Has helped manage client domains with streamlined access control and threat visibility

I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service. It doesn't pay to try to host your own website.

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 simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."

"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."

"Smaller businesses have seen great ROI due to the low investment and strong performance."

"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."

"Easier http to https redirect using page rules"

"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."

"It is a fast and secure DNS."

"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."

More Cloudflare pros

"Radware Cloud WAF Service is great in terms of blocking unknown threats and attacks; everything seems perfect to me, and I have no complaints or issues regarding the blocking capability."

"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."

"It provides the first level of defense against external threats trying to come into the environment, but it's one of the many toolkits we use."

"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."

"What I appreciate the most about Radware Cloud WAF Service is the API management."

"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."

"What I appreciate most about Radware Cloud WAF Service is that it includes all the aspects that an organization wants to run smoothly, such as overall configuration and real-time protection methods, customization of rule creation, fast deployment, and vital visibility in environment maintenance."

"Radware Cloud WAF Service has reduced our false positive rate by more than 50% and is one of the best tools as we can easily block and reduce our alerts through IP blocking."

More Radware Cloud WAF Service pros

"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."

"The product's most valuable feature is its ability to set up the rules easily."

"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."

Cons

"DNS Management."

"Technical support is lacking."

"In the last two years, there has been a certain amount of downtime when using the VDM."

"The analytics, basically the dashboard, doesn't have much to it."

"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."

"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."

"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."

More Cloudflare cons

"The dashboard of Radware Cloud WAF Service could be more interactive and user-friendly."

"Sometimes, I encounter issues with password reset, particularly in the last two weeks. This indicates some reliability issues or problems within the management interface."

"Radware Cloud WAF Service should provide SSL certificates for its hosting customers."

"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 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."

"In some cases, if the configuration of rules is too strict or complex, there might be a possibility that genuine traffic gets blocked or considered a false positive."

"I would like to see an improvement in the twenty-four-seven support service."

"Regarding zero-day protection, it takes considerable time to update signatures in the Radware Cloud WAF Service."

More Radware Cloud WAF Service cons

"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."

"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."

"The UI is not very intuitive and could be better."

Pricing and Cost Advice

"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."

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"The price of the solution is expensive."

"The tool is a premium product, so it is very expensive."

"The cost primarily depends on the size of the organization."

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"The product's pricing is cheap."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

More Cloudflare pricing and cost advice

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

"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."

"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."

"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."

"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."

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

"The price is a bulk average."
