Fortinet FortiWeb needs improvements in upgrades, support, threat intelligence, user interface, cloud integration, reporting, stability, and load balancing.
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.
The product can improve by having more multitenancy capability, which is currently not available.

I think they're doing a good job with DNS and as support for any domains that I create or that my clients create, it's mandatory for me to ensure they have Cloudflare as their DNS provider.

the setup cost was high, with the hardware installation in the data center being particularly expensive.

Valuable Features

The custom rules and the geo-redundant geographical rule feature, which allows me to implement geographical rules for customers, add significant value.
Network Architect at a computer software company with 11-50 employees
The best features of Cloudflare Web Application Firewall are multiple, including the WAF, rate limiter, and bot attack protection.
IT Manager at Amla Commerce
Cloudflare Web Application Firewall's advanced reporting and analytics tools add a layer that we're able to visualize and see before it actually hits the local firewall.

Fortinet FortiWeb has positively impacted my organization because most of our servers and applications are secure from hackers and other security threats.
Joint Director at PAA
Fortinet's pricing is way more competitive than Cisco or Palo Alto.
Global Channel Alliances Lead at a tech vendor with 10,001+ employees
The machine learning-based threat detection is significant, as it uses a learning method that eases the configuration burden, making it very useful.
Chief Technology Officer at Future Point Technologies
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.

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.

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.

CTO at PlayNirvana
Advanced security reporting has protected high-traffic betting platforms from constant attacks
I don't see room for improvement to Cloudflare Web Application Firewall. One thing I don't know much about because we have a dedicated IT team for that, and I'm not involved with Cloudflare much anymore. But if I were to compare them to F5, I would like to see more features that F5 offers. F5 has an option to bring the whole infrastructure, the whole WAF and all their packages, Bot Management, and everything else on your infrastructure. You need to install certain services from their side, and then you can choose if you would like requests to hit your servers immediately or if requests need to be proxied through F5 backbone. That would be a nice addition because we have 90% of the traffic as legit traffic coming from whitelisted servers. If it comes from whitelisted servers, I don't need to go every request through the backbone; I could easily just IP whitelist everything. Then I could maybe have Bot Management on my infrastructure that drastically reduces the price of Cloudflare. I would like to see Push CDN more improved in the next release of Cloudflare Web Application Firewall. And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network. From our perspective, if we have a listener that listens for stock updates, I would just need to have one processor that pushes those updates to the Cloudflare API, and then Cloudflare would broadcast that message to all listeners. Cloudflare will check the order of the message, and if you, as a customer, are not connected or have some kind of network issue, when you reconnect, you will receive the latest state and missing updates.

Security threats have been reduced through seamless deployment and strong integration with other tools
I have used Fortinet FortiWeb's integration features. We have easily integrated all of the applications with the product. Most of the applications we are using are in-house built. My technical team is looking after the best features. I have not used it extensively for maybe two and a half years. I have been involved in the installation, but I am not actually using the product. I work with it from time to time but not extensively. I would assess Fortinet FortiWeb's adaptive machine learning and artificial intelligence as having new patches installed regarding artificial intelligence, but when we bought it, I think the learning feature was there. Now they have installed artificial intelligence features through patches. We have a complete portfolio of Fortinet in our organization, including FortiMail, Fortinet FortiWeb, and FortiGate, along with multi-factor authentication. All of the products are from Fortinet. Fortinet tools integrate with each other and work in conjunction. I think Fortinet FortiWeb has helped us meet regulatory compliance because we are not a regulatory organization, but our sister organization is regulatory. We have regulatory compliance with the International Civil Aviation Authority, whose audit teams have checked our data center and these security products, and they are satisfied with us. The question about leveraging Fortinet FortiWeb's automated policy management does not pertain to my domain because I am not so technical, but I am in a management role now. My engineer is more technical than me. I would rate this product an eight point five out of ten.

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.
Vaibhav Ghule - PeerSpot reviewer
Soc Lead & Edr Administration at Persistent Systems
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.
