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.

On a scale of ten, we would say people are happy with Prisma Cloud by Palo Alto Networks for the part we use. People are okay with it. We probably would give an eight. We don't give ten because if we don't use the other parts of Prisma Cloud by Palo Alto Networks, it's because it was difficult to implement from an operational point of view. We could have deployed the runtime monitoring with Prisma Cloud by Palo Alto Networks, but within our organization at our company, it was very difficult to find who would be the owner for the alerts. People have other tools and in the end, we don't use the full capabilities of a product that we pay for. It's partially related to the difficulty to integrate Prisma Cloud by Palo Alto Networks runtime in our company's support process. We don't use the real-time monitoring part of Prisma Cloud by Palo Alto Networks. We don't know about the automated remediation feature of Prisma Cloud by Palo Alto Networks.

Room for improvement with user interface while competitive pricing impresses
It is managed through Infrastructure as Code, so all configurations can be managed in the code itself, which is beneficial. Because it uses rules, it is easy to set up, and we have many different sites where the configurations are straightforward. Though the UI is not very interactive, which is a downside, we can manage many things. The UI is not very intuitive and could be better. However, we manage all the configurations through code, which is easy to maintain. It has extensive anomaly detection capabilities, so the traffic is classified into several categories where thresholds can be defined and customized based on false positives and false negatives. This is advantageous because you do not need to tweak it very often. Once you set it up, an audit once a quarter would suffice. Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate.

Quotes from Members

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

Pros

"The rate limiting features and customizations in terms of URL match and applying policies are valuable to me."
"Technical support has a very fast response time and they are helpful."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"It is a SaaS solution unlike much of the competition."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"Very glad the WAF rulesets works out of box, and requires very little tuning or maintenance."
"Prisma Cloud by Palo Alto Networks offers very good deep security assessment, and it uses a very good internal engine, which is the core Palo Alto processing and engines."
"Prisma's identity-based micro-segmentation is better than all its competitors."
"The UI is very good. We get all the things within a single UI."
"Technical support is quite helpful."
"The solution gives us a lot of visibility across all of our cloud solutions."
"The CSPM and CWPP functionalities are pretty good."
"In the GlobalProtect module, we can easily guide users experiencing connection issues through the notification column."
"Visibility and control are the most utilized features. A dashboard is available to us where we can view different categories. We can see any IAM-related risks, any discovered vulnerabilities, any incidents, or any network-level issues."
"The product's most valuable feature is its ability to set up the rules easily."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."
"Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate."
 

Cons

"The blocked logs are difficult to read at times."
"The reporting could be improved if it were more granular."
"The solution's learning curve can still be further reduced"
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"Its stability could be better."
"We don't even use Cloudflare Bot Management because it's too expensive; you need to pay per request, and it's much cheaper to get one or two additional machines."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"The visibility on the SIEM needs to be streamlined so we can get the data without any issues."
"The dashboard can be created at the user level instead of the cloud account level, which will help save time."
"This solution is more AWS and Azure-centric. It needs to be more specific on the GCP side, which they are working on."
"Today, I won't recommend Palo Alto Prisma to someone because I'm not confident about their support."
"The pricing for the solution needs improvement."
"I have some challenges customizing and personalizing some of the capabilities in the CSPM in terms of new policies and services. We have to reconfigure and rebuild the CSPM."
"I believe there are some issues with the product's maturity. In some cases, it could malfunction concerning Cloud Native."
"There are hundreds of built-in policies for AWS and Azure, but GCP and Oracle are not covered as much as AWS. There is a lot of work to do on that part. There is, obviously, a tiny bit of favoritism towards AWS because it has the most market share."
"The UI is not very intuitive and could be better."
"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
 

Pricing and Cost Advice

"We pay $210 per month for CloudFlare WAF."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The solution's pricing option needs to be more transparent for enterprise clients."
"The annual licensing fee is $10,000 USD."
"It is not too pricey."
"It starts at $20 and can easily go up to $200 monthly"
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"If you pay for three years of Palo Alto, it's better. If you're planning on doing this, it's obviously not going to be for one year, so it's better if you go with a three-year license... The only challenge we have is with the public cloud vendor pricing. The biggest lesson I have learned is around the issues related to pricing for public cloud. So when you are doing your segmentation and design, it is extremely important that you work with someone who knows and understands what kinds of needs you will have in the future and how what you are doing will affect you in terms of costs."
"Prisma Cloud is affordable."
"The pricing and the licensing are both very fair... The biggest advice I would give in terms of costs would be to try to understand what the growth is going to look like. That's really been our biggest struggle, that we don't have an idea of what our future growth is going to be on the platform. We go from X number of licenses to Y number of licenses without a plan on how we're going to get from A to B, and a lot of that comes as a bit of a surprise. It can make budgeting a real challenge for it."
"Prisma Cloud Enterprise is a costly solution. You need a license for all the components. At the same time, you have everything under one roof, so I think it's still justified."
"One thing we're very pleased about is how the licensing model for Prisma is based on work resources. You buy a certain amount of work resources and then, as they enable new capabilities within Prisma, it just takes those work resource units and applies them to new features. This enables us to test and use the new features without having to go back and ask for and procure a whole new product, which could require going through weeks, and maybe months, of a procurement process."
"Prisma Cloud is more expensive than Check Point CloudGuard."
"Although the cost can be high, the value is worth the price tag."
"Its licensing cost depends on the type of license such as the business license or the enterprise license. The enterprise license is costlier than the business license, but we get more visibility and more modules. If you have a multi-cloud environment and subscribe to each cloud's native CSPM tool, it is costly. If you are using a single tool like Prisma Cloud, with a single license, you can monitor all environments, such as Google Cloud, Azure, AWS, and Oracle Cloud. The cost of Prisma Cloud is less than the cost of subscribing to the CSPM tool of each cloud provider. This is where Prisma Cloud can save costs."
"The pricing is 50% less than Akamai."
"The product has an affordable cost."
"Signal Sciences is pretty cheap compared to other solutions."
