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.

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

"The attacker won't have details since my public IP is anonymous. It offers us good privacy."

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

"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."

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

"I didn’t have to pay anything for better website security and reduced server load."

"The setup and configuration is also easy to perform and their support is excellent."

"The technical support is good."

"Because our website is blazing fast it improves our conversion rates."

More Cloudflare pros

"Arbor DDoS helps consolidate visibility on traffic and on DDOS attacks attempts, can perform direct mitigation action on the network, and has helped us achieve our network and application uptime goals."

"Arbor DDoS is easy to use, provides effective blocking of DDoS attacks, and can be used for DNS, web, and main servers. Additionally, this solution is far easier to operate than others solutions, such as Fortinet DDoS."

"The most valuable features include the traffic categorization and control of the traffic. The filtering of the traffic is very precise. When you want to stop some traffic, you precisely stop that traffic."

"With real-time packet capture features, you can easily and quickly response."

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

"Don't worry that it is complex because, out-of-the-box, it protects you from the basics."

"We use it not only for DDoS detection and protection, but we also use it for traffic analysis and capacity planning as well. We've also been able to extend the use of it to other security measures within our company, the front-line defense, not only for DDoS, but for any kind of scanning malware that may be picked up. It's also used for outbound attacks, which has helped us mitigate those and lower our bandwidth costs..."

"The technical support of Arbor DDoS is good."

More Arbor DDoS pros

"Scalability is awesome, and they have grown two folds or three folds since we started using them, with no concerns even as we protect close to 60,000 hosted sites for business and e-commerce customers."

"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

"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."

"The solution could work at being less expensive. It costs a lot to use it."

"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."

"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."

"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."

"I have found CloudFlare's support to be unresponsive at times, and not very helpful with providing technical details for issues that we have reported over the years."

"It looks like they don't support as many TLDs as other registrars, but since they are very new as a registrar, I expect this may improve soon."

"For the services I am using, it is a bit expensive."

More Cloudflare cons

"Sometimes it blocks legitimate traffic. If a legitimate user is trying to access the server continuously, the product suspects that this is a DoS traffic file. That is a case where it needs to improve. It needs machine-learning."

"As long as you don't touch it, it's very stable. But if you try to configure new features or some new deployment, sometimes that can be a problem."

"The following areas need improvement: Opening and tracking support tickets, online support resources, software upgrades/updates and replacement media, and event management guidelines."

"The regional support here in African could improve, such as marketing and account managers."

"This is a disadvantage of Arbor DDoS, as it operates merely as a flow collector, generating alerts only after a violation occurs."

"It could include a lot of enhancements related to AI and automation."

"We need a SaaS model for the solution."

"I think the diversity of protection is extremely limited. It must be expanded in future upgrades and versions."

More Arbor DDoS cons

"Genuine traffic coming in is still getting better because sometimes while we are doing DDoS mitigation, genuine traffic does get blocked."

"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

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

"The product's pricing is cheap."

"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."

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

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

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

"That is one of the great features. I was able to access the majority of the features and services for free."

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

More Cloudflare pricing and cost advice

"The licensing of a complete Arbor solution, including fire-walling and unified site management, can get expensive."

"I'm a technical guy. But I know it's expensive compared to its competitors. After you have the on-premise solution, for your solution to be effective you have to subscribe to an "upper level," so there's another cost. There is also a subscription to cloud services, which is another cost."

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

"I don't know about the pricing details as our company's service provider offers us the solution as an inbuilt feature within the internet bandwidth they provide us."

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

"Arbor's products are very expensive. Their competitors are cheap when compared with Arbor."

"The price is a little high."

"Start with a small license. Measure your bandwidth requirements."
