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.

Provide DDoS protection and better security at effective rate
It is expanding its number of data centers for scrubbing traffic. Currently, there is only one POP for cleaning in South Africa. They might add another POP in North Africa, possibly in Nigeria or Egypt. Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning. Increasing the number of POPs across the continent would help address these latency issues and improve overall service. While the platform is already quite strong, there’s always room for improvement, especially in keeping up with emerging trends and new types of attacks. Enhancing security capabilities could be beneficial. Integrating more advanced AI features could significantly improve its effectiveness and help customers leverage these tools more effectively. It would be great to see more focus on AI integration to handle and analyze data more efficiently.

Quotes from Members

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

Pros

"New and innovative way to protect the client's data."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"Centralized, full-featured DNS."
"The most valuable feature is the web application firewall."
"The solution offers the flexibility to control configuration rules."
"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."
"The tool is user-friendly."
"The most valuable features of the solution are performance and security."
"It is a user-friendly product in terms of monitoring and updating policies."
"The product's initial setup phase was really easy."
"The protection resources and the support are valuable features of the solution."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"The equipment works very well, and I have not encountered any issues with it."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"It allows me to see all the traffic on my network."
"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 blocks all types of attacks."
"​Technical support provides good, quick responses."
"Real-time monitoring is also a great tool, as you may watch several parameters in real time."
"The solution's most valuable aspect is that it is easy to configure."
"The solution has a very good interface."
"The dashboard is good and user-friendly."
"Technical support was very helpful."
"It is an effective threat mitigation tool."
 

Cons

"There might be helpful if there was some web application firewall feature."
"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"Support response time could be improved."
"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."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"Alerts and reporting features must be improved."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The web interface could be much better."
"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The product’s pricing needs improvement."
"Certificate management could be improved."
"It would be beneficial to include vulnerability management in the solution, similar to what they have for their on-premise solution."
"The product could use a broader scope in the area of policies."
"We faced issues regarding compliance with client procedures. The client had strict compliance rules, and Imperva needed to be on a VM, while the client required containerization, causing a conflict. They went with Imperva for the on-premise version but shelved the cloud project due to too many blockers."
"It's quite expensive."
"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 needs to improve Integration with third parties for their on-prem deployment models. The integration is not that good yet."
"The cost could be lower; our end clients need to have a high budget to purchase this solution."
 

Pricing and Cost Advice

"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 price of the solution is expensive."
"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"The price is reasonable."
"That is one of the great features. I was able to access the majority of the features and services for free."
"There are no additional costs beyond the standard licensing fees."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The product’s pricing needs improvement."
"It's quite pricey."
"The solution is reasonably priced."
"We are satisfied with the pricing."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"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 license is on a yearly basis."
"It is a very expensive solution. The price is very high. A lot of customers tell us that they would love to use Imperva more. I have some customers who have 50 websites, but they have only 10 websites on Imperva because of the price. They would love to have all their websites running through Imperva, but they can't. They have to choose the more critical websites to protect because the price is very high. It is a very good product, but it is too expensive. If you buy a plan for 20 megabytes and you don't consume all of your 20 megabytes, it is okay, but if you consume more, you are charged for the superior traffic."
"The data packages are higher than our needs so we end up paying for data that we don't use."
"The solution's price is high for small companies."
