I was able to save over seven million dollars last year as return on investment in the company.

We have not faced any significant issues during deployments.
Chief Technology Officer at Future Point Technologies
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
 

Room For Improvement

Cloudflare WAF needs feature enhancements, better usability, improved support, advanced DDoS protection, and solutions for latency and alerts.
Fortinet FortiWeb needs improvements in upgrades, support, threat intelligence, user interface, cloud integration, reporting, stability, and load balancing.
Users seek improved interface, integration, real-time monitoring, support, pricing, reporting, and enhanced security features from Imperva's platform.
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
If the GUI includes notifications and improved logging capabilities that allow us to see traffic and store logs for six months, that would be very helpful.
Technical Support Engineer at Intimesolutions
Fine-tuning is a room for improvement in Fortinet FortiWeb.
Joint Director at PAA
After the customer submits a specific question and requests troubleshooting help from Fortinet support, it takes at least three to five days to provide a proper answer.
Security Team Lead at a outsourcing 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
 

Setup Cost

Cloudflare Web Application Firewall offers affordable, flexible pricing with no upfront costs, noted for competitiveness and included support services.
Fortinet FortiWeb provides flexible pricing and licensing, appealing to enterprises for cost-effectiveness despite some users noting variable costs.
Enterprise users find Imperva's pricing high and complex, but value its robust security features despite costs.
For VM machines, the price increases based on CPU configurations of 2, 4, or 8 CPUs.
Presales Engineer at SAUDI PARAMOUNT COMPUTER SYSTEMS
Most security products charge less at the time of purchase because of competition, but when we go to renewals, the prices become very high.
Joint Director at PAA
Fortinet FortiWeb is cost-effective compared to solutions like F5.
Chief Technology Officer at Future Point Technologies
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
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 pricing is not transparent to me; it's what the vendors give, or whatever the channel partner offers that you can negotiate on.
Head of Tech at CRC Credit Bureau Limited
 

Valuable Features

Cloudflare Web Application Firewall provides comprehensive security features, easy setup, scalability, and competitive pricing with praised performance and stability.
Fortinet FortiWeb provides advanced security features and seamless integration, offering cost-effective, robust protection and easy deployment for enterprises.
Imperva Application Security Platform excels with easy setup, strong DDoS protection, dynamic profiling, and advanced threat intelligence.
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.
Owner at Hga consulting
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.
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.

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.

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.
