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…

Exceptional resilience and protection well-suited for medium to large businesses

The initial setup process is quite straightforward. Its complexity largely depends on the intricacies of your platform. If your platform spans multiple sites across the globe, requiring configuration of multiple instances and traffic routing, it can become more intricate. From our experience, even in companies with extensive platforms, the configuration process remains relatively simple. Once the instances are spun up and the initial configurations are in place, you can use their console application to set up your site or sites for traffic management. This involves configuring the sites and uploading SSL certificates. Even for those not well-versed in the intricacies of networking layers and rules, the out-of-the-box configurations already provide solid protection.

Quotes from Members

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

Pros

"The solution is a great fit for customers who want unlimited bandwidth."

"The most valuable feature of Cloudflare DNS is security."

"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."

"DDoS protection is this product’s most valuable feature."

"Cloudflare improves performance on my websites and is a great partner for cloud infrastructure for anyone who wants to use the security service and other features."

"Cloudflare consolidates various capabilities into one product, streamlining processes."

"So far I use free tier and happy with it."

"New and innovative way to protect the client's data."

More Cloudflare pros

"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."

"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."

"This is a hybrid solution."

"It is a very efficient and robust appliance."

"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."

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

More Corero pros

"Reblaze has saved us money by optimizing server usage and blocking malicious bots."

"Reblaze has just made things simpler for us."

"It is a highly resilient product that can handle significantly larger workloads and high volumes of traffic with ease."

"I very much like the elastic search and reports, allowing us to have a 360-degree view of the customer's activities and enabling us to track down any suspicious bots."

"It saved us a lot of time and money and we were able to use fewer resources on our side, saving about $15,000 to $20,000 a year in computing resources because we had the reverse proxy and the caching mechanism and used the platform as a CDN as well."

"The best thing about Reblaze, for us, is that it has been a game changer because previously, we were using Google's Web Application Firewall, but it wasn't up to the mark."

"Reblaze provides us with a solution we can count on."

"The most valuable features were the real-time monitoring and the management. With this kind of product, you need a very good management system to allow you to see false positives in real-time; to see what's happening in real-time... The clarity stood out. It was very visible and very easy to navigate; very easy to find the data we were looking for."

Cons

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

"DNS Management."

"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."

"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."

"For the services I am using, it is a bit expensive."

"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."

"Access to the solution's dashboards is not intended for a service company. You are practically blind, and to validate a problem, you must view the customer's screen."

"However, what I still fail to understand is that why aren't they offering domains themselves."

More Cloudflare cons

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

"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."

"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."

"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."

"Lacks international presence."

"The interface on the dashboard could be improved. Some of the settings are confusing which makes things difficult when you're trying to get a handle on the product."

"I would like to have seen more automated reports. Maybe it has been improved in the last year and I'm just not aware of it. But from a managerial point of view, you want a summary report, a weekly report: How many attacks were blocked? How much bandwidth was saved due to the caching mechanism? What were the top-ten attacks that were tested on the network, etc? I could most likely have found all that data if I logged in to the system and ran different reports. It would be very helpful to get a management report on a weekly basis."

"There is room for improvement in helping us understanding session management... We want Reblaze to catch and identify everything. We want to see the various devices doing one activity and to see, in a timeline, what's happened. We would like to see a more human-readable display to understand what's happening in the web app."

"We have multiple products behind different instances of Reblaze. We have one instance for staging and then we have a production instance for multiple products. One of the things that we have requested is a unified view panel, so that we can see each of the instances in a unified view. That way, we won't have to go bouncing from instance to instance."

"The next release should have next-generation automation."

"Up to now the only cons I could find is sometimes getting change management back on track, because it's a company that evolves, and sometimes I don't have the same needs that they have. But besides that, up until now, I am really pleased with their service and I've also recommended them to some of my clients."

"It would be beneficial if it had a workflow or a feature that could fine-tune settings based on high-level requirements."

"They have an interface that you have to adjust to. That is a bit of a downfall because I expect an interface to be very intuitive for someone who knows little about security. But if you know about security, the interface is wonderful."

Pricing and Cost Advice

"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."

"A free version of the solution is available."

"The solution is expensive when compared to other products but offers unlimited bandwidth."

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

"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."

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

"We are using the free version."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

More Cloudflare pricing and cost advice

"The price of Corero is affordable."

"Its price is normal."

"On a monthly basis we pay $750."

"We found the cost to be a bit on the higher side, starting at approximately three to four thousand dollars for a small configuration."

"There is still some room for improvement when it comes to bot management from Reblaze because they are relatively new compared to other vendors in the town."

"I believe that for the six instances we have right now, it's costing us $16,000 per month."
