Top 8 DDoS Protection Service Providers for 2022

Distributed denial of service (DDoS) attacks can cripple an organization, a network, or even an entire country, and they show no sign of slowing down.

DDoS attacks may only make up a small percentage of security threats, but their consequences can be devastating. The country of Estonia was brought offline a few years back by a DDoS attack. Over the past year or so, Google, Amazon and Microsoft have been subjected to massive DDoS incursions. And DDoS attackers have adopted a tactic from ransomware groups and are seeking payment from victims and potential victims.

While there are some things security teams can do to lessen the impact of DDoS attacks, the growing sophistication of such attacks has sparked strong growth in the market for DDoS solutions, driven by the growth in DDoS itself.

Research by Cisco estimates the volume of DDoS attacks will surge from more than 10 million in 2021 up to 15 million by 2023. Meanwhile, the 2021 State of the Data Center Industry research report placed DDoS behind ransomware as the threats that most worry the enterprise.

According to Imperva Research Labs, DDoS attacks tend to come in waves. Recently, ransom DDoS attacks are being launched with the intent of disrupting the target by launching a DDoS attack to cripple the victim’s network and applications unless a ransom is paid. Often, the cybercriminals behind these threats will carry out a small attack to show that they are capable of what they’re threatening to do.

The most recent wave happened in December 2021. NetScout’s latest Threat Intelligence Report found more DDoS attacks in the first half of 2021 compared to the whole of 2020. This includes multi-vector DDoS attacks to amplify their efforts, with 31 vectors deployed in a single attack against one organization in 2021. On average, multi-vector attacks using 20-plus vectors spiked by 106%.

The sheer amount of bandwidth available at any attacker’s disposal means that organizations must now commonly defend against large-scale massive attacks. Since 2020, through various waves of DDoS extortion campaigns we’ve witnessed, this trend holds true. For instance, the initial wave of attacks averaged about 200 Gbps, but by the third wave, Akamai observed and mitigated attacks upward of 800 Gbps, and some have cleared 2 Tbps.

“Since the barrier-to-entry for threat actors is now lower than ever with easily accessible DDoS-for-hire services and IP stressers, compromised IoT devices can and will drive this growth,” said Charles Choe, Senior Product Marketing Manager at Akamai. “IoT devices coupled with the growth of edge computing endpoints that can be exploited alongside new amplification and reflection techniques will continue to drive larger and more sophisticated attacks.”

Key DDoS Protection Features

Core DDoS solution features include detection of the early stages of an attack, the scale to absorb the volume of traffic, and the ability to mitigate the source of the attack. This can be done via static or custom rules, or through an evolving set of defensive actions as the attack morphs toward additional targets.

A good DDoS protection solution should offer:

  • A service level agreement with a guaranteed time to mitigation (TTM)
  • Consistent application uptime and availability
  • Quality and accuracy of mitigation
  • Fast and simple on-boarding
  • Integrations with Terraform and other APIs

In addition, most DDoS mitigation solution providers bundle Web Application Firewall functionality to prevent DDoS attacks at the application layer. However, voice over IP (VoIP) and telecom-based DDoS campaigns are very much on the rise. As it is not a traditional web application, IT teams should verify that VoIP protection is included in their DDoS solution to effectively protect voice, communication, and collaboration applications.

Ribbon offers a suite of core Session Border Controllers with advanced DDoS detection and mitigation capabilities. It provides DDoS detection and mitigation through configuration and dynamic adaptation at scale, with little to no impact on traffic throughput or packet processing.

Key Differentiators

  • ACL policing applies access level control to allow traffic from trusted pre-configured IP addresses
  • IP address learning: When IP addresses used by valid peers/endpoints are not known prior or may change dynamically, peers are confirmed as trusted only after receipt of specific valid SIP requests
  • Media packet policing accepts media packets only if they correspond to a session negotiated via SIP/SDP signaling
  • Media address learning: If a peer media address advertised in SIP/SDP does not match the actual source address of the RTP packets, it is possible to learn the peer media address to perform policing of subsequent packets
  • Priority aware packet policing: rate limit SIP signaling packets on a microflow basis and give higher priority to packets from authenticated sources than those from unknown sources to increase the likelihood that desired traffic gets let through while malicious traffic is stopped
  • Application-level call admission control (CAC) to rate limit traffic on a peer/IP trunk/IP trunk group level and can also be provided to limit bandwidth usage
