Top 12 Cloud-based DDoS Protection for Small to Enterprise Website

Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Don’t let the DDoS attack interrupt your business operation for reputational and financial loss. Use cloud-based denial of service protection to prevent getting hacked.

Anyone with bad intentions can hire a hacking service for a targeted attack. Malware tools are accessible, easy to use, and effective. Not just large companies, but cybercriminals are looking for any size vulnerable victims, including personal blogs, e-commerce shops, small to medium businesses.

One type of attack is particularly dangerous and increasingly common. It is called distributed denial of service attack, or DDoS for short. In a DDoS attack, a set of compromised, distributed systems –could be servers, home computers, Internet-of-Things devices, anything connected to the internet– is used to overwhelm a targeted system with a flood of requests, to the point in which the attacked system gets saturated enough to refuse to work.


Since the flood comes from many scattered sources, it is difficult to identify the attacker or to mitigate the attack. DDoS attacks are unpredictable, and some of the latest attacks are ridiculously dangerous. It was in a range of 800 to 900 Gbps.

Attackers can use many techniques to DDoS your online business. Some of the popular ones are the following.

  • UDP fragment
  • DNS, NTP, UDP, SYN, SSPD, ACK flood
  • CharGEN attack
  • TCP anomaly

The reasons for an attack could be many. First of all, the victims are hand-picked; they are never chosen at random. Maybe a competitor wants to kick you out of business, or maybe someone profoundly dislikes the content you publish –any excuse could be sufficient for someone to invest a couple of hundreds of dollars to attack your site.

You can take a look at cyber attacks in real-time.

How to prevent DDoS attacks?

If you own a small business with an equally small website, or you run a blog or a personal website, then you need to do something to avoid being a victim of a DDoS attack.

One option is to hire an MSSP (Managed Security Service Provider) to take care of all possible cyber threats. This includes intrusion detection, vulnerability scanning, anti-viral services, and provision of firewall and VPN technologies, among other services. A good MSSP will give you peace of mind, but probably at a high cost. In case you have most of the security bases covered and you only need to protect your site from DDoS, you can hire DDoS Protection as a Service (DPaaS) from your ISP or your hosting provider.

If you prefer a more DIY-ish solution, the first thing to implement is the detection and mitigation of DDoS. To detect a DDoS attack, you need to monitor incoming traffic to your website and look for any pattern that could imply an attack in the process. A sudden surge in traffic could be a signal, but you need to determine if the surge is a spike in legitimate user traffic or if it is the symptom of a DDoS attack, and that is not always an easy task.

Once you detect a true DDoS attack, you can identify the IP addresses sending the illegitimate traffic and block them with the help of your hosting provider or a traffic-filtering device, such as a router or a firewall. It sounds easy, right?

Well, if you take into account that a typical DDoS attack involves many millions of data packets per second, you can conclude that the DIY option is not viable, and you should hire an affordable cloud-based DDoS protection service.

How do DDoS protection services work?

An effective anti-DDoS solution must take care of the following tasks: detection, diversion, filtering, and analysis.

Detection means identifying traffic flow deviations that could be foretelling a DDoS assault. An effective anti-DDoS solution should be able to recognize the attack as soon as possible, avoiding false positives.

Diversion means to reroute the traffic away, either to discard it or to be filtered. By filtering, we mean to weed the DDoS traffic out, identifying it as malicious. An effective anti-DDoS solution will do this without affecting the experience of your legitimate users.

Finally, analysis is the review of traffic logs to gather information about attacks, both to identify the attacker and to enhance future detection activities.

When you need to compare anti-DDoS solutions, network capacity is an important factor to take into account. It is measured in Gbps (gigabits per second) or Tbps (terabits per second) and indicates how much attack intensity the protection can withstand. The cloud-based solution generally offers a network capacity of the order of terabits per second. This is much more than any website may require.

Other important measures of service level are forwarding rates and time to mitigation. The forwarding rate represents the capacity of the solution to process data packets and is measured in millions of packets per second (Mpps). Attacks commonly reach 300-500 Gbps, and some could scale up to 1 Tbps. The anti-DDoS solution processing capacity needs to top that in order to be effective.

Time to mitigation varies according to the method that the solution provider employs to detect an attack. An always-on solution with preemptive detection should be able to offer almost instantaneous mitigation. But this aspect needs to be tested in the field under real-life conditions.

Obviously, all these considerations must be weighed against the cost. Let’s take a look at some of the best cloud-based DDoS detection and protection solutions available.


Kona DDoS Defender is the name of the cloud-based solution Akamai offers to stop the threat of a DDoS attack. It combines the uninterrupted service of a Security Operations Center (SOC) with Akamai’s Intelligent Platform, which offers high scalability and guarantees the continuous operation of the website, even in the event of an attack.


Akamai’s Intelligent Platform is distributed worldwide, providing the ability to handle between 15% and 30% of the total global web traffic. It offers the necessary scalability to face even the biggest DDoS attack. When an attack occurs, Kona DDoS Defender automatically deflects SYN or UDP floods and absorbs HTTP GET and POST floods at the perimeter of the network, preventing them from reaching the core applications.

Final Words 👨‍🏫

If all the houses in your neighborhood have alarms, then yours should also have one, or it would be the preferred target for burglars. The same applies to your website or web application: you don’t want it to be one of the few without DDoS protection, or it may soon be attacked. A solution against DDoS is a reasonable and necessary investment if you want your online business to stay alive and kicking for a long time.
