Terabit DDoS Attacks Need State-of-the-Art Terabit DDoS Mitigation — Are you ready?

In recent years, distributed denial of service (DDoS) attacks have become more frequent and sophisticated. Attackers continue to find new ways to flood target networks with massive-scale attacks that grow exponentially and cross the terabit attack rate. This has become a major concern for enterprises and carriers worldwide and Radware is the only vendor holding the on-prem mitigation answers to these massive attacks.

The impact of these hyper volumetric DDoS attacks can be devastating — they cause extended downtime, financial losses and reputational damage. That’s why it’s critical that organizations are prepared to detect and mitigate these vicious attacks with a state-of-the-art mitigation on-prem platform.

3 Reasons Why You Need an Ultra-High-End Mitigation Platform

1. The Terabit DDoS Attack Era Is Here

In the world of cybersecurity, distributed denial of service (DDoS) attacks have become increasingly sophisticated and damaging. One of the emerging trends of DDoS attacks is hyper volumetric floods; these attacks generate traffic of over a staggering 1Tbps (terabits per second). Terabit DDoS attacks are a significant threat to organizations. They can quickly overwhelm a network infrastructure and disrupt critical services. As a result, implementing a state-of-the-art terabit DDoS mitigation solution is crucial for organizations to protect themselves against these devastating attacks.

Here are some of the largest recorded volumetric attacks:

  • Google Services was targeted with a volumetric attack of 2.54Tbps.
  • Amazon AWS Infrastructure was targeted with a 2.3Tbps attack.
  • Microsoft Azure reported three terabit attacks: one of 3.47Tbps and two others that were over 2.5Tbps.

In May 2021, Radware Cloud Services successfully mitigated a hyper volumetric DDoS attack that peaked at almost 1.5Tbps. This volumetric, carpet-bombing attack against the targeted subnet lasted for thirty-six hours. It had a sustained throughput of over 700Gbps for more than 8 hours.

The total volume generated by this attack was 2.9Pbps, which was one-and-a-half times the information contained in all U.S. academic research libraries. And it was all successfully blocked.

Terabit volumetric floods are here to stay, and a proper mitigation device is a must!

2. Nielsen’s Law of Bandwidth Capacity still holds true

Nielsen’s Law of Internet Bandwidth states that a user’s bandwidth grows 50% each year. It has held true for the past 40 years, from 1983 to 2023. This, along with 5G and 6G networks moving forward, proves human consumption and needed speed rate demands are enormous. Rest assured this won’t slow down any time soon.

To support this increasing demand, data centers, carriers, service providers and cloud platforms must keep up with the vast amounts of data. They have already adopted the latest network technology that has introduced 400G network infrastructure for high bandwidth and faster data transmission speeds. What’s needed is a DDoS mitigation platform that will support these high throughput rates. They will need to keep up with the demanding throughput by having 400G data ports that can sustain and process detection and mitigation.

3. Scale And Performance for Unbeatable Mitigation Capabilities

So, how can you protect your organization against Terabit DDoS attacks that send huge amounts of traffic toward your assets all at once?

The answer lies in implementing a scalable and robust state-of-the-art DDoS mitigation solution. Ensure the vendor you choose offers protection level tiers. To achieve unbeatable levels of mitigation against Terabit DDoS attacks, deploy the following:

a. Multi-Layered Protection

A multi-layered approach is crucial in mitigating Terabit DDoS attacks. This involves deploying a combination of the right network infrastructure, a mitigation appliance that can handle ultra-high-end rates and cloud-based solutions to ensure you have a diverse range of defenses.

b. Traffic Scrubbing

Traffic scrubbing involves filtering out malicious traffic from legitimate traffic, enabling your network to remain online during an attack. A dedicated and robust DDoS mitigation hardware platform is great for combating Terabit DDoS attacks, but that isn’t enough. On the software side, you need a behavioral DDoS countermeasure approach to make sure attacks are quickly detected and traffic is automatically filtered. This lets legitimate traffic in while keeping attack traffic out.

c. High Port Density, Scale and Performance Without Compromise

To handle huge amounts of traffic, whether during peacetime or while under attack, the mitigation platform hardware and software must be capable of handling high volumetric rates; very few can accomplish this.

Picking the right platform is key. Whether deploying the detection and mitigation platform inline or out-of-path will ensure a sustainable, clean and DDoS-free environment for customers.

To protect large network infrastructures, such as carriers, Tier-1 service providers and large enterprises, the mitigation platform must support high port density to inspect incoming traffic, remove threats and pass legitimate traffic to the protected network without creating a bottleneck. It should include several 100G data ports, and, if possible, 400G data ports. This will enable it to accommodate large network infrastructures.

d. High Visibility and Simplified Management

Having high visibility and simplified management are crucial aspects of a DDoS mitigation platform. High visibility of the network and packet flow ensures that network administrators have clear and concise information, whether during peacetime or during an attack. Information should include the attack’s origin, the type of attack and the impact on the network. This information is vital in helping administrators make informed decisions on how to best mitigate the attack and reduce damage(s). Additionally, simplified management makes it easier for administrators to configure and manage the DDoS mitigation platform efficiently. This is particularly important in high-pressure situations where time is of the essence; the faster mitigation is implemented, the better. Having the right management solution that allows you to gain visibility and control your high-end mitigation platform(s) is critical. The right high-end mitigation platform, along with a great management and analytics system, ensures organizations can effectively and efficiently protect their networks from Terabit DDoS attacks. Doing so will minimize disruptions to operations and ensure systems and customers remain up and running and are secure.


Threats from Terabit DDoS attacks continue to grow. These hyper-volume attacks mean organizations need to take the necessary steps to protect themselves. By implementing a multi-layered approach, traffic scrubbing with the right mitigation platform, scalable infrastructure readiness and relying on a seamless, easy-to-use management system, organizations can greatly reduce the risk of a devastating attack.

Remember, prevention is always better than a cure. That’s why it’s crucial to be proactive when protecting your network from massive, overwhelming Terabit DDoS attacks.
