Build your own IP monitoring and Anti-DDoS Appliance

OVERVIEW: The quickest and most cost-effective method of protecting your network and services against DDoS attacks is by installing Andrisoft Wanguard on a spare, commodity server. The software can be installed easily, in just a few minutes, on any 64-bit server equipped with an Intel or AMD processor.

HARDWARE
REQUIREMENTS: 
Wanguard was designed to be completely scalable. It can be installed either on a single server with adequate hardware resources or on multiple servers distributed across the network. The exact hardware specifications needed for each Wanguard component are listed on each component page: Console, Packet Sensor, Flow Sensor and Filter.

USING VIRTUAL
MACHINES: 
You can use Virtual Machines during the trial period, but using dedicated servers for production is highly recommended.
A few arguments against using Virtual Machines to run Wanguard on a regular basis:
• Having fast and uninterrupted access to the hard disk is a critical requirement for the Console.
• The resources must be provisioned in a predictable and timely manner.
• Some Virtual Machines do not have a stable clock source.

OPERATING SYSTEM INSTALLATION:  Before installing Wanguard you will need to install (no advanced Linux skills required) on the designated server one of the following Linux distributions: Red Hat Enterprise Linux 7, 8 or 9 (commercial), CentOS 7 or 8 (free, RHEL-based), Rocky Linux (free, RHEL-based), AlmaLinux (free, RHEL-based), Debian 10, 11 or 12 (free, community-supported), Ubuntu 16, 18, 20 or 22 (free, Debian-based).

Wanguard installs itself under /opt, so make sure the root partition has at least 10 GB free space.
