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.

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

"It's very user-friendly."
"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"Easier http to https redirect using page rules"
"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"The UI is good."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"The stability of the product is good since I haven't had any problems with the solution."
"The dashboard is good and user-friendly."
"Protection is the best solution since it has profile functionality."
"It has threat intelligence and we are using Incapsula. With threat intelligence, we can separate HTTP and HTTPS traffic. We can use Incapsula to send all the threat intelligence to the WAF."
"The solution can scale."
"We have peace of mind that nobody will use malware on us or try to hack our website."
"The three-second service level agreement is already better than the competition."
"It fits our requirements, as well as our budget."
"Helps us to monitor situation in regards to attacks to our sites and prevents a lot of them."
 

Cons

"DNS Management."
"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."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"The solution could be more user-friendly."
"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."
"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."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"The cost could be lower; our end clients need to have a high budget to purchase this solution."
"It should be more user-friendly. Like other web solutions, it would be helpful to be able to easily do policy configuration and identification inside the application. Understanding the in-depth configuration of a policy is somewhat difficult for an engineer, and they can improve that."
"Imperva DDoS does not provide version control."
"We had an issue when securing the web applications for DDoS protection."
"It would be nice to have more security control over mobile applications so I would suggest adding more mobile security features. It would also be beneficial to see improvements in regards to interface bandwidth performance, CPU time, and RAM size. Learning capability of the device is quite weak."
"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."
"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."
"The process to upgrade from one version to another can be a lot simpler than it is currently."
"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."
 

Pricing and Cost Advice

"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."
"The cost primarily depends on the size of the organization."
"The tool is a premium product, so it is very expensive."
"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 solution is expensive when compared to other products but offers unlimited bandwidth."
"We don't have any issues with the price."
"The product's pricing is cheap."
"There are a couple of different licensing models."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
"It is very costly, but the return on investment is very high. Its cost was around $70,000, and we got it back in just six months."
"It is a very affordable solution."
"The solution's price is high for small companies."
"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 cost of this solution depends on the platform."
"​Pricing must be cheaper than the competition and the licensing must be good.​"
