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

"What I like most about Prisma Cloud is its zero-day signatures, maximum security, minimal downtime, cloud visibility, control, and ease of deployment."
"Cloud security posture management is the preferred feature among other vendors."
"We found it to be easy and flexible. We could easily configure it for our needs, and we could spread the Prisma Cloud platform to 16 countries without encountering any kind of problem."
"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 most valuable features are vulnerability monitoring, serverless access, container runtime features, and Defender."
"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."
"It also provides us with a single tool to manage our entire cloud architecture. In fact, we are using a multi-account strategy with our AWS organization. We use Prisma as a single source of truth to identify high- or medium-severity threats inside our organization."
"We haven't had an issue with the product for over a year."
"Currently, I haven't implemented the solution due to its deprecation by the site. However, I can highlight some benefits of Tenable Cloud Security, a cybersecurity solution with various features for scanning vulnerabilities in both cloud environments and on-premises container security."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"Nessus scanner is very effective for internal penetration testing."
"It is a scalable solution. Scalability-wise, it is a good solution."
"The strong security provided by the product in the container environment is its most valuable feature."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
 

Cons

"The data security model needs improvement due to integration issues with certain features and cloud providers. With Palo Alto now utilizing a tool from an Israeli startup in Prisma Cloud, the integration is slow, and some features are blocked or not supported."
"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."
"The information presented in the UI sometimes doesn't look intuitive enough."
"Prisma Cloud lags behind in terms of security automation capabilities."
"It can be too expensive for small companies."
"I don't have any specific notes for improvement; however, if they could continue to focus more on giving users the ability to create custom policies and configurations, that would be ideal."
"The UX part of Prisma's user interface could be simplified and the metrics tool should be highlighted more."
"There are hundreds of built-in policies for AWS and Azure, but GCP and Oracle are not covered as much as AWS. There is a lot of work to do on that part. There is, obviously, a tiny bit of favoritism towards AWS because it has the most market share."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"The initial setup is highly complex."
"I believe integration plays a crucial role for Tenable, particularly in terms of connecting with other products and various container solutions like Docker or Kubernetes. It seems that in future updates, enhanced integration is something I would appreciate. Currently, there is integration with Docker, but when it comes to Kubernetes or other container solutions, it appears to be a challenge, especially with on-prem scanners."
"I feel that in certain areas this product has false positives which the company should work on. They should also try to include business logic vulnerabilities in the scanner testing. Finally, the vulnerability assessment feature should be increased to other hardware devices, apart from firewalls."
"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."
"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."
"The solution’s pricing could be improved."
 

Pricing and Cost Advice

"It is fairly priced. However, its price can be better so that small banks or small organizations can afford it and adopt it to secure their environment and data."
"This solution is good for a company with at least 400 people that must be connected remotely. For smaller companies, it can be too expensive."
"Its licensing cost depends on the type of license such as the business license or the enterprise license. The enterprise license is costlier than the business license, but we get more visibility and more modules. If you have a multi-cloud environment and subscribe to each cloud's native CSPM tool, it is costly. If you are using a single tool like Prisma Cloud, with a single license, you can monitor all environments, such as Google Cloud, Azure, AWS, and Oracle Cloud. The cost of Prisma Cloud is less than the cost of subscribing to the CSPM tool of each cloud provider. This is where Prisma Cloud can save costs."
"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."
"The price for Prisma Cloud is reasonable."
"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 pricing for Prisma Cloud is high. Providing a pay-as-you-go model or pricing options tailored for medium and small enterprises could help attract more clients."
"It is an expensive tool. It is not cheap technology. It is a serious investment for any customer. Customers typically buy it together with services. In my experience, customers buying Prisma Cloud are prepared to pay for the implementation and the tool itself."
"The solution's pricing is neither cheap nor very expensive."
"The product does not operate on a pay-per-license model."
"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 product’s pricing a six out of ten."
"I rate the tool's pricing a three out of ten."
