Why Choose This Project

In today’s cybersecurity landscape, malicious IP addresses constantly change and attack networks in real time. Traditional static blocklists are often outdated, leaving systems vulnerable to unauthorized access, brute-force attacks, and bot traffic. This project provides a real-time IP blocklist updater, ensuring that firewalls, web applications, and internal systems always have the latest threat intelligence and automatically block malicious IPs. It’s ideal for enterprises, hosting providers, and security operations centers.

What You Get

A secure system that continuously fetches updated IP threat feeds, merges them into a consolidated blocklist, and distributes them to firewalls, web servers, or network appliances. Admins can monitor blocked IPs, track updates, and configure custom rules for automated blocking.

4. Distribution

   • Push updated blocklist to firewalls, web servers, or applications in real time.

5. Logging & Alerts

   • Maintain a log of blocked IPs, feed sources, and update timestamps.

   • Notify admin for anomalies or failed updates.

6. Dashboard Visualization

   • Display real-time blocklist stats, new threats, top blocked IPs, and update history.
