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."
"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 most valuable features of Prisma Cloud are its cloud security posture management and cloud workload protection capabilities."
"One of the most valuable features is the compliance of RedLock, which we are using for any issues with security. It flags them and that's the primary objective of that feature."
"Configuration monitoring and alerting is the most valuable feature; it happens at the cloud's speed, allowing our development team to respond quickly. If a configuration goes against our security best practices, we're alerted promptly and can act to resolve the issue. As cloud security staff, we're not staring at the cloud all the time, and we want to let the developers do their jobs so that our company is protected and work is proceeding within our security controls."
"Its ease of integration is valuable because we need to get the solution out of the door quickly, so speed and ease matter."
"With the query language, we can analyze logs and find out which IPs are malicious. It also provides a graphical representation. It provides the overall visibility and how the traffic is flowing. We can see where the malicious IP is and whether it is an insider threat or an outsider threat."
"I find the CSPM area to be a more valuable and flexible feature."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"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."
"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."
"The strong security provided by the product in the container environment is its most valuable feature."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
 

Cons

"Though Prisma Cloud by Palo Alto Networks provides excellent security, is a pioneer in this space, and knows what it's doing, from a user perspective, it would have been better if it was a little easier to use."
"For some custom policies, we need more features."
"They should improve the user experience."
"Having auto Defender upgrades so that we do not have to upgrade Defender manually would be helpful."
"Prisma is good about compliance, and their support is excellent, but they struggle with automation and integration. They need to stay on top of the newest types of connectors. How can you connect other applications and other tools in order for this to work cohesively? That's a challenge."
"Prisma Cloud's application security capabilities should be enhanced."
"Based on my experience, the customization—especially the interface and some of the product identification components—is not as customizable as it could be. But it makes up for that with the fact that we can access the API and then build our own systems to read the data and then process and parse it and hand it to our teams."
"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."
"The solution’s pricing could be improved."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"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 stability and setup phase of the product are areas with shortcomings where improvements are needed."
"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."
 

Pricing and Cost Advice

"We are encountering some resistance in the African market regarding the cost of Prisma Cloud."
"Our licensing fees are $18,000 USD per year."
"The pricing structure is easy to understand. Depending on the use case the pricing of the solution can be different. There are not any additional costs to the standard living fees."
"The pricing and licensing are expensive compared to the other offerings that we considered."
"Prisma Cloud's licensing system functions as expected with a solid licensing infrastructure."
"Prisma Cloud is a high-end enterprise solution, making it quite expensive."
"The pricing is competitive; for the most part, the security firms have similar prices."
"Prisma Cloud is remarkably expensive."
"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."
"The product does not operate on a pay-per-license model."
"The solution's pricing is neither cheap nor very expensive."
"I rate the product’s pricing a six out of ten."
