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.
SayedAbdelrhman - PeerSpot reviewer
Provide bot protection and has proficient documentation
During our discussion with the internal Microsoft team about assessing our environment, they confirmed that we have sufficient security measures, especially regarding edge protection. Internally, we believe we are now certified. In the future, we could consider adding layer four protection from the firewall. Front Door combines CDN and WAF protection, so further enhancing its features could benefit both the customer and us. We monitor the number of users attempting to access our IP or DNS servers. When designing the system, we initially needed to ensure our environment was protected with a WAF. However, WAF is currently too costly for us, so we created private links and connected them to Front Door. Overall, I rate the solution an eight out of ten.
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

"From what I've seen so far, there are no negatives to report as of yet"
"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."
"The UI is good."
"The most valuable features of the solution are performance and security."
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"It is a fast and secure DNS."
"The tool is user-friendly."
"It inspects the traffic at the network level before it comes into Azure. We can do SSL offloading, and it can detect abnormalities before the traffic comes into the application. It can be used globally and is easy to set up. It is also quite stable and scalable."
"You can assign as many web application firewall policies as you want to the same instance of Front Door."
"Azure Front Door provides DDoS protection and features related to WAF."
"The web application firewall is a great feature."
"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."
"Has a great application firewall and we like the security."
"I find the technical support excellent, and I rate it a ten."
"Azure Front Door provides DDoS protection and features related to WAF."
"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."
"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."
 

Cons

"The pricing could be improved."
"Technical support is lacking."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"There might be helpful if there was some web application firewall feature."
"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 support needs to be accessible from more places, a wider area of coverage."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"I dislike the URL set parameters."
"The product needs to improve its latency."
"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."
"There could be improvements regarding its pricing for large-scale projects."
"There could be improvements regarding its pricing for large-scale projects."
"There is room for improvement and they're working on it."
"It lacks sufficient functionality."
"The user interface needs improvement as it is difficult to create the mapping to link the problem with your private address sources."
"The UI is not very intuitive and could be better."
"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."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
 

Pricing and Cost Advice

"We are using the free tier of the solution."
"I give the price a five out of ten."
"The product's pricing is minimal compared to other products."
"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."
"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."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"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."
"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 pricing of the solution is good."
"The product is expensive."
"The solution is a bit 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."
"It is on a pay-as-you-go basis."
"The product has an affordable cost."
"The pricing is 50% less than Akamai."
"Signal Sciences is pretty cheap compared to other solutions."
