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

"The solution is very good at mitigating threats."
"The API gives us the ability to remote control our DNS settings."
"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."
"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."
"Centralized, full-featured DNS."
"It is a fast and secure DNS."
"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."
"Cloudflare has many features."
"Due to the availability and power of these devices, we've been able to ramp off our upstream cloud-scrubbing provider and handle all attacks on our own."
"The solution's support is one of the coolest things about the product. I"
"It is a scalable solution."
"Thunder TPS has automated mitigation and fully managed support in case the device cannot handle the attack. They have engineers available to respond."
"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 solution has been rock solid for us; we haven't had any issues, we've had numerous attacks, and it's worked perfectly."
"I had a rather positive experience with A10 Networks Support Service."
"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."
"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."
"I like the fact that the product provides a hybrid solution."
"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 very efficient and robust appliance."
"This is a hybrid solution."
"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."
"The most important aspect, in general, is that the price is suitable for most clients."
 

Cons

"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"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."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"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."
"Cloudflare should add more documentation and pricing to the cloud version."
"There should at least be a read-only view of the data so that resellers can properly support the clients."
"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."
"It is very difficult to implement. It should be made a bit easier to implement."
"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."
"I would like for them to develop an advanced reporting feature."
"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 upgrade process for the boxes is not efficient. We have to go through the A10 aGalaxy where we have issues, like timeouts. They told me it was fixed in the latest version, but I tried to do it on the Portal and it is not working all the time."
"The upgrade process for the boxes is not efficient; we have to go through the A10 aGalaxy where we have issues, like timeouts."
"Its documentation could be better."
"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."
"Lacks international presence."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"The product must provide more Layer 7 capabilities."
"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."
 

Pricing and Cost Advice

"The price is reasonable."
"The price of the solution is expensive."
"The product's pricing is minimal compared to other products."
"We are using the free version."
"The product's pricing is cheap."
"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."
"A free version of the solution is available."
"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."
"Pricing is very reasonable."
"Pricing was much higher with Arbor (APS) for the same type of solution."
"We did a price survey, and compared to other solutions, A10 Thunder TPS wasn't cheap."
"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 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.""
"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."
"The tool is expensive. If one is low price and ten is expensive, I rate the tool's price as a ten."
"Its price is normal."
"The price of Corero is affordable."
