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.

Monitoring capabilities improve threat detection and customer satisfaction
I am looking for a UTM for my customers as I am from a system integrator company Packet inspection has been effective for mitigating DDoS attacks. Real-time attack monitoring is integrated under FortiManager, so we do not always monitor the dashboard. Customers have not experienced issues and…

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 stable, and the DNS servers are simple to use."
"Using the CDN of Cloudflare improved the speed significantly, reducing the page loading times to appropriate levels."
"The solution is very good at mitigating threats."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."
"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"The most valuable feature of A10 Thunder TPS is load balancing."
"They give us the ability to configure many features for DDoS. There are many items that we can use."
"The solution is easy to use and implement in terms of operations."
"The solution's support is one of the coolest things about the product. I"
"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 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 response time to an attack is instant. We've used some outsourced solutions in the past, out in the cloud, that weren't so quick. But it's all within our control now. We control how fast it mitigates."
"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 use it to protect our users and their data."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"The protection resources and the support are valuable features of the solution."
"I find the interface easy to use."
"We have researched them all, and it's a good solution all around."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
"The equipment works very well, and I have not encountered any issues with it."
 

Cons

"The product support needs to be accessible from more places, a wider area of coverage."
"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."
"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"Support response time could be improved."
"Integration involving API with other products could be more user-friendly."
"Perhaps I would ask that they improve the Free plan and allow us to use it with any TLD (certain ones are not allowed)."
"The analytics, basically the dashboard, doesn't have much to it."
"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."
"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."
"I would like for them to develop an advanced reporting feature."
"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 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."
"Its documentation could be better."
"The solution is a little expensive."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The product’s pricing needs improvement."
"I would like to see analytics, big data."
"Alerts and reporting features must be improved."
"Earlier versions of firmware had bugs that limit my options."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"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."
"The web interface could be much better."
 

Pricing and Cost Advice

"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 price of the solution is expensive."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"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."
"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."
"We are using the free version."
"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."
"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."
"Pricing was much higher with Arbor (APS) for the same type of solution."
"The tool is expensive. If one is low price and ten is expensive, I rate the tool's price as a ten."
"Pricing is very reasonable."
"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.""
"It's quite pricey."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
