Brutefence

BruteFence is a security tool that protects Windows servers and workstations from RDP brute force attacks. It runs as a Windows service, monitors failed login attempts in real time, and automatically blocks offending IP addresses via Windows Firewall—all locally, with no cloud dependencies.

• Real-time monitoring as a Windows service. BruteFence operates as a background Windows service that constantly scans security event logs for failed RDP authentication attempts. This ensures immediate detection of password guessing attacks without requiring manual intervention or keeping an application window open.
• Automatic IP blocking via Windows Firewall. Once an IP address exceeds the configured failed attempt threshold, BruteFence automatically creates a blocking rule in Windows Firewall. This integration stops all further traffic from that IP at the network level, effectively neutralizing the attack source.
• Configurable failed attempt thresholds and ban duration. Administrators can precisely define how many failed logins (e.g., 3 attempts) trigger a block and set the ban length—from permanent to temporary durations like 1 or 24 hours. This flexibility allows tailoring security policies to specific environments.
• IP whitelist for trusted connections. To prevent locking out legitimate users or administrative workstations, BruteFence supports an IP whitelist. Any address added to this list is excluded from monitoring and blocking, ensuring uninterrupted access from trusted locations.
• Transparent event logging and dashboard. All activities, including failed attempts, blocks, and whitelist hits, are logged and displayed in a clear interface. This provides full visibility into attack patterns and software actions, essential for security audits and incident analysis.
• Multi-language interface. The application is fully localized in English, Hungarian, and German. It automatically matches the system's display language, removing language barriers for international IT teams and administrators.
• Automatic updates. BruteFence includes an auto-update feature that periodically checks for new versions and notifies administrators. This ensures the software remains current with the latest security improvements and compatibility fixes without manual oversight.
• 100% local operation with no telemetry. All monitoring, decision-making, and blocking occurs entirely on the local machine. No data is transmitted to external servers, and there is no telemetry—guaranteeing complete privacy and data sovereignty for sensitive corporate networks.
• EV Code Signed installer. The setup executable is signed with an EV Code Signing certificate from Certum. This eliminates SmartScreen warnings during installation and verifies the software's integrity and publisher authenticity, building trust before deployment.
• Broad Windows platform support. BruteFence runs on Windows 10/11 Pro workstations and all modern Windows Server editions (2016, 2019, 2022, 2025). This wide compatibility makes it suitable for diverse environments, from small offices to enterprise data centers.
• VPS and cloud server protection. Specifically designed to secure Internet-exposed Windows machines, such as virtual private servers (VPS) and cloud instances. BruteFence automatically handles the constant brute force attempts targeting open RDP ports on public IP addresses.
• Free 7-day trial with no credit card required. BruteFence offers a fully functional 7-day trial period without requiring payment information. This allows thorough testing in the production environment before committing to a license purchase.

Development of BruteFence began in response to the persistent threat of RDP brute force attacks against Windows systems. The software is primarily written in C# and built on the Microsoft .NET framework to ensure deep integration with the Windows operating system and its security components. Created by a Hungarian development team, the first versions were released in the early 2020s with a focus on simplicity and effectiveness. The development philosophy has consistently emphasized local processing, privacy, and seamless integration with native Windows features like Event Viewer and Windows Firewall.
