It's easy to set up because you point the DNS to it, and it's working in under 15 minutes

Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

A highly stable solution that can be used for load balancing

We contacted the solution's technical support to maintain and exchange the power supply. A few versions ago, we had some CPU and memory problems. We just started the appliance, and it was already on 70% of CPU usage. We first contacted our reseller in Brazil and then escalated the issue to A10 Thunder TPS support. The reseller in Brazil was a little slow, but the A10 Thunder TPS support was fast.

A solution requiring straightforward maintenance while remaining cost-effective compared to its competitors in the market

I am not in a position to speak about the areas where the solution needed improvement because I resigned during the implementation phase. At that time, the implementation was ongoing, and everything seemed to be going well. Using the solution, our team managed to transfer a couple of routers through a few areas. However, I believe the migration is still ongoing. Nonetheless, the first phase of the implementation was successful before my departure. There was a certain level of performance degradation in the solution, which I don't know if it can be tuned. This is because I was working for a short period on the solution. In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution. If one wants to scale up, then one needs to change their plan. However, the thing is, one can always go for the larger scale based on one's anticipation of future traffic.

Quotes from Members

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

Pros

"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."

"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."

"The solution provides good load balancing and protection against DDoS attacks."

"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."

"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."

"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."

"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."

"The technical support is good."

More Cloudflare pros

"The solution is easy to use and implement in terms of operations."

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

"Based on previous equipment that we had, it's amazing that this device can do what it can do in a 1U form factor. The devices that we have right now have never gone over capacity and we've actually mitigated some pretty large attacks."

"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 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 most valuable feature of A10 Thunder TPS is load balancing."

"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."

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

More A10 Thunder TPS pros

"The support team was helpful."

"The managed service allows us to confidently rely on Nexusguard’s professional team to take relevant actions as and when required to make sure DDoS attacks are successfully mitigated, ensuring 100% uptime of our service."

"Based on the support received for implementation, I rate the solution's technical support a nine out of ten."

"Cloud Diversion is another good feature packaged with the whole solution. When attack traffic is detected, Cloud Diversion triggers to automatically route our prefix to Nexusguard’s scrubbing center, ensuring that all attack traffic is dropped in the shortest time possible."

"Filters can be customized depending on the characteristics of the attack traffic. This feature has made it easier for Nexusguard's SOC team to further isolate any specific attack that can't be blocked by pre-configured mitigation."

Cons

"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."

"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."

"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."

"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."

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

"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."

"The pricing could be improved."

More Cloudflare cons

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

"Its documentation could be better."

"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."

"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."

"I rate Thunder TPS seven out of 10 for scalability."

"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. All of their training is done online, at least in what we've been exposed to. I would like to have a classroom environment for training... It would give [people] a chance to provision it."

More A10 Thunder TPS cons

"The solution must provide features for the post-processing of the traffic type and the traffic quality."

"One thing that we would like to improve from them is to provide more training to SOC team for them to have a deep understanding of the solution so that they would always be ready to answer anything without the need to escalate queries to senior personnel."

"One of the features that should be added to the next release is report generation. Currently, reports can be downloaded every month and are only available at the beginning of each month. It would be nice to generate the reports based on specific dates that we prefer and not have to wait until the next month for the current month’s report."

"There was a certain level of performance degradation in the solution, which I don't know if it can be tuned...In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution."

"The mitigation scope of Origin Protection is not fully efficient as there could be delays in activating the countermeasures."

Pricing and Cost Advice

"The product's pricing is cheap."

"So far I use free tier and happy with it. You can subscribe to business package if needed."

"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."

"The price is reasonable."

"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."

"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."

"The price of the solution is expensive."

More Cloudflare pricing and cost advice

"Pricing is very reasonable."

"We did a price survey, and compared to other solutions, A10 Thunder TPS wasn't cheap."

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

"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.""

"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 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."

"On a scale of one to ten, where one represents a cheap option, and ten represents an expensive option, I would rate the solution a seven in terms of cost."
