General Manager at bKash Limited
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.

Customer interface and support have impressed while artificial intelligence features drive confidence
Arbor DDoS has some difficult pricing rules. For many different small features, we have to pay additional fees for every small feature. If we compare it, it is slightly high and not very affordable. If I compare it to automobiles, when you buy Volkswagen and then consider Skoda, for the cheapest way, you would buy Skoda. But if you want similar features to Volkswagen, you have to pay a little bit more than for Volkswagen. As I mentioned, a good way would be to buy some package of features at small prices. That is one of my recommendations for the company. I would like to see a roadmap for one or two years, and it is tough to predict what will happen in that timeframe without a clearer description.

Reliable protection and smooth setup enhance company security
Currently, I have two firewalls, with one located in Sorocaba, model 90D, and the other in São Paulo, model 30D. They are connected by VPN. I use the firewalls for VPN and final protection for my company, and my equipment is maintained by an internet company called Multiprox The equipment works…

Quotes from Members

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

Pros

"I rate its stability a ten out of ten."
"New and innovative way to protect the client's data."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"DDoS protection is this product’s most valuable feature."
"Their free account offers an awful lot of functionality and savings alone, before you get on to the minimal $20 a month for a Pro account which comes with its own great list of features."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"So far I use free tier and happy with it."
"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."
"We also use it by serving our customers' cloud signaling services with on-premise APS devices."
"The technical support of Arbor DDoS is good."
"It's very user-friendly."
"We have gained from this product, and our customers are also satisfied with this solution."
"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 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."
"Mitigating network level volumetric attacks, complete network visibility and complete control on applying countermeasures."
"Packet inspection has been effective for mitigating DDoS attacks."
"The product allows the users to adjust the thresholds."
"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 most valuable feature is the cloud DDoS scrubbing capability."
"The pricing of this solution is better than that of Cisco and other software on the market, which are very expensive."
"We have researched them all, and it's a good solution all around."
 

Cons

"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 does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"The product needs to improve its automation."
"CloudFlare doesn't provide the cache flush history. I am not able to find out the URL information of those I have recently flushed."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"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."
"There should be a specific price list for enterprise-level customers."
"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."
"Based on my experience and feedback from colleagues, Arbor can make better use of the product because you have to spend a lot of time finding information in a huge number of papers."
"There is always room for improvement for any product or service. If we can bring in more agility when deploying services, that is definitely a scope which we can work towards. Nowadays, everything is being offered as a service model. It is not that we have to deploy the physical hardware, many things move up to the cloud, or even can be delivered in the VNS form in the customer's environment as well. So, in that space, if we can add more features to make it more seamless for customers to use and make it available through some marketplace, not only at the hyperscalers, but also for any on-prem deployment, that definitely would be a big plus."
"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."
"There is some room for AI to take place."
"An improvement would be to provide information on how pricing is done on different customer levels (e.g. is it done per gig or bandwidth?)."
"There is definitely room for improvement in third-party intelligence and integrations."
"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."
"I have observed that the SNMP traps aspect that sends information to third-party solutions needs improvement."
"I would like to see analytics, big data."
"All those 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."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"Alerts and reporting features must be improved."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
 

Pricing and Cost Advice

"We don't have any issues with the price."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The tool is a premium product, so it is very expensive."
"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."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"We are using the free version."
"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."
"The product's pricing is cheap."
"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."
"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 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."
"The pricing of the solution is cheap."
"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."
"We do not use the Arbor Cloud DDoS solution because it is too costly."
"There is room for improvement with the pricing. It is an expensive solution. The issue with the pricing is more the way it is built. Right now we're paying per router, and there's a limitation there. I would like to see bundle-pricing where there is an overall solution cost."
"It's quite pricey."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
