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.
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.
Eduardo Oviedo-Blanco - PeerSpot reviewer
A CDN solution to enhance loading times and streamline navigation
When one of the primary nodes spanning from North to South America, from the northern US to the southern US, became operational, it had a big impact. It can be challenging to explain its advantages to clients. The technical nature of the marketing material is too technical for stakeholders. Integrating the solution was straightforward, requiring no extra effort. Edgio Global CDN operates, resembling familiar cloud services but offering elevated functionality. Unlike platforms such as Google Cloud Platform or RIN geared towards development teams, Edgio emphasizes client-facing services that are integral to our operations. Overall, I rate the solution a nine out of ten.

Quotes from Members

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

Pros

"Cloudflare has many features."
"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"The solution is stable, and the DNS servers are simple to use."
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"The most valuable feature is its usability."
"It is a fast and secure DNS."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"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."
"The product's most valuable feature is its ability to set up the rules easily."
"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."
"It's super easy to use and integrate with."
"The product is easy to use and easy to implement."
"The customer support and service responsiveness were excellent."
"The tool's most valuable feature is the Uplynk platform for streaming purposes."
"The Rules Engine V4 is the most valuable feature."
 

Cons

"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."
"The documentation could improve for Cloudflare DNS."
"The analytics, basically the dashboard, doesn't have much to it."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"An integrated SSO feature would be useful for Cloudflare DNS."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"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."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"In the next release, I would like to see more global endpoints for their CDN and a lower price."
"The web interface of the Verizon Edgecast portal is very old. It's not user-friendly, slow, and it is missing some valuable features like the ability to make bulk changes."
"We could not create more than 15 custom rules."
"The tool needs to resolve its lack of innovation."
 

Pricing and Cost Advice

"There are no additional costs beyond the standard licensing fees."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"We don't have any issues with the price."
"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."
"We are using the free tier of the solution."
"A free version of the solution is available."
"The product has an affordable cost."
"Signal Sciences is pretty cheap compared to other solutions."
"The pricing is 50% less than Akamai."
"When I modeled it out, we are spending somewhere between $600 to $800 a month with Verizon EdgeCast."
"The product is cheaper compared to other solutions."
"Be careful about the options because to have all the features can be very expensive."
