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…

Integrating synthetic tests and network monitoring enhances traffic pattern visualization
The Kentik support team is good. If you want me to rate them on a scale, I would give them eight. I had a call with the Kentik support team for fifteen minutes, so I'm going to give them eight for now. The reason for giving them an eight is that they are good and address our issues. They have monthly calls and discuss the product roadmap with us, including what is needed and what is not. However, when we are working on some real issues with Kentik, I sometimes feel there's a delay due to the busyness of their teams. We faced some outages and were not able to get the desired results from Kentik tools, so that took a little time to resolve.

Quotes from Members

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

Pros

"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."
"The solution provides good load balancing and protection against DDoS attacks."
"The most valuable feature of Cloudflare DNS is security."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"Cloudflare is easier to manage than the solutions provided by these vendors, and the user experience is much more straightforward and appeals to a lot of developers."
"I rate its stability a ten out of ten."
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"From what I've seen so far, there are no negatives to report as of yet"
"The most important aspect, in general, is that the price is suitable for most clients."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"This is a hybrid solution."
"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."
"It is a very efficient and robust appliance."
"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."
"I like the fact that the product provides a hybrid solution."
"Honestly, it is one of those products that I would suggest to almost any network operator."
"I am able to do a lot of work on the visualization end to create different visualizations and different ways to get information out of it."
"This product is easily the best network monitor that I’ve ever seen or heard about."
"Kentik is worth the money to have as a tool."
"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."
"The drill-down into detailed views of network activity helps to quickly pinpoint locations and causes. All the information is there."
"Technical support is second to none."
"We haven't seen anything else that comes even close to Kentik's real-time visibility across our network infrastructure, and we've demo'ed everything under the sun."
 

Cons

"More insight into analytics and threats would be a good place to start improving Cloudflare."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States."
"The product needs to improve its automation."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"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."
"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."
"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"I have found CloudFlare's support to be unresponsive at times, and not very helpful with providing technical details for issues that we have reported over the years."
"Juniper is known in our country, but it is not very popular."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"Lacks international presence."
"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."
"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."
"It could use support in Spanish."
"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."
"The product must provide more Layer 7 capabilities."
"I consider the pricing model as an area for improvement."
"I believe they're already working on this, but I would love for them to create better integrations from network flow data to application performance — tracing — so that we could overlay that data more readily."
"Perhaps a better explanation would be to see how tagging is captured and a method of comparing my tagged interfaces on Kentik’s side."
"The only downside to Kentik, something that I don't like, is that it's great that it shows you where these anomalies lie, but it's not actionable."
"Sometimes, the tool has complications, so we must deal with the additional support from the tool's end."
"We asked for a way, regarding the potential networks that exist, to hook Kentik up with external tools like peering DBs to correlate things together and see what we can do... This is all in the [next] beta now."
"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."
"I would like to see them explore the area of cost analysis."
 

Pricing and Cost Advice

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The cost primarily depends on the size of the organization."
"The product's pricing is cheap."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The price of the solution is expensive."
"The price of Corero is affordable."
"Its price is normal."
"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."
"The tool is cheaply priced."
