Security Specialist at a tech services company with 1,001-5,000 employees
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.
Owner at Hga consulting
The return on investment for me is significant as time is the critical aspect.
Senior Network and Security Expert at a financial services firm with 201-500 employees
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.
Head of Sales Services Department at a comms service provider with 51-200 employees
I was able to save over seven million dollars last year as return on investment in the company.
Senior Cybersecurity Consultant at Cyberoutcome Limited
I have seen a return on investment with Imperva Application Security Platform, as it is generally associated with time savings, because the review of alerts and the visibility it gives saves us significant operational time.

It is a SaaS tool, but the fact that they have workloads deployed across the world proves that it is a highly scalable tool.
Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees
The tool offers very good performance, even during high-traffic periods.
Engineer at SITMEXICO
Cloudflare's scalability is quite good; it is very easy to scale whenever we want to include multiple domains.
Senior Network and Security Expert at a financial services firm with 201-500 employees
99% of customers are using the cloud version of Imperva DDoS protection, so they just purchase the new license and scale as needed.
Head of Sales Services Department at a comms service provider with 51-200 employees
I have not even needed support after deployment, since it has remained stable.
CTO at Malam Engineering PLC
It is easy to always scale to add more users.

Room For Improvement

Users suggest improvements in Cloudflare's features, pricing, support, analytics, documentation, and partner relations for better service experience.
Imperva Application Security Platform needs better integration, simpler dashboards, improved AI, and enhanced user interface for higher satisfaction.
Qualys VMDR needs improved support, efficient reporting, UI, asset notifications, reduced tool dependency, better pricing, and comprehensive resources.
Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements.
General Manager at bKash Limited
What Cloudflare is doing internally is that it is stepping ahead in areas like detection and protection.
Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees
Cloudflare could be improved by introducing a mid-tier pricing option.
Security Specialist at a tech services company with 1,001-5,000 employees
To convince my clients, a purely on-prem solution would be ideal since they are financial institutions.
CTO at Malam Engineering PLC
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.
Head of Sales Services Department at a comms service provider with 51-200 employees
Regarding return on investment, ROI, I can say it is noticeable with Imperva Application Security Platform.
Senior Presales Consultant at Techlab security
It does not automate patching unless the patch management module is purchased separately.
System Admin at a tech services company with 10,001+ employees
If AI features were integrated, it could enhance the capabilities significantly.
Information Security Analyst at a tech services company with 51-200 employees
One area where Qualys VMDR can be improved is the missing feature for deploying agents for over 1,000 assets, as we need to do it manually.
Cyber Security Solution Engineer at a computer software company with 201-500 employees
 

Setup Cost

Cloudflare provides cost-effective, feature-rich plans for varying traffic needs, offering significant value compared to competitors like Akamai.
Imperva's Application Security Platform has high, complex pricing, yet some find it competitive for its security benefits and enterprise flexibility.
Qualys VMDR pricing is high for small businesses but offers flexibility, discounts, and comprehensive features for larger enterprises.
I find it to be cheap.
Engineer at SITMEXICO
The tool is a premium product, so it is very expensive.
Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees
However, the enterprise price for small projects is a bit high.
Security Specialist at a tech services company with 1,001-5,000 employees
I would rate the pricing of Imperva DDoS as five, where one is very cheap and ten is very expensive.
Head of Sales Services Department at a comms service provider with 51-200 employees
the setup cost was high, with the hardware installation in the data center being particularly expensive.
Cyber Security Product Owner at a energy/utilities company with 10,001+ employees
We have noticed faster response times and fewer security alerts because after doing some custom policy tuning, everything seemed to be aligned and we have fewer attacks to monitor and fewer alerts to monitor.
Senior Cybersecurity Consultant at Cyberoutcome Limited
I would rate the pricing between seven to eight out of ten.
System Admin at a tech services company with 10,001+ employees
I have a notion that Qualys might be more expensive than Rapid7.

Valuable Features

Cloudflare offers superior caching, DNS management, and security, enhancing performance, global reach, and domain management with innovative features.
Imperva Application Security Platform offers robust threat protection, user-friendly interface, and comprehensive reporting for enhanced web security management.
Qualys VMDR offers user-friendly management, real-time insights, and powerful integrations, significantly improving vulnerability prioritization and remediation efficiency.
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.
Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees
Most of our DNS records that are presented to the internet are proxied whenever possible, providing another layer of defense from our perspective.
Senior Security Engineer at ManpowerGroup
Cloudflare has positively impacted our organization by giving us flexibility to manage the DNS part, being quite fast, and allowing us to manage everything from a single dashboard.
Senior Network and Security Expert at a financial services firm with 201-500 employees
The API security feature is particularly valuable because most attackers do not try to come in from where it is expected.
Senior Cybersecurity Consultant at Cyberoutcome Limited
If someone attempts to access the server, the WAF blocks that SSRF alert, or RCE, Remote Code Execution alert, blocking immediately based on the signature, not only by the payload or the IP address.
SOC Analyst L1 at CMS-IT-SERVICES-PVT-LTD
It reduces the DDoS attacks and reduces the attacks from threat actors, including SQL Injection and zero-day attacks, by using dynamic application profiling from Imperva.
IT Security Analyst & Engineer (Project, Remote) Australia-Europe at a manufacturing company with 10,001+ employees
The prioritization of vulnerabilities has improved our remediation efforts by around thirty to thirty-five percent.
Works at a comms service provider with 1-10 employees
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.
JMS, RPSG Ventures Limited at RP Sanjiv Goenka Group
Qualys VMDR's continuous monitoring capabilities help us respond to emergent threats by enabling my team to reach out to the security engineers whenever there is any detection of a vulnerability, informing them about it, and creating an incident.

Advanced protection has secured critical web workloads and provides clear traffic visibility
From a security perspective, there remains a security loophole, as some browsers in the market can bypass the Turnstile solution, which requires approximately 40 seconds to do so. From a performance perspective, this is acceptable. We also tried Google reCAPTCHA, and that can also be bypassed. From a security perspective, I would say neither solution is completely secured. Regarding uptime, we have faced a couple of incidents due to Cloudflare in recent years, so I cannot say we receive 100% uptime for our region. We sometimes face challenges, including downtime and other issues. As a result, we are not receiving 100% uptime from Cloudflare's solution. Since most of our customers are in this region, we need alternatives. We need something more competitive than Cloudflare. Unfortunately, in Bangladesh, Cloudflare has three points of presence already, and we cannot find any other solution provider in Bangladesh as an alternative, which presents another challenge. Competitor solutions have more attack signatures, which ensure better security compared to Cloudflare's predefined configurations. Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements. Cloudflare could improve in this area. Additionally, regarding visibility, Cloudflare has static visibility, but they could adopt dynamic graph features for their customers.

Senior Associate at a tech vendor with 10,001+ employees
Application protection has improved and reporting and dashboards still need refinement
I believe Imperva Application Security Platform should have a more interactive wizard. While the dashboard is good, it could be more eye-catching. Based on my perspective, I recommend modifying the dashboards, especially the main dashboard where I can see the traffic hit count, alerts, and other latest information. In terms of reporting, I find it challenging to create reports; in my earlier days, it was difficult. Over time, I have learned how to create reports, but it should be easier to do so. I have used other tools such as firewalls or SolarWinds, where creating a report is straightforward and does not take much time, unlike in Imperva, where I have to add many elements. Modifications in the integration aspects would also be beneficial.

Continuous risk-based monitoring has strengthened incident response and vulnerability prioritization
I haven't explored Qualys VMDR's vulnerability lifecycle automation yet. One of my analysts mentioned that queries lack grouping operators in Qualys VMDR. From my experience, I would appreciate improvements in the query options in Qualys VMDR, specifically in the query-building process where I would need more features and operators. Additionally, we have been facing issues with Qualys on the cloud level. We cannot download the configuration profile from the cloud agent, and it is showing a pending action for download. During 2025, we noticed outages of Qualys a couple of times. I want to mention that there is an issue with receiving timely RCA deliveries. While this is not necessarily about the tool, it relates to support. The support has not been very responsive, and we are receiving RCAs a little delayed whenever we raise support cases or communicate with the TAMs. Additionally, the UI has a slight latency, which I and my team have experienced. They have also reported this latency issue when navigating through different pages.
