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.

Reliable protection and smooth setup enhance company security
Currently, I have two firewalls, with one located in Sorocaba, model 90D, and the other in São Paulo, model 30D. They are connected by VPN. I use the firewalls for VPN and final protection for my company, and my equipment is maintained by an internet company called Multiprox The equipment works…

Quotes from Members

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

Pros

"It's a reasonably priced solution that meets customers' needs and it's not too difficult to deploy."
"Cloudflare improves performance on my websites and is a great partner for cloud infrastructure for anyone who wants to use the security service and other features."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"Easier http to https redirect using page rules"
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"The initial setup is extremely easy but will require access to your Domain Name Servers."
"The most valuable features of the solution are performance and security."
"The solution has been rock solid for us; we haven't had any issues, we've had numerous attacks, and it's worked perfectly."
"The most valuable feature of A10 Thunder TPS is load balancing."
"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."
"It is a scalable solution."
"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."
"The solution's support is one of the coolest things about the product. I"
"They give us the ability to configure many features for DDoS. There are many items that we can use."
"The solution has reduced the amount of manual intervention required during an attack. We have the inline solution and when it comes to the customers that we have on it, it has saved us some troubleshooting time."
"The protection resources and the support are valuable features of the solution."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"The product allows the users to adjust the thresholds."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The product's initial setup phase was really easy."
"The solution is very user-friendly and very easy to use."
"We've been completely satisfied with the product."
"It allows me to see all the traffic on my network."
 

Cons

"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."
"The pricing, setup cost, and licensing for Cloudflare are a bit on the higher side overall."
"The analytics, basically the dashboard, doesn't have much to it."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"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."
"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."
"Technical support is lacking."
"At the end, it is worth than giving your house keys to the NSA."
"I rate Thunder TPS seven out of 10 for scalability."
"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 solution needs improvement in terms of fail-open."
"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."
"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 solution is a little expensive."
"If there's one aspect of A10 that needs improvement it would be the training."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The web interface could be much better."
"The product’s pricing needs improvement."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
 

Pricing and Cost Advice

"There are no additional costs beyond the standard licensing fees."
"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."
"The cost primarily depends on the size of the organization."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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 minimal compared to other products."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"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."
"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."
"Pricing is very reasonable."
"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 product’s pricing needs improvement."
"The solution is reasonably priced."
"It's quite pricey."
