Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
RonaldoDE Melo - PeerSpot reviewer
Useful for protecting and supporting users against attacks
One problem for me with A10 Thunder TPS is that the box comes from another country in Brazil. In the tool, there is no one key to block it. For example, in F5 Networks, we have a key. If you try to buy another box from Huawei or from F5 and try to enable them in A10 Thunder TPS, you need a key to do it. 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.
Yazan Omar - PeerSpot reviewer
An easy-to-use tool with great GUI
The product's initial setup phase was really easy. There is a lot of time involved in the testing phase and other processes related to the area of deployment, so it may take up to two weeks to deploy the solution. The solution is deployed on an on-premises model. One person is enough to take care of the deployment phase of the product. The person involved in the deployment phase needs to better understand topologies when dealing with Fortinet.

Quotes from Members

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

Pros

"Cloudflare consolidates various capabilities into one product, streamlining processes."
"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."
"Easier http to https redirect using page rules"
"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 features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"The solution is stable, and the DNS servers are simple to use."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"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."
"The solution's support is one of the coolest things about the product. I"
"Thunder TPS has automated mitigation and fully managed support in case the device cannot handle the attack. They have engineers available to respond."
"I had a rather positive experience with A10 Networks Support Service."
"The product's initial setup phase is very simple."
"The solution is easy to use and implement in terms of operations."
"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."
"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 equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"Packet inspection has been effective for mitigating DDoS attacks."
"The product's initial setup phase was really easy."
"It allows me to see all the traffic on my network."
"The solution is very user-friendly and very easy to use."
"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."
"The protection resources and the support are valuable features of the solution."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
 

Cons

"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"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."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"Cloudflare should add more documentation and pricing to the cloud version."
"The solution needs improvement in terms of fail-open."
"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."
"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."
"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."
"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."
"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 is a little expensive."
"I would like for them to develop an advanced reporting feature."
"Alerts and reporting features must be improved."
"I would like to see analytics, big data."
"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The solution can be a little more user-friendly and it can be more affordable."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
 

Pricing and Cost Advice

"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"I give the price a five out of ten."
"We are using the free tier of the solution."
"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."
"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."
"The product's pricing is cheap."
"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."
"The product's pricing is minimal compared to other products."
"We did a price survey, and compared to other solutions, A10 Thunder TPS wasn't cheap."
"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 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 was much higher with Arbor (APS) for the same type of solution."
"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 solution is reasonably priced."
"The product’s pricing needs improvement."
"It's quite pricey."
