Sentiment score
6.1
Radware Cloud WAF Service enhances security, automates tasks, reduces costs, and improves uptime, efficiency, and bandwidth management.
WordPress security can be tricky, and that's where Cloudflare can be absolutely helpful for small businesses.
For the small project I was working on, using the basic tier provided a huge improvement at zero cost.
In terms of return on investment with Cloudflare, it costs my time to set them up, but basically once they're set up, it's done.
They know how much money they are losing while the system is down, so by increasing the possibility of not having a down website or web application, return on investment can be calculated easily.
I wouldn't be able to give a number, but Radware Cloud WAF does save time for our staff due to the automation and excellent detection, which is invaluable.
With our on-prem solution, we spent a lot of time on maintenance tasks, OS updates, and ensuring appliances ran smoothly, but with Cloud WAF, all that is managed by the cloud team, allowing us to focus on alert analysis.
We get major insights from the analytics rules and dashboards, allowing us to pinpoint main issues.

7.2
Imperva's customer service is praised for expertise but criticized for inconsistency, with recent improvements noted by some users.
Sentiment score
7.4
Radware Cloud WAF is praised for quick, knowledgeable support but needs improvements in API support and documentation clarity.
This would help us address issues promptly, especially during unforeseen events like DDoS attacks.
Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model.
I would rate the technical support with Cloudflare as excellent every time I've had to call them.
I would rate the technical support of Imperva DDoS as ten.
On a scale from one to ten, I would rate the technical support that Radware provides for Cloud WAF Service a perfect ten.

Radware Cloud WAF Service excels in scalability, handling traffic surges and diverse industries with seamless integration and high performance.
It is a SaaS tool, but the fact that they have workloads deployed across the world proves that it is a highly scalable tool.
The tool offers very good performance, even during high-traffic periods.
I rate the solution’s scalability an eight out of ten.
99% of customers are using the cloud version of Imperva DDoS protection, so they just purchase the new license and scale as needed.
The scalability of Radware Cloud WAF Service rates as a perfect ten out of ten, as we haven't encountered any scaling issues.
The scalability of the Radware Cloud WAF Service deserves a full ten, as it is definitely scalable.
In terms of scalability, it's also a 10 out of 10 because we are using Radware Cloud WAF Service for more than 60,000 employees in our organization, and it works perfectly fine.

Room For Improvement

Enhancements needed in Cloudflare: analytics, CDN latency, API integration, user support, DNS, pricing, documentation, server coverage, WAF, and cache.
Imperva needs UI improvements, competitive pricing, better integration, real-time analytics, and enhanced support for efficiency and transparency.
Radware Cloud WAF Service faces integration, support, and UI issues; improvements in language support and API management are needed.
There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features.
Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor.
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.
Maybe Imperva DDoS could use endpoints to get information about the attacks before they commence from the endpoint level or establish cooperation with endpoint vendors to share this information.
It would be beneficial if we could perform POST requests and integrate our applications more effectively.
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.
Improving dashboard capabilities to provide this information clearly for management is crucial.
 

Setup Cost

Cloudflare offers scalable pricing, from free to enterprise plans, providing significant value especially for mid-sized companies.
The Imperva platform's pricing is competitive with advanced features, ranging from $5,000 to $10,000 annually and no setup costs.
Radware Cloud WAF is competitively priced with flexible licensing, customizable features, and negotiable terms, appealing to enterprise users.
That's where Cloudflare shines for smaller businesses – it's ten times cheaper than Akamai.
I find it to be cheap.
The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive.
I would rate the pricing of Imperva DDoS as five, where one is very cheap and ten is very expensive.
Pricing could be more competitive, especially for smaller customers.
I find Radware Cloud WAF to be a quite expensive product compared to others.
The pricing is not cheap; it is expensive, but it is effective.
 

Valuable Features

Cloudflare enhances performance and security with CDN caching, DDoS protection, and an easy-to-use dashboard, benefiting many users.
Imperva's platform offers robust security features, user-friendly integration, real-time analytics, and scalability for diverse enterprise protection needs.
Radware Cloud WAF Service offers advanced, AI-enhanced security with Layer 7 defense, DDoS protection, and easy integration for organizations.
The most valuable features of the solution are performance and security.
Techniques like minification and image compression reduce the size of assets, leading to better performance and faster user load times.
The solution has been able to compare it to the market, and I think the product has taken great strides in automating quite a bit of things, and they use a lot of AI.
I have utilized Imperva's Intelligent Traffic Filtering feature. This feature helps me understand how the attack is progressing and what is happening inside the requests to our website.
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 has features such as API security that protect against advanced attacks, including business logic attacks.
The automated analytics for looking at events in Radware Cloud WAF Service are working for us; the automatic event correlation is very beneficial to analyze how the alerts and events occur and visualize the patterns of network traffic and other traffic going in and out from the application via Radware Cloud WAF Service.

Featured Reviews

HA
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.

Solution ensures website availability and proactive threat mitigation
Over the seven years, the most valuable features of Imperva DDoS that I have found are related to DDoS attacks, which are a group of attacks, and not all of them can be resolved on the endpoint level before the website. Using the web firewall before the website is a common use case to protect against malicious requests to the website. I have utilized Imperva's Intelligent Traffic Filtering feature. This feature helps me understand how the attack is progressing and what is happening inside the requests to our website. It allows me to granularly grant or deny access to certain parts of our website. This helps when we know our customers and the types of requests that can be sent from them, enabling us to block some malicious requests. Imperva DDoS has User Behavior Analytics and Threat Intelligence on its board, and this helps us to be protected proactively. Imperva DDoS connects to its database of threats, storing whole information about attacks all over the world in one simple engine. Everyone can use this feature, which can connect to this engine and get information about what is going on at the world level. That is the way to be protected at the company's level. The integration capabilities of Imperva DDoS are very easy and simple. We can run it in 2 hours.

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.
