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.

Information Technology Security Engineer at a tech services company with 11-50 employees

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

"It is a fast and secure DNS."

"The DDoS protection is the most valuable aspect of the solution."

"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."

"It's a reasonably priced solution that meets customers' needs and it's not too difficult to deploy."

"For businesses that don't have a dedicated security team, I think it's a better product; it's more intuitive for people like us."

"DDoS protection is this product’s most valuable feature."

"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."

"This solution has improved the security of our organization."

More Cloudflare pros

"The solution's support is one of the coolest things about the product. I"

"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 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 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."

"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."

"I had a rather positive experience with A10 Networks Support Service."

"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."

"They give us the ability to configure many features for DDoS. There are many items that we can use."

More A10 Thunder TPS pros

"We've been completely satisfied with the product."

"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."

"I find the interface easy to use."

"The product allows the users to adjust the thresholds."

"We use it to protect our users and their data."

"The product's initial setup phase was really easy."

"The pricing of this solution is better than that of Cisco and other software on the market, which are very expensive."

"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."

More Fortinet FortiDDoS pros

Cons

"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."

"I rate technical support quite badly."

"Cloudflare's console should be made more user-friendly."

"I would like to not need a separate server for non-www redirection under the CNAME setup option."

"At the end, it is worth than giving your house keys to the NSA."

"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."

"The solution could be more user-friendly."

"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."

More Cloudflare cons

"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."

"If there's one aspect of A10 that needs improvement it would be the training."

"We have had some issues with implementation. So, it is the only area that needs improvement."

"We currently do not use the solution's machine-learning-powered Zero-day Automated Protection because of an issue with it."

"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 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."

"The solution needs improvement in terms of fail-open."

More A10 Thunder TPS cons

"The initial setup is complex. It is always complex."

"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."

"Alerts and reporting features must be improved."

"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."

"Earlier versions of firmware had bugs that limit my options."

"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."

More Fortinet FortiDDoS cons

Pricing and Cost Advice

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"We are using the free version."

"The price is reasonable."

"The solution is expensive when compared to other products but offers unlimited bandwidth."

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."

"The product's pricing is minimal compared to other products."

More Cloudflare pricing and cost advice

"Pricing was much higher with Arbor (APS) for the same type of solution."

"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."

"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."

"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.""

"It's quite pricey."

"The solution is reasonably priced."

"The product’s pricing needs improvement."
