What are DDoS Protection Solutions?

Distributed Denial-of-Service (DDoS) protection solutions help keep an organization's network and web services up and running when they suffer a DDoS attack. DDoS attacks are made with the intent to deny businesses access to network resources or to shut-down access to an organization's website or applications. These attacks are not intended to steal information or damage security measures, but simply to shut down or reduce the performance of their target website or application for the duration of the attack. For this reason, typical security measures are inadequate for preventing DDoS attacks. DDoS protection solutions are important for any business that relies on network technologies or provides online services.

DDoS attacks attempt to flood an organization's network with large volumes of traffic from bots or hijacked browsers. Because of this, most businesses do not have the bandwidth to withstand a DDoS attack with manual or on-premises solutions. Cloud based, or hybrid DDoS protection solutions protect businesses by identifying illegitimate traffic before it reaches an organization's network, and redirecting that traffic to their large volume of data centers. With a DDoS protection solution, legitimate users will be able to access an organization's web services but attackers will never reach the network infrastructure.

Illegitimate Traffic Recognition

To recognize illegitimate traffic, DDoS protection solutions monitor attributes and behaviors of normal users, such as IP addresses and cookies. The DDoS protection solution uses this information to distinguish between traffic from typical users and traffic that is unusual. When under attack, the DDoS protection solution can redirect traffic from users that do not match up with the observed attributes and behaviors of a typical user, ensuring that they do not flood an organization's network.

DDoS protection solutions are either active 24/7 or require manual activation. Constantly active DDoS protection solutions redirect illegitimate users automatically whenever there is an abnormal surge in traffic, while manual DDoS protection solutions must be activated by an administrator when an attack occurs.

DDoS Protection Solution Features and Capabilities

  • Infrastructure Protection (Layer 3/Layer 4)
  • Website Protection (Layer 7)
  • DNS Reflection Protection
  • DNS Amplification Protection

Pricing Information

Many DDoS protection solutions have a free version sufficient for smaller businesses that may not require 24/7 monitoring. For larger businesses, DDoS protection solutions usually offer a premium package for a monthly subscription. These packages typically include features like 24/7 monitoring, post-attack analysis, and greater access to the bandwidth of the protection service. Depending on the features desired, subscriptions can start as low as $100-200/mo but can easily reach into the thousands for the highest levels of protection.
