An operational system, similar to Linux where you can run your applications inside containers
With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers. When you mentioned using Nacula as part of your CI/CD pipeline, it means your application is deployed and managed automatically through the CI/CD process. Containers are used to deploy your application within this pipeline, but CoreOS does not run inside these containers. Instead, CoreOS is the base operating system that supports and manages these containers.

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.

Pros

"With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers."
"CoreOS Clair's best feature is detection accuracy."
"I like Prisma's ability to integrate with other tools. We can integrate it with Jira so that when Prisma triggers an alert, it opens a ticket in Jira. That was a big selling point for the product. There's a feature called the guest custom template that allows you to trigger alerts in Jira based on the template. That can also be added as a feature on Jira."
"The most valuable feature is that the rule set is managed and that it can be run on a regularly scheduled basis."
"The opportunity in our company is good because we are already using Red Hat at different stages of cloud computing."
"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."
"Prisma scans things and shows all the vulnerabilities and packages that are vulnerable, and which layers, by default, have vulnerabilities. So developers can easily go into the package or a particular layer and make changes to their code. It's very transparent."
"The reporting, dashboarding, and filtering capabilities which provide reports we can present to our senior staff are the most helpful features of Prisma Cloud (Annual Contract)."
"The visibility on alerts helps you investigate more easily and see details faster."
"The most valuable feature of Prisma Cloud by Palo Alto Networks is the CSPM, which we use the most. Additionally, the investigation and alerts are useful, and the creation of queries."
 

Cons

"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"It can be improved in its support response. They usually take up to seven days to resolve the issue."
"Getting new guys trained on using the solution requires some thought. If someone is already trained on Palo Alto then he's able to adapt quickly. But, if someone is coming from another platform such as Fortinet, or maybe he's from the system side, that is where we need some help. We need to find out if there is an online track or training that they can go to."
"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."
"One of the requests is that Prisma Defender for the ECS solution is only supported for Linux. It does not support Windows."
"We face some GUI issues related to new permissions for AWS. So far, we don't have any automation to complete them through the GUI. We have to manually update the permissions. Our customers have faced some issues with that."
"When it comes to compliance, the issue is that when we are exporting the reports, there is only a single compliance option. If I need to report on multiple compliance requirements, that feature isn't available. For example, I made a single report for ISO 27000 but I can't correlate it with GDPR."
"For some custom policies, we need more features."
"The pricing for the solution needs improvement."
"Currently, custom reports are available, but I feel that those reports are targeting just the L1 or L2 engineers because they are very verbose. So, for every alert, there is a proper description, but as a security posture management portal, Prisma Cloud should give me a dashboard that I can present to my stakeholders, such as CSO, CRO, or CTO. It should be at a little bit higher level. They should definitely put effort into reporting because the reporting does not reflect the requirements of a dashboard for your stakeholders. There are a couple of things that are present on the portal, but we don't have the option to customize dashboards or widgets. There are a limited set of widgets, and those widgets don't add value from the perspective of a security team or any professional who is above L1 or L2 level. Because of this, the reach of Prisma Cloud in an organization or the access to Prisma Cloud will be limited only to L1 and L2 engineers. This is something that their development team should look into."
 

Pricing and Cost Advice

"CoreOS Clair is open-source and free of charge."
"Prisma Cloud is quite scalable. In our current licensing model, we're able to heavily extend our cloud workload and onboard a lot of customers. It really helps, and it is on par with other solutions."
"The cost was not on the higher side. Overall, the cost gets recovered with its implementation."
"You can expect a premium price because it is a premium quality product by a leading supplier."
"Prisma Cloud by Palo Alto Networks has helped the company save some money. Cost-wise, it's okay."
"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 pricing is competitive; for the most part, the security firms have similar prices."
"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."
