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

"The most valuable feature is its usability."
"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 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."
"The UI is good."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"Easier http to https redirect using page rules"
"The most valuable feature is the web application firewall."
"The WAF itself has been very valuable to me because it has such a complete range of features. Another reason why I like it is because it also takes care of the total overview of the traffic over the network."
"Its inline transferring mode is the most valuable because it is 100% transparent. When you change the IP, there is no change on the network side. If you can't and want to try to reach an IP, you can reach the server IP. There are many other advanced security features in it. The smallest appliances of Imperva can handle the highest traffic at a customer site. For example, a smaller appliance from Imperva can provide you the same security as an F5 product."
"The most valuable feature of Imperva, in addition to its strong knowledge base, is its effective protection for web applications."
"There is a quick switch between any of the the nodes if something goes wrong, where there's a there's an attack against a specific area. The security setup is reasonably easy. It's not a problem to do setups and rules and integrations. And, yeah, just the the back end team is also very willing to insist if there's questions that that we cannot answer or with these questions that we do have"
"Imperva Web Application Firewall is a highly stable solution and is very mature."
"The solution is cloud-based and offers us good uptime. It has combined web and API security. Therefore, with one license, you access both application security and also API security."
"Imperva monitors all traffic, even customer access, to the web application. Then, Imperva uses features like signatures to identify attacks like cross-site scripting or SQL injection."
"Imperva is easy to use and deploy. The UI is excellent."
"Available on any device and can be accessed on a wide area network."
"The solution can be configured very granularly and has good control over security."
"Citrix NetScaler offers robust security features, including SmartAccess and customizable policies, making it a reliable choice for safeguarding user data."
"We use the solution's IP Reputation and bot protection features."
"The most valuable feature is the content switching."
"It is the best product out there."
"We have good customer support."
"I find all of it to be valuable, because of the flexibility that is built into this product."
 

Cons

"Technical support is lacking."
"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."
"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"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 could be improved by introducing a mid-tier pricing option."
"The solution could be more user-friendly."
"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 could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"There could be some limitations that from the converged infrastructure perspective: when you want to converge with everything and you want Imperva to get there easily because it's not a cloud component. For example, when you want to build servers and you're using OneView to manage your software-defined networks, implementing Imperva right away is not that simple. But if you're doing just a simple cloud infrastructure with servers in there, you're good to go. Also, we are not able, with Imperva, to block by signatures. Imperva by itself needs to be complemented with another service to do URL filtering."
"I am looking for more data enrichment. We should have the ability to add our own custom data to the system, to the live traffic."
"I don't really use it and therefore can't speak to areas of improvement."
"Imperva Web Application Firewall could improve the console by making it easier to use."
"The Imperva Web Application Firewall automations are good, but there is still room for improvement with them."
"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."
"It's a complicated tool to keep."
"An improvement for Imperva WAF would be to reduce the number of false positives and create more strong use cases based on AI/ML or behavioral analytics."
"In every release - and it doesn't matter if it's a minor release or a major release - they keep moving things around and they keep changing the mechanism. So certain things can work in one version one way, and everything works really well, then when you upgrade it to the next version, it breaks everything because they have a new way of doing it."
"Reducing the overhead required for AppFlow data collection, specifically for HDX Insight, would be a huge improvement."
"It does not have a sandbox cloud service and antivirus. It should have on-prem or cloud sandboxing and antivirus."
"There are some features which are missing.​"
"The tool needs to add a feature where we can access the network policy access manager."
"Citrix should offer a demo or free-trial version of NetScaler. Several other vendors do, but Citrix does not. Pricing should also be more readily available."
"They need to make the solution a little more familiar with easy study guides, learning videos, etc."
"Does not include security. A web application firewall would be a nice addition."
 

Pricing and Cost Advice

"We don't have any issues with the price."
"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."
"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."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The product's pricing is minimal compared to other products."
"The price of the solution is expensive."
"The tool is expensive."
"The price of this solution is a little bit high compared to competitors."
"Everybody complains about the price of this solution."
"There are a couple of different licensing models."
"Imperva Web Application Firewall's pricing is expensive."
"The solution's pricing is an issue."
"The price is high compared to other solutions like FortiWeb."
"It is a very affordable solution."
"The solution is expensive compared to one of its competitors."
"I give the price of the solution a seven out of ten."
"Citrix Web App and API Protection are in the middle when we talk about pricing and licensing"
"Its licensing cost is much higher than other products, but it is acceptable because it is a one-time investment, and we are getting our requirements fulfilled when we buy this product. So, there is no issue with the pricing."
"For partners, NetScaler is not as expensive price-wise versus F5."
"The licensing costs for this solution vary depending on which model is being used."
"Citrix NetScaler's pricing is slightly above average but not overly expensive. I would consider F5 BIG IP to be the most expensive, Citrix NetScaler to be the second most expensive, and then Kemp Load Balancer to be the third."
"Its price is comparable to others and affordable."
