What is our primary use case?
The main use case was identification of cloud security compliance and detection of misconfigurations (including user and service principal identity and permissions) across multi-cloud environment. Secondary use case was development of custom policies based on internal security requirements of the banking client.
For the Financial Services client, I mainly used the CSPM and Cloud Infrastructure Entitlement Management (CIEM) modules. Code Security module was integrated to a limited extent, as part of CI/CD pipeline to enable Infrastructure as Code scanning before deployment. The primary cloud platforms of this client were AWS and Azure (limited cloud presence).
I also used Prisma Cloud for a PoC for another client of mine who used Azure and Oracle cloud platforms. The evaluation included different capability set as well: in addition to CSPM, CIEM, the Cloud Workload Protection Platform (CWPP) module capabilties were evaluated.
How has it helped my organization?
Prisma Cloud provides security spanning multi-cloud environments. I have used the it for securing AWS, Azure, and Oracle Cloud environments.
Main Benefit:
Increased visibility across multiple cloud platforms is the main benefit. Before implementing Prisma Cloud, cloud-native solutions were available, however they did not show all of the problems that were present. The main benefit of implementing Prisma Cloud was the increased visibility into cloud permissions of users, roles and their usage in AWS. Prisma Cloud enabled that visibility and enabled the teams to see misconfigurations that were present in the cloud environment and start addressing them.
In addition to the identity part, Prisma Cloud provided some foundational visibility into the cloud workload misconfigurations. While a lot of false positives were identified, after the initial alert triage, the result was a lot of valuable insights to various misconfigurations.
Threat Detection:
In regards to threat detection, for the other client where I carried out the PoC, I have done some testing after onboarding the Cloud Workload Protection module. Malware samples, EICAR files were uploaded to the test environment, and Prisma Cloud detected all of it.
Compliance Monitoring:
During the PoC for one of the clients, I have used cloud compliance monitoring of Prisma Cloud CSPM as well as CWPP modules, and found some discrepancies between the two. Some built-in compliance frameworks are available for the CSPM module, however not available in CWPP module. Cloud compliance monitoring and reporting can be done, however, there were discrepancies on what built-in compliance policies and frameworks are available in different modules. Custom security and compliance policies can be created and were used extensively in the Financial Services customer's project.
Hybrid Environments:
In regards to hybrid environments, I have only used it for Kubernetes deployment during the PoC. Kubernetes can be hosted on-premises or used as a managed service offered by any of the major cloud providers. I suppose that covers the hybrid use case. I have not used agent-based installations on anything other than Azure Kubernetes Service (AKS). In my experience, this part is where Prisma Cloud stands out from the competitors. It demonstrated easy onboarding as well as comprehensive visualisation of Kubernetes workloads running on the cluster, vulnerability and malware detection capabilties.
Features That Require Client's Time Investment:
The initial "alert burndown", as Palo Alto Networks themselves call it. The alert triage and policy tuning phase where the security team goes in, reviews the initial findings, updates the policies and/or creates custom ones, and disables some of the policies that are not relevant so that internal teams are not overloaded. That has required a significant amount of time invested. For the Financial Services customer, Code Security module has also been deployed (Checkov integration into the CI/CD pipeline). It took a lot of time to tune Code Security policies, because it performs static analysis of Infrastructure as Code files. It can produce a lot of false positives, especially in cases where Terraform modules are used in the infrastructure code.
What is most valuable?
CIEM module has provided most value for the Financial Services client, it identified the overly-permissive roles and users who can assume these roles. Without CIEM, these misconfigurations would have been difficult to spot.
What needs improvement?
Prisma Cloud is based on acquisitions, which is both a pro and con. Palo Alto Networks made it fast to the market, however, they are now catching up and trying to integrate their acquired solutions into the Prisma Cloud platform.
Ability to See the Full Picture of Risk:
The main hurdle from user standpoint for me was the ability to see the full picture without effort. This was still true when I last used it in April 2024. A user has to switch between the modules to get different pieces of information. To see the CWPP data, you need to switch to that module. To see the code security part, you need to switch to the Code Security module. It is the same story with CSPM. At least two competitors of Prisma Cloud offer a better experience when it comes to visualisation of data. They show the full view of a risk (what Prisma Cloud claims to do, but does not do well). The good news - Prisma Cloud is catching up and has slightly improved over time.
The User Interface:
I simply didn't like the first one, then they changed it and made it even worse. But that might be a matter of preference, not an actual negative.
Ease of Building Custom Policies:
The RQL and APIs are poorly documented, which significantly complicates building of custom policies. There should be no expectation that someone without a clue on how cloud services are constructed can effectively write custom policies using any of CNAPP offerings available in the market, however, this is especially true for Prisma Cloud. When we compare Prisma Cloud with competitors, for sure, it is much more difficult to create custom policies because the APIs themselves are not that well documented. When discussing this topic with their Professional Services engineer who was assigned to the project, the person admitted that at times it is trial and error path to building custom policies. The JSON preview feature did help to improve it, but you still need to guess which API to pick to get what you want.
With all that said, Prisma Cloud offers a powerful custom policy building engine, and when a skilled person works on it, they can do advanced queries, joining the results of different APIs for example and using them to futher build the custom policy.
Quality Control Issues:
During the year-long project while working on alert triage, I encountered a number of CIEM policies that were displaying odd results, which were reported to the Customer Success team and were addressed with an update. This was an indicator that these built-in policies have not been tested that much, since the issue that was identified was impacting all users.
For how long have I used the solution?
I've used Prisma Cloud for over a year.
I used it for two clients of mine. One client was in Financial Services sector, a bank, and that was where I prepared a solution integration design for Prisma Cloud and later on, supported the integration itself, including the alert review and handover of the operational tasks to the engineering team. For the bank, I started with integration planning (HLD, then LLD) and internal security review process in December 2022, implementation after three months, and finished the project in March 2024. It has been over a year overall of using the solution.
The second use case involved conducting a month-long Proof of Concept (PoC) for another client in the Engineering & Manufacturing sector, focusing on testing of Prisma Cloud CSPM,CIEM and CSWPP capabilities for Azure and Oracle cloud platforms.
What do I think about the stability of the solution?
It is stable in the sense of being available so that users can log in and use the solution.
However, a colleague working on the same project in security engineering team has noticed some of Prisma Cloud behaviour using search functionality, which returned different set of results each time same, unmodified query was being executed. This could be a single example of such instability, but it was something odd to observe. This issue has been raised to Prisma Cloud support team, however, I am not aware of the outcome.
What do I think about the scalability of the solution?
Scalability was perfect. We had no issues with it.
How are customer service and support?
I would rate their support a five out of ten. The professional services engineer was excellent. The sales and technical account management team was excellent. The solution architect who supported us also was great.
However, for the customer success part, we had to replace an engineer who was originally assigned to support us. In many cases, the customer success team struggled to answer questions which we already researched reading available documentation. Most of the time we got answers from the solution architects. After replacing the engineer who was originally assiged to us, the situation improved slightly, but I would still expect a more capable team supporting the product. My understanding was that the customer success team struggled getting the right information as well.
After we escalated some of the problems to the TAM, issues were resolved relatively quickly.
How would you rate customer service and support?
Which solution did I use previously and why did I switch?
Before using Prisma Cloud, I used Checkpoint's Dome9 (in 2020-2021), as well as Microsoft Defender for Cloud. Main reason of selecting Prisma Cloud was multi-cloud capabilities, high number of built-in policies and capability to build custom policies.
If you mainly use AWS, and also use Kubernetes - Prisma Cloud may be a really good option. If you use Azure and Oracle cloud - there might be better alternatives out there.
I would strongly recommend to test it in your own environment, by onboarding a few accounts in Test/Dev and try to work on the findings - this will give you a better understanding of the tool. If you plan enabling your dev team to work on it, involve them in the PoC/PoV testing and get their feedback (this will likely show how much time security team will need to invest into supporting the dev team as well).
How was the initial setup?
In my opinion, it is very straightforward. A few months back, I deployed Prisma Cloud and two other CNAPP tools in a PoC setting, and I can say that Prisma Cloud was the easiest one to onboard the cloud environments, as well the Kubernetes cluster using their provided Helm chart template. Despite my prior experience with Prisma Cloud, the onboarding documentation is well-written. A small exception can be made for SSO and SAML configuration, for which Prisma Cloud did not have public documentation article available, however, the Customer Success team has provided an instruction document for the configuration.
The cloud environment onboarding duration depends on whether the person deploying it has all permissions on the cloud side. If all permissions are in available, you can deploy it within 15 minutes. It is so easy. If AWS Organizations are used, after onboarding Prisma Cloud sees all the accounts that are part of that Organization. Same applies for Azure when a Tenant Root Group is onboarded - all subscriptions that belong to it, as well as all resource groups and resources part of it are monitored automatically. Some results show up immediately, while all misconfigurations are visible the next day, because it takes time for the tool to ingest all the cloud wokrloads, build the inventory and produce findings.
If we talk about onboarding Kubernetes clusters, the time it takes depends on the client's environment. Onboarding a single cluster is a matte of minutes. Overall, it can take some time, but is really straightforward using the provided Helm chart template.
Maintenance of the Integration:
Any CNAPP solution requires maintenance. This is because new cloud services are being rolled out by the cloud providers. For a CNAPP solution to be able to read those new resources and their configurations, permissions on the cloud provider's side need to be added to the roles that the CNAPP solution is using. As time passes and new cloud services are rolled out, missing permissions show up in Prisma Cloud, indicating what needs to be updated on the cloud provider's side.
The other item is the review of new built-in policies. These new policies may produce some false positives. From time to time, this needs to be reviewed by the security team. Some adjustments might be required there.
Last big item is the new features of Prisma Cloud that are being introduced. If these new features are added and if a client is using a custom and granular RBAC model to access Prisma Cloud, these permissions need to be revised and updated so that users can access and use those new capabilities.
What about the implementation team?
For overall integration I have been working as a consultant (external) for the Financial Services customer. In this project, we had Professional Services consultant provided by Palo Alto Networks as part of the contract, who supported custom policy development. However, most of custom policies were developed by external consultants who were hired for the task.
The project also had Customer Success team support who offered training sessions.
I would rate the Professional Services team very highly. However, the Customer Success team fell short of expectations, to the extent that we requested a replacement for our customer success engineer.
What was our ROI?
As a cloud security specialst, if I did not have such tool, I would write a bunch of scripts to query the cloud APIs and get the data that I need. Prisma Cloud does that for us. With that said, any CNAPP tool offers such capability.
We have not estimated the actual return on investment in terms of quantifying it. From a security standpoint, with help of Prisma Cloud we found a number of misconfigurations that were not detected previously, however it is difficult to quantify the ROI. We may have prevented a security breach with remediation of the findings, however, any accurate likelihood and impact estimation would also be challenging.
What's my experience with pricing, setup cost, and licensing?
The pricing is on par with the competitors.
Which other solutions did I evaluate?
A few competitor solutions have been evaluated during the selection for the Financial Services client. However, the selection process was made by former security architects who from whom I took over the project for integration planning and implementation as they departed the client's organisation.
For the other client, where I tested Prisma Cloud in a PoC in 2024 April on Azure and Oracle cloud use case, unfortunately, Prisma Cloud has not been chosen as CNAPP solution.
What other advice do I have?
Pros:
I would recommend Prisma Cloud to those who are cloud-native. Specifically, Kubernetes is what Prisma Cloud does really well because they acquired Twistlock which was an excellent tool for the task.
Another big point would be for those with many internal/custom security requirements. Despite the challenge of undocumented APIs, if you have a dedicated cloud security engineering team, they can take advantage of the RQL policies for cloud security posture management and compliance monitoring.
Cons:
If you want full visibility of risk, without needing to proactively look for issue, and need to switch between the contexts within Prisma Cloud, I may not recommend it. If visibility is your priority, there may be better alternatives out there. If the client is a small enterprise and wants to prioritize the tool being used by the developers, there are stronger competitors out there, as to my observation, Prisma Cloud is built for those with dedicated cloud security roles in mind who will spend the time tuning the tool and customising the policies.
Data Protection / GDPR concerns:
The main client where I used Prisma Cloud and worked on the integration is a bank in Europe, and they are very sensitive to data protection and GDPR, which has added some constraints to the whole integration. This would be true for any other CNAPP solution (deployed in a full SaaS mode, not using an "Outpost").
If the vendor is compromised and the permissions that it has in the client's cloud environment are compromised, this could lead to a security breach and this is a risk that must be understood and accepted when deploying a 3rd party CNAPP solution. This is true for all CNAPP vendors, not only Prisma Cloud.
AI Security:
I have not used Prisma Cloud for AI security. I know they have released some AI capabilities, however, I cannot comment on it.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)
