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.

Edge caching has transformed response times and delivers faster candidate data globally
Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users. A more user-friendly, UI-based configuration could simplify the experience, alongside better templates for common use cases and dashboard improvements, as the current dashboard feels complex for beginners, and pricing can be hard to predict for smaller companies. I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities. However, VCL complexity and pricing predictability, especially for smaller companies, along with a user-friendly dashboard are areas impacting my score.

Quotes from Members

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

Pros

"If it was not for CloudFlare, I would have to hire a dedicated resource to manage all this for me."
"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."
"The overall performance of this solution is what makes it one of the best solutions on the market."
"The solution is stable, and the DNS servers are simple to use."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"Because our website is blazing fast it improves our conversion rates."
"Generally, I am satisfied with this product."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"We selected the solution because of its programmable automated defense using RESTful API; we wanted to have our own portal and connect our customers to our own UI using the A10 API, and it has been good and exactly what we need."
"They give us the ability to configure many features for DDoS. There are many items that we can use."
"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."
"The solution's support is one of the coolest things about the product. I"
"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."
"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."
"We selected the solution because of its programmable automated defense using RESTful API. We didn't want to connect to the box. We wanted to be able to do some automation. We wanted to have our own portal because we wanted to connect our customers to our own UI using the A10 API. It has been good and exactly what we need."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"Rate limiting is a good feature that protects from volumetric attacks."
"In summary, this solution is easy to manage, quick to deploy, and all of my customers are happy."
"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
"The product's initial setup phase is straightforward."
"Initially, we faced load time issues, but after deploying Fastly and optimizing our queries, we achieved a response time cut to less than 1 millisecond from an initial 3 to 4 seconds."
"Its initial setup process is straightforward."
"Fastly combines both the CDN side and the Signal Sciences next-generation WAF, which is closely integrated with the CDN, allowing us to use both products seamlessly."
 

Cons

"Perhaps I would ask that they improve the Free plan and allow us to use it with any TLD (certain ones are not allowed)."
"There are some issues with the CDN services."
"Access to the solution's dashboards is not intended for a service company. You are practically blind, and to validate a problem, you must view the customer's screen."
"The product support needs to be accessible from more places, a wider area of coverage."
"With CDN loads, sometimes we get an error that the host server is unavailable when the connection between CloudFlare and the server timed out."
"Latencies are always a problem."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"I would like to not need a separate server for non-www redirection under the CNAME setup option."
"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."
"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."
"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."
"I would like for them to develop an advanced reporting feature."
"We currently do not use the solution's machine-learning-powered Zero-day Automated Protection because of an issue with it."
"The solution needs improvement in terms of fail-open."
"The solution's pricing could be better."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"What I don't like about Fastly is that they charge a heavy price."
"It's not easy to start with Fastly if you don't have VCL knowledge, so it appears very complex at the beginning."
"Support is not that great."
"The product should provide improved bot detection and management."
"Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users."
"Fastly's customer service area needs improvement."
 

Pricing and Cost Advice

"The price is reasonable."
"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 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."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"We don't have any issues with the price."
"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."
"We are using the free version."
"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."
"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."
"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."
"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 pricing has been very competitive."
"In my opinion, Fastly is priced competitively."
"The solution is cheaper than other products in the market."
"You need to pay a premium price for the tool."
"It is an expensive solution."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"Fastly is less expensive than one of its competitors."
