Risk-based triage has transformed container security and now prioritizes high-impact threats
The best features Qualys TotalCloud offers currently include managing cloud infrastructure and container security while facing major challenges such as alert fatigue. Traditional vulnerability scanners flag hundreds of CVEs on short-lived Kubernetes containers, some of which have no internet exposure or are gone before we can even triage them. I leverage Qualys TotalCloud to move beyond static CVSS. I use it to implement runtime exposure, correlation risk reprioritization, and shift-left integration. This notifies developers to fix a base image upstream rather than patching live ephemeral instances. In my work with cloud and container security, the biggest operational hurdle was alert fatigue. I use Qualys to shift left from static CVSS severity to context-aware risk prioritization. I correlated raw vulnerability data with real-time risk factors such as public network exposure, active runtime execution, or overly permissive IAM roles. This allows us to immediately drop the priority of isolated containers and escalate lower-severity CVEs that sit on an exposed, high-risk path. We can map these findings directly back to our CI/CD pipelines so developers can patch the root base images upstream. We have drastically cut down the signal-to-noise ratio, saved a lot of manual hours doing triage work, and ensured engineering effort goes directly towards high-impact risk reduction.

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

"The scalability is good as well. I would rate it ten out of ten."
"The vulnerability management feature is the one I like the most because it provides a clear picture of all vulnerabilities."
"TotalCloud has been excellent in providing us with immediate access to all the products and features we need, such as CSPM, TruRisk Insights, and compliance reports, including CIS and HIPAA."
"Qualys TotalCloud is an excellent platform, and the beauty of the platform is that we can get all the vulnerabilities, see all the reports in a single dashboard, view them segregated, and easily learn about critical, high, and medium findings with appropriately provided remediation steps."
"Generally, Qualys is very good at detections, whether on cloud or on-prem, and the agent allows deployment on both infrastructures, providing continuous monitoring of your assets, which is a key selling point for us."
"With TotalCloud, we can scan through the API. If we are not able to deploy cloud agents on the machine, we can use the API."
"I would definitely recommend it because it is easy to handle any cloud resources."
"TotalCloud offers a comprehensive suite of features, including EDR, XDR, and TrueRisk, providing a centralized platform for managing vulnerabilities and security risks."
"It scans our containers in real time. Also, as they're built, it's looking into the container repository where the images are built, telling us ahead of time, "You have vulnerabilities here, and you should update this code before you deploy." And once it's deployed, it's scanning for vulnerabilities that are in production as the container is running."
"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."
"The Twistlock vulnerability scanning tool is its most valuable feature. It provides us insight into security vulnerabilities, running inside both on-premise and public cloud-based container platforms. It is filling a gap that we have with traditional vulnerability scanning tools, where we don't have the ability to scan inside containers."
"It gave us visibility into and control over complex cloud environments, which helped us feel better about our security and secure the environment with the clinical data."
"This solution will ensure that we've got a more secure environment, mitigating any sort of bad actors coming in and either destroying or disrupting the environment."
"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."
"Prisma Cloud's real-time detection and monitoring of our entire system is the most useful."
"We were pleased with Prisma's custom and built-in reports. We could go into the dashboard and see all these notifications telling us which subscriptions didn't have TLS 1.2 enabled. The security controls were the most valuable features."
"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."
"The strong security provided by the product in the container environment is its most valuable feature."
"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."
"It is a scalable solution. Scalability-wise, it is a good solution."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"By using Nessus, we are able to finish testing with assured results, in half the time."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
 

Cons

"The vulnerability part is good, but the policy compliance module needs improvement because it involves a lot of manual work. Specifically, the remediation part of the controls requires enhancements."
"Regarding improvements to Qualys TotalCloud, I suggest that user navigation can be enhanced because initially, many users found it complicated and had trouble understanding the platform due to information being spread across multiple tabs."
"One of the things that could be improved is the alerts. Qualys is a fantastic tool, especially with the TruRisk feature, but one challenge that most leaders face involves alert fatigue."
"It has been working very well, but it would be helpful if the dashboard could generate reports tailored to specific compliance needs. For example, in India, we have to comply with RBI and SEBI guidelines. It w"
"There is room for improvement in vulnerability scanning, particularly for PaaS environments. Currently, Qualys does not have full access to these instances, which limits its effectiveness."
"Their customer support needs improvement."
"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"TotalCloud could improve its scanning of niche devices like Wi-Fi dongles and USB modems because they are often untested. It covers everything else, like laptops, mobile devices, and Bluetooth IoT devices. They can improve on the small IoT devices because hackers and testers use these."
"Prisma Cloud is very comprehensive, but there should be better support for the customization of the reports. If Palo Alto can have more customized reports available or give an option to the users to customize the reports, that would be great."
"One major observation is that it is not possible to implement Prisma Cloud on-premises. This is the limitation. Prisma Cloud itself is on a cloud. It is sitting on AWS and Google Cloud. It is a SaaS solution, but some of my clients have a local regulatory requirement, and they want to install it locally on their premises. That capability is not there, but government entities and ministries want to have Prisma Cloud installed locally."
"More documentation with real-world use cases would be helpful."
"Sometimes, when you assign subnets to regions, the IP address will jump from one location to another because it will automatically change substantially. Then, we need to add those IP subnets to our firewall for existing access. The need to update those subnets potentially causes maintenance or access issues. So far, we can only provide bigger customers with six subnets, and a small company may not be able to access those services."
"Sometimes, on the Azure side, there are issues. Some errors aren't being found on Prisma Cloud."
"A better correlation between the multiple products Prisma Cloud contains would be crucial. It would reduce the time spent looking at reports and enable you to get all the actionable insights across products. I think that Palo Alto is working on it, but they need to work faster because it doesn't make sense to have all these products in a single pane of glass without any correlation between them."
"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."
"This solution is more AWS and Azure-centric. It needs to be more specific on the GCP side, which they are working on."
"The stability and setup phase of the product are areas with shortcomings where improvements are 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."
"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."
"The initial setup is highly complex."
"I feel that in certain areas this product has false positives which the company should work on."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"The solution’s pricing could be improved."
 

Pricing and Cost Advice

"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"TotalCloud's price is about right where I would expect it to be."
"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."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"Its price seems higher compared to other tools, but it is worth it. If they could adjust the pricing and make it comparable with other tools, that would be great."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"The pricing and licensing are expensive compared to the other offerings that we considered."
"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."
"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 good. They gave us some good discounts right at the end of the year based on the value that it brings, visibility, and the ability to build in cloud, compliance, and security within one dashboard."
"The licensing cost is a bit high on the compute side."
"Prisma Cloud licensing works on credits."
"Regarding Prisma Cloud's pricing, we started small, and then we just kept on growing."
"In general, Prisma Cloud is much cheaper than cloud-native services."
"The solution's pricing is neither cheap nor very expensive."
"The product does not operate on a pay-per-license model."
"I rate the tool's pricing a three out of ten."
"I rate the product’s pricing a six out of ten."
"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."
