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.

Automated threat intelligence and flow-based mitigation have improved our DDoS defense

A very useful feature in Arbor DDoS is its ability to send flow spec announcements to routers. For example, if it is clear that a Layer 3 or Layer 4 attack is occurring and the attack pattern is identified through source and destination IP addresses and ports, you can generate flow spec filters. These filters are transferred through BGP to border routers, which automatically build filters, mitigating the attack even at the network's boundary and preventing it from reaching the TMS. This allows the TMS to focus on other tasks. This is a highly effective feature that can mitigate huge volumetric attacks; for example, we experienced a 32-gigabit attack, and all those 32 gigabits were dropped by our border routers, not by Arbor DDoS itself. The flow spec announcement was generated by Arbor DDoS, and as far as I know, the same technology is used by Radware, but it comes under a different feature and a different license. At the time, we were told that flow spec mitigation was an additional very expensive license to purchase from Radware, while Radware included everything in one package.

Quotes from Members

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

Pros

"Cloudflare is very straightforward."

"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."

"It is a fast and secure DNS."

"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."

"The aggressive caching and DDOS mitigation are the most valuable features offered by Cloudflare."

"Cloudflare has positively impacted our organization by giving us flexibility to manage the DNS part, being quite fast, and allowing us to manage everything from a single dashboard, which is quite handy."

"The solution offers the flexibility to control configuration rules."

"There are key things that are used for our enterprise customers, such as Lambda and DNS."

More Cloudflare pros

"The Arbor Networks SP device provided great visualization of the network traffic."

"We are able to respond quickly and prevent DDoS attacks."

"The solution provides good protection against volumetric DDoS attacks."

"Without Arbor, we'd probably be around 75 to 80 percent uptime."

"There were huge attacks in October, around 62 attacks at 30 gigabits per second, at one of our banks. We used Arbor DDoS to mitigate these attacks, and it performed great."

"Arbor Pravail APS devices provide easy management, high visibility, and quick response capabilities."

"The product allows us to check real-time progress, including latency and network activities."

"Arbor's technical support is very good, we've had no issues with it."

More Arbor DDoS pros

"We have researched them all, and it's a good solution all around."

"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 product allows the users to adjust the thresholds."

"It allows me to see all the traffic on my network."

"I find this product the best on-premises (in-line) DDoS mitigation solution that suits my current and future requirements."

"The product's initial setup phase was really easy."

"We use it to protect our users and their data."

"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."

More Fortinet FortiDDoS pros

Cons

"The product needs to improve its automation."

"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."

"However, what I still fail to understand is that why aren't they offering domains themselves."

"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."

"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."

"Support response time could be improved."

"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."

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

More Cloudflare cons

"It is an expensive product, so there is room for improvement in terms of pricing."

"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, e.g., if we have enabled monitoring of internal traffic for that link/customer, it starts mitigation on legitimate traffic."

"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."

"They should improve the reporting section and make it a little bit more detailed. I would like to have much better and more detailed reports."

"On the application layer, they could have a better distributed traffic flow. They could improve that a bit. For network data it is very effective, but the application layer can be improved."

"Arbor's SSL decryption is confusing and needs external cards to be installed in the devices. This is not the best solution from an architectural point of view for protecting HTTPS and every other protocol that is SSL encrypted."

"The look and feel of the management console is a little old, excessively simple."

"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."

More Arbor DDoS cons

"The initial setup is complex. It is always complex."

"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."

"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."

"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 tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."

"I would like to see analytics, big data."

"Alerts and reporting features must be improved."

Pricing and Cost Advice

"We are using the free version."

"I give the price a five out of ten."

"A free version of the solution is available."

"We don't have any issues with the price."

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

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

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

"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."

More Cloudflare pricing and cost advice

"The pricing of the solution is cheap."

"The price of this solution is a little high in the African market, it should be lower."

"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."

"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."

"The price is a little high."

"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."

"Because the solutions from competitors are very different, it's not easy to compare. However, the licensing from Arbor is clear and understandable and the pricing is reasonable when looking at the market, in general."

More Arbor DDoS pricing and cost advice

"The solution is reasonably priced."

"The product’s pricing needs improvement."

"It's quite pricey."
