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

"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."

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

"I like Cloudflare's application gateway and DDoS protection."

"The solution provides good load balancing and protection against DDoS attacks."

"It is easier to configure and develop documentation to see how we have configured firewalls."

"It is a fast and secure DNS."

"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."

"It is a fast and secure DNS."

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 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."

"This is a hybrid solution."

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

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

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

"The DDoS protection features are valuable."

"The most valuable feature is being able to pull traffic patterns; to and from destinations. We're able to understand where our traffic is going, our top talkers from an AS set, as well as where our traffic's coming from."

"Having the API access allows us to do a great deal of automation around a lot of our reporting and management tools."

"It offers a simple yet powerful feature of classifying applications, going beyond basic statistics."

"We're pretty happy with the API functionality. It's web, and it's very simple to set up queries. It has served us well and you don't need to be an expert on the API or the product to set these things up."

"In terms of the solution’s real-time visibility across our network infrastructure, I have not been able to find any other monitoring or netflow visualization tool that gives me the kind of information I get from Kentik. If I need to take a deep-dive into something that I see, it's really easy for me to do that. Whereas with most other things, I have to use five or six other tools to get that kind of data, with Kentik, I have it all in one place."

"We're also using Kentik to ingest metrics. It's a useful feature, and its response time, whenever we're pulling back the data, is higher than our on-prem solution."

"The most important feature is cybersecurity."

"Overall, the ease of use and the fact that it meets client expectations are major positives."

More Kentik pros

Cons

"Technical support is lacking."

"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."

"The pricing could be improved."

"In the last two years, there has been a certain amount of downtime when using the VDM."

"An integrated SSO feature would be useful for Cloudflare DNS."

"The product support needs to be accessible from more places, a wider area of coverage."

"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."

"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."

More Cloudflare cons

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

"The product must provide more Layer 7 capabilities."

"Lacks international 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."

"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."

"Sometimes, the tool has complications, so we must deal with the additional support from the tool's end."

"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 should say, as someone who's not in networking, maybe it's easier for people who are in networking, but for me that one part is not very user-friendly."

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

"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. Kentik is valuable, don't get me wrong, but if it had an actionable piece to it..."

"I would like to see them explore the area of cost analysis."

"We had faced some issues during an outage and were not able to get the desired results from Kentik tools. It took time to resolve these issues, which is why I give them eight points."

"In recent months, I've noticed that while the industry is trending towards AI, Kentik has room for improvement in this area."

"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."

More Kentik cons

Pricing and Cost Advice

"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."

"The tool is a premium product, so it is very expensive."

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

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

"The cost primarily depends on the size of the organization."

"A free version of the solution is available."

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."
