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

"Easier http to https redirect using page rules"
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The aggressive caching and DDOS mitigation are the most valuable features offered by Cloudflare."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"The tool is user-friendly."
"Cloudflare is easier to manage than the solutions provided by these vendors, and the user experience is much more straightforward and appeals to a lot of developers."
"The initial setup is extremely easy but will require access to your Domain Name Servers."
"The GUI is very use-friendly, you can configure it through CLI or GUI so they give you an option to choose, and it's a good solution in terms of the appliance itself because it's very light compared to other brands that offer DDoS solutions."
"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 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."
"The primary benefit that we see from their systems is that their filtering technology has the ability to detect and drop the malicious traffic from the legitimate traffic with a high success rate. That, in combination with the very small effort needed to manage their systems, are the two most important benefits to us."
"The product's initial setup phase is very simple."
"The solution's support is one of the coolest things about the product. I"
"The most valuable feature of A10 Thunder TPS is load balancing."
"The GUI is very use-friendly. You can configure it through CLI or GUI, they give you an option to choose. It's a good solution in terms of the appliance itself. It's very light compared to other brands that offer DDoS solutions."
"The DDoS protection features are valuable."
"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."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"I like the fact that the product provides a hybrid solution."
"The most important aspect, in general, is that the price is suitable for most clients."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"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 very efficient and robust appliance."
 

Cons

"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"Support response time could be improved."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"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."
"The analytics, basically the dashboard, doesn't have much to it."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"An integrated SSO feature would be useful for Cloudflare DNS."
"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."
"The solution needs improvement in terms of fail-open."
"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."
"We have had some issues with implementation. So, it is the only area that needs improvement."
"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."
"We currently do not use the solution's machine-learning-powered Zero-day Automated Protection because of an issue with it... We also use the aGalaxy platform, which is a management platform for the TPS devices. The issue is that some TPS features were added at the TPS level but weren't carried over to aGalaxy, and we manage all of our devices through aGalaxy. So we can't actually use some of the new features that are available on the TPS because that functionality doesn't exist in aGalaxy. That is one of my biggest complaints."
"The problem here is when you buy another box from A10, they want to put Thunder TPS to run, and it works okay, after which we cannot block it for another solution to be used, which is a problem for me where improvements are needed."
"I rate Thunder TPS seven out of 10 for scalability."
"The product must provide more Layer 7 capabilities."
"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."
"It could use support in Spanish."
"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."
"Lacks international presence."
"Juniper is known in our country, but it is not very popular."
"It could use support in Spanish."
 

Pricing and Cost Advice

"The price of the solution is expensive."
"The tool is a premium product, so it is very expensive."
"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."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The product's pricing is minimal compared to other products."
"That is one of the great features. I was able to access the majority of the features and services for free."
"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 pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"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."
"We did a price survey, and compared to other solutions, A10 Thunder TPS wasn't cheap."
"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."
"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 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 price of Corero is affordable."
"Its price is normal."
