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.

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…

Traffic insights have reduced transit costs and support secure, direct connections with providers

The best features that Kentik offers are the ability to identify traffic end-to-end and to know which transit is used, if it goes through any other transit, to see the entire flow, from the subscriber to the content provider and vice versa, from the content provider to the subscriber.I can also determine whether it is symmetric or asymmetric traffic, and if it goes through any provider that has some kind of bottleneck. That is very important. Regarding the security part, which is also possible to handle through Kentik, you can configure it in a way that makes the network more secure and reduces the amount of dirty traffic or attacks received. Kentik has had a high positive impact on my organization. Besides the cost reduction, it has been possible to perform troubleshooting more effectively, and also regarding DDoS-related attacks. In addition to cost reduction, we had a more reliable connection. Since the moment we identified that it was possible to have a direct connection with content providers like CDN77, Cloudflare, and Akamai, we established a direct connection there through a PNI with these content providers, making the network less dependent on an IP transit provider.

Quotes from Members

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

Pros

"Cloudflare's DNS services deliver the best performance in terms of speed and reliability."

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

"It's very user-friendly."

"The tool is user-friendly."

"The technical support is good."

"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."

"If you don't want to spend too much time hosting your own DNS server or managing the domain, Cloudflare is a great way to rapidly get websites and services online."

"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."

More Cloudflare pros

"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 DDoS protection features are valuable."

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

"This is a hybrid solution."

"It is a very efficient and robust appliance."

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

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

"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."

More Corero pros

"The most valuable features have been anything around traffic engineering: being able to determine the source or destination of a surge of traffic, whether it's DDoS-related, or a customer just happened to have a sudden uptick in traffic. Being able to tell where that's coming from or where it's going to enables us to do things based on that."

"I can say that I am so happy with this platform because it is very useful for us."

"Kentik is worth the money to have as a tool."

"Kentik has positively impacted the organization by providing greater control over certain subjects and enabling monitoring of current traffic."

"Kentik has had a positive impact on my organization in terms of our network visibility because we leave our dashboard on a display screen, where the entire engineering team can see it."

"Overall, I would give Kentik nine out of ten stars."

"Kentik has positively impacted my organization significantly, as it serves as our main monitoring system."

"One of the valuable features is the intuitive nature of building out reports, and then triggering actions based on specific metrics from those reports. It has a really good UI and the ability to surface data through the reporting functions is pretty good. That's helped a lot in the security space."

More Kentik pros

Cons

"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 provide the cache flush history. I am not able to find out the URL information of those I have recently flushed."

"I rate technical support quite badly."

"More insight into analytics and threats would be a good place to start improving Cloudflare."

"Honestly the product has not really improved the way of my organisation."

"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."

"There should at least be a read-only view of the data so that resellers can properly support the clients."

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

More Cloudflare cons

"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."

"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."

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

"The product must provide more Layer 7 capabilities."

"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."

"It could use support in Spanish."

"Lacks international presence."

"Perhaps a better explanation would be to see how tagging is captured and a method of comparing my tagged interfaces on Kentik’s side."

"It also detects anomalies proactively, but the same is not so true when it comes to real network problems, since they tend to just happen."

"They're moving more in a direction where they are saying, "Hey, here's information that you may be interested in or may a need," before the question has to explicitly be asked. Continuing to move in that direction would be a good thing."

"I've checked out the V4 version of the interface and it's still a little bit clunky for me to use. I still go back to the old interface. That's definitely one that they still need to work on. It doesn't seem like everything that you get in the V3, the older interface, is there. For instance, I was trying to add a user or do the administrative tasks in V4, and I couldn't figure out where I was supposed to do that."

"Sometimes it's difficult to order the dimensions correctly when trying to make Sankey flow diagrams."

"There is a large difference between BGP and normal nodes. I don't think this plays out to the best for the customer or Kentik."

"The product could strive for more improvements to become closer to perfect."

"Currently, the way I'm configuring it uses reactive alerts, which means alerts are triggered when an issue occurs. I would prefer more proactive alerts in the future."

More Kentik cons

Pricing and Cost Advice

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

"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."

"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."

"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."

"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."

"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."

More Cloudflare pricing and cost advice

"The price of Corero is affordable."

"Its price is normal."

"The tool is cheaply priced."

"We have an annual contract with Kentik that we renew each year for a set number of licenses. We also have some burstable licenses which we can spin up and spin down, and those are paid as they are used."
