Users have experienced comprehensive protection against DDoS threats while enjoying seamless integration
The most valuable feature of Arbor DDoS is that it is based in most of the ISPs all over the world, and Egyptian ISPs are one of them. If a customer who is getting internet connectivity from one of the ISPs has an Arbor at the end, it will be integrated with the ISP Arbor. It's some sort of closing all the cycle with Arbor DDoS, from the ISP sides and from your side as a customer. Traffic analysis with Arbor DDoS is very good; it is brilliant. They act in a different way compared to others, and the vendor support is very good. The main benefits Arbor DDoS provides to users include stopping DDoS attacks, which is the biggest nightmare for all customers.

An easy-to-use tool with great GUI
The product's initial setup phase was really easy. There is a lot of time involved in the testing phase and other processes related to the area of deployment, so it may take up to two weeks to deploy the solution. The solution is deployed on an on-premises model. One person is enough to take care of the deployment phase of the product. The person involved in the deployment phase needs to better understand topologies when dealing with Fortinet.

Provide DDoS protection and better security at effective rate
It is expanding its number of data centers for scrubbing traffic. Currently, there is only one POP for cleaning in South Africa. They might add another POP in North Africa, possibly in Nigeria or Egypt. Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning. Increasing the number of POPs across the continent would help address these latency issues and improve overall service. While the platform is already quite strong, there’s always room for improvement, especially in keeping up with emerging trends and new types of attacks. Enhancing security capabilities could be beneficial. Integrating more advanced AI features could significantly improve its effectiveness and help customers leverage these tools more effectively. It would be great to see more focus on AI integration to handle and analyze data more efficiently.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We have taken on the Arbor Cloud subscription, which is really useful because you secure yourself for anything beyond your current mitigation capacity. This is a really good feature of Arbor that is available."

"Because this Arbor DDoS product is the best, I do not need to spend time supporting it."
"The quality of the technical support provided by Arbor DDoS is premium."
"The stability is okay and we have not encountered problems with the solution."
"Arbor DDoS is easy to use, provides effective blocking of DDoS attacks, and can be used for DNS, web, and main servers. Additionally, this solution is far easier to operate than others solutions, such as Fortinet DDoS."
"Packet inspection has been effective for mitigating DDoS attacks."
"The product allows the users to adjust the thresholds."
"It allows me to see all the traffic on my network."
"I find the interface easy to use."

"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The product's initial setup phase was really easy."
"The complete solution is valuable for everything it delivers and the protection it offers."
"Imperva DDoS helps us automate production. The client had specific requirements for a cloud project in the financial sector."
"Setup was straightforward, very simple. I only entered the domain and Incapsula returned the DNS data that I needed to change for the protection to be configured."
"Provides Anti-DDoS protection, as well as other protections like SQL injection, Cross-Site Scripting, and antiscanner. These types of protection are valuable to the business due to the daily attacks on our portals, and that often cannot be seen without a tool like this."
"Incapsula takes care of the CDN infrastructure and bandwidth volume, providing several enterprise "load balancing" features."
"The most valuable features for us are the DDoS and Bot."
"Its unique interface for managing security performance and ease of use are the most valuable features of this solution."
"They're quite easy to install and quite easy to set up. Clients really like that. Especially when you're dealing with the cloud, it's really easy."
 

Cons

"The solution's IT support needs improvement."
"They also have limited sizes of the boxes. Different sizes are needed because some customers are very small while others are very big, such as ISPs, so this categorization should be available."
"For troubleshooting problems, it's not so intuitive. It's not straightforward. This is the core of their kernel, so they need to improve it a little bit... In F5 I have full control of everything."
"We need a SaaS model for the solution."
"The following areas need improvement: opening and tracking support tickets, online support resources, software upgrades/updates and replacement media, and event management guidelines."
"The product could have end-to-end platform visibility."
"The prices for Arbor DDoS are expensive. The licensing is subscription-based."
"The solution could be more granular to include logs per second and enhanced pipeline monitoring for router licenses."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The web interface could be much better."
"The solution can be a little more user-friendly and it can be more affordable."
"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"We had an issue when securing the web applications for DDoS protection."
"Pricing can be improved, as it is quite expensive."
"I would like to see automated reporting to improve visibility."
"The solution needs to improve Integration with third parties for their on-prem deployment models. The integration is not that good yet."
"The salespeople tend to exaggerate its capabilities, which can cost you money if you don't verify the information."
"The rules surrounding the making of web applications could be improved."
"Imperva DDoS does not provide version control."
"I am not sure if this application has a policy where you can create your custom policy and run it as our firewall. We should have some ability to also create some custom policy, then run it as a firewall."
 

Pricing and Cost Advice

"The pricing of the solution is cheap."
"Because the solutions from competitors are very different, it's not easy to compare. However, the licensing from Arbor is clear and understandable and the pricing is reasonable when looking at the market, in general."
"As far as I know, they are the best in this sector, in DDoS protection. They know it, I know, because their service prices are too high. They provide cloud DDoS protection for ISPs, but that is also too expensive."
"I'm a technical guy. But I know it's expensive compared to its competitors. After you have the on-premise solution, for your solution to be effective you have to subscribe to an "upper level," so there's another cost. There is also a subscription to cloud services, which is another cost."
"The licensing of a complete Arbor solution, including fire-walling and unified site management, can get expensive."
"Pricing is slightly on the higher side."
"There is room for improvement with the pricing. It is an expensive solution. The issue with the pricing is more the way it is built. Right now we're paying per router, and there's a limitation there. I would like to see bundle-pricing where there is an overall solution cost."
"I believe that the price of Arbor DDoS falls under the bracket of medium to high price."
"It's quite pricey."
"The solution is reasonably priced."
"The product’s pricing needs improvement."
"There is a license or subscription renewal that our customers pay."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a five out of ten."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"Pricing could be more competitive."
