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

"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."
"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"The initial setup process is simple."
"Technical support has a very fast response time and they are helpful."
"There is a huge signature repository"
"This solution does a good job of preventing web application attacks, SQL injections, and cross-site scripting attacks."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"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 most valuable feature is that the rule set is managed and that it can be run on a regularly scheduled basis."
"Prisma Cloud's most valuable feature is its user identification capabilities."
"The most valuable features are vulnerability monitoring, serverless access, container runtime features, and Defender."
"Syslog CLIs are the best feature."
"Through Prisma Cloud, we can write Lambda functions, configure policies to check the security posture, and get reports. We can do a lot more."
"The two most valuable features are container security and the capability to discover workloads."
"Prisma Cloud's most valuable asset is its ability to provide detailed visibility into container activity."
"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."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"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

"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."
"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."
"Its stability could be better."
"The blocked logs are difficult to read at times."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"It would be ideal if the solution offered better log integration and more integration with different platforms."
"The ModSecurity core rules need to be updated."
"WAF doesn't directly affect bandwidth costs. It saves costs on protection. However, with the correct setup, it's difficult to determine if it saves costs overall due to the fixed enterprise plan fee."
"We identified two things that we felt would be great to have, but they are under NDA. So, I can't disclose them. Other than those two things, we identified a generic bug in the secret key management service on AWS that needs to be fixed. We reported it to them, and we want them to fix it."
"There I saw one feature called dummy payloads, in which we trigger the dummy payload, so it exactly gives the exploitable resources. That might be a feature that would be helpful if Prisma Cloud by Palo Alto Networks also had some kind of that feature."
"It would be ideal if they could somehow reduce the deployment time."
"When there are updates, whether daily, weekly, or monthly, it needs configuration or permission adjustments. There is no automation for that, which is too bad."
"The training documentation provided for the two-hour boot camps is notoriously poor and disorganized."
"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."
"More documentation with real-world use cases would be helpful."
"There should be some kind of automation, AI incorporation, and bot system. All these would add value."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
"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."
"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

"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."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The solution is expensive."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"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."
"The solution's pricing option needs to be more transparent for enterprise clients."
"The product is very expensive, but the cost is a necessary evil; I don't know how we could have any kind of cloud presence without this type of monitoring. The pricing is calculated by module and resource usage. Ultimately, it saves us money in the amount of time we would spend uncovering what it uncovers, and we might not make the required discoveries without it anyway. Prisma offers incredible value, though I wish it were cheaper."
"The licensing cost is a bit high on the compute side."
"The pricing is competitive; for the most part, the security firms have similar prices."
"The Prisma Cloud pricing is good."
"I don't know a better way to do it, but their licensing is a little confusing. That's due to the breadth of different types of technologies they are trying to cover. The way you license depends on where you're securing. When they were Twistlock it was a simple licensing scheme and you could tell what you were doing. Now that they've changed that scheme with Palo Alto, it is quite confusing. It's very difficult to predict what your costs are going to be as you try to expand coverage."
"The pricing is competitive. From what I have seen in the past, it is on par with the others."
"Prisma Cloud is cost-efficient, but the credits are on the higher end."
"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."
"The pricing is 50% less than Akamai."
"Signal Sciences is pretty cheap compared to other solutions."
"The product has an affordable cost."
