Owner at Hga consulting
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.

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 not even needed support after deployment, since it has remained stable.

IT Manager at Amla Commerce
It is also a stable product without much glitch or downtime.
Senior Presales Consultant at Techlab security
One notable drawback is that, unlike Fortinet, which offers fast track labs and continuous enablement, Imperva Application Security Platform lacks lab access and fast track labs for enablement and product advertising.
CTO at Malam Engineering PLC
The stability of Imperva DDoS is very good, as it seems they have a lot of servers around the world.
Head of Sales Services Department at a comms service provider with 51-200 employees
With the license purchase afterwards, if it expires, it begins dropping the HTTP traffic, also the DNS traffic.
Information Security Engineer at BOK
 

Room For Improvement

Cloudflare WAF needs feature enhancements, better usability, improved support, advanced DDoS protection, and solutions for latency and alerts.
Users recommend improving Imperva's visibility, integration, AI, analytics, licensing, POPs, dashboard, support, documentation, and threat detection.
Kemp LoadMaster needs UI, security, documentation enhancements, improved monitoring, automation, analytics, and better cloud integration.
The product can improve by having more multitenancy capability, which is currently not available.
Network Architect at a computer software company with 11-50 employees
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.
Owner at Hga consulting
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.
CTO at PlayNirvana
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
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.
Information Security Engineer at BOK

Imperva's pricing offers varied experiences, from affordable to expensive, influenced by user needs and varying licensing models.

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

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.
Owner at Hga consulting
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
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.
Information Security Engineer at BOK

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.

Strong policies and bot defenses have secured critical APIs and have reduced attack noise
From my research regarding the IAM space that Imperva Application Security Platform is trying to look into, I believe they still need to do a lot of modeling and modification to make sure that also helps. There are several competitors in the IAM space, so Imperva would do well if they can do some basic modeling and modifications from my own personal research and my own experience in the IAM space. Alternatively, they could actually just focus on trying to be stronger in the web application space and the database activity monitoring space.The main reason it is not a perfect ten is regarding support. At times, having to reach the support team takes eight hours to ten hours maximum. There are times when clients could have urgent issues to attend to. The support team could do more by having a faster response rate.

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
