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…

Offers flexibility with a kill switch for bypassing Reblaze if needed and provides a reliable Layer 7 defense against attacks

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. AWS WAF, the Web Application Firewall from AWS, has a vast database of bad IP addresses due to its long-standing presence in this business. Reblaze, being a new entrant, is still building its database of bad IP addresses and malicious systems. So, Reblaze needs to work on that aspect. But other than that, I don't think scaling Reblaze has been an issue. There were some initial glitches, but they were all sorted out. So currently, I would say that the bot management and the database are areas they should focus on for further improvement.

Quotes from Members

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

Pros

"CloudFlare's caching brings the load speed down from 4.32 seconds to 2.45 seconds."

"There is no service as mature as Cloudflare that is also as easy to use, reliable, and hosted from excellent infrastructure."

"The attacker won't have details since my public IP is anonymous. It offers us good privacy."

"The UI is good."

"This solution has improved the security of our organization."

"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."

"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."

"The most valuable feature is its usability."

More Cloudflare pros

"It is a very efficient and robust appliance."

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

"The DDoS protection features are valuable."

"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."

"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."

"This is a hybrid solution."

"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 definitely saved us money; we have estimated that it saves up to €500,000 a year."

"We like the website protection, it's really good, and the dashboard is really simple to use."

"The technical support is quite good, as soon as you have an issue you call or send an email and they respond very quickly, and they also provide you with contact details of the CEO."

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

"The feature I find most valuable is the user-friendly dashboard, as it is easy to understand how everything works and it allows you to make decisions quickly and efficiently."

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

"Provides mobile app security."

"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."

Cons

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."

"The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service."

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

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

"The Always Online feature has room for improvement. It seems to work sometimes and not others even with the pro version."

"I would like to not need a separate server for non-www redirection under the CNAME setup option."

"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."

"The installation was complex until I learned what I had to learn."

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."

"Lacks international presence."

"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."

"It could use support in Spanish."

"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."

"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."

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

"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."

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

"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."

"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."

"The WAF features are not as granular as we would expect from a WAF system. There should be more granularity and in-depth rules, out-of-the-box."

"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."

"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."

Pricing and Cost Advice

"The product's pricing is cheap."

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

"We don't have any issues with the price."

"The price of the solution is expensive."

"So far I use free tier and happy with it. You can subscribe to business package if needed."

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

"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."

"There are no additional costs beyond the standard licensing fees."

More Cloudflare pricing and cost advice

"Its price is normal."

"The price of Corero is affordable."

"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."

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

"On a monthly basis we pay $750."

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