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.

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…

Displays flexible, user-friendly interface with minor licensing challenges
The product could be improved with a more intuitive interface for complex configurations and more advanced analytics. Additionally, enhanced security features, like a more robust Web Application Firewall, and stronger APIs for better automation would be beneficial. Overall, the main areas for improvement are in strengthening the advanced features to better meet the demands of large-scale enterprise environments. key features for the next release should focus on three areas. First, an enhanced, next-generation security suite with a more powerful Web Application Firewall (WAF) and integrated bot protection. Second, more advanced and customizable analytics dashboards to provide deeper insights into application performance. Finally, greater support for modern, cloud-native environments, including better APIs for automation and seamless hybrid-cloud traffic management

Quotes from Members

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

Pros

"The most valuable feature is the web application firewall."
"The solution provides good load balancing and protection against DDoS attacks."
"Generally, I am satisfied with this product."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"The DDoS protection is the most valuable aspect of the solution."
"It is a good solution. Its vendor support is the most valuable. 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."
"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 DDoS protection features are valuable."
"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."
"This is a hybrid solution."
"From my personal experience, many firewalls provide Load Balancing functionalities, but Kemp Loadmaster has a lot of features and functionalities like what you can configure. So there are a lot of features but we use only five percent of it."
"The pricing of the solution is valuable."
"The most valuable feature is the load balancing and allowing for high availability of our web services."
"The configuration is really easy and the web portal is self-explanatory."
"Edge Security Pack is valuable because of the way it separates between critical infrastructure and the public internet."
"Managing and maintaining multiple servers is done in a single place."
"The user interface is very easy to work with."
"When the templates are used, there is not much left to configure and they just work!"
 

Cons

"Cloudflare could be improved by introducing a mid-tier pricing option."
"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."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"Latencies are always a problem."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"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."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"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."
"It could use support in Spanish."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"The product must provide more Layer 7 capabilities."
"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 would be much easier to have the management interface directly integrate with the Kemp Support library, allowing you to choose the desired template from the online catalog to then directly download to the LoadMaster."
"In the next release, they can introduce 360 views in the same dashboard to make it easier for users to view. The graphical information should be displayed on the dashboard."
"Perhaps Kemp could offer some training videos."
"UI is very basic and unattractive."
"With the license purchase afterwards, if it expires, it begins dropping the HTTP traffic, also the DNS traffic."
"In the web interface, there are a lot of settings in the different menus and it would be helpful if there were an interactive help system or tooltips to help the administrators find and configure the right settings."
"I would like to see more automation and control of overactive and inactive resources. If I could schedule these around our updates then it would be all automated. I would like to set up an automated script to coincide with the scripts I use to update resources and servers."
"The cost of the GEO upgrade is not cost-prohibitive but it's something that would be a nice add-in, out of the box."
 

Pricing and Cost Advice

"The price is reasonable."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"We are using the free version."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as 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."
"The tool is a premium product, so it is very 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."
"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."
"The price of Corero is affordable."
"Its price is normal."
"The Kemp LoadMaster is a tremendous value."
"Any decent product will cost money and if you want great support and a great product, then you will want to spend the money on it."
"The pricing is alright and we pay a monthly licensing fee"
"Nowadays, going with the virtual appliance is the easiest way and the cost is reasonable."
"​I have control on the licensing and all the prices since I work for a partner.​"
"Less expensive than Citrix."
"It has a very attractive ratio of price/performance."
"From a cost perspective, Kemp is very competitive and is not hard to justify by any means."
