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.

Optimized ecommerce performance and improved access control through image handling and IP filtering
I believe that Fastly should provide guidelines for their WAF blocking rules. It should be public what the rules are that are blocking their contents. I believe Fastly should provide regional IP addresses instead of POP IPs. Fastly should provide features similar to Cloudflare regarding a block list. Additionally, a POP address should be there with a wide range of IP addresses provided, public static IP addresses, so customers can integrate egress IPs. Fastly should provide WebP image processing on the backend instead of on the fly. It would be a very useful feature to avoid unnecessary time for browser to browser and local cookies. I believe that Fastly service has a few gaps. We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers. There should be transparency.

Quotes from Members

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

Pros

"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."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The setup and configuration is also easy to perform and their support is excellent."
"From what I've seen so far, there are no negatives to report as of yet"
"It's a reasonably priced solution that meets customers' needs and it's not too difficult to deploy."
"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."
"The solution is very good at mitigating threats."
"Cloudflare has many features."
"I had a rather positive experience with A10 Networks Support Service."
"The solution is easy to use and implement in terms of operations."
"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."
"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."
"We can keep track of all the customer's requirements. We can forecast our trails and we can forecast our overall financial things."
"It is a scalable solution."
"They give us the ability to configure many features for DDoS. There are many items that we can use."
"The product's initial setup phase is straightforward."
"Rate limiting is a good feature that protects from volumetric attacks."
"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."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
"Its initial setup process is straightforward."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"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."
"Compute@Edge features are valuable to me."
 

Cons

"Technical support is lacking."
"Yes, there were a few times when some of their CDN nodes would fail, creating serious speed issues with the site without any warning or notification from their side."
"Perhaps I would ask that they improve the Free plan and allow us to use it with any TLD (certain ones are not allowed)."
"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."
"I rate technical support quite badly."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"CloudFlare doesn't provide the cache flush history. I am not able to find out the URL information of those I have recently flushed."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"The solution is a little expensive."
"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."
"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."
"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."
"The solution needs improvement in terms of fail-open."
"I would like for them to develop an advanced reporting feature."
"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 solution's pricing could be better."
"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"Support is not that great."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"The product should provide improved bot detection and management."
"Fastly's customer service area needs improvement."
"What I don't like about Fastly is that they charge a heavy price."
 

Pricing and Cost Advice

"That is one of the great features. I was able to access the majority of the features and services for free."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The cost primarily depends on the size of the organization."
"The price is reasonable."
"The product's pricing is cheap."
"A free version of the solution is available."
"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."
"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."
"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 is very reasonable."
"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 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."
"In my opinion, Fastly is priced competitively."
"Fastly is less expensive than one of its competitors."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"You need to pay a premium price for the tool."
"It is an expensive solution."
"The pricing has been very competitive."
"The solution is cheaper than other products in the market."
