quick Start

1. Download installer from https://brutefence.com
2. Run with administrator privileges (installer is EV-signed, no SmartScreen warning)
3. Follow the setup wizard (intelligent defaults, no configuration required)
4. 7-day trial starts immediately — no license key needed

### SHA256 Verification

After download, verify the installer hash:

```powershell
Get-FileHash BruteFence-Setup.exe -Algorithm SHA256
```

Expected hash for current release: `61F38C45732C108895241A380667D0F88FAE5609C6823F0A69FB694F3C38E426`

### Configuration Options

- **Default Settings**: Intelligent defaults, no configuration required
- **GUI Management**: Simple settings interface for threshold tuning
- **Whitelist Support**: Exclude trusted IP addresses from blocking
- **Custom Honeypot Ports**: Add additional decoy ports

### Best Practices

1. Use strong passwords — BruteFence reduces risk but does not eliminate it
2. Change RDP from default port 3389 (optional, but recommended)
3. Enable Network Level Authentication (NLA)
4. Combine with VPN for maximum security
5. Enable auto-update for latest security fixes
6. Review attack statistics regularly

## Licensing & Pricing

- **Trial**: 7 days free, full functionality, no credit card
- **License Model**: Annual subscription per machine, hardware-bound
- **Payment**: Contact support@brutefence.com for pricing
- **Refund Policy**: 30 days from purchase
- **Renewal**: Auto-renewal, can be cancelled anytime

## Advanced Usage

### Threshold Tuning

- **Conservative** (2-3 attempts): Strict protection, higher false positive risk
- **Balanced** (5 attempts): Recommended for most scenarios
- **Permissive** (10+ attempts): Lower false positives, slower response

### Honeypot Configuration

Add decoy ports that attackers commonly scan:

- Port 3390 (RDP+1)
- Port 3391 (RDP+2)
- Port 22 (SSH — often probed even on Windows servers)

Any connection attempt to a honeypot port results in an instant permanent ban.

### Integration

- **WHMCS License Management**: Automated licensing for hosting providers
- **PowerShell Automation**: Script-friendly for bulk deployments
- **System Log Integration**: Compatible with existing SIEM and monitoring tools

## Common Questions

**Q: What is BruteFence?**
A: BruteFence is professional protection software for Windows Remote Desktop. It monitors failed login attempts (Event ID 4625) and automatically blocks malicious attackers through Windows Firewall integration.

**Q: How does automatic blocking work?**
A: BruteFence watches Windows System Logs for Event ID 4625. When an attacker exceeds the threshold (default 2 failures), it creates a Windows Firewall rule blocking that source IP.

**Q: Does it slow down my computer?**
A: No. Resource usage is minimal (< 50 MB RAM). System monitoring is efficient and non-intrusive.

**Q: Can legitimate users be blocked?**
A: Yes, if they exceed the threshold. Use the whitelist for trusted addresses, increase the threshold, or reset firewall rules manually.

**Q: Does BruteFence replace other security measures?**
A: No. It is a complementary defense layer. Continue using strong passwords, NLA, VPN, and other security best practices.

**Q: What data is collected?**
A: None. All logs stay local. Only license validation and update checks transmit minimal technical data (version number, license key).

**Q: Is BruteFence the same as a fence charger or agricultural product?**
A: No. "BruteFence" is a Windows computer security software product. It is unrelated to electric fences, livestock, or agricultural equipment.
