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…

Network monitoring is improved through multi-vendor integration and effective observability
In recent months, I've noticed that while the industry is trending towards AI, Kentik has room for improvement in this area. Specifically, more work is required to integrate AI for troubleshooting, simplifying root cause analysis, and providing suggested solutions for network issues. Although Kentik has a market presence, it lags behind Selector AI, which is a leader in integrating AI to support network operations.

Quotes from Members

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

Pros

"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."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"The API gives us the ability to remote control our DNS settings."
"Using the CDN of Cloudflare improved the speed significantly, reducing the page loading times to appropriate levels."
"The most valuable features of the solution are performance and security."
"I rate its stability a ten out of ten."
"The solution offers the flexibility to control configuration rules."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"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."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"It is a very efficient and robust appliance."
"The most important aspect, in general, is that the price is suitable for most clients."
"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."
"I like the fact that the product provides a hybrid solution."
"The drill-down into detailed views of network activity helps to quickly pinpoint locations and causes. All the information is there."
"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."
"Before using the solution, we had to do all these manual tasks, such as running all these queries manually, and building our tech cost-report used to be a two or two-and-a-half-week effort, and using Kentik, and the automation that it provides us, we've brought that down to a day or two, which is a massive time savings."
"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."
"Overall, I would give Kentik nine out of ten stars."
"Overall, the ease of use and the fact that it meets client expectations are major positives."
"Monitoring operational efficiency is easy."
"The most important feature is cybersecurity."
 

Cons

"Honestly the product has not really improved the way of my organisation."
"Several features that I think is essential is not available in the free and business package."
"Perhaps I would ask that they improve the Free plan and allow us to use it with any TLD (certain ones are not allowed)."
"We experienced some downtime in the fall of 2013, causing us to switch to Incapsula."
"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."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"I would like to not need a separate server for non-www redirection under the CNAME setup option."
"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."
"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 product must provide more Layer 7 capabilities."
"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."
"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."
"Lacks international presence."
"It could use support in Spanish."
"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."
"I consider the pricing model as an area for improvement."
"There is room for improvement around the usability of the API. It's a hugely complex task to call it and you need a lot of backing to be able to do it."
"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. With more companies going hybrid, flow logs and flow data, whether it be VPC or on-prem, matched with application performance and trace data, is pretty important."
"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."
"In recent months, I've noticed that while the industry is trending towards AI, Kentik has room for improvement in this area."
"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."
"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."
 

Pricing and Cost Advice

"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."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The price is reasonable."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"We are using the free tier of the solution."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The tool is a premium product, so it is very expensive."
"There are no additional costs beyond the standard licensing fees."
"Its price is normal."
"The price of Corero is affordable."
"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."
