Image scanning has supported consistent security practices during cloud deployment
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

"This solution will ensure that we've got a more secure environment, mitigating any sort of bad actors coming in and either destroying or disrupting the environment."
"Prisma Cloud saves a lot of manual effort that we had to do within our cloud organization."
"Prisma Cloud's comprehensive platform offers a range of features, including runtime security and vulnerability assessments, through its Prisma Cloud Compute component."
"CSPM is the most valuable feature for any organization that runs its workloads in the cloud."
"We are provided with a single tool to protect all of our cloud resources and applications without having to manage and reconcile compliance reports."
"I've been really pleasantly surprised with how Prisma Cloud is, over time, covering more and more of the topics I care about, and listening to customer feedback and growing the product in the right directions."
"The most valuable features are vulnerability monitoring, serverless access, container runtime features, and Defender."
"Before implementing Prisma Cloud, we didn't have any visibility into workspaces like Kubernetes and the underlying network of containers, but now we have a better understanding of the resources interacting with Kubernetes and can identify vulnerabilities across the organization."
"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."
"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."
 

Cons

"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 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."
"There is room for improvement on the logging and monitoring front because it's still not as holistic as I would want it to be."
"While Prisma provides a lot of visibility, it also creates a ton of work. Most customers that implement Prisma Cloud have thousands of alerts that are urgent."
"The feedback that we have given to the Palo Alto Networks team is that the UI can be improved."
"Prisma Cloud's enterprise reporting needs significant improvement."
"Sometimes, when you assign subnets to regions, the IP address will jump from one location to another because it will automatically change substantially. Then, we need to add those IP subnets to our firewall for existing access. The need to update those subnets potentially causes maintenance or access issues. So far, we can only provide bigger customers with six subnets, and a small company may not be able to access those services."
"The tool's UI is an area with certain shortcomings where improvements are required."
"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."
"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 UI is not very intuitive and could be better."
 

Pricing and Cost Advice

"Our licensing fees are $18,000 USD per year."
"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."
"Prisma Cloud is affordable."
"We are encountering some resistance in the African market regarding the cost of Prisma Cloud."
"The pricing is reasonable."
"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."
"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 product has an affordable cost."
"Signal Sciences is pretty cheap compared to other solutions."
"The pricing is 50% less than Akamai."
