It’s hard to imagine a modern business taking place anywhere else but online. Most companies, organizations, and professionals directly depend on the performance of their websites, and any kind of security issue can cause catastrophic consequences.

DDoS attacks are becoming one of the major safety threats. Their number is constantly on the rise, as is the number of long-duration attacks. At the same time, the average size of DDoS attacks is increasing steadily and approaching 1 Gbps, which is enough to take most organizations completely offline.

What does it mean for you as a webmaster? Well, the answer is obvious – you need to do everything it takes to prevent DDoS attacks. We will show you how to do it in this post.

DDoS Attacks Explained

Before we reveal the top 10 anti-DDoS tools, we must explain to you how they work in the first place. As defined by TechTarget, distributed denial-of-service (DDoS) attack is an attack in which multiple compromised computer systems attack a target, such as a server, website or other network resources, and cause a denial of service for users of the targeted resource.

The fact that the incoming traffic comes from so many different sources is making it much harder to halt the attack by blacklisting one IP address. There are three types of DDoS attacks – traffic, bandwidth, and application attacks – but each comes with a purpose to create a smokescreen for other fraudulent actions.

In general, webmasters can protect their sites by doing the following:

  • Buy a dedicated server to ensure more bandwidth and security
  • Update regularly to keep the content management system, plugins, and other tools safe and stable
  • Create blacklists to ban suspicious IP addresses
  • Train staff to recognize DDoS attacks and react quickly
