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.
Yazan Omar - PeerSpot reviewer
An easy-to-use tool with great GUI
The product's initial setup phase was really easy. There is a lot of time involved in the testing phase and other processes related to the area of deployment, so it may take up to two weeks to deploy the solution. The solution is deployed on an on-premises model. One person is enough to take care of the deployment phase of the product. The person involved in the deployment phase needs to better understand topologies when dealing with Fortinet.

Quotes from Members

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

Pros

"The solution automatically detects and responds to certain types of traffic based on geolocation."
"Generally, I am satisfied with this product."
"Cloudflare has many features."
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"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 of Cloudflare DNS is security."
"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 technical support is good."
"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."
"It allows me to see all the traffic on my network."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"We have researched them all, and it's a good solution all around."
"The protection resources and the support are valuable features of the solution."
"The product's initial setup phase was really easy."
"The equipment works very well, and I have not encountered any issues with it."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."
"There are a number of features that are valuable such as the account takeover and various antivirus features."
"It has fewer false positives"
"Imperva DDoS is fairly stable, and its availability is quite high."
"The setup of Imperva DDoS was easy."
"Real-time monitoring is also a great tool, as you may watch several parameters in real time."
"Imperva Web Application Firewall is a highly stable solution and is very mature."
"The most valuable feature of Imperva DDoS is to make our website available for our customers' requests 24 hours a day."
 

Cons

"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"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."
"There might be helpful if there was some web application firewall feature."
"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."
"The documentation could improve for Cloudflare DNS."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"Support response time could be improved."
"I would like to see analytics, big data."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"The solution can be a little more user-friendly and it can be more affordable."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"Alerts and reporting features must be improved."
"The signature updates could be faster. Sometimes we have to upload signatures to the Imperva portal for checking and analysis before we can use them."
"Imperva Web Application Firewall can improve by providing better features, such as improved prevention of zero-day attacks. Additionally, it should include a VR meta-analysis."
"It would be better if we were able to manage and apply changes to multiple websites/web applications, and search WAF logs for multiple websites, via the Incapsula dashboard."
"The solution works for particular zones but isn't always the best solution for all zones."
"Support is one thing I wish Imperva could improve."
"I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one."
"One potential improvement for Imperva is enhancing its alert system."
"The initial setup could be simplified. Every time you have to install the solution you have to get in touch with support or somebody that can to do that for you."
 

Pricing and Cost Advice

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The price is reasonable."
"The price of the solution is expensive."
"A free version of the solution is available."
"We don't have any issues with the price."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The product’s pricing needs improvement."
"It's quite pricey."
"The solution is reasonably priced."
"Make sure you understand the way that Imperva charges. It's very affordable. However, I would like to see a package with the Virtual Patching included. You get to do patching separately."
"There are some licenses that you have to buy to use some features. Its price could be better. Price is always important because, at the end of the day, customers have a budget. If you can meet the budget, you can sell, and if you don't, you cannot sell."
"It's an excellent product, but it can be very costly."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"There is a license for this solution and we purchase the license annually with no additional fees."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
"The cost of this solution depends on the platform."
"The tool's pricing is good."
