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.

Quotes from Members

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

Pros

"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."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"I have not had a DDOS attack since, or at least not become unavailable due to DDOS which means my ROI is pretty good."
"I like Cloudflare's application gateway and DDoS protection."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"If it was not for CloudFlare, I would have to hire a dedicated resource to manage all this for me."
"CloudFlare has positively improved my site's speed, performance and security."
"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."
"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."
"The solution is easy to use and implement in terms of operations."
"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 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."
"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."
"They give us the ability to configure many features for DDoS. There are many items that we can use."
"The product's initial setup phase was really easy."
"It is a user-friendly product in terms of monitoring and updating policies."
"The most valuable feature is the cloud DDoS scrubbing capability."
"We use it to protect our users and their data."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"We have researched them all, and it's a good solution all around."
"It allows me to see all the traffic on my network."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
 

Cons

"The solution could use more analytics on the backend to give us more insights into everything."
"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."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"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."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"CloudFlare doesn't provide the cache flush history. I am not able to find out the URL information of those I have recently flushed."
"The solution is a little expensive."
"Its documentation could be better."
"I rate Thunder TPS seven out of 10 for scalability."
"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 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."
"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."
"The web interface could be much better."
"The product’s pricing needs improvement."
"I would like to see analytics, big data."
"I would like to see analytics, big data."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"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 solution can be a little more user-friendly and it can be more affordable."
 

Pricing and Cost Advice

"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."
"I give the price a five out of ten."
"The cost primarily depends on the size of the organization."
"The product's pricing is minimal compared to other products."
"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."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"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 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 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."
"The solution is reasonably priced."
"It's quite pricey."
"The product’s pricing needs improvement."
