Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

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.

Quotes from Members

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

Pros

"One of Qualys' best features is its categorization, which allows us to see the types of assets, their security postures, and the AI-powered version of the tool."
"While automatic inventory detection upon connection is a helpful feature, a truly valuable capability would be assessing an environment's security posture against Azure and CIS best practices."
"In my opinion, this is the best tool."
"The most valuable feature is extensibility."
"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."
"The agent and agentless scanning in TotalCloud, particularly the FlexScan method, is incredibly valuable. With traditional scanning approaches, we had to give IP ranges and whitelist IPs. All that is now simplified. FlexScan requires minimal intervention, and after configuration, it automatically collects data and performs necessary scans."
"We were able to realize its benefits within 24 to 48 hours."
"Qualys TotalCloud's most valuable feature is its agent versatility."
"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 can be used by organizations of any size."
"CoreOS Clair's best feature is detection accuracy."
"The CVEs are valuable because we used to have a tool to scan CVEs, at the language level, for the dependencies that our developers had. What is good about Prisma Cloud is that the CVEs are not only from the software layer, but from all layers: the language, the base image, and you also have CVEs from the host. It covers the full base of security."
"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."
"The most valuable features are vulnerability monitoring, serverless access, container runtime features, and Defender."
"The two most valuable features are container security and the capability to discover workloads."
"Prisma Cloud's monitoring features such as the compute compliance dashboard and the vulnerability dashboard, where we can get a clear visualization of their docker, have also been valuable. We can get layer-by-layer information that helps us see exactly where it's noncompliant. They update the dashboards quite frequently."
"From the CSPM perspective, RQL in Prisma Cloud by Palo Alto Networks is a feature where we can conduct any kind of investigation and create our own custom policies, which is really helpful because in the cloud, there are millions of assets and with RQL, we can drill down to as fine a level as per our requirement."
"As a pure-play CSPM, it is pretty good. From the data exposure perspective, Prisma Cloud does a fairly good job. Purely from the perspective of reading the conflicts, it is able to highlight any data exposures that I might be having."
"Prisma Cloud also provides the visibility and control you need, regardless of how complex or distributed your cloud environments become. It helps to simplify that complexity. Now we know what the best practices are, and if something is missing we know."
 

Cons

"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."
"Overall, we are satisfied with it. However, the response part of the Cloud Detection and Response (CDR) module can be improved. It is not yet in place according to requirements; it is not completely available even though the module has been released."
"In a future release, I suggest that zero-day vulnerabilities should be predicted in advance using AI technologies. The system is not 100% secure yet, so proactive threat hunting could be enhanced to be more proactive than the current system."
"The areas in the solution that have room for improvement include the UI/UX design, which should be improved, and they should integrate more artificial intelligence into the product."
"Regarding technical support from Qualys, they respond, but the response time can be too long. Sometimes we need to wait weeks for solutions to simple questions."
"The onboarding process is a bit difficult. In the initial phase, it is very difficult to understand the features, what the dashboard contains, and what criteria they are using."
"I would like the ability to disable certain default built-in policies as they can be misleading when creating dashboards. That is the top one."
"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."
"It can be improved in its support response. They usually take up to seven days to resolve the issue."
"An area for improvement is that CoreOS Clair doesn't provide information about the location of vulnerabilities it detects."
"I don't think their SaaS offering is adoptable by large enterprises like ours, in every case."
"The regional cost of Prisma Cloud in South Africa is high and could be improved."
"The automation capabilities are growing each day, but the problem is that the updates are not that frequent. There are some services on Amazon that have come out with updates, and Azure is also getting up to date. But Prisma takes some time to follow. There's a time gap that Prisma inherits from these clouds. I understand why it takes some time, but that time should be reduced."
"In terms of improvement, there are some small things like hardening and making sure the Linux resources are deployed well but that's more at an operational level."
"The integration of the Compute function into the cloud monitoring function—because those are two different tools that are being combined together—could use some more work. It still feels a little bit disjointed."
"Some of the usability within the Compute functionality needs improvement. I think when Palo Alto added on the Twistlock functionality, they added a Compute tab on the left side of the navigation. Some of the navigation is just a little dense. There is a lot of navigation where there is a tab and dropdowns. So, just improving some of the navigation where there is just a very dense amount of buttons and drop-down menus, that is probably the only thing, which comes from having a lot of features. Because there are a lot of buttons, just navigating around the platform can be a little challenging for new users."
"Prisma's notifications aren't up to industry standards."
"The access controls for our bank roles were not granular enough. We needed specific people to do particular actions, and we often had to give some people way too much access for them to be able to do what they needed in Prisma. They couldn't do their jobs if they didn't have that level of access, so other people had to do that part for them. It would help to have more granular role-based access controls."
 

Pricing and Cost Advice

"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"I am not sure about the pricing. From what I understand, it is a bit on the higher side, but I do not have the exact numbers."
"TotalCloud's price is about right where I would expect it to be."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"The cost is high, but it meets our organizational needs."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"CoreOS Clair is open-source and free of charge."
"I wouldn't mind if it were cheaper. We are spending a fair amount of money on Prisma Cloud."
"Prisma Cloud by Palo Alto Networks carries a higher cost, but its enhanced security measures justify the expense."
"Prisma Cloud by Palo Alto Networks is a highly expensive solution."
"Prisma Cloud licensing works on credits."
"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."
"The pricing is reasonable."
"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."
"Prisma Cloud is affordable."
