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

"Using the CDN of Cloudflare improved the speed significantly, reducing the page loading times to appropriate levels."

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

"The DDoS protection is the most valuable aspect of the solution."

"Cloudflare has many features."

"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."

"If someone is looking for a secure and optimized wrapper over an open website, I would suggest CloudFlare services."

"The most valuable feature is the web application firewall."

"The most valuable features of the solution are performance and security."

More Cloudflare pros

"The DDoS protection features are valuable."

"It is a very efficient and robust appliance."

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

"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."

"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, and it is simple and works well if you have Juniper MX routers."

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

More Corero pros

"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."

"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."

"The real-time monitoring and reporting are very good. There are information updates in their portal every two minutes. They also have the ability to spill it into Sumo Logic, for example. It's very easy to use."

"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."

"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."

"We like the website protection. It's really good. The dashboard is really simple to use."

"Reblaze has just made things simpler for us."

"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."

Cons

"I think they have failed with their technical support."

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

"The solution could be more user-friendly."

"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."

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

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."

"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."

More Cloudflare cons

"Lacks international presence."

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

"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."

"Juniper is known in our country, but it is not very popular."

"The product must provide more Layer 7 capabilities."

"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."

"It could use support in Spanish."

More Corero cons

"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."

"There is room for improvement in helping us understand session management."

"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."

"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."

"Perhaps the automatic reporting could be better. I would like to have seen more automated reports."

"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."

"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."

Pricing and Cost Advice

"The price of the solution is expensive."

"The product's pricing is minimal compared to other products."

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"The price is reasonable."

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

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

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

"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."

More Cloudflare pricing and cost advice

"The price of Corero is affordable."

"Its price is normal."

"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."

"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."
