Offers a huge signature repository and is superiorly effective in mitigating DDoS attacks
The solution's learning curve can still be further reduced, which presently stands at two or three months. The product has a custom rule set that users can modify and manifest as needed. The vendor can probably shorten the learning curve using cutting-edge technologies like AI. The solution provider can also work around the web applications and identify the toolset that needs to be implemented to deploy the solution in less time. The vendor has launched a SASE product that can function with Cloudflare Web Application Firewall, but many improvements are needed in terms of features, such as the web filtering feature, and CASB has not yet been added.

It gives you one console to see all of your assets, review their configurations, and build your processes
Most customers use Prisma Cloud for visibility and compliance. Prisma has so many features, but many organizations do not use them. They primarily use the visibility part to connect all their cloud accounts and hosts for visibility to see if they are missing any security controls or if they have any misconfigurations. You can connect it to cloud environments such as Azure, AWS, Oracle Cloud, Alibaba, etc., or to an on-prem data center. Prisma Cloud gives you so many options to automate processes related to your daily operations. When it comes to cybersecurity, you can automate things with their existing APIs. They also have out-of-the-box integrations with many solutions. I have not seen any limitations. Everything is customizable. You can do whatever you want, defining the reporting and custom use cases. They recently updated the UI, so it's much better than before.

Geo-localization and IP reputation help to keep our clients secure and more available
The area that should be improved is licensing. When using an active/passive cluster, we have to pay 70% of the master appliance and license for the passive server that does not work. Since we know that only one server works at a time, we should pay only one license for the appliances and for the support as well. In my opinion, this has to be improved. If possible, the client software should be a web application instead of downloading software for the management. This can avoid login problems when they update or patch.

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."
"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."
"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."
"The product has a valuable security control functionality."
"The rate limiting features and customizations in terms of URL match and applying policies are valuable to me."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"The most valuable feature of Prisma Cloud is WAF (web application firewall)."
"With the query language, we can analyze logs and find out which IPs are malicious. It also provides a graphical representation. It provides the overall visibility and how the traffic is flowing. We can see where the malicious IP is and whether it is an insider threat or an outsider threat."
"It has helped us understand the dynamic topology of our containers, and manage security through the application of policies that our pipelines apply straight from Git."
"My favorite feature is the CWPP module. We can define various kinds of rules for vulnerabilities, incidents, or suspicious activities."
"It provides insights into potential vulnerabilities in our code, helping us identify and rectify issues before they can be exploited."
"What I like most about Prisma Cloud is its zero-day signatures, maximum security, minimal downtime, cloud visibility, control, and ease of deployment."
"The most valuable feature is the closed VPN connection, which provides better performance than traditional VPN boxes. For example, let's say a user in New York State normally connects in the East, but if they travel to the UK, they can connect to the same portal, which automatically redirects to any VPN gateway. We can control traffic based on Active Directory groups instead of the user's IP. That means a user in New York can access his application based on his user ID and AD group access when he travels to the UK or anywhere else."
"CSPM is very useful because it gives us good policies and violation alerts."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"The reporting could be more granular."
"Their documentation could be better. They don't have documentation that explains everything well. They have documentation for everything you're looking for, but they lack a single piece of documentation to tie everything together. As a new user or beginner, it took us a little bit of time to figure out how to put all these things in place."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"Cloudflare Web Application Firewall should include port forwarding features."
"Its stability could be better."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"We have noticed some latency when the call goes through the firewall. That could be improved."
"The solution's learning curve can still be further reduced"
"Prisma could improve the data quality. One challenge is that when an application is deployed on multiple virtual machines, we get an alert for each machine, but the biggest challenge is container flapping. When containers go up and down, we get 100 alerts on one day, but it reports 20 the next day. The numbers keep changing, and the app owners tell us, "You reported a hundred vulnerabilities from my app, and today, you report 20. I haven't made any changes in production, so is your data correct or not?""
"The deployment and onboarding are plug-and-play, but somewhat hard to handle in terms of integration with external operations tools. The product design isn't up to the current standard. I would recommend having higher standards in terms of integration with other tools, especially operationalized tools."
"The Fargate security microservice that's running doesn't support blocking features, which would be helpful. Another issue is the lifecycle. It isn't easy to upgrade if we have a console in Fargate."
"They charge seven workloads for monitoring one compute, and that is quite expensive. This makes it difficult to move fully with the compute part because of the workload."
"They could improve more features for the enterprise version of the solution."
"The first time I looked at Prisma Cloud, it took me a while to understand how to implement the integration or how to enable features by using the interface for integration. That portion can probably be improved."
"When it comes to protecting the full cloud-native stack, it has the right breadth. They're covering all the topics I would care about, like container, cloud configuration, and serverless. There's one gap. There could be a better set of features around identity management—native AWS—IAM roles, and service account management. The depth in each of those areas varies a little bit. While they may have the breadth, I think there's still work to do in flushing out each of those feature sets."
"Some of the usability within the Compute functionality needs improvement. I think when Palo Alto added on the Twistlock functionality, they added a Compute tab on the left side of the navigation. Some of the navigation is just a little dense. There is a lot of navigation where there is a tab and dropdowns. So, just improving some of the navigation where there is just a very dense amount of buttons and drop-down menus, that is probably the only thing, which comes from having a lot of features. Because there are a lot of buttons, just navigating around the platform can be a little challenging for new users."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"Cloudflare Web Application Firewall is more affordable than other solutions."
"The annual licensing fee is $10,000 USD."
"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."
"The solution's pricing option needs to be more transparent for enterprise clients."
"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."
"We pay $210 per month for CloudFlare WAF."
"Its price is reasonable as compared to other products. The main challenge is explaining the licensing model to customers. It isn't a problem related to Palo Alto. Commonly, people don't understand cloud licensing or security licensing. When they have fixed virtual machines, they know what they are going to be charged, but when it comes to cloud automation, it is hard for them to get clarity in case of high workloads or when they have enabled auto-scaling, etc. It would be helpful if Palo Alto can educate people on their licensing programs."
"Prisma Cloud is affordable."
"Although the cost can be high, the value is worth the price tag."
"The pricing is competitive. From what I have seen in the past, it is on par with the others."
"We are encountering some resistance in the African market regarding the cost of Prisma Cloud."
"The Prisma Cloud pricing is good."
"The price is high. In the future, when there are more competitors at the same level with different clouds, maybe the position will be different."
"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."
