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.

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

"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 the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."

"Cloudflare makes it easier for me to handle and set up DNS for multiple users and multiple clients, and basically go in and access their account, make the changes they need, and it's a one-stop shop."

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

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

"The most valuable features of the solution are performance and security."

"Generally, I am satisfied with this product."

"It's very user-friendly."

More Cloudflare pros

"It is a scalable solution."

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

"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."

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

"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."

More A10 Thunder TPS pros

"Fastly provides CDN, WAF, image optimization, and IP restriction."

"Compute@Edge features are valuable to me."

"The product's initial setup phase is straightforward."

"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 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."

"Its initial setup process is straightforward."

"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."

More Fastly pros

Cons

"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."

"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."

"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."

"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."

"Integration involving API with other products could be more user-friendly."

"There are some issues with the CDN services."

"There should be a specific price list for enterprise-level customers."

"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

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

"Its documentation could be better."

"We have had some issues with implementation. So, it is the only area that needs improvement."

"The solution is a little expensive."

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

"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 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 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."

More A10 Thunder TPS cons

"The product should provide improved bot detection and management."

"The solution's pricing could be better."

"Support is not that great."

"What I don't like about Fastly is that they charge a heavy price."

"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."

"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."

"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."

"Fastly's customer service area needs improvement."

Pricing and Cost Advice

"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."

"The solution is expensive when compared to other products but offers unlimited bandwidth."

"The product's pricing is minimal compared to other products."

"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."

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

"A free version of the solution is available."

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

"I give the price a five out of ten."

More Cloudflare pricing and cost advice

"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 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."

"The tool is expensive. If one is low price and ten is expensive, I rate the tool's price as a ten."

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

"Pricing is very reasonable."

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

"The pricing has been very competitive."

"Fastly is less expensive than one of its competitors."

"You need to pay a premium price for the tool."

"In my opinion, Fastly is priced competitively."

"It is an expensive solution."

"The solution is cheaper than other products in the market."

"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
