Has significantly improved threat visibility and reduced false positives through intelligent bot detection and real-time analysis
The best features of Radware Cloud WAF Service that I prefer most include the bot protection. Its deployment was very smooth and flexible when I started deploying it. The reporting and visibility feature of the Bot Manager are noteworthy, as the dashboard gives clear insight into the traffic, activity, and block threats. The AI threat intelligence feature is quite impressive. In terms of blocking unknown threats and attacks, I assess Radware Cloud WAF Service as quite impressive; if I have to rate it out of 10, I would rate it eight and a half. The automated analytics for looking at events with Radware Cloud WAF Service is generally fine, and whenever we use it, it gives almost perfect results. In API protection with Radware Cloud WAF Service, we have multiple applications that we are using currently, and whenever there is any threat related to an API, it helps us provide detailed insight. Additionally, whenever there is unusual API traffic, it helps us monitor and detect threats.

Room for improvement with user interface while competitive pricing impresses
It is managed through Infrastructure as Code, so all configurations can be managed in the code itself, which is beneficial. Because it uses rules, it is easy to set up, and we have many different sites where the configurations are straightforward. Though the UI is not very interactive, which is a downside, we can manage many things. The UI is not very intuitive and could be better. However, we manage all the configurations through code, which is easy to maintain. It has extensive anomaly detection capabilities, so the traffic is classified into several categories where thresholds can be defined and customized based on false positives and false negatives. This is advantageous because you do not need to tweak it very often. Once you set it up, an audit once a quarter would suffice. Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate.

Quotes from Members

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

Pros

"The Bot Manager operates on the concept of AI/ML and is essential for our security strategy."
"Radware Cloud WAF Service has positively impacted our organization by giving us peace of mind with suspicious traffic, fewer web security concerns on public services, and more confidence in the protection of our applications."
"I am currently satisfied with Radware Cloud WAF Service because it is a great tool to protect Layer 7 applications."
"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 isolation feature is the most important one because everything is going directly to Radware first and then it goes into our system. What we get is the filtered version of everything that would otherwise come directly to us."
"The interface is quite concise and clear, and it is easy to navigate."
"Radware Cloud WAF Service has positively impacted my organization by providing peace of mind for the team and regulatory compliance, since having the application properly protected meets our banking field requirements."
"Radware Cloud WAF Service is very top-notch and we in the banking institution are happy with it."
"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."
"Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate."
"The product's most valuable feature is its ability to set up the rules easily."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
 

Cons

"Sometimes, I encounter issues with password reset, particularly in the last two weeks. This indicates some reliability issues or problems within the management interface."
"We've had some issues with putting certificates in."
"The dashboard needs improvement as some users find it complex."
"The reporting features could be more intuitive with more real-time monitoring, which would help make faster decisions."
"The area that can improve with Radware Cloud WAF Service is the speed at which they block geo-fencing and IP for P1 cases, which currently takes about an hour. If they could reduce that to ten to 15 minutes, it would be easier for us."
"The Cloud Portal has room for improvement."
"I'm not sure about how much historical traffic data we can access. Knowing the ability to view traffic from six months back would be beneficial for audit and compliance purposes, especially if an attack happens on an application."
"Although I don't consider it to have significant downsides, I believe the UI could be improved to be more user-friendly, especially for new joiners in SOC who might struggle to understand the traffic based on numerical data."
"The UI is not very intuitive and could be better."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
