Review summaries and opinions

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
Users report Imperva's significant ROI, citing cost recovery, DDoS protection, reduced cloud bills, and improved efficiency and compliance.
Sentiment score
7.6
Radware Alteon enhances efficiency and security, offering affordability, reliability, and robust load balancing with reduced downtime and management complexity.
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.
 

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's customer service is praised for expertise but criticized for inconsistency, with recent improvements noted by some users.
Sentiment score
7.4
Radware Alteon support is praised for efficiency but needs improvement in response times and language communication barriers.
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.
We never face support issues, and their team resolves any critical issues quickly once they are involved.
There is a dedicated expert answering even the toughest questions.
The customer service and support are excellent.
 

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 Application Security Platform offers strong scalability and reliability, though costs and on-premises flexibility may present challenges.
Sentiment score
8.0
Radware Alteon is highly scalable, efficiently handling large traffic volumes and adapts to enterprise needs with robust 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.
It handles peak loads and thousands of concurrent connections without exceeding 10% utilization.
We have it deployed across multiple geographic locations, benefiting from load balancing resiliency.
I would rate it a nine out of ten for scalability.
 

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
Users find Imperva Application Security Platform reliable and stable, rating its stability highly despite occasional minor issues.
Sentiment score
8.2
Radware Alteon is praised for stability, reliability, and minimal downtime despite past issues resolved through updates.
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.
We've never faced downtime, even during peak transaction hours.
There is minimal downtime, and the solution is quite stable.
 

Room For Improvement

Cloudflare requires improvements in analytics, CDN speed, API, technical support, DNS management, documentation, pricing clarity, and international and reseller support.
Imperva needs UI improvements, competitive pricing, better integration, real-time analytics, and enhanced support for efficiency and transparency.
Enhancements in automation, scalability, cloud integration, and improved cybersecurity tools are needed to address user dissatisfaction with Radware Alteon.
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.
The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client.
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.
They keep integrating new features that sometimes break our production, but we use clustered systems, so we can test those software releases.
Other OEMs offer free courses and hands-on labs on new technologies and features, which we find useful.
Integration with cloud services could be improved.
 

Setup Cost

Cloudflare offers cost-effective, scalable plans with no setup fees, starting from free for small businesses to enterprise-level solutions.
The Imperva platform's pricing is competitive with advanced features, ranging from $5,000 to $10,000 annually and no setup costs.
Radware Alteon is cost-efficient with flexible licensing, offering great value for performance and support, appealing to budget-conscious 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.
For our solution, it was right in the middle of price performance.
The cost of the Radware solution is reasonable and stable.
The implementation and running costs are quite high.
 

Valuable Features

Cloudflare enhances security, speed, and SEO with easy-to-use features like CDN, SSL, DDoS protection, and centralized management.
Imperva's platform offers robust security features, user-friendly integration, real-time analytics, and scalability for diverse enterprise protection needs.
Radware Alteon excels in load balancing, security, and scalability, offering user-friendly management and reliable performance with excellent support.
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 product allows us to manage multiple networks and VLANs into a single box and add numerous web services and farms efficiently.
I find the best features to be the flexibility and ease of use.
The most valuable features include the availability with an optional high-availability mode ensuring service continuity because of the resiliency.

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.

Automated threat detection and blocking helps us manage our security with limited resources
The best thing about Alteon is its automated threat detection and blocking. The university has resource limitations. I am the only one working for the security section, looking after seven products, including Alteon. The automatic blocking of threats and detections is crucial for us. Because there are a lot of things going on, we sometimes miss or do not see the detections on time. So, the most useful thing for us is to have a WAF that automatically blocks anything unusual or suspicious. It is efficient and low maintenance. Once you set it up, you do not have to go back and look into it. It gives us peace of mind that if something comes up, it will block that.
