RayzsShield Anti VPN,Crash,DoS

The most unique Spigot protection plugin on the market!
Against (Netty-)Crasher, VPNs, Exploits, Hacked-Crash-Items, and Ping/Bot-Attacks!

RayzsShield is a highly advanced, ad-free, and customizable Minecraft security plugin with a lot of extra features.
This plugin protects your server against (Netty-)Crashers, VPNs, Exploits, Hacked-Crash-Items, and Ping/Bot-Attacks!
It's easy to configure and works for every Minecraft spigot server version between 1.8-1.12 & 1.14-1.19!

A lot of servers are already trusting in RayzsShield! ^^
Here is a small statistic from bStats:

Included features:
Many in-game commands to manage the plugin!
You can replace /rs with something like #anticrash to personalize the plugin to your own! This can be changed in the plugins/RayzsShield/messages.yml at messages.admin.command!
[permission: rayzsshield.admin]
For each command, the permission is: rayzsshield.admin.xxx (it should be self-explainable)

Get an in-game notification when someone tries to crash the server!
You can toggle receiving notifications with this command:
/rs notify [permission: rayzsshield.admin.notify]

Get notified via a discord-webhook notification when someone tried to crash the server!

This is what the player sees:

You can change the kick-message in the messages.yml under messages.alert.kickplayer.message!

Execute a command through the server console after the player tries to lag/crash the server:

Toggle checks and reload the plugin in a GUI!
To open this GUI you need to execute this command:
/rs gui [permission: rayzsshield.admin.gui]

Get an in-game actionbar for small statistics when someone is botting/spam-pinging your server.
You can toggle receiving the actionbar with this command:
/rs verbose [permission: rayzsshield.admin.verbose]

You can disguise the plugin to pretend it's something else or completely vanish it from the server. (/pl, /plugins)
To vanish the plugin from the plugin list, you need to enable the option: to hide

The extra-feature Backfire means, that the player receives a message after he tried to crash the server:

To detect and fix new crasher/ping-exploits RayzsShield includes a PacketLogger!
If your server got crashed and you have enabled the PacketLogger, you can send this file to me and I can fix this crasher easily:

For those who want to create a test server with RayzsShield:

Almost EVERYTHING is configurable!

_________________________________________

Why are the features not working? (e.g: GUI isn't opening)
It's because you haven't put your license key in the config.yml!
Without the license key, all Premium-Features are deactivated and you're using the lite version of RayzsShield without it.
To get your license key please join my discord server and ask for your license key! I will ask you to prove your purchase by asking for your PayPal transaction and your BuiltByBit-Username. After this process, you'll get your license key as fast as possible!

Why does it not block any Bots/Ping-Attacks?
Of course, you'll have to enable those features by yourself in the config.yml under "checks.server.TCPFlood|AntiBot".
TCPFlood = AntiNullPing
AntiBot = AntiBot & AntiVPN (you have to enable the module "antivpn" as well if you want to use the VPN-Detection!)

I have a bug or suggestion!
Please join my discord server for things like this.
I LOVE to improve RayzsShield and for that, I need YOUR opinion!
So please don't be shy and tell me what you don't like about RayzsShield and how I can improve this. This would help me a lot!

How to enable RayzsShield-Premium after purchase
All RayzsShield-Premium features will only work when you insert the license key!
Here are a few steps:

⌲ Join my discord server.

⌲ Create a Ticket and send your Paypal transaction & your Username in this channel.
⌲ Wait until your license key is ready. (Can take up to 24 hours)
⌲ Insert the license key in the config.yml under "license: insert-key-here"
⌲ Restart the server to load the configuration file fully.

[!] Make sure that your server has a stable internet connection!
RayzsShield is connecting to my webserver (rayzs.de) to check your license key and for new updates.

This website is not collecting any data on purpose but it might be that the hosting provider or CloudFlare
is using information like the IP address or the user agent of the web connection!

___________________________________________________________________________________________________________________________

Of course, you can suggest new features on my discord server so that I can improve the plugin.
I do not guarantee to add every suggestion I get!

Small information

This is the Premium version of this plugin and includes a lot of extra features!

If you want to be protected but don't wanna pay for it, you can use the lite version of RayzsShield for free!

(not available yet)

But why did I make a lite version of RayzsShield which is free to use?

The main reason for RayzsShield was to be a plugin that gives the player default protection against crashers. But most of those plugins are just paid (too expensive) or completely bad/poorly coded.

With this plugin, I want to help everyone else here who hasn't enough money to afford a basic-protection plugin. (like me 3 years ago)

This Premium-Ressource does only have a lot of extra features which the lite-version doesn't have!
