Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Björn Lindman - PeerSpot reviewer
The product is highly stable and has valuable features, but it must provide more Layer 7 capabilities
We use the solution for DDoS protection in the routers The DDoS protection features are valuable. The product must provide more Layer 7 capabilities. It must provide deep inspection features. I have been using the solution for ten years. The tool has high stability. I rate the stability a nine…

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

"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"It's very user-friendly."
"Generally, I am satisfied with this product."
"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."
"The solution is very good at mitigating threats."
"Cloudflare has many features."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"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 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 DDoS protection features are valuable."
"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 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 highly resilient product that can handle significantly larger workloads and high volumes of traffic with ease."
"We like the website protection. It's really good. The dashboard is really simple to use."
"Reblaze knows how to manage security. For me as, someone who knows little about security, it's good that I have a firm that optimizes everything according to their standards. It's their responsibility and they are fully hands-on."
"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 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."
"The main feature is using the rules and being able to see the traffic. It helps us find malicious traffic."
"Provides mobile app security."
"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."
 

Cons

"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"There should be a specific price list for enterprise-level customers."
"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"The pricing could be improved."
"Technical support is lacking."
"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."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"It could use support in Spanish."
"The product must provide more Layer 7 capabilities."
"Lacks international presence."
"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."
"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."
"Some of the settings on the dashboard are confusing."
"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."
"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

"I give the price a five out of ten."
"The tool is a premium product, so it is very expensive."
"The price of the solution is expensive."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The product's pricing is minimal compared to other products."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"Its price is normal."
"The price of Corero is affordable."
"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."
