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.

Effective network and DDoS protection with suitable pricing

I use Corero for network DDoS protection projects. It is particularly effective in providing protection against network DDoS attacks I find Corero to be good, especially in a wide area. It does not have application filtering or application DDoS prevention, but for network DDoS projects, it is…

Quotes from Members

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

Pros

"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"

"The most valuable feature is the web application firewall."

"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"

"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."

"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."

"The initial setup is extremely easy but will require access to your Domain Name Servers."

"The solution automatically detects and responds to certain types of traffic based on geolocation."

More Cloudflare pros

"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 ability to correlate Arbor managed objects with internet services deployed accurately profiles traffic and makes coordinating appropriate mitigation response simple."

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

"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."

"Arbor has a global ranking in reliability and credibility and is very unique in its ability to respond to a very wide scope of threats from its global deployment."

"Reporting is quite good. There are several pages of reporting on DDoS attacks, and you can find all the details that you need."

"There are a number of valuable features in this product, like Cloud Signaling and Threat Intelligence feeds."

"I have a lot of experience with the technical support for multiple vendors (HPE, Cisco, Palo Alto Networks, Imperva, etc.) and the Arbor support is really good; usually, they respond with the workaround for your issue."

More Arbor DDoS pros

"It is a good solution, its vendor support is the most valuable, and it is simple and works well if you have Juniper MX routers."

"The DDoS protection features are valuable."

"This is a hybrid solution."

"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."

"The most important aspect, in general, is that the price is suitable for most clients."

"I like the fact that the product provides a hybrid solution."

"It is a very efficient and robust appliance."

"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."

More Corero pros

Cons

"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."

"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."

"The integration of LLMs on the dashboard is something that is needed in the tool."

"There should be a specific price list for enterprise-level customers."

"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."

"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."

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."

More Cloudflare cons

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

"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."

"For troubleshooting problems, it's not so intuitive. It's not straightforward."

"An improvement to Arbor DDoS would be to make evaluation licenses and virtual machines available."

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

"The implementation should be made easier."

"For troubleshooting problems, it's not so intuitive. It's not straightforward. This is the core of their kernel, so they need to improve it a little bit... In F5 I have full control of everything."

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

More Arbor DDoS cons

"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."

"It could use support in Spanish."

"Juniper is known in our country, but it is not very popular."

"Lacks international presence."

"The product must provide more Layer 7 capabilities."

"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."

"I'd like to see an increase in Corero's international team. Our clients are generally companies with an international presence and Corero is not represented in all the countries where our clients have presence."

"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."

Pricing and Cost Advice

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

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

"The product's pricing is cheap."

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

"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."

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

"There are no additional costs beyond the standard licensing fees."

"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."

More Cloudflare pricing and cost advice

"Arbor DDoS is quite expensive, but all these solutions are expensive because they deal with confidential information."

"The price of Arbor DDoS depends on many parameters. It depends on the physical capacity of the environment, and it is not a straight-line price. It's fairly competitive in the market on the price."

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

"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 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."

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

"Regarding pricing, I would rate it as average. Arbor DDoS offers good value for money with our DDoS filter device. For higher protection needs, Arbor’s CloudMeter’s DDoS mitigation or hardware devices might be more expensive, but customers who need them are usually prepared for the cost and the additional resources required."

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

More Arbor DDoS pricing and cost advice

"Its price is normal."

"The price of Corero is affordable."
