The Best DDoS Protection Services

Best DDoS Protection Services

Diego Asturias UPDATED: February 13, 2024

DDoS attacks are evolving— they are becoming more sophisticated and distributed. Now, they are starting to give real headaches to cyber-security experts.

Since the DDoS focus changed from network and transport layers (L3 and L4) to the application layer (L7), DDoS attacks are more challenging to mitigate. The volume of these attacks is also getting out of control. DDoS sources or bots are now distributed to every corner of the earth and into anything connected to the Internet. If something has IP, like cameras, NAS, servers, mobiles, or IoT devices, it can be turned into a bot and commanded to attack.

Here is our list of the best DDoS Protection Services

  5. Sucuri Website Firewall A cloud-based WAF with strong protection from DDoS attacks. It filters, and blocks suspicious DDoS traffic with intelligence and GeoIP detection.
  6. Cloudflare One of the largest CDN providers that offer protection against 3,4, and 7 layer DDoS attacks at a maximum capacity of 37 Tbps.
  7. Akamai Kona Site Defender A WAF built on top of Akamai Intelligent Edge Platform and designed to protect web assets from large DDoS attacks.
  8. CloudBric’s SWAP A fully-managed web security service with a cloud-based WAF based on artificial intelligence. The Cloudbric SWAP offers protection from Layer 3, 4, and 7 DDoS attacks

So, what can a DDOS protection service do to protect you from a DDoS attack?

  • Content Delivery Networks (CDNs) are a great defense against DDoS attacks because they redistribute traffic to edge servers. They eliminate the single point of failure by helping the victim (server) process traffic. CDNs can use DNS or Anycast technology.
  • Web Application Firewall (WAF) uses a set of rules, blacklists, or whitelists to filter traffic. Most WAFs use behavior-based rules to measure stress (DDoS attack) against a baseline of “ordinary traffic”.
  • DDoS protection mechanisms might also include rate limiting, a dashboard to manage traffic, threat intelligence databases, and managed services with support.

Other DDoS Protection Services Worth Mentioning

  • Link11. Leading IT security company with patented DDoS protection for websites and IT infrastructure. Link11 Web Security Suite includes DDoS protection for web, Bot management, Zero-touch WAF, threat intelligence, and Secure CDN.
  • AWS Shield. Amazon Web Services (AWS) Shield is DDoS protection managed service for applications running on AWS. An advantage of AWS Shield is that it is backed up by AWS’s CloudFront CDN and Route53 DNS service. AWS Shield provides protection for Layer3,4, and 7.
  • Imperva is a multi-cloud platform designed to protect apps, edge, and databases. Imperva offers a cloud-based DDoS protection service that includes 44+ DDoS scrubbing centers, protection from 6 Tbps, and protection from layers 3,4, and 7.


The best strategy against DDoS attacks is to prepare beforehand. A successful DDoS attack can damage an entire business’s revenue, reputation, and productivity. Waiting until you are under attack and then look for help, is not a good solution.

Although a DDoS protection service will not stop the attack— it will mitigate it. It will make it less hostile so that your server can still respond to legitimate traffic— until the DDoS attacker runs out of resources.

To protect your IT infrastructure, on-premises tools like SolarWinds Security Event Manager or Akamai Prolexic Routed will do a great job. For distributed web apps, use a combination of large CDNs with intelligent WAFs. Akamai and Cloudflare have the largest CDNs+WAF. But Sucuri WAF and IndusFace AppTrana have intelligent filtering systems.
