According to statistics, 33% of businesses fall victim to DDoS attacks. It is almost impossible to predict such attacks. Some of them can be powerful and reach 1.35 TBps. According to Incapsula, DDoS attacks cost businesses around $40,000 per hour. Based on the Akamai security report, most DDoS attacks come from China.

The following resources will help you calculate the losses caused by DDoS:

Cybercriminals resort to different methods of conducting DDoS attacks that may include:

  • UDP Fragmentation
  • CharGEN attacks
  • NTP, DNS, UDP, SYN, ACK, SSPD flood
  • TCP anomalies

So, you need to take care not only of layer 7 attacks but ensure that all web applications are protected at all layers.

To protect against DDoS attacks, businesses and individual website owners can use specialized services. Some of the best solutions are listed below.

Silverline monitors incoming traffic substantially weakens DDoS attacks and reduces the number of false positives in 24/7 mode. If BIG-IP and DHD devices are installed on the customer's site, then when an attack is detected, information about it is transmitted to the cloud and suppression of the attack begins at the cloud level.

10. Radware DefensePro

Radware DefensePro is a line of network devices designed to protect against DDoS attacks of any type. In addition, Radware may offer DDoS protection based on SaaS.

Radware DefensePro advantages are:

  • Dedicated hardware platform to prevent high volume DDoS attacks, without impacting legitimate traffic
  • SSL attack mitigation solutions that protect from all types of encrypted attacks.
  • Behavioral analysis of attacks and automatic routing to ensure the best mitigation.
  • The ability to protect against most attacks with default settings without the need for complex configuration.


Today's market offers a wide range of protection solutions. If the company's infrastructure is not limited to the website and is constantly exposed to external attacks, it is worth considering a hardware solution for autonomous protection against DDoS attacks and signing a contract with a telecom operator.

A universal option is to use cloud protection services. It is suitable for small companies that run just websites and do not have sufficient funds or qualified personnel for self-protection.

When choosing a DDoS protection service, businesses should first evaluate their online audience and possible monetary impact from DDoS attacks.

Pricing structure in this niche differs greatly. Some services are based on a total number of monthly mitigations; others are based on hours of mitigation, some are priced according to the bandwidth, etc. Each pricing model favors different needs.

Selecting a DDoS protection solution, the choice should be based on the size of the infrastructure and budget. The best quality of protection is promised by Akamai Technologies, but their services are rather expensive. CloudFlare is the leader in the low-price segment, while Imperva is in middle position.

When choosing hardware solutions, it is worth paying attention to their cost, technical characteristics, and efficiency. Radware is among recognized market leaders, but its solutions are not cheap.
