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.

Automated threat intelligence and flow-based mitigation have improved our DDoS defense

A very useful feature in Arbor DDoS is its ability to send flow spec announcements to routers. For example, if it is clear that a Layer 3 or Layer 4 attack is occurring and the attack pattern is identified through source and destination IP addresses and ports, you can generate flow spec filters. These filters are transferred through BGP to border routers, which automatically build filters, mitigating the attack even at the network's boundary and preventing it from reaching the TMS. This allows the TMS to focus on other tasks. This is a highly effective feature that can mitigate huge volumetric attacks; for example, we experienced a 32-gigabit attack, and all those 32 gigabits were dropped by our border routers, not by Arbor DDoS itself. The flow spec announcement was generated by Arbor DDoS, and as far as I know, the same technology is used by Radware, but it comes under a different feature and a different license. At the time, we were told that flow spec mitigation was an additional very expensive license to purchase from Radware, while Radware included everything in one package.

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

"Stability is great; I love their mechanisms, I love their GUI, I love their front end, I love their behind the scenes, algorithms and everything, it all makes sense."

"Cloudflare has made management of my website much easier by combining various functions in one platform without compromising quality."

"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."

"The solution offers the flexibility to control configuration rules."

"It is a fast and secure DNS."

"Cloudflare has many features."

"Cloudflare's DNS services deliver the best performance in terms of speed and reliability."

"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."

More Cloudflare pros

"We use almost all the features of Arbor DDoS, but it really depends on the customer’s requirements, so I can’t specify exactly which features we use. However, many customers appreciate the basic DDoS protection, especially those without specific protection needs. For example, financial companies benefit from the cloud DDoS protection. It’s a straightforward solution that effectively meets their needs."

"We found what we wanted in Arbor DDoS; it met our expectations as IT users of different types of complex environments and fit our needs."

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

"We can reduce the bandwidth to minimize the attack level. If we see more than 2.5 GBs we drop it directly."

"With Arbor, when we see DDoS attacks, it is fully mitigating the attacks."

"Arbor DDoS's best feature is that we can put the certificates in, and it will look at layer seven and the encrypted traffic and do the required signaling."

"In terms of Arbor DDoS's reporting and analytics, Arbor DDoS is superior to Radware, especially when comparing it to the Radware model which I used previously."

"I like all the features together as a whole."

More Arbor DDoS pros

"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."

"The DDoS protection features are valuable."

"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."

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

"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."

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

"This is a hybrid solution."

More Corero pros

Cons

"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."

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

"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."

"Access to the solution's dashboards is not intended for a service company. You are practically blind, and to validate a problem, you must view the customer's screen."

"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."

"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."

"Honestly the product has not really improved the way of my organisation."

More Cloudflare cons

"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."

"Arbor DDoS could improve out-of-the-box reporting, it could be better."

"The regional support here in African could improve, such as marketing and account managers."

"If we want to see live traffic, we can see do so. But once an attack that lasts for five minutes is done, the data is no longer there. It would be an improvement if we could see recent traffic in the dashboard. We can check and download live traffic, but a past attack, with all the details, such as why it happened and how to mitigate and prevent such future attacks, would be helpful to see."

"On the main page there are alerts that we are unable to clear, even though the issue has been resolved."

"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, e.g., if we have enabled monitoring of internal traffic for that link/customer, it starts mitigation on legitimate traffic."

"Because we had some routers that were somewhat old, they were not integrated with Arbor. They did not support the NetFlow version that Arbor was running. That was a challenge. We had to upgrade the routers. Some backward-compatibility would be helpful."

"On the application layer, they could have a better distributed traffic flow. They could improve that a bit. For network data it is very effective, but the application layer can be improved."

More Arbor DDoS cons

"It could use support in Spanish."

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

"Lacks international presence."

"The product must provide more Layer 7 capabilities."

"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."

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

"I'd like to see an increase in Corero's international team. Our clients are generally companies with an international presence and Corero is not represented in all the countries where our clients have 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."

Pricing and Cost Advice

"We are using the free version."

"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."

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

"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."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"The price of the solution is expensive."

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

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

More Cloudflare pricing and cost advice

"It is an expensive product. I use this product for its different features."

"I don't know about the pricing details as our company's service provider offers us the solution as an inbuilt feature within the internet bandwidth they provide us."

"We do not use the Arbor Cloud DDoS solution because it is too costly."

"I believe that the price of Arbor DDoS falls under the bracket of medium to high price."

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

"The price is a little high."

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

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

More Arbor DDoS pricing and cost advice

"The price of Corero is affordable."

"Its price is normal."
