Featured Reviews

Mitesh D Patel

Senior Technical Consultant- Cyber Security at Ivalue Infosolution

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.

CIO at a computer software company with 501-1,000 employees

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 most valuable feature of Imperva, in addition to its strong knowledge base, is its effective protection for web applications."

"The solution is scalable."

"The dynamic profiling of websites is the solution's most valuable feature. The security is also good."

"The most valuable features of the Imperva Web Application Firewall are performance and flexibility. We can extend or customize the box itself."

"We can prevent attacks or issues even before they happen."

"The valuable features of Imperva WAF include its effective security breach prevention through automatically updating rules."

"The solution can be configured in just a couple of minutes."

"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."

More Imperva Web Application Firewall pros

"Radware Cloud WAF Service has improved our efficiency by about 95%."

"The API Discovery is also very good because the application is outsourced, which means that we don't have the code. API Discovery allowed me to discover precisely how to orchestrate the API so that I could see the results."

"It has features such as API security that protect against advanced attacks, including business logic attacks. It comes with additional functionalities such as bot protection and AI-driven threat signatures, along with threat intelligence, making it much more than the traditional WAF that we have on-prem."

"The most important aspect of Radware Cloud WAF is that it is over the cloud, offering a comprehensive solution that includes WAF, API protection, bots, and Layer 7 DDoS."

"Geo-blocking is one of the most valuable features we use the most; most of our users are in North, Central, and South America, so we use geo-blocking to block access from other countries."

"DDoS protection is a valuable feature that works efficiently."

"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."

"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."

Cons

"Imperva Web Application Firewall can improve by adding more features to the dashboard. increasing the visibility of the real-time events, besides configuring the administration itself."

"It is complicated to integrate the solution's on-cloud version with other platforms."

"The process to upgrade from one version to another can be a lot simpler than it is currently."

"The user interface could be better."

"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."

"Imperva Web Application Firewall is very expensive."

"Some of the features should be included in the next release is a file integrating monitoring tool. This feature should be improved."

"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."

More Imperva Web Application Firewall cons

"Sometimes, I encounter issues with password reset."

"An area of improvement is the visibility at the attack level."

"Some of the tools are a bit difficult to navigate, and the user interface could be more user-friendly."

"Radware Cloud WAF Service has limited integrations, and I would like to see it integrate with our use of Azure DevOps."

"Alert messages for DDoS attacks or other things take time to reach us, causing delays in our response."

"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."

"Radware does not have much online training available to help customers get the most out of this solution."

"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."

Pricing and Cost Advice

"The tool is expensive."

"The cost of this solution depends on the platform."

"Imperva Web Application Firewall is expensive."

"There are a couple of different licensing models."

"The price of this solution is a little bit high compared to competitors."

More Imperva Web Application Firewall pricing and cost advice

"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."

"For the current market, the price for Radware Cloud WAF Service is exactly where we want it to be."

"We are paying $20,000 annually for six licenses that provide basic WAF functionality."

"When compared to Akamai and F5, Radware's pricing and licensing are highly competitive."

"The pricing is fair. We compared Radware to others using industry reviews and Radware is at the top right now."

"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."

Which is the best DDoS protection solution for a big ISP for monitoring and mitigating?

My recommendation is Imperva.

Is Citrix ADC (formerly Netscaler) the best ADC to use and if not why?

For ADC, any ADC can do a good job. But in case if you want to add WAF functionality to the same ADC hardware you have to look for other ADC's like F5, Imperva, Radware, Fortinet, etc.

DDoS solutions: Any other solutions to consider aside from Radware DDoS Protection Service and F5 Silverline DDoS Protection?

You can have a look to Imperva Cloud WAF, the anti-DDoS mitigation is under 1s and works very well. I observed a lot of DDoS attacks that were well managed (even not seen by the customer) by Imperv...
