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

"There is a huge signature repository"
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"The product has improved our security posture by blocking bad actors."
"The product has a valuable security control functionality."
"It protects web applications efficiently."
"It is configurable via API."
"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"Prisma Cloud saves a lot of manual effort that we had to do within our cloud organization."
"The visibility on alerts helps you investigate more easily and see details faster."
"Prisma Cloud's monitoring features such as the compute compliance dashboard and the vulnerability dashboard, where we can get a clear visualization of their docker, have also been valuable. We can get layer-by-layer information that helps us see exactly where it's noncompliant. They update the dashboards quite frequently."
"Visibility is a key feature. Integration with other technologies across the board, whether they are Palo Alto technologies, Windows technologies, or cloud technologies, is probably the biggest thing."
"Integrating with a CI/CD pipeline and incorporating a vulnerability assessment process are highly effective features, especially when combined with runtime protection."
"It's definitely a good product, and if a company is heavily into the public cloud environment, they must look to use a product like this to gain good visibility into their security."
"It is a good solution. Each team should utilize it. Every good organization is now moving towards or trying to be provider agnostic, so if you are using multiple providers, you should at least give Prisma Cloud a try."
"Prisma scans things and shows all the vulnerabilities and packages that are vulnerable, and which layers, by default, have vulnerabilities. So developers can easily go into the package or a particular layer and make changes to their code. It's very transparent."
"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."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"The product's most valuable feature is its ability to set up the rules easily."
 

Cons

"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"The dashboard could be more user-friendly."
"The solution's learning curve can still be further reduced"
"Support can be challenging at times."
"The product can improve by having more multitenancy capability, which is currently not available."
"The reporting could be improved if it were more granular."
"They could improve more features for the enterprise version of the solution."
"Runecast gave us more visibility into VMware's private cloud. We have more environments there, but Prisma's lack of visibility into the private cloud was a downside—there weren't many."
"The UX part of Prisma's user interface could be simplified and the metrics tool should be highlighted more."
"A better correlation between the multiple products Prisma Cloud contains would be crucial. It would reduce the time spent looking at reports and enable you to get all the actionable insights across products. I think that Palo Alto is working on it, but they need to work faster because it doesn't make sense to have all these products in a single pane of glass without any correlation between them."
"We would like it to have more features from the risk and compliance perspectives."
"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."
"While the code security feature has undergone recent enhancements, there is room for improvement in terms of its cost module."
"The pricing for the solution needs improvement."
"The UI is not very intuitive and could be better."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"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."
 

Pricing and Cost Advice

"Cloudflare Web Application Firewall is more affordable than other solutions."
"It starts at $20 and can easily go up to $200 monthly"
"It is not too pricey."
"We pay $210 per month for CloudFlare WAF."
"The solution is expensive."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"What's my experience with pricing, setup cost, and licensing? I believe the pricing is not the best, but it's reasonable and acceptable. We also use the McAfee system in parallel. In terms of pricing, its okay - not great, but not bad either. It falls in the middle, which is acceptable. In terms of support licensing, last time, we were searching for a solution, and we considered products from resellers rather than directly from the cloud provider. However, the pricing we encountered was exceptionally high. As a result, we are inclined to select support from the reseller."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"This solution is good for a company with at least 400 people that must be connected remotely. For smaller companies, it can be too expensive."
"Our licensing fees are $18,000 USD per year."
"The cost depends on the pricing model. Compared to other solutions, the cost isn't that bad."
"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."
"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."
"I find the pricing to be expensive."
"The Prisma Cloud pricing is good."
"The pricing is competitive. From what I have seen in the past, it is on par with the others."
"The pricing is 50% less than Akamai."
"Signal Sciences is pretty cheap compared to other solutions."
"The product has an affordable cost."
