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 management has reduced ransomware risk and now protects cloud workloads efficiently

The best features that Barracuda WAF-as-a-Service offers are an intuitive centralized dashboard, allowing us to manage policies, Internet protocol servers, antiviruses, anti-DDoS attacks, and traffic shaping across multiple sites. This feature enables seamless scaling of our environments, especially as we work within Amazon Web Services. Additionally, real-time threat intelligence helps us to detect threats in real-time. Another major feature I love is application control and VPN support, providing granular visibility and protection without needing separate appliances. The centralized dashboard is helping us streamline visibility across our admin panels and provides site-to-site visibility deployed directly to our AWS environment, securing VPC traffic and ensuring the firewall is in place. The real-time threat intelligence is an advanced feature helping us track real-time attacks, such as anti-DDoS attacks, ransomware, or viruses that can compromise system integrity. Through the intuitive centralized dashboard, we can manage policies and set rules, assisting us effectively.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The initial setup process is simple."

"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."

"I have not had any issues with this solution, and I would recommend it to others who are interested in using it."

"It protects web applications efficiently."

"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."

"Cloudflare is cheaper compared to Azure WAF, which I have considered before."

"Some of the most valuable features of Cloudflare Web Application Firewall include its DNS zone setup and the zero trust policy."

"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."

More Cloudflare Web Application Firewall pros

"Barracuda WAF-as-a-Service's real-time attack detection feature has improved our customers' threat response strategies significantly."

"I like its ability to identify known attacks, including DDOS attacks, because application attacks are evolving all the time and, when it comes to software-as-a-service, we need to have software that knows about all the latest attacks and also protects against major unknown attacks."

"The most valuable features of the solution are it is plug and play, has automated policies, a simple configuration, and is easy to create rules."

"The solution covers a lot of major protection or threat management functions in the feature itself."

"The most valuable features of the solution are it is plug and play, has automated policies, a simple configuration, and is easy to create rules."

"I like its ability to identify known attacks, including DDOS attacks. It's valuable because software must be able to stop known attacks. Application attacks are evolving all the time. When it comes to software-as-a-service, we need to have software that knows about all the latest attacks. It should also protect against major unknown attacks."

"The solution can be used for threat prevention or as a cloud-to-cloud backup system"

"It provides an ease of policy management."

More Barracuda WAF-as-a-Service pros

"It has helped us to increase the resiliency of the application and the performance."

"The most valuable features of Citrix ADC are load balancing and application firewall."

"I like the monitoring ability as it enables me to identify when an internal (load-balanced) resource is having issues before it becomes a problem in production."

"Compared to other solutions, Citrix ADC is much more robust in terms of the native integration to cloud platforms, and it is far more robust from an operational point of view as well."

"If you need PCI-compliance and have high security requirements, WAF is the most valuable feature. If you need to monitor your load-balancing services with complex types of monitoring, make sure everything is alright, and load balancing is important, Content Switching and Monitoring features are the keys to your needs. If you want to provide a lot of static images or data, the Caching feature works best for you."

"I can turn on features without actually owning a license. I can test them out, I can use them for a while, and then I can be licensed up. That's awesome. I don't have to have a license immediately before I can start to deploy things rapidly, rapid deployment is a plus."

"When our primary link goes down I can still get to my Cisco devices and the NetScaler devices on-prem because of the SDN solution. If the internet connection at one of the branches goes down, we can still route them, they still get internet based on the SDN solution through one of the other sites. They can carry on working."

"I like the ease of use, it's easy to manage, and I also like its ease of use with virtualization technologies with applications."

More NetScaler pros

Cons

"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."

"Cloudflare should update the version of the ModSecurity core rule set that they run on."

"Support can be challenging at times."

"It would be ideal if the solution offered better log integration and more integration with different platforms."

"They have some limitations with third-party integrations."

"The platform's control features related to real-time authentication and response time need improvement."

"The learning curve was steep initially."

"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."

More Cloudflare Web Application Firewall cons

"The price of their licensing model is a bit steep, and the pricing and SIEM integration sometimes create challenges, and we need to get professional help with those areas."

"The solution can improve by bundling Security Operation Center (SOC) with the WAF-as-a-Service, it would provide a lot more value to customers."

"It's a very specific solution that is only requested for a customer's web code or their global IT policy."

"One significant area for improvement in Barracuda WAF-as-a-Service lies in its market positioning and pricing strategy."

"The solution can improve by bundling Security Operation Center (SOC) with the WAF-as-a-Service, it would provide a lot more value to customers."

"The stability of the product is an area of concern where improvements are required."

"It's a very specific solution that is only requested for a customer's web code or their global IT policy."

"We found it a bit slow when accessing it through the web browser. The URL also exposed the user name and the hashed password. When I log into my Barracuda WAF user portal, I could see the username and the hashed password on the URL itself. So, it is not very secure, and it is important to take that off."

More Barracuda WAF-as-a-Service cons

"Development team's response time could be better."

"We had some bugs in the previous firmware. These were not big issues, but more testing on the firmware would be key to happier customers."

"It is not perfect because at times I was faced with an issue where the application was getting a lot more traffic than is desirable, and I can see Citrix having issues with this."

"The reporting is not so good. They don't have an application to connect the logs."

"The solution has too many bugs in the software and it's always difficult when you need to update."

"Security could be improved because then I can get rid of my Cisco firewalls."

"Overall the price of Citrix ADC could be more competitive."

"The main areas for improvement would be around documentation and support. If a feature can be used in two or three ways, show that feature being used in all of those ways. Documentation seems to only cover the primary use case and leaves you to either run through trial and error or consult the user community. In terms of support, I have never actually had them solve any of my issues. I have always solved them myself and then provided the resolution to support."

Pricing and Cost Advice

"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."

"The solution's pricing option needs to be more transparent for enterprise clients."

"The annual licensing fee is $10,000 USD."

"It starts at $20 and can easily go up to $200 monthly"

"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."

"It is not too pricey."

"Cloudflare Web Application Firewall is more affordable than other solutions."

"The solution is expensive."

More Cloudflare Web Application Firewall pricing and cost advice

"It's very difficult for me to give an estimate of the cost. All I know is that we sell the box itself as a service."

"I rate the product's price a five on a scale of one to ten, where one is low, and ten is high. There are no additional costs to be paid apart from the standard licensing fees attached to the solution."

"The product is expensive but it offers flexible pricing. It could be affordable."

"The licensing costs for this solution vary depending on which model is being used."

"Licensing is adequate. I wanted to have a more prominent license, but until I do they don't give enough support. The additional cost would be too much."
