Has helped manage client domains with streamlined access control and threat visibility

I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. 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. It doesn't pay to try to host your own website.

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.

Effective network and DDoS protection with suitable pricing

I use Corero for network DDoS protection projects. It is particularly effective in providing protection against network DDoS attacks I find Corero to be good, especially in a wide area. It does not have application filtering or application DDoS prevention, but for network DDoS projects, it is…

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 of Cloudflare DNS is its global reach and it is always evolving."

"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 solution is stable, and the DNS servers are simple to use."

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

"Cloudflare consolidates various capabilities into one product, streamlining processes."

"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."

"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."

"Easier http to https redirect using page rules"

More Cloudflare pros

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

"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."

"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 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 product's initial setup phase is very simple."

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

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

More A10 Thunder TPS pros

"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."

"The most important aspect, in general, is that the price is suitable for most clients."

"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."

"The DDoS protection features are valuable."

"This is a hybrid solution."

"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."

"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."

Cons

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."

"The solution could work at being less expensive. It costs a lot to use it."

"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."

"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."

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

"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."

"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."

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."

"The upgrade process for the boxes is not efficient. We have to go through the A10 aGalaxy where we have issues, like timeouts. They told me it was fixed in the latest version, but I tried to do it on the Portal and it is not working all the time."

"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."

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

"Its documentation could be better."

"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 would like for them to develop an advanced reporting feature."

"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."

More A10 Thunder TPS cons

"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."

"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."

"It could use support in Spanish."

"The product must provide more Layer 7 capabilities."

"Lacks international presence."

"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."

Pricing and Cost Advice

"A free version of the solution is available."

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

"We don't have any issues with the price."

"There are no additional costs beyond the standard licensing fees."

"The tool is a premium product, so it is very expensive."

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

"We are using the free version."

"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."

More Cloudflare pricing and cost advice

"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 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."

"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."

"Pricing is very reasonable."

"The price of Corero is affordable."

"Its price is normal."
