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.

Detailed container image reports have improved vulnerability insight and support secure operations
Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning. Tenable.io Container Security is giving me the vulnerability information of Docker images and the information about software bill of materials. However, my challenge at this time is that I am using all these solutions with GitLab Ultimate, and it does not support integration, so I am doing some alternate arrangements which are giving me operational complexity because I need to introduce something else instead of GitLab Ultimate. That is the primary concern regarding the benefits of real-time visibility into my containerized application security status.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It supports the multi-cloud environment beautifully."
"CSPM is very useful because it gives us good policies and violation alerts."
"Prisma Cloud is quite simple to use. The web GUI is powerful. Prisma Cloud scans the overall architecture of the AWS network to identify open ports and other vulnerabilities, then highlights them."
"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."
"The solution will streamline and minimize manual efforts."
"We have standardized vendor process management, so we want to reduce multiple vendors. Prisma Cloud is part of Palo Alto. We use Palo Alto firewalls and other solutions. Prisma has many features that intelligently cover cloud security. One solution can cover runtime for EC2 systems, containers, and Fargate. We also have EKS/Kubernetes integration. So, whatever the cloud-native solution in Pfizer, we can use one solution to secure that."
"One of the things that we have been able to do with Prisma Cloud is that we have been able to generate real-time alerts and share them with our technology team, and the turnaround time between us identifying a security gap and then closing it has gone down drastically, as we have reduced the timeline by 30%."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"The strong security provided by the product in the container environment is its most valuable feature."
"Nessus scanner is very effective for internal penetration testing."
"Tenable.io detects misconfiguration when you deploy a Docker or Kubernetes container. It's much better to remedy these issues during deployment instead of waiting until the container is already in the production environment."
"It is a scalable solution. Scalability-wise, it is a good solution."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"By using Nessus, we are able to finish testing with assured results, in half the time."
 

Cons

"Prisma's notifications aren't up to industry standards."
"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."
"Prisma is the result of multiple Palo Alto acquisitions, like CWPP, Twistlock, and Aporeto. Though they are part of a single pane of glass, there is no correlation between the solutions."
"The initial setup was very complex."
"I would like Prisma Cloud to improve its mapping feature to increase usability."
"Based on my experience, the customization—especially the interface and some of the product identification components—is not as customizable as it could be."
"They could improve more features for the enterprise version of the solution."
"They are missing some compatibility details in their documentation."
"The solution’s pricing could be improved."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"They need to work on auto-remediation so it's easier for the security team to act quickly when certain assets or resources are deployed. The latest version has a CIS benchmark that you need to meet for containers in the cloud, but more automation is needed."
"The initial setup is highly complex."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"The initial setup is highly complex."
"I feel that in certain areas this product has false positives which the company should work on."
 

Pricing and Cost Advice

"Almost all the CSPM tools are pretty expensive."
"The pricing is reasonable."
"The pricing of the solution is fair."
"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."
"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 price is high. In the future, when there are more competitors at the same level with different clouds, maybe the position will be different."
"If a competitor came along and said, "We'll give you half the price," that doesn't necessarily mean that's the right answer, at all. We wouldn't necessarily entertain it that way. Does it do what we need it to do? Does it work with the things that we want it to work with? That is the important part for us. Pricing wasn't the big consideration it might be in some organizations. We spend millions on public cloud. In that context, it would not make sense to worry about the small price differences that you get between the products."
"I wouldn't mind if it were cheaper. We are spending a fair amount of money on Prisma Cloud."
"It's best to be an institutional buyer and directly contact the sales team as they can provide over-the-top discounts for bulk orders."
"I rate the tool's pricing a three out of ten."
"I rate the product’s pricing a six out of ten."
"The solution's pricing is neither cheap nor very expensive."
"The product does not operate on a pay-per-license model."
