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.

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

"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"The technical support on offer is excellent; they are very helpful and responsive, and we are quite happy with the level of service they provide to their customers."
"I rate its stability a ten out of ten."
"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."
"The setup and configuration is also easy to perform and their support is excellent."
"This solution has improved the security of our organization."
"It's very user-friendly."
"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's support is one of the coolest things about the product. I"
"It is a scalable solution."
"We can keep track of all the customer's requirements. We can forecast our trails and we can forecast our overall financial things."
"The product's initial setup phase is very simple."
"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 most valuable feature of A10 Thunder TPS is load balancing."
"The solution is easy to use and implement in terms of operations."
"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."
"It is a very efficient and robust appliance."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"It is a good solution, its vendor support is the most valuable, and it is simple and works well if you have Juniper MX routers."
"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."
"This is a hybrid solution."
"The most important aspect, in general, is that the price is suitable for most clients."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
 

Cons

"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"DNS Management."
"Cloudflare should add more documentation and pricing to the cloud version."
"There should be a specific price list for enterprise-level customers."
"The product needs to improve its automation."
"The analytics, basically the dashboard, doesn't have much to it."
"Latencies are always a problem."
"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."
"I would like for them to develop an advanced reporting feature."
"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."
"It is very difficult to implement. It should be made a bit easier to implement."
"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."
"If there's one aspect of A10 that needs improvement it would be the training."
"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."
"I would like for them to develop an advanced reporting feature."
"Its documentation could be better."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"The product must provide more Layer 7 capabilities."
"Lacks international presence."
"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."
"It could use support in Spanish."
"It could use support in Spanish."
"Juniper is known in our country, but it is not very popular."
"I'd like to see an increase in Corero's international team. Our clients are generally companies with an international presence and Corero is not represented in all the countries where our clients have presence."
 

Pricing and Cost Advice

"We are using the free tier of the solution."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"The product's pricing is minimal compared to other products."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The product's pricing is cheap."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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 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."
"We did a price survey, and compared to other solutions, A10 Thunder TPS wasn't cheap."
"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."
"Its price is normal."
"The price of Corero is affordable."
