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

"The most valuable feature is the web application firewall."
"Easier http to https redirect using page rules"
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"Another reason it's awesome is that you don't need your server to handle every request."
"The initial setup is extremely easy but will require access to your Domain Name Servers."
"Cloudflare has many features."
"I rate its stability a ten out of ten."
"From a technical point of view, Cloudflare is the best CDN."
"It is a scalable solution."
"The solution is easy to use and implement in terms of operations."
"Availability is absolutely critical to our business; we get attacked two and three times a day at times, and although the attacks happen every day, they're not a big deal anymore because the mitigation takes care of it."
"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."
"We can keep track of all the customer's requirements, we can forecast our trials, and we can forecast our overall financial things."
"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 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."
"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."
"I find this product the best on-premises (in-line) DDoS mitigation solution that suits my current and future requirements."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
"The most valuable feature is the cloud DDoS scrubbing capability."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"Packet inspection has been effective for mitigating DDoS attacks."
"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."
 

Cons

"I rate technical support quite badly."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"The analytics, basically the dashboard, doesn't have much to it."
"The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service."
"However, what I still fail to understand is that why aren't they offering domains themselves."
"More insight into analytics and threats would be a good place to start improving Cloudflare."
"There might be helpful if there was some web application firewall feature."
"The installation was complex until I learned what I had to learn."
"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."
"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."
"If there's one aspect of A10 that needs improvement it would be the training."
"Its documentation could be better."
"The solution is a little expensive."
"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."
"We currently do not use the solution's machine-learning-powered Zero-day Automated Protection because of an issue with it."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"I would like to see analytics, big data."
"Earlier versions of firmware had bugs that limit my options."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
 

Pricing and Cost Advice

"We are using the free tier of the solution."
"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."
"That is one of the great features. I was able to access the majority of the features and services for free."
"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."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"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."
"There are no additional costs beyond the standard licensing fees."
"The price of the solution is expensive."
"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.""
"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."
"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."
"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 is very reasonable."
"The solution is reasonably priced."
"It's quite pricey."
"The product’s pricing needs improvement."
