A cordon between your services and unwanted connections
Kordon blocks VPNs, proxies, bots and suspicious clients in milliseconds. Legitimate players join without delay.
We stop unwanted connections at the door
Rule-breakers never reach your server, and legitimate players don’t even notice the check.
How it worksMalicious connections blocked
Trusted by
Four threats Kordon keeps off your server
VPN
They hide the real IP and country. One person joins on a dozen accounts.
Proxies
Hundreds of rotating addresses for dodging bans and running bot attacks.
Bots
They scan your server, harvest data and take legitimate players’ slots.
Suspicious clients
Clients that pretend to be Minecraft: Java Edition are recognised on connect. Known cheaters are kept off your server.
Protection that needs no special knowledge or complex setup
Live in a couple of minutes
No configs or technical skills needed: install it and your server is protected.
Kordon’s own database
Global blocking: VPNs and bots detected on any Kordon server are automatically blocked on yours too.

Minecraft servers, websites and any of your services.
Add your server in the client area, put Kordon.jar into the plugins folder of your BungeeCord, Waterfall or Velocity proxy and restart it. Kordon checks every connection and keeps out VPNs, proxies and bots, while regular players join as before.
BungeeCord, Waterfall and proxies built on them, plus Velocity 3.4 or newer. It needs Java 21 or newer. Kordon protects Minecraft: Java Edition only; standalone Paper and Spigot servers without a proxy are not supported yet.
No. Any server owner can do it in a couple of minutes.
By behaviour and addresses, while legitimate players get in as usual.
Yes. When a wave of bots hits your server, Kordon switches to attack mode and shuts out the networks they come from. Bots caught on one Kordon server are blocked on all the others too.
Clients that only pretend to be Minecraft: Java Edition (for example, modified mobile builds) and players Kordon knows as cheaters. Players who join through Geyser and Floodgate are not affected. Kordon is not an anticheat and does not watch what a player does in the game.
Add them to the allow list and they can join right away.
Yes. At first Kordon only flags rule-breakers and blocks no one.
You don't need to get API keys or edit configs. Kordon has its own address database shared by every server, a login log in the client area and ready-made protection levels instead of hand-tuned rules.
The account moves to Free and all data is kept.
