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

ROI

Sentiment score
6.5
Cloudflare enhanced speed, security, and data protection, providing significant ROI and improved operations and client satisfaction for businesses.
Sentiment score
6.3
Imperva DDoS ROI is complex, influenced by compliance, mitigation, cost savings, and service availability, enhancing financial efficiencies.
Sentiment score
8.1
Radware Cloud WAF Service boosts ROI through enhanced security, reduced costs, minimized risks, and increased operational efficiency.
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.
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.
Radware Cloud WAF has helped reduce false positives and efforts, which in turn, improved the total cost of ownership by freeing up time to focus on other projects.
 

Customer Service

Sentiment score
7.0
Cloudflare's customer service is efficient for paying users, but responses can vary in speed and effectiveness for others.
Sentiment score
7.2
Imperva DDoS support receives mixed reviews but is praised for fast resolutions, 24/7 availability, and improved quality.
Sentiment score
7.9
Radware Cloud WAF Service excels in responsive, knowledgeable support, though clients seek extended service for faster issue resolutions.
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.
The key factor is the language in which the support is offered, which, in this case, is in Thai.
I would rate the technical support of Imperva DDoS as ten.
The support provided by Radware's Emergency Response Team is excellent.
We have ERT premium support with a five-minute SLA.
They are usually very fast in response.
 

Scalability Issues

Sentiment score
8.1
Cloudflare is praised for seamless scalability, managing enterprise-level traffic efficiently and earning high customer satisfaction during peak events.
Sentiment score
7.9
Imperva DDoS efficiently scales in cloud environments, though licensing costs and transitions from on-premise can pose challenges.
Sentiment score
8.3
Radware Cloud WAF Service offers seamless scalability and integration, effectively handling high traffic for diverse global applications.
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.
Since it's a Cloud WAF, it is always scalable.
I would rate it nine out of ten in terms of handling the capacity and volume.
 

Stability Issues

Sentiment score
7.6
Cloudflare is widely regarded as stable and reliable, with improvements noted in uptime and performance on higher plans.
Sentiment score
7.8
Imperva DDoS is highly stable with few incidents, rated 8-9 for performance despite occasional cloud-related content delivery issues.
Sentiment score
8.2
Radware Cloud WAF Service is highly stable and reliable, with minor past issues that have been mostly resolved.
For DDoS protection, I would not recommend Cloudflare.
I rate the solution’s stability an eight out of ten.
The service is very stable with no impacts during high-traffic periods.
The stability of Imperva DDoS is very good, as it seems they have a lot of servers around the world.
I have never encountered downtime, maintenance-related issues, or latency.
The stability of Radware Cloud WAF Service is excellent, and I would rate it as a ten.
There have been no issues with downtime, bugs, or glitches.
 

Room For Improvement

Cloudflare requires improvements in analytics, CDN speed, API, technical support, DNS management, documentation, pricing clarity, and international and reseller support.
Imperva DDoS needs interface improvements, reliable support, pricing transparency, enhanced features, and better global integration for reduced latency.
Radware Cloud WAF Service needs improvements in integration, UI, reporting, support, licensing, scalability, and tool integration for performance enhancement.
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.
Cloudflare should add more documentation and pricing to the cloud version.
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 cost-effective, scalable plans with no setup fees, starting from free for small businesses to enterprise-level solutions.
Enterprise users find Imperva DDoS competitive, with zero setup costs; prices range $200-$10,000/month, offering valuable protection.
Radware Cloud WAF Service offers mid-range pricing with modular licensing, extra feature costs, and negotiation flexibility for enterprises.
That's where Cloudflare shines for smaller businesses – it's ten times cheaper than Akamai.
I find it to be cheap.
I think they should consider reevaluating the pricing for support, as it can be quite high.
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 security, speed, and SEO with easy-to-use features like CDN, SSL, DDoS protection, and centralized management.
Imperva DDoS provides robust, cloud-based security with ease of use, real-time monitoring, and comprehensive protection against attacks.
Radware Cloud WAF offers robust Layer 7 protection with advanced features like bot management, DDoS defense, and user-friendly management.
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.
Radware Cloud has significantly reduced attacks on our applications.

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.
DerrickAkankwasa - PeerSpot reviewer
Provide DDoS protection and better security at effective rate
It is expanding its number of data centers for scrubbing traffic. Currently, there is only one POP for cleaning in South Africa. They might add another POP in North Africa, possibly in Nigeria or Egypt. Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning. Increasing the number of POPs across the continent would help address these latency issues and improve overall service. While the platform is already quite strong, there’s always room for improvement, especially in keeping up with emerging trends and new types of attacks. Enhancing security capabilities could be beneficial. Integrating more advanced AI features could significantly improve its effectiveness and help customers leverage these tools more effectively. It would be great to see more focus on AI integration to handle and analyze data more efficiently.
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.
