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.

Reliable protection ensures robust network defense and simplifies DDoS management

I am not sure if we plan to use additional features because we have many vendors and platforms that we support. We use the main function and that is it. The prices for Arbor DDoS are expensive. The licensing is subscription-based. From our sales department, they discuss that prices are very high. A potential improvement could be establishing a contract with Cisco to sell via their channel. This could be beneficial because we work extensively with Cisco. If you are a Cisco partner, you can sell Arbor DDoS. That would be good for customers that are Cisco-based because many customers in Bosnia are Cisco-based customers. BH Telecom, our main customer, sells Arbor DDoS to other customers for protection. They buy Arbor and sell the product services to others via Internet links. They sell add-on DDoS protection via Arbor DDoS. In Bosnia and Herzegovina, Arbor DDoS is not present in many customers. Some customers try to sell it, but they sell other vendors such as F5. Arbor DDoS is mainly seen in telecom operators but not much in other customers.

Identifies a request that comes up multiple times, block holds that particular IP, and lets the genuine traffic pass through

Genuine traffic coming in is still getting better. While I understand that it's some sort of algorithm that is written in this scale, that algorithm can be a little bit better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked. While it is one of the greatest features it can still be improved. I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense.

Quotes from Members

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

Pros

"I like Cloudflare's application gateway and DDoS protection."

"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."

"The DDoS protection is the most valuable aspect of the solution."

"New and innovative way to protect the client's data."

"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."

"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."

"The overall experience with Cloudflare is positive, with a rating of eight out of ten."

"From what I've seen so far, there are no negatives to report as of yet"

More Cloudflare pros

"Valuable features include simple and centralized management of user access and capabilities, as well as Web 2.0 interactive attack alerting, traffic visualization, and mitigation service control."

"The solution is easy to use."

"The artificial intelligence feature is most appreciated. This solution can lower the throughput and clear the traffic, which is something really important for us. It also provides good protection. It is user-friendly, and its integration has also been really fast. We have many critical applications, and it was easy to integrate Arbor DDoS with our website, mobile application, and web banking."

"It's just one dashboard with mitigation. You decide which mitigation you want and at what threshold to do this or that. Its operation is pretty simple. It's easy."

"The AI capabilities and anomaly detection using machine learning modules like isolation forests and auto-encoders are the most effective in mitigating DDoS attacks."

"It has an easy-to-understand GUI...Stability-wise, I rate the solution a ten out of ten."

"In the GUI, the packet capture is a very good option, as is the option to block an IP address."

"I recommend using Arbor DDoS for those wanting to keep their services online."

More Arbor DDoS pros

"In the DDoS it's difficult to validate what is a genuine request from an end user. We've started being able to do that with the logistics that they have set up. With the protection that they have provided, they are able to identify what is valid and what is not valid. We see that a person who is getting DDoS Neustar service is able to block that particular user. However, while they are doing that it doesn't affect other customers on the server."

Cons

"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."

"The solution could be more user-friendly."

"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."

"Cloudflare could be improved by introducing a mid-tier pricing option."

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."

"The product support needs to be accessible from more places, a wider area of coverage."

"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."

"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."

More Cloudflare cons

"The support got worse after NETSCOUT acquired Arbor."

"The solution needs to enhance its features to compete with other tools."

"There is definitely room for improvement in third-party intelligence and integrations."

"Arbor DDoS has some difficult pricing rules. For many different small features, we have to pay additional fees for every small feature."

"Auto mitigation is a feature provided when DDoS is observed on any of link/customer (configured under auto mitigation). It automatically starts mitigation with default filters. In default filter mode, there could be an impact on the customer’s link,"

"When it comes to some false positives, we need to tweak the system from time to time. There is room for improvement when it comes to the actual mitigation because of some false positives."

"Support in Argentina is not so good. Although the team is good, they are not fast, and they lack the skills to manage dynamic attackers."

"The solution could be more granular to include logs per second and enhanced pipeline monitoring for router licenses."

More Arbor DDoS cons

"I would like to see a dashboard that shows you the data that is transferred from which end. It's where people start looking at abuse management. People keep questioning when the mitigation is on what service it is and how many GBs are passing through. An end user dashboard that will help you identify all of these questions and that can be visible in your entire organization is something that would make sense."

Pricing and Cost Advice

"The product's pricing is cheap."

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."

"We are using the free version."

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

"The price of the solution is expensive."

"We are using the free tier of the solution."

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

"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."

More Cloudflare pricing and cost advice

"Arbor is striking a good balance between pricing and what they deliver."

"The solution is a bit costly if you're a small organization, but I think it's worth the price that they are charging."

"Pricing is slightly on the higher side."

"The solution's pricing is based on a licensing model that is expensive when compared to other tools."

"As far as I know, they are the best in this sector, in DDoS protection. They know it, I know, because their service prices are too high. They provide cloud DDoS protection for ISPs, but that is also too expensive."

"I believe that the price of Arbor DDoS falls under the bracket of medium to high price."

"You need to find a way to get a good offering from Arbor by negotiating a price. That is the challenge."

"Our customers always complain about the price of the product."
