Featured Reviews

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…
Pawel Augustyn - PeerSpot reviewer
Provides outstanding resource management and application security across multiple geographies
The most valuable features for me are stability, availability, and security, along with the ability to manage multiple features to secure my applications. The solution also monitors and blocks unconventional requests and maintains security efficiently. The scalability feature also allows me to manage and allocate resources dynamically without disrupting production traffic.

Quotes from Members

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

Pros

"It is a fast and secure DNS."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."
"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"It's very user-friendly."
"Cloudflare has many features."
"From what I've seen so far, there are no negatives to report as of yet"
"The solution offers the flexibility to control configuration rules."
"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. 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."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"The DDoS protection features are valuable."
"This is a hybrid solution."
"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."
"CGNAT is one of its strong areas."
"The solution is very straightforward. The usability is great."
"The setup and functionality are fairly straightforward."
"The features of F5 BIG-IP Advanced Firewall Manager that have proven most effective in securing the network are significant."
"The most valuable feature of this solution is that the blocking of IP's."
"Its performance and ease of use are valuable."
"The product’s most valuable features are LTM and WAF."
"The product helps us provide security validation by protecting various applications from getting hacked."
 

Cons

"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."
"There might be helpful if there was some web application firewall feature."
"The product needs to improve its automation."
"Technical support is lacking."
"Cloudflare's console should be made more user-friendly."
"The documentation could improve for Cloudflare DNS."
"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."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"Lacks international presence."
"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."
"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."
"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."
"F5 should increase its capability to prevent zero-day attacks."
"F5 could provide a distributed cloud version."
"The web gateway feature could improve in F5 BIG-IP Advanced Firewall Manager (AFM)."
"Some spam can go by the firewall."
"NGINX, which F5 purchased, has room for improvement in its features, particularly its load balancing or application load balancing features."
"This would be absolutely the best network security solution if the price were not so high."
"F5 BIG-IP AFM can improve the reporting interface in relation to advanced troubleshooting depending on CLI. They should have enhanced troubleshooting with the use of GUI."
"For configuring the firewall, every single vendor on the planet has pretty much the same logic when it comes to firewalls, and F5 has a completely different approach and completely different behavior."
 

Pricing and Cost Advice

"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 solution is expensive when compared to other products but offers unlimited bandwidth."
"There are no additional costs beyond the standard licensing fees."
"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."
"A free version of the solution is available."
"The price of the solution is expensive."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"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."
"Its price is normal."
"The price of Corero is affordable."
"F5 BIG-IP AFM is an affordable solution. There were not any additional fees other than the standard licensing."
"The price of F5 BIG-IP AFM is a little more expensive than other firewalls on the market."
"It's very expensive, and you pay extra for the models."
"We have purchased a five-year licensing package for the product."
"As per pricing, I would not say cheap, but little higher than cheap, but not very expensive. So you can say kind of value for money solutions."
"The product is expensive."

"F5 BIG-IP Advanced Firewall Manager is not an expensive solution."
