Qualys VMDR boosts ROI by enhancing security, improving asset management, reducing cyber risks, and saving time and resources.
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.
We saw a return on investment through significant savings in time, money, and resources.
 

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
6.7
Qualys VMDR support is responsive and knowledgeable, but users report slow responses and varying service quality.
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 usually get on calls with tech support, and they are very helpful.
The response time takes a while.
The technical support provided by Qualys is pretty good.
 

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
8.0
Qualys VMDR is praised for scalable, flexible asset management across large networks with efficient deployment and cloud-based architecture.
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.
Scalability depends on the license and the number of assets being monitored.
Qualys VMDR can handle scalability, although increasing the inventory can raise the licensing costs.
 

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
8.0
Qualys VMDR is highly stable and reliable, with minimal issues and predictable maintenance for smooth operations.
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.
 

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.
Qualys VMDR simplifies UI and reporting but needs better asset management, support, and advanced analytics for IoT and SCADA.
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 does not automate patching unless the patch management module is purchased separately.
If AI features were integrated, it could enhance the capabilities significantly.
They can tweak their UI since the new version seems a bit jumbled up.
 

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.
Qualys VMDR pricing is higher than some competitors but offers value with integrated features and discounts for larger contracts.
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.
I would rate the pricing between seven to eight out of ten.
I have a notion that Qualys might be more expensive than Rapid7.
Qualys offers better pricing and is feature-packed compared to other tools.
 

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.
Qualys VMDR enhances security management with vulnerability insights, real-time threat detection, and customizable dashboards for improved remediation efficiency.
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 prioritization of vulnerabilities has improved our remediation efforts by around thirty to thirty-five percent.
It impacts my workflow overall, with the patch management features as it has the missing patches listed in detail, making it easier to get a comprehensive report and providing some dashboards that offer visual representation.
Qualys VMDR offers a one-stop solution for monitoring and reporting.

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.
Ankesh Raj - PeerSpot reviewer
Real-time responses and reporting streamline vulnerability management
Qualys VMDR provides a real-time response and reporting feature, which is excellent. It allows us to see real-time graphs and reports for every asset, server, and more, which is very user-friendly.
