Distributed denial-of-service (DDoS) attacks are becoming a major issue for many businesses, from small and midsize to large enterprises. The size of the attack has also been on the rise, with attacks exceeding 2Tbps in size. Cloudflare reported a 15% quarter-on-quarter (QoQ) and a 67% year-on-year (YoY) increase in ransom DDoS attacks in Q3 2022.

There was also a significant surge in Layer 3 and 4 DDoS attacks, with an increase of 97% YoY and a 24% QoQ. The most common targets of these attacks were the gaming industry, telecommunications, and information technology and services, including the software industry.

These industries are often targeted because they store data that can be sold on the black market, creating a new revenue stream for cyber criminals. With such high costs associated with DDoS attack protection, it is essential to find ways to reduce business exposure and minimize damage from this type of cyberattack.

However, not all DDoS protection service providers offer the same level of security or features. Businesses should carefully evaluate their needs before choosing one over another, weighing factors such as the cost of ownership of security controls against potential impacts if an attack is successful.

What is a DDoS Protection Service?

DDoS protection services are a form of cybersecurity that protects against DDoS attacks. A DDoS attack occurs when a third-party attempts to overwhelm the computer system(s) with fake requests, rendering the service unavailable to genuine users. There are various ways in which this can be done, such as by directing traffic from numerous sources towards the same target to overload it and cause it to become non-functional.

In some cases, there might be up to hundreds or even thousands of different sources, each transmitting data at high speeds and all competing for a response from the targeted machine. In other cases, attacks can be more targeted and use just one or two sources, although still at very high volumes.

Top DDoS Protection Providers

DDoS protection services are an essential part of any business. They protect the network from being the victim of an attack that could disrupt enterprise service, steal customer data, or even destroy systems. The following is a list of the leading companies that offer DDoS protection service.

How to Choose a DDoS Protection Provider

Choosing the right provider is a challenging task. There are many factors to consider, such as customer service, cost, reputation, and features. Some providers will be more suitable than others depending on what you need from your provider.

To make an educated decision when choosing your provider, it is essential to research your options before making a decision. You should also read reviews from people who have used the provider before to get a feel for how satisfied they were with their experience. You can find the best fit for your needs by doing this.

Before making your selection, you can also ask yourself some pre-qualification questions when shopping for the best DDoS protection services:

  • What is the cost of the service?
  • How much bandwidth do you need?
  • Does it offer 24/7 support, and does that support include in-house experts or just customer service representatives?
  • If using the cloud, what kind of servers does it provide, and how many are available at each location? If using hardware, what type of hardware does it provide, and how many pieces are needed to protect against an attack?
  • How long does it take for support staff to respond and fix the problem if there is downtime?
  • Does it have data centers in various locations around the world?
  • Does it have unlimited data usage, or will it limit the traffic from one IP address?
  • Can it block attacks that use different protocols, such as UDP, ICMP, or SYN floods?

Answering these questions beforehand will help you pick a service with the essential features for your business needs.
