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.
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.
Nick Wilsdon - PeerSpot reviewer
An easily scalable and stable product that provides exceptional support
The product should provide improved bot detection and management. The product should also provide support for code management. Everybody working in CDN is currently looking for ways to better manage code deployment with various authorization levels and synchronization with our lower environments. Matching up what's happening in CDN with what's happening on the origin regarding testing would always be useful.

Quotes from Members

Pros

"The tool is user-friendly."
"The solution is stable, and the DNS servers are simple to use."
"Cloudflare has many features."
"I rate its stability a ten out of ten."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"Generally, I am satisfied with this product."
"It is a fast and secure DNS."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"CGNAT is one of its strong areas."
"The customer service is excellent, and I rate it ten out of ten."
"The decryption is great."
"The most valuable feature of F5 BIG-IP AFM is all of my workers enjoy using it."
"Its performance and ease of use are valuable."
"The most valuable feature of F5 BIG-IP AFM is the iRules where I can customize the configuration."
"The most valuable features for me are stability, availability, and security, along with the ability to manage multiple features to secure my applications."
"I find the signature base is very helpful to see traffic"
"Compute@Edge features are valuable to me."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"The product's initial setup phase is straightforward."
"Rate limiting is a good feature that protects from volumetric attacks."
"Its initial setup process is straightforward."
"The product helps our organization to access sites located in different regions quickly."
"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
 

Cons

"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"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."
"Cloudflare should add more documentation and pricing to the cloud version."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"F5 could provide a distributed cloud version."
"Apart from the price, I feel no other areas need improvement."
"NGINX, which F5 purchased, has room for improvement in its features, particularly its load balancing or application load balancing features."
"The initial setup of F5 BIG-IP AFM in a complex environment was simple. However, the full deployment took us approximately one year."
"We needed to protect the database but the solution didn't offer a certain feature to do so."
"Deployment times vary according to the customer. It needs to be heavily configured. You need to look and you need to observe the behavior of the traffic before you can start configuring everything. It can take time."
"The appliance and features could be enhanced further, especially in terms of security. Some features like the WAF firewall may seem expensive compared to the standard license, so there could be room for adjusting the pricing."
"The web gateway feature could improve in F5 BIG-IP Advanced Firewall Manager (AFM)."
"The product should provide improved bot detection and management."
"The solution's pricing could be better."
"Support is not that great."
"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"What I don't like about Fastly is that they charge a heavy price."
"Fastly's customer service area needs improvement."
