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.

Enhanced network security with effective threat filtering and good bot managing features
We use Imperva DDoS protection to safeguard our network from multiple attacks. It is especially useful to protect websites or applications by redirecting traffic to eliminate threats Imperva DDoS increases our uptime to 99.99% by filtering and managing traffic to ensure only genuine traffic…

Helps us to monitor attacks to our sites and prevents a lot of them
Set up Wallarm as a reverse proxy. Do not replace your web server. Use Wallarm first in monitoring mode, then learn from Wallarm which type of request is false positive and which type of request is not. This process takes a couple of weeks for very highly-loaded web applications (few millions of unique visitors in one month). Then you can turn Wallarm into blocking mode and everything will be fine. Do not forget to build a monitoring system, the wave, and API for it. Before we started using Wallarm, I already knew Ivan (CEO) and Stepan (COO) from a couple of years before. Ivan had his own security company and Stepan was working on a Russian security magazine called Xakep. They told us that they wanted to create a new WAF and already had a working version of it. They asked me to test it. We did tests, and it was really good. After few month after testing, we signed an agreement. Our choice was made not because we knew these guys for a long time, but because the product was really cool and we were glad to start using it as one of the first on the market!

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 of Cloudflare DNS is its global reach and it is always evolving."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."
"It is a fast and secure DNS."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"Cloudflare has many features."
"The three-second service level agreement is already better than the competition."
"The complete solution is valuable for everything it delivers and the protection it offers."
"It is a stable solution."
"Data masking is the most valuable feature of this solution."
"The solution is very scalable. It is one of the most important features. You can also expand resources and features as well."
"The configurability of the tools and the ease of operation to be the most valuable feature of Imperva."
"There are many features. There is ease of deployment. You can deploy the Imperva Web Application Firewall in two to three minutes. After that, you have to set the policies. For setting policies, you have toggle buttons. You can turn something on or off."
"The solution is scalable."
"Helps us to monitor situation in regards to attacks to our sites and prevents a lot of them."
 

Cons

"The pricing could be improved."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"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."
"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."
"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."
"Support response time could be improved."
"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."
"It would be beneficial to include vulnerability management in the solution, similar to what they have for their on-premise solution."
"Sometimes, support tickets don't get addressed quickly."
"There is nothing specific where the application firewall is falling short."
"The rules surrounding the making of web applications could be improved."
"The user interface could be better."
"In the past, I have bugs on the WAF. I've contacted Imperva about them. Future releases should be less buggy."
"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."
"I am looking for more data enrichment. We should have the ability to add our own custom data to the system, to the live traffic."
"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."
 

Pricing and Cost Advice

"The product's pricing is cheap."
"The product's pricing is minimal compared to other products."
