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

"Easier http to https redirect using page rules"
"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 most valuable features of the solution are performance and security."
"The technical support is good."
"New and innovative way to protect the client's data."
"The solution provides good load balancing and protection against DDoS attacks."
"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"Configuration for different application sources is most valuable. We can segregate the traffic that an application is carrying and identify the sizing in Imperva."
"It mitigates all of the availabilities of risks around web applications."
"The solution is very scalable. It is one of the most important features. You can also expand resources and features as well."
"The most valuable features of the Imperva Web Application Firewall are performance and flexibility. We can extend or customize the box itself."
"There are a number of features that are valuable such as the account takeover and various antivirus features."
"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."
"We can prevent attacks or issues even before they happen."
"Protection is the best solution since it has profile functionality."
"From a financial point of view, we no longer need to appropriate more horsepower to our backend web servers constantly to service these requests because Cloud WAF is preventing malicious bots from accessing our web page. It reduced the load on our backend."
"No valuable quote was provided in the review."
"I like the reliability of the system since it's quite reliable."
"The most valuable feature of Radware Cloud WAF Service is the visibility into attacks that are being cut off instantly."
"The solution offers good protection."
"With the Radware Cloud WAF Service, we have not faced any incidents in six years."
"The solution requires very little maintenance; we install it, it works without any problems, is reliable, and we can almost forget about it."
"I like that Cloud WAF provides me with lots of information. All the events and all the possible attacks appear in front of you, and false positives appear through different channels."
 

Cons

"Latencies are always a problem."
"The product needs to improve its automation."
"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."
"There should be a specific price list for enterprise-level customers."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"An integrated SSO feature would be useful for Cloudflare DNS."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"It would be useful if the solution used more intelligence in attack protection. For example, firewalls are to be dependent on the configuration, but if they could have some data science around it the solution would be even better. The profiling of the traffic, and making decisions surrounding that should be intelligence-based, instead of being based on the configuration of the firewall itself."
"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 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."
"Some of the features should be included in the next release is a file integrating monitoring tool. This feature should be improved."
"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."
"In the past, I have bugs on the WAF. I've contacted Imperva about them. Future releases should be less buggy."
"Sometimes our web application firewall will slow down."
"I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one."
"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."
"I would like to see an improvement in the twenty-four-seven support service."
"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."
"We receive many reports from our security team of IPs flagged by our security tools, such as Palo Alto. I cannot add the file containing the IPs to get them blocked; instead, I have to contact Radware support and open a ticket for them to do it. I need to be able to block flagged IPs myself, as it currently takes more time to open a ticket, contact the support team, and wait four to six hours for a response. I want to be able to upload a file with 2,000-3,000 IPs in the console and then apply and save the configuration."
"If we want to publish services to a limited number of providers and we only want those providers to connect, we need to forward those requests to the Radware support team and they apply them, but it takes some time."
"The lower-level technical team at Radware could improve their approach to problem-solving as they sometimes are very slow."
"Alert messages for DDoS attacks or other things take time to reach us, causing delays in our response."
 

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."
"A free version of the solution is available."
"The cost primarily depends on the size of the organization."
"The price of the solution is expensive."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"We are using the free tier of the solution."
"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."
"I give the price a five out of ten."
"It's an excellent product, but it can be very costly."
"The solution's pricing is an issue."
"Imperva Web Application Firewall price is higher compared to other solutions. However, everything is included in the price."
"Imperva Web Application Firewall's pricing is expensive."
"There is a license for this solution and we purchase the license annually with no additional fees."
"We sell three-year licenses for Imperva Web Application Firewall to our customers. The price is a little expensive."
"The price of this solution is a little bit high compared to competitors."
"The tool is expensive."
"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."
"The pricing is fair; it's neither particularly cheap nor expensive."
"I am not directly involved in pricing and setup cost discussions, but it seems that Radware offers a more cost-effective solution compared to F5. It is considered a good value for our budget."
"Radware Cloud WAF Service falls within a mid-range price bracket compared to other web application firewall solutions."
"The pricing is fair. We compared Radware to others using industry reviews and Radware is at the top right now."
"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."
"I believe the prices are fair."
