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.

Management console adds value and technical support delivers timely solutions
I had issues with the user interface because, when putting settings up, the system asked me for strange things like virtual local networks that I didn't create. For example, I set an NTP server, and after some clicks, a message appeared stating 'setup is incorrect'. It asked for a VLAN even though no VLANs were created. We had to find workarounds for issues like A10 blocking necessary traffic, sometimes leading to decreased security, because it was the simplest way to deal with them. This was a real issue. A more flexible policy for demo licenses would also be helpful.

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

"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."
"The overall performance of this solution is what makes it one of the best solutions on the market."
"This solution has improved the security of our organization."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"Using the CDN of Cloudflare improved the speed significantly, reducing the page loading times to appropriate levels."
"Based on previous equipment that we had, it's amazing that this device can do what it can do in a 1U form factor. The devices that we have right now have never gone over capacity and we've actually mitigated some pretty large attacks."
"The solution is easy to use and implement in terms of operations."
"We selected the solution because of its programmable automated defense using RESTful API. We didn't want to connect to the box. We wanted to be able to do some automation. We wanted to have our own portal because we wanted to connect our customers to our own UI using the A10 API. It has been good and exactly what we need."
"We were convinced that within a year, we'd definitely earn back the investment, both in the A10 equipment, as well as developing the end-to-end solution, including the integration with our administration systems."
"We can keep track of all the customer's requirements, we can forecast our trials, and we can forecast our overall financial things."
"The solution has been rock solid for us; we haven't had any issues, we've had numerous attacks, and it's worked perfectly."
"We selected the solution because of its programmable automated defense using RESTful API; we wanted to have our own portal and connect our customers to our own UI using the A10 API, and it has been good and exactly what we need."
"They give us the ability to configure many features for DDoS; there are many items that we can use."
"This is a hybrid solution."
"It is a good solution. Its vendor support is the most valuable. 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 a very efficient and robust appliance."
"I like the fact that the product provides a hybrid solution."
"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."
"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."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
 

Cons

"The product support needs to be accessible from more places, a wider area of coverage."
"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"Integration involving API with other products could be more user-friendly."
"Honestly the product has not really improved the way of my organisation."
"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"I would like for them to develop an advanced reporting feature."
"I rate Thunder TPS seven out of 10 for scalability."
"I would like for them to develop an advanced reporting feature."
"The solution is a little expensive."
"They have a cloud scrubbing feature that redirects the traffic if the on-prem appliance can't accommodate a large amount of traffic but it's not available where we are."
"If there's one aspect of A10 that needs improvement it would be the training. All of their training is done online, at least in what we've been exposed to. I would like to have a classroom environment for training... It would give [people] a chance to provision it."
"They have a cloud scrubbing feature that redirects the traffic if the on-prem appliance can't accommodate a large amount of traffic but it's not available where we are."
"It is very difficult to implement. It should be made a bit easier to implement. There is also a lack of resources on the internet. They need to develop more resources."
"Lacks international presence."
"The product must provide more Layer 7 capabilities."
"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."
"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."
"It could use support in Spanish."
"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

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"The product's pricing is cheap."
"There are no additional costs beyond the standard licensing fees."
"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."
"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."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"The price is reasonable."
"Pricing is very reasonable."
"The tool is expensive. If one is low price and ten is expensive, I rate the tool's price as a ten."
"We did a price survey, and compared to other solutions, A10 Thunder TPS wasn't cheap."
"We had a customer who was down for six hours and the loss of revenue for him was three times the price he was paying for us per year. The customer just said, "I don't care about paying you because on only one attack I saved money. It's three times better than losing money.""
"Pricing was much higher with Arbor (APS) for the same type of solution."
"The financials are always a challenge with this type of technology. That's not really a product-functionality thing but it's the area where we push A10 the most."
"We may need to pay fifty percent more if we purchase other solutions. For the payments made to A10 Thunder TPS, we have received three-year support."
"Its price is normal."
"The price of Corero is affordable."
