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 stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"The rate limiting features and customizations in terms of URL match and applying policies are valuable to me."
"The product has improved our security posture by blocking bad actors."
"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."
"The security features are valuable. The particular feature we use is called OWASP."
"The setup process is very simple for me."
"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."
"Engineering is thinking it's easy to integrate because we use many Red Hat products."
"Syslog CLIs are the best feature."
"The most valuable features are the alerts and auto-remediation because it allows us a lot of flexibility to customize and do things the Palo Alto team never intended. We faced some challenges with certificates because we also have next-gen firewalls. We would like to equip all the traffic because there have been many cases in which the developers have done things by mistake. Deploying certificates on virtual machines can be complex in a development environment, but we managed to do that with Prisma Cloud."
"The support is excellent."
"Integrating with a CI/CD pipeline and incorporating a vulnerability assessment process are highly effective features, especially when combined with runtime protection."
"Aporeto has accelerated our client's expansion to the cloud, securing their Linux workloads on any infrastructure with end-to-end encryption and providing a path for modernizing with a security layer that is future-proofed."
"We found it to be easy and flexible. We could easily configure it for our needs, and we could spread the Prisma Cloud platform to 16 countries without encountering any kind of problem."
"It supports the multi-cloud environment beautifully."
"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."
"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."
 

Cons

"It would be ideal if the solution offered better log integration and more integration with different platforms."
"A key challenge arises when dealing with numerous integrations with HVAC systems. Depending on the specifics, there might be some configuration mismatches, which necessitate specific support."
"Cloudflare Web Application Firewall should include port forwarding features."
"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."
"Support can be challenging at times."
"Its stability could be better."
"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."
"The product can improve by having more multitenancy capability, which is currently not available."
"The automation must continue to become much smoother."
"The feedback that we have given to the Palo Alto team is that the UI can be improved. When you press the "back" button on your browser from the Investigate tab, the query that you're working on just disappears. It won't keep the query on the "back" button."
"This solution is more AWS and Azure-centric. It needs to be more specific on the GCP side, which they are working on."
"We'd like to have more native integration with clouds and additional security checks in the future."
"Areas like the deployment of their defenders and their central control need manual intervention. They should focus more on automation. They have a very generic case for small companies. However, for bigger companies to work, we have to do a lot of changes to our system to accommodate it. Therefore, they should change their system or deployment models so it can be easy to integrate into existing architectures."
"The data security model needs improvement due to integration issues with certain features and cloud providers. With Palo Alto now utilizing a tool from an Israeli startup in Prisma Cloud, the integration is slow, and some features are blocked or not supported."
"In terms of securing cloud-native development at build time, a lot of improvement is needed."
"I think Prisma Cloud could improve its preventive governance policy and CWP run time modules."
"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

"It is not too pricey."
"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."
"We pay $210 per month for CloudFlare WAF."
"It starts at $20 and can easily go up to $200 monthly"
"The solution is expensive."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The annual licensing fee is $10,000 USD."
"From my exposure so far, they have been really flexible on whatever your current state is, with a view to what the future state might be. There's no hard sell. They "get" the journey that you're on, and they're trying to help you embrace cloud security, governance, and compliance as you go."
"Prisma Cloud is a value-back cloud-managed solution; cloud-native solutions are quite expensive."
"The pricing for Prisma Cloud is high. Providing a pay-as-you-go model or pricing options tailored for medium and small enterprises could help attract more clients."
"Prisma Cloud's licensing system functions as expected with a solid licensing infrastructure."
"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."
"I wouldn't mind if it were cheaper. We are spending a fair amount of money on Prisma Cloud."
"The pricing is reasonable."
"Regarding Prisma Cloud's pricing, we started small, and then we just kept on growing."
"The product has an affordable cost."
"Signal Sciences is pretty cheap compared to other solutions."
"The pricing is 50% less than Akamai."
