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.
Tanuj-Garg - PeerSpot reviewer
API discovery, bot defense, and DDoS capability optimize application security and development
I see areas in Radware Cloud WAF Service for improvement, specifically in its initial tuning period, because the machine learning model takes two to three weeks for baseline behavior establishment. Closely monitoring alerts during this period is essential to avoid false positives. There's an alert noise issue; during the early stages, we received a high volume of alerts for minor issues, requiring collaboration with the SOC team to fine-tune thresholds and concentrate on genuine threats. The documentation is not up to par, as while the platform's system is robust, the documentation, particularly for API integration, could be more developer-friendly with real-world use cases.

Quotes from Members

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

Pros

"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."
"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"Centralized, full-featured DNS."
"The configurability of the tools and the ease of operation to be the most valuable feature of Imperva."
"The compliance is the most valuable aspect."
"I am impressed with the product's scalability, availability, easy management, and security. We were able to integrate the product with Azure and Sentinel."
"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."
"It has fewer false positives"
"The most important feature I have found to be the ease in how to do the backup and restores."
"The most valuable feature of Imperva, in addition to its strong knowledge base, is its effective protection for web applications."
"It is easy to use and has good security."
"I highly recommend Radware Cloud WAF for its reliability and fast support."
"Radware Cloud WAF Service has improved our efficiency by about 95%."
"With the Radware Cloud WAF Service, we have not faced any incidents in six years."
"My experience with the technical support of Radware Cloud WAF Service is that they are excellent, and I have established a strong relationship with the executive leadership up to Roy, the CEO."
"Cloud WAF's interface is easy to use and protects us from OWASP Top Ten threats. Our dev team do QA checks on applications before they go live, but Cloud WAF creates an additional security layer on our website."
"One of the most valuable features we have found in the solution is protection against attacks from botnet networks and the requests that these remote networks can generate that are blocked from our servers. That frees us from having to deal with that traffic."
"What makes this a comprehensive offering from Radware is that it combines WAF, ADA, bot management, and API protection, which is not currently available from any other provider in the market."
"Importantly, we have not experienced any zero-day attacks because Radware Cloud offers protection against emerging threats."
 

Cons

"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"The documentation could improve for Cloudflare DNS."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"DNS Management."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"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."
"An integrated SSO feature would be useful for Cloudflare DNS."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"If they can bring in generative AI features, that would be useful."
"The user interface could be better."
"Imperva Web Application Firewall is very expensive."
"Imperva Web Application Firewall could improve the console by making it easier to use."
"I would like to improve the tool's turnaround time in terms of support."
"The process to upgrade from one version to another can be a lot simpler than it is currently."
"The support for the on-premises version needs improvement."
"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 see areas in Radware Cloud WAF Service for improvement, specifically in its initial tuning period, because the machine learning model takes two to three weeks for baseline behavior establishment."
"There is a lot more that is expected from Radware's automated analytics for looking at events. There needs to be more context of where protection is required these days."
"Sometimes, I encounter issues with password reset."
"They've changed their process for call logging. I suppose it's fine, but I used to be able to send emails in. They could also build up more local resiliency here in South Africa. They're working on that, so it isn't much of an issue now."
"They have a portal for webinar training but because we are in a Spanish-speaking country, it is difficult for us to watch them. Not all of us are fluent in English, but most of the courses and webinars are in English. That part could be improved..."
"Management often asks for detailed reporting on attacks such as botnet and zero-day attacks, including the number of attacks within a month, week, or day. Improving dashboard capabilities to provide this information clearly for management is crucial."
"The initial setup was complex and took a long time to complete."
"The reporting features could be more intuitive with more real-time monitoring, which would help make faster decisions."
 

Pricing and Cost Advice

"We are using the free version."
"We are using the free tier of the solution."
"That is one of the great features. I was able to access the majority of the features and services for free."
"We don't have any issues with the price."
"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 tool is a premium product, so it is very expensive."
"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 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."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
"The cost of this solution depends on the platform."
"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."
"Imperva Web Application Firewall is expensive."
"It is a very affordable solution."
"The solution's pricing is an issue."
"We are paying $20,000 annually for six licenses that provide basic WAF functionality."
"We are based in El Salvador and don't have a direct license with Radware; we purchase the license through resellers. The pricing is reasonable, as I managed an Akamai product in a previous position, and Cloud WAF is competitively priced."
"The pricing is fair; it's neither particularly cheap nor expensive."
"For the current market, the price for Radware Cloud WAF Service is exactly where we want it to be."
"The pricing is fair."
"Radware Cloud WAF Service falls within a mid-range price bracket compared to other web application firewall solutions."
"If you plan to deploy Cloud WAF, keep in mind that the product is priced based on the megabits of traffic that pass through and the number of transactions. You should get your requirements correct up front. The active attackers feed and CDN services cost extra, so you need to negotiate these features upfront."
"We evaluated other options and, if I remember correctly, one of them was Fortinet, but they didn't seem as effective as Radware. But the price was the biggest difference. Radware had the best price for our type of network and level of scaling."
