Anti DDoS: Top Anti Website DDoS  Services Now

WAF is the best solution to combat today's Website DDoS attacks. So what is the popular WAF service trusted by many businesses?

What is WAF?

WAF (Web Application Firewall) aka Web Application Firewall helps to handle HTTP protocols to protect Web applications. WAF acts as the first line of defense, analyzing all the information data before it reaches the application or the end user.

There are three common types of web application firewalls:

  1. Hardware-based web application firewall
  2. Software-based web application firewall
  3. Cloud-based Web Application Firewall (Cloud WAF)

How WAF helps fight DDoS?

DDoS attacks are of two main types. And the article will learn about the protection methods that should be used in each case:

1. DDoS attack by volume: Massive DDoS attacks are designed to overwhelm internet pipelines and regardless of what defense you have on your Internet Edge (like DDoS Appliance, FW, WAF, IPS...) The only effective solution to prevent bulk DDoS attacks is to use an anti-DDoS service with a Cloud WAF (Web Application Firewall) firewall combined with a Multi CDN (Content Delivery Network).

2. Massive DDoS attack: This second type of DDoS attack doesn't overwhelm a business's internet pipeline, but is just as capable of destroying website or application availability as a volume-based DDoS attack.

Enterprises can equip a secure layer of defense with a smart Cloud WAF firewall that can block spoofed IP addresses, ports other than http, etc. At the same time, WAF also provides multiple levels of protection. Websites and applications are safe from DDoS attacks such as:

  • PPS detection threshold
