Room For Improvement

Cloudflare WAF needs feature enhancements, better usability, improved support, advanced DDoS protection, and solutions for latency and alerts.
AWS WAF requires improved integration, usability, security features, and flexible pricing to better support global users and services.
Imperva needs to enhance failover, SIEM integration, GUI, analytics accuracy, real-time visibility, and pricing for better user experience.
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
Compared to firewalls, WAFs generally provide limited stateful analysis capabilities.
Security Engineer at a computer software company with 1,001-5,000 employees
The way we see it now is just mentioned as a percentage from bots and actual users, which should include proper graphs and detailed information.
Infrastructure Lead at Danat Fz LLC
Features like bot protection or DDoS mitigation, available with other WAF vendors, do not come natively with AWS WAF.
Security Analyst at M2P Fintech
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.
AWS WAF offers cost-effective, pay-as-you-go pricing, starting at $5 monthly, valued for integration with AWS services.
Impera's pricing varies widely; high costs are offset by advanced features, but complex licensing may limit website protection.
Due to our status as an AWS shop, AWS WAF is cost-effective for us, and we benefit from discounts due to our extensive use of AWS services.
Security Engineer at a computer software company with 1,001-5,000 employees
The licensing cost for AWS WAF is just pay-as-you-go; it is a service-based model.
Infrastructure Lead at Danat Fz LLC
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.
AWS WAF offers threat blocking, scalability, automation, and seamless integration, enhancing security and performance with easy deployment and affordability.

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
The biggest benefit of AWS WAF for us is to filter malicious requests, so we can protect our environment and application from malicious actors.
Infrastructure Lead at Danat Fz LLC
It has also helped to improve the posture of our application, prevent all DDoS attacks, and unnecessary traffic and SQL injection that is reducing the performance of our application.
DevOps Engineer at a tech vendor with 1,001-5,000 employees
The cloud-native nature of AWS is crucial since most of our workload is in AWS, making AWS WAF native to Amazon Web Services.
Security Analyst at M2P Fintech
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.

For improvement in AWS WAF, we can have better monitoring. One of the things that should be improved in AWS WAF is the monitoring; we need to identify the requests and where they are coming from. If it's a bot, we should differentiate the requests, whether they are automated or not. The way we see it now is just mentioned as a percentage from bots and actual users, which should include proper graphs and detailed information. We also need a feature where we can filter specific requests. If there are scripts in the requests, we should be able to filter those requests to see if there are any scripts running from them.

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.
