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

"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"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."
"I rate its stability a ten out of ten."
"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."
"Easier http to https redirect using page rules"
"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."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"I had a rather positive experience with A10 Networks Support Service."
"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."
"Thunder TPS has automated mitigation and fully managed support in case the device cannot handle the attack. They have engineers available to respond."
"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."
"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 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 can keep track of all the customer's requirements, we can forecast our trials, and we can forecast our overall financial things."
"It is a scalable solution."
"The most valuable feature is the cloud DDoS scrubbing capability."
"Packet inspection has been effective for mitigating DDoS attacks."
"It allows me to see all the traffic on my network."
"The product's initial setup phase was really easy."
"We have researched them all, and it's a good solution all around."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The product allows the users to adjust the thresholds."
 

Cons

"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."
"However, what I still fail to understand is that why aren't they offering domains themselves."
"There are some issues with the CDN services."
"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."
"I have found CloudFlare's support to be unresponsive at times, and not very helpful with providing technical details for issues that we have reported over the years."
"I rate technical support quite badly."
"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"The Always Online feature has room for improvement. It seems to work sometimes and not others even with the pro version."
"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."
"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 have had some issues with implementation. So, it is the only area that needs improvement."
"I would like for them to develop an advanced reporting feature."
"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 solution is a little expensive."
"The last issue we had to contact them about was just a question of a false-positive. The A10 system wasn't supposed to decide what is a false-positive. So if we send it good traffic, it's supposed to just pass that good traffic through. But we opened this last ticket because the A10 did block some of the good traffic. Their support had to tweak it a little bit, but it wasn't anything that took a long time."
"If there's one aspect of A10 that needs improvement it would be the training."
"Earlier versions of firmware had bugs that limit my options."
"Alerts and reporting features must be improved."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"I would like to see analytics, big data."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
 

Pricing and Cost Advice

"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."
"A free version of the solution is available."
"The price of the solution is expensive."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The price is reasonable."
"The tool is a premium product, so it is very expensive."
"We are using the free tier of the solution."
"The product's pricing is minimal compared to other products."
"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."
"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."
"The tool is expensive. If one is low price and ten is expensive, I rate the tool's price as a ten."
"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.""
"It's quite pricey."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
