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.
IshtiaqKhalil - PeerSpot reviewer
Displays flexible, user-friendly interface with minor licensing challenges
The product could be improved with a more intuitive interface for complex configurations and more advanced analytics. Additionally, enhanced security features, like a more robust Web Application Firewall, and stronger APIs for better automation would be beneficial. Overall, the main areas for improvement are in strengthening the advanced features to better meet the demands of large-scale enterprise environments. key features for the next release should focus on three areas. First, an enhanced, next-generation security suite with a more powerful Web Application Firewall (WAF) and integrated bot protection. Second, more advanced and customizable analytics dashboards to provide deeper insights into application performance. Finally, greater support for modern, cloud-native environments, including better APIs for automation and seamless hybrid-cloud traffic management
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 web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"I like Cloudflare's application gateway and DDoS protection."
"The solution provides good load balancing and protection against DDoS attacks."
"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."
"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."
"The DDoS protection is the most valuable aspect of the solution."
"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."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"It has greatly fortified the performance and uptime of our front-door email ingress, simplified and segmented mail routing, and reduced admin overhead for mail issue resolution and troubleshooting."
"Managing and maintaining multiple servers is done in a single place."
"​Simple to install with good documentation."
"With Kemp 360 Central, our customers get a nice overview of their Kemp products and an easy way to upgrade firmware on all devices from a single interface."
"The security features are the most valuable features of this solution."
"It helps with efficiency and reactivity, in case of assistance needs."
"LoadMaster is easy to deploy and understand."
"The configuration is really easy and the web portal is self-explanatory."
"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."
"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."
"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

"The solution could be more user-friendly."
"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."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"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."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"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."
"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."
"Some documentation is out of date versus the new version, and things have been moved​."
"The ability to see live traffic is not great and can be improved."
"Some of the support documentation seems to make assumptions that the person installing or configuring is experienced with the product or concepts."
"We experienced a brief period of instability."
"Although Kemp is very user-friendly, it lacks a more custom configuration."
"It would be helpful if there were a way to incorporate tooltips on the fields so that we don't have to dig through documentation."
"In the next release, they can introduce 360 views in the same dashboard to make it easier for users to view. The graphical information should be displayed on the dashboard."
"To make it a perfect ten out of ten it would need better connection logging. If there is an active connection, that there is better logging. It should also have better management monitoring tools."
"The UI is not very intuitive and could be better."
"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."
"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."
 

Pricing and Cost Advice

"The price of the solution is expensive."
"We don't have any issues with the price."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The tool is a premium product, so it is very expensive."
"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."
"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."
"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."
"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."
"Licensing is yearly and I am going to guess that it is CAN $2000.00."
"The Kemp LoadMaster is a tremendous value."
"​I have control on the licensing and all the prices since I work for a partner.​"
"The costs for the Kemp Load Balancer solution are okay because, for a good product, you have to spend money."
"Currently, no cost is involved with a virtual load balancer. They have used open source. We did not pay for software. We paid for the expertise. We are only paying the consulting charges, which are very reasonable, that is, around a thousand dollars."
"The license varies according to the number of megabits."
"It is well-priced and licensing is very flexible."
"Download Kemp's VLM trial and take it for a test drive; you will be impressed."
"Signal Sciences is pretty cheap compared to other solutions."
"The product has an affordable cost."
"The pricing is 50% less than Akamai."
