Reliable protection ensures robust network defense and simplifies DDoS management

I am not sure if we plan to use additional features because we have many vendors and platforms that we support. We use the main function and that is it. The prices for Arbor DDoS are expensive. The licensing is subscription-based. From our sales department, they discuss that prices are very high. A potential improvement could be establishing a contract with Cisco to sell via their channel. This could be beneficial because we work extensively with Cisco. If you are a Cisco partner, you can sell Arbor DDoS. That would be good for customers that are Cisco-based because many customers in Bosnia are Cisco-based customers. BH Telecom, our main customer, sells Arbor DDoS to other customers for protection. They buy Arbor and sell the product services to others via Internet links. They sell add-on DDoS protection via Arbor DDoS. In Bosnia and Herzegovina, Arbor DDoS is not present in many customers. Some customers try to sell it, but they sell other vendors such as F5. Arbor DDoS is mainly seen in telecom operators but not much in other customers.

Advanced protection has secured critical web workloads and provides clear traffic visibility

From a security perspective, there remains a security loophole, as some browsers in the market can bypass the Turnstile solution, which requires approximately 40 seconds to do so. From a performance perspective, this is acceptable. We also tried Google reCAPTCHA, and that can also be bypassed. From a security perspective, I would say neither solution is completely secured. Regarding uptime, we have faced a couple of incidents due to Cloudflare in recent years, so I cannot say we receive 100% uptime for our region. We sometimes face challenges, including downtime and other issues. As a result, we are not receiving 100% uptime from Cloudflare's solution. Since most of our customers are in this region, we need alternatives. We need something more competitive than Cloudflare. Unfortunately, in Bangladesh, Cloudflare has three points of presence already, and we cannot find any other solution provider in Bangladesh as an alternative, which presents another challenge. Competitor solutions have more attack signatures, which ensure better security compared to Cloudflare's predefined configurations. Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements. Cloudflare could improve in this area. Additionally, regarding visibility, Cloudflare has static visibility, but they could adopt dynamic graph features for their customers.

Effective network and DDoS protection with suitable pricing

I use Corero for network DDoS protection projects. It is particularly effective in providing protection against network DDoS attacks I find Corero to be good, especially in a wide area. It does not have application filtering or application DDoS prevention, but for network DDoS projects, it is…

Quotes from Members

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

Pros

"Arbor has the ability to learn and self-create the appropriate profile for each customer, ensuring that false positives are kept to a minimum."

"The artificial intelligence feature is most appreciated, as this solution can lower the throughput and clear the traffic, which is really important for us, and it also provides good protection."

"The auto-mitigation, that signaling feature, where it automatically raises an alarm that a line is under attack, is important. The upstream service provider will then do something to reduce the load on our internet lines. The fact that it's automated means I don't have to sit and always be looking at threats coming through. It does it almost automatically, without any intervention by me."

"The solution provides good protection against volumetric DDoS attacks."

"With real-time packet capture features, you can easily and quickly response."

"It prevents all unwanted or malicious traffic, using the Threat Intelligence feeds."

"It's an excellent product DDoS protection against attacks."

"It improves our organization by preventing attacks and improving the availability of the network on services, which provides a better service to customers."

More Arbor DDoS pros

"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."

"There are key things that are used for our enterprise customers, such as Lambda and DNS."

"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."

"Another reason it's awesome is that you don't need your server to handle every request."

"CloudFlare's caching brings the load speed down from 4.32 seconds to 2.45 seconds."

"The solution is stable, and the DNS servers are simple to use."

"The API gives us the ability to remote control our DNS settings."

"Their free account offers an awful lot of functionality and savings alone, before you get on to the minimal $20 a month for a Pro account which comes with its own great list of features."

More Cloudflare pros

"It is a very efficient and robust appliance."

"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."

"I like the fact that the product provides a hybrid solution."

"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."

"It is a good solution, its vendor support is the most valuable, and it is simple and works well if you have Juniper MX routers."

"The most important aspect, in general, is that the price is suitable for most clients."

"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."

"This is a hybrid solution."

More Corero pros

Cons

"A small improvement could be a better reporting system."

"It could include a lot of enhancements related to AI and automation."

"Support in Argentina is not so good. Although the team is good, they are not fast, and they lack the skills to manage dynamic attackers."

"Auto mitigation is a feature provided when DDoS is observed on any of link/customer (configured under auto mitigation). It automatically starts mitigation with default filters. In default filter mode, there could be an impact on the customer’s link,"

"The support got worse after NETSCOUT acquired Arbor."

"In the default filter mode, there could be an impact on a customer’s link."

"When it comes to some false positives, we need to tweak the system from time to time."

"An improvement would be to provide information on how pricing is done on different customer levels (e.g. is it done per gig or bandwidth?)."

More Arbor DDoS cons

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."

"The product support needs to be accessible from more places, a wider area of coverage."

"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."

"The product needs to improve its automation."

"The integration of LLMs on the dashboard is something that is needed in the tool."

"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."

"The Always Online feature has room for improvement. It seems to work sometimes and not others even with the pro version."

More Cloudflare cons

"Lacks international presence."

"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."

"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."

"It could use support in Spanish."

"Juniper is known in our country, but it is not very popular."

"It could use support in Spanish."

"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."

"The product must provide more Layer 7 capabilities."

More Corero cons

Pricing and Cost Advice

"I don't deal with the pricing, but it seems that you need to get basic support in order to upgrade the software and implement some patches."

"The pricing of the solution is cheap."

"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."

"Arbor's products are very expensive. Their competitors are cheap when compared with Arbor."

"The solution's pricing is based on a licensing model that is expensive when compared to other tools."

"Arbor is striking a good balance between pricing and what they deliver."

"Pricing is slightly on the higher side."

"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."

More Arbor DDoS pricing and cost advice

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."

"I give the price a five out of ten."

"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."

"The product's pricing is cheap."

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."

"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."

"The tool is a premium product, so it is very expensive."

More Cloudflare pricing and cost advice

"The price of Corero is affordable."

"Its price is normal."
