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.
DEMİRHAN ÇAVUŞOĞLU - PeerSpot reviewer
A tool for centralized management including inventory and sales tracking
Citrix ADM has the ability to implement policies to tighten security. For instance, you can restrict access to your network from outsiders or lack necessary security measures such as antivirus programs. Additionally, there's the Delivery Controller, which allows for comprehensive monitoring and management tasks such as remote restarts, maintenance, and registration. Another essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently.

Quotes from Members

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

Pros

"Centralized, full-featured DNS."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"It is a fast and secure DNS."
"The most valuable feature of Cloudflare DNS is security."
"The solution can scale."
"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."
"The configurability of the tools and the ease of operation to be the most valuable feature of Imperva."
"Very intuitive and granular configuration - It does not require much time, or advanced knowledge, for configuration and maintenance."
"Imperva WAF's strongest features are the detection of web application threats and vulnerabilities in the source code."
"It has fewer false positives"
"The solution is very scalable. It is one of the most important features. You can also expand resources and features as well."
"The compliance is the most valuable aspect."
"The flexibility in configuration options is impressive."
"For NetScaler, our major use cases are database load balancing, PowerVPN VPN access gateway, WAF (Web Application Firewall), and content switching."
"The advantage of Citrix Web App and API Protection is just its graphic user interface for beginners. The solution is nothing special, but we have to use it for the corporation. Another advantage of Citrix Web App and API Protection is that we have our copy to test things and get the know-how of it."
"Helped us a lot with load balancing."
"Citrix NetScaler offers robust security features, including SmartAccess and customizable policies, making it a reliable choice for safeguarding user data."
"One of the most beneficial features for application delivery is its integration with Citrix Storefront, facilitating user logins and ensuring continuity during data center outages."
"Manageability and visibility are good."
"NetScaler Gateway: Why? Availability/Security: We delivered more than 200 applications thru Xenapp. This feature give us the possibility to deliver the applications anywhere. Currently, 30% of access is made through our NetScaler Gateway (Internet connections)."
 

Cons

"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"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."
"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"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."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."
"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."
"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."
"It's a complicated tool to keep."
"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."
"They can provide an option to create reports, automatically import the entire report, and create rules again. In a real-life crisis, it would be helpful to be able to import a report and generate security rules from that report. I should be able to create a simple query and import the reports automatically. It can maybe also tell us the format of the report."
"It is complicated to integrate the solution's on-cloud version with other platforms."
"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."
"The solution works for particular zones but isn't always the best solution for all zones."
"The support for the on-premises version needs improvement."
"Security could be improved because then I can get rid of my Cisco firewalls. If they improve the security then I could run my security, my proxy, my firewalling and my SDN solution on one device instead of having to have multiple devices."
"Citrix Web App and API Protection could improve in the area of licensing"
"Finding relevant documentation for learning NetScaler can be challenging, especially for beginners who prefer a web interface over command-line interfaces."
"The technical support has room for improvement."
"The setup for Citrix NetScaler has room for improvement. It could be easier."
"The user interface could be more friendly. Some wizards and other documentation for administrators, as well as some use cases, helps us to understand the solution."
"The configuration for its web application firewall is complicated."
"I would like to enhance the solution's bot protection features."
 

Pricing and Cost Advice

"We don't have any issues with the price."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The price is reasonable."
"The product's pricing is minimal compared to other products."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"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 price of this solution is a little bit high compared to competitors."
"The tool is expensive."
"There are a couple of different licensing models."
"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."
"Imperva Web Application Firewall is expensive."
"It is a very affordable solution."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"The pricing is somewhat expensive. It is actually a huge investment when compared to other countries."
"The solution is expensive compared to one of its competitors."
"You can do CapEx and then a yearly monthly fee, or you can do a subscription model, whether that's one month, month-to-month, or three-year subscription model."
"We have all the features and functions of Citrix because we have a premium license."
"It is true that it is a bit pricey compared to newer technologies coming to the market. For example, A10 is a load balancer that does everything that Citrix can and it does a lot more than what NetScaler does when it comes to the security space, and their prices are so cheap. Every box comes with its own license and support built into it. When you compare that with NetScaler, you have to buy licenses separately, you have to buy a support agreement that is going to be separate. A small NetScaler, even if it is a VPX which is a virtual server, could cost you close to $150,000 to $200,000 dollars. So the pricing is really high."
"F5 BIG-IP is much more expensive than Citrix ADC. For example, If we choose two platforms, Citrix ADC, 3000 version, and we choose F5, F4200 version. F5 BIG-IP has connections, timers, and throughput similar to Citrix ADC, but the price is very expensive."
"This product is more expensive than some of the competitors."
"The tool is cheap."
"The solution's pricing is very high compared to its competitors."
