CoreGuardian – Secure Your Server with Confidence
CoreGuardian is a lightweight yet powerful plugin designed to protect your Minecraft server from disruptive players and malicious attacks. While no plugin can guarantee 100% safety, CoreGuardian provides a strong line of defense and practical tools to keep your community safe.

✨ Key Features

Essential Security Tools
CoreGuardian comes with a simple but effective set of features that allow server owners to easily set up, configure, and manage protections. Commands are intuitive, user-friendly, and designed for quick access.

Discord Webhook Integration
Stay informed in real time. CoreGuardian can send alerts directly to your Discord server whenever suspicious activity is detected — such as unauthorized login attempts, name spoofing, brute-force exploits, UUID/IP spoofing, and more.

IP Reputation Check (IPQualityScore)
CoreGuardian integrates with the IPQualityScore API to detect and block suspicious or high-risk IP addresses before they can cause issues. This helps prevent VPN/proxy abuse and blocks unwanted traffic.

Folia Support
Whether you’re running a traditional Spigot/Paper setup or the next-generation Folia architecture, CoreGuardian is fully compatible.


Multi-Proxy Compatibility
Supports proxy and multi-server setups such as BungeeCord, Velocity, and others — giving flexibility to networks of all sizes.

⚠️ Important Note
CoreGuardian is a powerful protective measure, but not an absolute shield. There is always a small chance that determined attackers may find a way around it. If that happens, treat it as bad luck — not a flaw of the plugin itself.

Why Choose CoreGuardian?
If you’re looking for a plugin that’s simple, reliable, and adds an extra layer of protection to your Minecraft server — while keeping you updated through Discord — then CoreGuardian is the right choice.

✔ Protect your server.
✔ Keep your players safe.
✔ Build with confidence.
