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

"The solution offers the flexibility to control configuration rules."
"The API gives us the ability to remote control our DNS settings."
"I have used it to bring enterprise-grade features to my small business clients at low or no cost."
"Because our website is blazing fast it improves our conversion rates."
"CloudFlare has positively improved my site's speed, performance and security."
"We're partners with Cloudflare; this solution is the best product and it does not charge you for any kind of attack on your traffic, only for good traffic, and it can mitigate up to 30 TBPS of DDoS attacks."
"Cloudflare is very straightforward."
"DDoS protection is this product’s most valuable feature."
"We have taken on the Arbor Cloud subscription, which is really useful because you secure yourself for anything beyond your current mitigation capacity. This is a really good feature of Arbor that is available."
"The auto-mitigation, that signaling feature, where it automatically raises an alarm that a line is under attack, is important. The upstream service provider will then do something to reduce the load on our internet lines. The fact that it's automated means I don't have to sit and always be looking at threats coming through. It does it almost automatically, without any intervention by me."
"Very user-friendly GUI Simplest way of mitigation Predefined filters/techniques to easily stop the attacks and start mitigation."
"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."
"The analytics part of Arbor DDoS is great, and we are satisfied with the reporting and analytics part, especially the new version."
"It's very user-friendly."
"Without Arbor, we'd probably be around 75 to 80 percent uptime."
"When there was an attack, the attack was contained only on the IPs under attack, the rest of the network was not impacted, and that is the most important part."
"The most valuable feature is the cloud DDoS scrubbing capability."
"We've been completely satisfied with the product."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The solution is very user-friendly and very easy to use."
"The product allows the users to adjust the thresholds."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us, and this is important."
"We use it to protect our users and their data."
 

Cons

"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"There should be a specific price list for enterprise-level customers."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"We had to do a lot of digging and back-and-forth with technical support for specific use cases, and it might be helpful to have more screencasts or screenshots for common situations."
"However, what I still fail to understand is that why aren't they offering domains themselves."
"There are some issues with the CDN services."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"There is some room for AI to take place."
"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."
"I think the diversity of protection is extremely limited. It must be expanded in future upgrades and versions."
"Arbor DDoS could improve out-of-the-box reporting, it could be better."
"They also have limited sizes of the boxes. Different sizes are needed because some customers are very small while others are very big, such as ISPs, so this categorization should be available."
"The solution could be more granular to include logs per second and enhanced pipeline monitoring for router licenses."
"Arbor Pravail APS devices do not sync features or config the backup enough. This needs to be improved."
"A small improvement could be a better reporting system."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"Alerts and reporting features must be improved."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"Earlier versions of firmware had bugs that limit my options."
"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."
 

Pricing and Cost Advice

"We are using the free tier of the solution."
"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."
"There are no additional costs beyond the standard licensing fees."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"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 cheap."
"That is one of the great features. I was able to access the majority of the features and services for free."
"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."
"Arbor DDoS is quite expensive, but all these solutions are expensive because they deal with confidential information."
"The licensing of a complete Arbor solution, including fire-walling and unified site management, can get expensive."
"The solution's pricing is based on a licensing model that is expensive when compared to other tools."
"Arbor's products are very expensive. Their competitors are cheap when compared with Arbor."
"The pricing of the solution is cheap."
"We do not use the Arbor Cloud DDoS solution because it is too costly."
"It is an expensive product. I use this product for its different features."
"I don't deal with the pricing, but it seems that you need to get basic support in order to upgrade the software and implement some patches."
"The solution is reasonably priced."
"It's quite pricey."
"The product’s pricing needs improvement."
