Distributed Denial of Service (DDoS) is a type of attack that involves using multiple compromised networks to target a single website. Hackers execute DDoS attacks by hijacking unprotected computers and installing malware. By using thousands of these "bots" or "zombie computers," hackers target a single web-based application or website, flooding it with a huge volume of traffic and causing the target to become unavailable to legitimate users.
Recently, DDoS protection has become increasingly difficult as DDoS attacks have now become sophisticated. DDoS attackers have moved their focus from the network and transport layers to the application layer, where DDoS protection is difficult to maintain. Exponential growth is seen in the size of attacks, and most enterprises lack the capital resources to scale their security programs to provide suitable DDoS protection.
Let’s look at the top 10 companies providing DDoS protection:
cWatch is a Managed Security Service for web applications and websites – which means they handle all the security measures on your behalf. As the most affordable on our list, it is available with a Web Application Firewall (WAF) provisioned over a Secure Content Delivery Network (CDN). If your website is affected by a DDoS attack, Comodo will know it even before you do. cWatch’s team of cyber experts monitor your website 24/7. Should an attack occur, Comodo’s Cyber Security Operation Center (CSOC) team leverages cyber technology and immediately acts to prevent the attack, while providing you with a detailed post-event forensic report. They leverage its WAF’s virtual patching and hardening engines to offer real-time threat mitigation without impacting your site. Their free plan offers lite DDoS protection using its complimentary CDN service.
2.Verisign DDoS Protection Services
When a DDoS attack is detected by Verisign, support personnel instantly notify customers about it and recommend an ideal mitigation strategy. Besides the monitoring feature, Verisign also offers on-demand mitigation. It comprises Open Hybrid API that allows organizations to use their existing security systems to send threat information to Verisign’s cloud-based service for possible mitigation.
3.Akamai DDoS mitigation
Akamai's DDoS mitigation solution includes CDN-based, DDoS scrubbing, and DNS components, based on each customer's requirements. Akamai mitigates DNS-based DDoS attacks, besides safeguarding DNS services from DDoS attacks.

This website security company offers its clients a choice of automatic "always on" DDoS mitigation vs. "on demand." Both offerings are a paid service, prices vary, and the "always on" solution, the company’s technology claims to handle "hit and run" DDoS attacks.
