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. The table below shows how to size the hardware for each software component:
| Component | CPU Speed (> GHz/core) |
CPU Cores (> cores) |
RAM Size (> GB) |
HDD Size (> GB) |
HDD/SSD Speed (> Mbytes/s) |
Network Adapter (Vendor, Model) |
|---|---|---|---|---|---|---|
| Console | High | High | High | Very High | Very High | Very Low |
| Packet Sensor | Very High | High | Medium | Low | Low | Very High |
| Flow Sensor | Low | Low | High | Very High | Medium | Very Low |
| SNMP Sensor | Very Low | Low | Very Low | Very Low | Very Low | Very Low |
| Sensor Cluster | Medium | Medium | Medium | Very Low | Very Low | Very Low |
| Packet Filter | Very High | Very High | Medium | Very Low | Very Low | Very High |
| Flow Filter | Low | Low | High | Very Low | Very Low | Very Low |
| Filter Cluster | Medium | Medium | High | Very Low | Very Low | Very High |

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:
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 9 or 10 (commercial), Rocky Linux 9 or 10 (free, RHEL-based), AlmaLinux 9 or 10 (free, RHEL-based), Debian 11, 12 or 13 (free, community-supported), Ubuntu 20, 22, 24 or 26 (free, Debian-based).
Wanguard installs itself under /opt, so make sure the root partition has at least 10 GB free space.
