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.
Bonieber  Orofeo - PeerSpot reviewer
Application gateway optimizes performance and simplifies cloud transitions
There are a lot of things I appreciate about Microsoft Azure Application Gateway. Microsoft Azure Application Gateway is beneficial for us as it helps in publishing our website, providing us comfort when it comes to the availability of our applications. The autoscaling feature in Microsoft Azure Application Gateway is very obvious, and I have no issues with it; it is well planned and organized. Microsoft Azure Application Gateway impacts our cost savings while maintaining higher performance. The Web Application Firewall (WAF) in Microsoft Azure Application Gateway has been very effective in protecting applications from security threats. Microsoft Azure Application Gateway helps us manage our AI-driven applications by enabling faster transactions, improving our work.

Quotes from Members

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

Pros

"It is a fast and secure DNS."
"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."
"Easier http to https redirect using page rules"
"The solution is stable, and the DNS servers are simple to use."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"I rate its stability a ten out of ten."
"The most valuable features of the solution are performance and security."
"The UI is good."
"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."
"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."
"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."
"Imperva is a Gartner leader, so its scalability, performance, and features are excellent."
"There are some features that are configured by default, so even without doing much, it can still provide a level of protection."
"The dynamic profiling of websites is the solution's most valuable feature. The security is also good."
"It has fewer false positives"
"Learning mode and custom policies are helpful features."
"Microsoft has a vast variety of tools, and it blends very well."
"The most valuable feature of Microsoft Azure Application Gateway is its ease of use."
"The solution's integration is very good."
"The simplicity of the solution and its ability to integrate easily with others are its most valuable aspects."
"This is a SaaS product, so it is always up to date."
"The most valuable feature of the solution is traffic management."
"I find Application Gateway’s WAF module valuable because it helps prevent layer 7 attacks."
"The tool helps manage microservices by providing developers with a platform to conduct tests and assessments on the web application. The custom domain option is one of the most valuable features I've found. This feature is incredibly helpful for the end-users of the web application. With the custom domain feature, you can change the lengthy link to a shorter, more memorable one. For example, instead of using a lengthy default link, you can customize it to something like imail.com, which is much easier to remember and share."
 

Cons

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"Latencies are always a problem."
"Support response time could be improved."
"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."
"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."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"The solution could work at being less expensive. It costs a lot to use it."
"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."
"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."
"The process to upgrade from one version to another can be a lot simpler than it is currently."
"The reporting is missing some features, such as: only two export formats, and the time period does not include the last day, week, year."
"I would like the solution to improve its support response time."
"Imperva Web Application Firewall is very expensive."
"I would like to improve the tool's turnaround time in terms of support."
"Imperva Web Application Firewall is a good system, but we found that the visibility of the diverse-path server, e.g. where the traffic is coming from, the different IPs, etc., needs improvement."
"There is nothing specific where the application firewall is falling short."
"One of the challenges we faced was the solution does not support any other PCP protocols apart from HTTP and HTTPS."
"The tool is a pain to deal with when it comes to the area of configuration."
"The solution has many limitations. You cannot upgrade the VPN to the application gateway. So I started with version one, which has limited capabilities, and they provided version two. And unfortunately, I cannot upgrade from v one to v two like other services. So I have to decommission the version one and create a new one with version two. Also the version one was complex with the certificates uploading the SQL certificates."
"The product's performance should be better."
"We have encountered some issues with automatic redirection and cancellation, leading to 502 and 504 gateway errors. So, I experienced some trouble with containers."
"The solution could improve by increasing the performance when doing updates. For example, if I change the certificate it can take 30 minutes. Other vendors do not have this type of problem."
"Application Gateway’s limitation is that the private and the public endpoint cannot use the same port."
"The security of the product could be adjusted."
 

Pricing and Cost Advice

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The cost primarily depends on the size of the organization."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"We are using the free version."
"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 pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"Imperva’s pricing is a bit higher in the market since it offers a full-blown WAF."
"It is a very affordable solution."
"It's an excellent product, but it can be very costly."
"The solution's pricing is an issue."
"The pricing is somewhat expensive. It is actually a huge investment when compared to other countries."
"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."
"The price of Imperva Web Application Firewalls is expensive compared to others."
"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."
"The solution's pricing is not complex. It is not expensive from our point of view."
"We use the tool's basic subscription. Its licensing costs are monthly."
"There is a need to pay a fixed price per month to use the product. There are no additional payments to be made to Microsoft apart from the charges paid towards the monthly licensing costs attached to the solution."
"I rate the pricing seven out of ten because some third-party solutions are even costlier than this."
"The product is expensive. I rate the pricing a seven out of ten."
"The tool's pricing model is pay-as-you-go."
"Microsoft Azure Application Gateway has less price than other application gateway solutions."
"The product is not expensive."
