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

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."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"The most valuable features of the solution are performance and security."
"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."
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"The solution is very good at mitigating threats."
"The most valuable feature is its usability."
"The most valuable feature of F5 BIG-IP AFM is the iRules where I can customize the configuration."
"The features of F5 BIG-IP Advanced Firewall Manager that have proven most effective in securing the network are significant."
"The product’s most valuable features are LTM and WAF."
"The protection is very useful."
"The most valuable feature of F5 BIG-IP AFM is all of my workers enjoy using it."
"The most valuable features of F5 BIG-IP Advanced Firewall Manager (AFM) are the web gateway, load balancing, services, and applications available."
"The solution is easily deployable and has great functionality."
"We use the solution for load balancing and WAF (web application firewall)."
"Rate limiting is a good feature that protects from volumetric attacks."
"The product's initial setup phase is straightforward."
"Its initial setup process is straightforward."
"The product helps our organization to access sites located in different regions quickly."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"Compute@Edge features are valuable to me."
"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

"Support response time could be improved."
"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."
"An integrated SSO feature would be useful for Cloudflare DNS."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"The documentation could improve for Cloudflare DNS."
"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"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."
"NGINX, which F5 purchased, has room for improvement in its features, particularly its load balancing or application load balancing features."
"The solution doesn't really meet our requirements for an edge firewall."
"The initial setup of F5 BIG-IP AFM in a complex environment was simple. However, the full deployment took us approximately one year."
"The solution’s initial setup is not easy."
"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."
"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."
"It doesn't compare to next generation firewalls"
"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."
"The solution's pricing could be better."
"The product should provide improved bot detection and management."
"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."
 

Pricing and Cost Advice

"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."
"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."
"A free version of the solution is available."
"I give the price a five out of ten."
"We don't have any issues with the price."
"That is one of the great features. I was able to access the majority of the features and services for free."
"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."
"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."
"F5 BIG-IP Advanced Firewall Manager (AFM) is an expensive solution. They are one of the best in the market, but the price could be cheaper."
"We have purchased a five-year licensing package for the product."
"F5 BIG-IP Advanced Firewall Manager is not an expensive solution."
"The product is expensive."
"It is somewhat on the expensive side although it is worth the additional cost."
"F5 BIG-IP AFM is an affordable solution. There were not any additional fees other than the standard licensing."
"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 price of F5 BIG-IP AFM is a little more expensive than other firewalls on the market."
"The solution is cheaper than other products in the market."
"Fastly is less expensive than one of its competitors."
"It is an expensive solution."
"The pricing has been very competitive."
