8 Best DDoS Protection Services

Best DDoS Protection Services

Diego Asturias

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.

In this post, we’ll review the best 8 DDoS protection services— plus three more worth mentioning. All these services include all or most of those qualities that will reduce the impact of a DDoS attack.

  1. Indusface AppTrana – FREE TRIAL A fully managed application security solution, including cloud-based WAF, DDoS intelligent protection, Bot control, and CDN to stop DDoS attacks. Start a a 14-day free trial.
  2. SolarWinds Security Event Manager – FREE TRIAL A SIEM solution that uses a multi-layer approach to monitor event logs from many sources, and detect and prevent DDoS activities.
  3. Akamai Prolexic Routed It uses Akamai’s massive CDN with scrubbing centers to identify and stop DDoS attacks in the cloud before they reach your assets.
  4. 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.
  5. StackPath Web Application Firewall A cloud-based WAF with emphasis on its edge locations and various techniques to detect and mitigate incoming DDoS attacks.
  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.

Once identified, it relocates resources to the single victim (via CDN) and uses ML models to allow legitimate traffic to go through.

The service may take up to 65 Tbps of junk traffic before hitting your server. This uncommon level of capacity should be enough to stop some of the largest DDoS ever recorded.

Pros:

  • Leverages behavioral machine learning to detect new forms of DDoS attacks

  • 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.

Conclusion

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.
