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.
Mitesh D Patel - PeerSpot reviewer
Effectively defends against threats like cross-site scripting (XSS), SQL injection, and others
It does bring value. For example, consider a BFSI customer. Their application is critical and represents their brand. Without a WAF, an attack could take their application down, harming their reputation. It leads to hampering the customer's workflow. With an Imperva WAF, they protect against attacks like DDoS or SQL injection, ensuring their application remains available and customers are happy. That's the main benefit for both the customer and the organization. The impact depends on the customer's use case. If their business primarily operates online, a CDN is beneficial for traffic optimization. Moreover, the integration options depend on the specific use case of our customers. Generally, integration capabilities are good with SIEM (Security Information and Event Management) parts.
Muhammad ZaheerNazir - PeerSpot reviewer
Helps to handle edge cases and has purge features
I believe Windows Azure CDN can improve monitoring and measuring overall end-user performance. Providing monitoring tools or agents that can be integrated into our pages would be highly beneficial. Setting up a custom domain with Windows Azure CDN involves proving domain ownership, which can take some time. The process is relatively straightforward if your DNS or domain registrar is already integrated with Microsoft. However, the verification process may be more time-consuming if you use a different service provider.

Quotes from Members

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

Pros

"The most valuable feature is its usability."
"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."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"The most valuable feature is the web application firewall."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"Easier http to https redirect using page rules"
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"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."
"Imperva is a Gartner leader, so its scalability, performance, and features are excellent."
"Imperva Web Application Firewall is stable."
"Imperva is easy to use and deploy. The UI is excellent."
"Imperva Incapsula has many valuable features. One, it protects the top 10 OWAS vulnerability, the open web application software platform, this is standard. Secondly, it protects against broken authentication. As well, it has remote execution of code."
"Protection is the best solution since it has profile functionality."
"Technical support was very helpful."
"It's very pretty easy to onboard the URL."
"Its unique interface for managing security performance and ease of use are the most valuable features of this solution."
"The most valuable feature of the solution stems from the fact that one can access Windows Azure CDN from anywhere."
"The fact that it just delivers what it is supposed to do is its most valuable feature...The initial setup is very straightforward."
"The most valuable feature of Windows Azure CDN is its effectiveness."
"One of the most valuable aspects is the capability to store extensive datasets and objects in the cloud, enabling their download through shared access signatures."
"One of the tool's best features is its ability to handle edge cases. For instance, we encountered a situation where we needed to remove certain files from public access. The solution offered a purge feature that allowed us to remove these files. This feature ensured that the files were deleted from all edge servers. Subsequently, we were able to upload new versions of the files."
"The geolocation feature is very important because many colleagues travel worldwide and need to access information from anywhere. The product has improved security."
"The UI is very intuitive."
"I like that CDN offers a routing feature."
 

Cons

"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"An integrated SSO feature would be useful for Cloudflare DNS."
"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."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"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."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."
"There should be a specific price list for enterprise-level customers."
"Sometimes, it takes a bit of time for the technical staff of the solution to get back to our company with a resolution for our problems."
"It would be beneficial to include vulnerability management in the solution, similar to what they have for their on-premise solution."
"The user interface could be better."
"Imperva always needs to adjust to new versions of cyber attacks, it needs to be faster, improve the resiliency of the software of the solution."
"We would like them to hire people in Sweden because it's quite hard when people are sitting in the UK or Belgium because some of the customers really want them to be local."
"I would like to improve the tool's turnaround time in terms of support."
"Its price could be improved. It is quite expensive. It will be good if we could export the configuration. Currently, to control the configuration, we need to go to each website, which is not very convenient."
"I would like to see automated reporting to improve visibility."
"The high price of Windows Azure CDN is an area of concern where improvements can be made."
"Azure is continuously improving its CDN but the documentation should be up-to-date."
"I believe Windows Azure CDN can improve monitoring and measuring overall end-user performance. Providing monitoring tools or agents that can be integrated into our pages would be highly beneficial. Setting up a custom domain with Windows Azure CDN involves proving domain ownership, which can take some time. The process is relatively straightforward if your DNS or domain registrar is already integrated with Microsoft. However, the verification process may be more time-consuming if you use a different service provider."
"The solution’s pricing could be improved."
"Windows Azure CDN should lower its prices."
"We have experienced issues with switch connectivity."
"There were a few bugs that were very disappointing. So, that is a part of the reason why we started using Fastly."
"The response time of the support team must be improved."
 

Pricing and Cost Advice

"We are using the free version."
"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 product's pricing is minimal compared to other products."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"There are no additional costs beyond the standard licensing fees."
"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 pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The price of the solution is expensive."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"It is not expensive compared to the other similar solutions in this category."
"I rate the product price a four on a scale of one to ten, where one is a low price, and ten is a high price."
"The cost of this solution depends on the platform."
"Varies depending on the needs of the customer."
"The tool is expensive."
"Imperva Web Application Firewall's pricing is expensive."
"The price is high compared to other solutions like FortiWeb."
"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a five out of ten."
"The tool's pricing is cheap."
"I rate the price of Windows Azure CDN a six on a scale of one to ten, where one is cheap, and ten is high."
"The pricing of the solution depends on usage and varies based on the company's needs. If you want additional features like advanced logging, it will be pricier. However, it could be cheaper if you don't need those features. It all depends on the resources and requirements."
"It comes at a relatively affordable cost."
"The solution's price depends on how much traffic you have. So, it was okay for us. Payments are to be made on a monthly basis since one has to pay for what they used."
"The solution's price is above the medium range."
"The pricing is extremely high, almost 9 out of 10."
