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.
Renato Roque - PeerSpot reviewer
Seamless global application delivery with features like efficient load balancing, web application firewall and robust traffic routing capabilities
I find the WAF policy to be exceptionally valuable as it adds a layer of security protection to our applications. I particularly appreciate its load-balancing capabilities as it allows us to manage multiple instances and support a global presence effectively. From a performance standpoint, users can connect to the Front Door, and the load balancer directs them to the nearest origin location. This aspect has been a key factor in enhancing our user experience with Azure Front Door, making it a scalable solution that positively impacts performance.
Shashank N - PeerSpot reviewer
Provides good stability, but the agent-based approach could be more convenient
The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF. Additionally, the agent-based approach presents challenges with managing agents across versions and dependencies on specific application platforms like Apache or NGINX, leading to compatibility issues and complexity in integration. This agent-based system proved particularly difficult to manage.

Quotes from Members

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

Pros

"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"The most valuable features of the solution are performance and security."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"The solution provides good load balancing and protection against DDoS attacks."
"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."
"Azure Front Door provides DDoS protection and features related to WAF."
"The tool is easy to use for beginners."
"Azure Front Door's advanced routing rules for traffic management are highly effective, allowing you to configure HTTP tags, change different header or header response values, configure origin domains, and add security to your Layer 7 using these routing rules."
"The most valuable feature is that I can have CDN and load-balancing capabilities in a single service instead of managing two separate tools."
"The price is one of the most important aspects of the product. It's quite affordable."
"The solution is good."
"The most valuable feature is that you can implement resources globally. It does not depend on location and ability or something like that. This is to connect clients around the world."
"Rules Engine is a valuable feature."
"Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate."
"The product's most valuable feature is its ability to set up the rules easily."
"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
 

Cons

"An integrated SSO feature would be useful for Cloudflare DNS."
"Latencies are always a problem."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"The pricing could be improved."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"The product's features are limited compared to Cloudflare. The tool also doesn't work well in a hybrid environment. I would like to see a way to add personalized APIs in the system."
"We should be able to use Front Door defenders with multiple cloud vendors. Currently, they can be used only with the Azure cloud. Azure Front Door should also be able to do global load balancing and provide internal front door services. Microsoft should clearly define what Traffic Manager, Application Gateway, and Azure Front Door products do. These are similar products, and people get confused between these products."
"The tool should improve its cost."
"There could be improvements regarding its pricing for large-scale projects."
"The user interface needs improvement as it is difficult to create the mapping to link the problem with your private address sources."
"There's a limitation on the amount of global rules we can add."
"There is room for improvement and they're working on it."
"The product needs to improve its latency."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."
"The UI is not very intuitive and could be better."
 

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 tool is a premium product, so it is very expensive."
"That is one of the great features. I was able to access the majority of the features and services for free."
"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"The cost primarily depends on the size of the organization."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The pricing of the solution is good."
"The solution is a bit expensive."
"It is on a pay-as-you-go basis."
"The product is expensive."
"The transition to the premium tier has led to increased costs, making it more expensive than the classic tier."
"Considering the standard licensing of the tool, even though we have not checked the billing as of now, it might not be very costly."
"The pricing is 50% less than Akamai."
"The product has an affordable cost."
"Signal Sciences is pretty cheap compared to other solutions."
