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 users experienced increased performance, security, and cost-effectiveness, leading to improved loyalty and revenue despite difficult ROI calculations.
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
7.4
Kemp LoadMaster is a cost-effective solution that enhances efficiency, security, and offers significant returns quickly in various industries.
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.
 

Customer Service

Sentiment score
7.0
Cloudflare's customer service is quick, but technical support feedback is mixed, with improvement needed in responsiveness and detailed assistance.
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
8.8
Kemp LoadMaster support is highly rated for its knowledgeable, efficient team offering quick issue resolution and comprehensive online resources.
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.
We have not received technical support from Kemp LoadMaster without a license.
 

Scalability Issues

Sentiment score
8.1
Users praise Cloudflare for seamless scalability, effective traffic management, easy upgrades, and robust global infrastructure without disruptions.
Sentiment score
7.9
Imperva Application Security Platform offers strong scalability and reliability, though costs and on-premises flexibility may present challenges.
Sentiment score
8.2
Kemp LoadMaster is highly scalable, supporting smooth upgrades and adaptable licensing for both small and large enterprises.
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.
Kemp LoadMaster is a scalable solution.
 

Stability Issues

Sentiment score
7.6
Cloudflare is highly rated for stability and uptime, with few past issues, especially on higher-tier plans.
Sentiment score
7.8
Users find Imperva Application Security Platform reliable and stable, rating its stability highly despite occasional minor issues.
Sentiment score
8.7
Kemp LoadMaster is praised for its stability, reliability, high availability, and effective server load management with minimal downtime.
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.
With the license purchase afterwards, if it expires, it begins dropping the HTTP traffic, also the DNS traffic.
 

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.
Kemp LoadMaster needs UI, security, documentation enhancements, improved monitoring, automation, analytics, and better cloud integration.
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.
After that, they said if it was good, we could purchase the license, and while we found it very good, the license cost was too high.
 

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.
Kemp LoadMaster offers flexible, cost-effective licensing and setup with positive user feedback and a 30-day free trial.
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.
 

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.
Kemp LoadMaster offers ease of use, security features, Azure integration, and cost-effective load balancing for Microsoft applications.
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.
We had some issues in patching management, so we deployed this product for virtual patching, the IPS rule, and it gives us very good results because we have very critical servers.

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.
Mitesh D Patel - PeerSpot reviewer
Effectively defends against threats like cross-site scripting (XSS), SQL injection, and others
It does bring value. For example, consider a BFSI customer. Their application is critical and represents their brand. Without a WAF, an attack could take their application down, harming their reputation. It leads to hampering the customer's workflow. With an Imperva WAF, they protect against attacks like DDoS or SQL injection, ensuring their application remains available and customers are happy. That's the main benefit for both the customer and the organization. The impact depends on the customer's use case. If their business primarily operates online, a CDN is beneficial for traffic optimization. Moreover, the integration options depend on the specific use case of our customers. Generally, integration capabilities are good with SIEM (Security Information and Event Management) parts.
IshtiaqKhalil - PeerSpot reviewer
Displays flexible, user-friendly interface with minor licensing challenges
The product could be improved with a more intuitive interface for complex configurations and more advanced analytics. Additionally, enhanced security features, like a more robust Web Application Firewall, and stronger APIs for better automation would be beneficial. Overall, the main areas for improvement are in strengthening the advanced features to better meet the demands of large-scale enterprise environments. key features for the next release should focus on three areas. First, an enhanced, next-generation security suite with a more powerful Web Application Firewall (WAF) and integrated bot protection. Second, more advanced and customizable analytics dashboards to provide deeper insights into application performance. Finally, greater support for modern, cloud-native environments, including better APIs for automation and seamless hybrid-cloud traffic management
