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 most valuable feature is the consolidated information that it provides from various platforms."
"Qualys TotalCloud's most valuable features are its security capabilities that help identify and mitigate risk factors."
"Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution."
"By integrating TotalCloud, we have significantly reduced vulnerabilities in our deployment pipeline."
"The scalability is good as well. I would rate it ten out of ten."
"Qualys TotalCloud is overall the best tool available in the market for scanning purposes."
"I depend heavily on the reports that I have from this tool."
"I appreciate Qualys TotalCloud's ability to onboard any type of device with ease, including containers."
"The CWP module, runtime protection, and WAAS API are valuable."
"Prisma Cloud offers robust runtime scanning capabilities, which is beneficial for security teams."
"The most valuable feature of Prisma Cloud for our clients is CSPM, as it helps clients gain visibility into all the assets with their cloud providers."
"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."
"In the GlobalProtect module, we can easily guide users experiencing connection issues through the notification column."
"Most of the customers we are tackling have different tools and solutions, like Qualys, Nessus, and vulnerability management assessment solutions. There are plugins for them, and we can integrate Prisma Cloud with them. We can enrich our telemetry with their data and use the predefined correlation rules in Prisma Cloud. That means we have that work done in seconds."
"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."
"It has a feature for customized security policy. I implement it in banking, health insurance, and other sectors, and every organization has its own customized policies and procedures. In Prisma Cloud, you can customize policies, and based on that, you can do monitoring."
"Nessus scanner is very effective for internal penetration testing."
"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."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"It is a scalable solution. Scalability-wise, it is a good solution."
"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."
"By using Nessus, we are able to finish testing with assured results, in half the time."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
 

Cons

"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"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."
"There is a lack of data segregation according to criticality or inventory."
"There should be improvement from a dashboard perspective when collecting and showcasing data to lead management."
"In my opinion, what can be improved in Qualys TotalCloud includes pricing and container scanning."
"Their support could be improved."
"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."
"In TotalCloud, I would suggest improvements in policy checks to cater to various inventory types like VPCs, subnets, S3 buckets, or IAMs. There is a lack of data segregation according to criticality or inventory."
"Today, I won't recommend Palo Alto Prisma to someone because I'm not confident about their support."
"One thing that is missing is Cloud Run runtime security—serverless. That would be great to have in the tool. It's not that easy to have Cloud Run in specific environments."
"The solution does not currently support servers for GCP."
"The Palo Alto support needs to improve."
"The feedback that we have given to the Palo Alto team is that the UI can be improved. When you press the "back" button on your browser from the Investigate tab, the query that you're working on just disappears. It won't keep the query on the "back" button."
"I have some challenges customizing and personalizing some of the capabilities in the CSPM in terms of new policies and services. We have to reconfigure and rebuild the CSPM."
"It does not provide runtime security or protection for Windows Server. It is currently lacking in terms of Windows environment."
"I would like to see the inclusion of automated counter-attack, although this is probably illegal."
"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."
"The initial setup is highly complex."
"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."
"I feel that in certain areas this product has false positives which the company should work on."
"The solution’s pricing could be improved."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"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."
 

Pricing and Cost Advice

"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"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."
"Although Qualys TotalCloud is relatively expensive due to its unique automation features, its cost-effectiveness is rated an eight out of ten, with ten being the most costly."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"The cost is high, but it meets our organizational needs."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
"If a competitor came along and said, "We'll give you half the price," that doesn't necessarily mean that's the right answer, at all. We wouldn't necessarily entertain it that way. Does it do what we need it to do? Does it work with the things that we want it to work with? That is the important part for us. Pricing wasn't the big consideration it might be in some organizations. We spend millions on public cloud. In that context, it would not make sense to worry about the small price differences that you get between the products."
"Prisma Cloud is more expensive than some other solutions, but when we consider all of its use cases, the cost averages out."
"You can expect a premium price because it is a premium quality product by a leading supplier."
"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."
"One thing we're very pleased about is how the licensing model for Prisma is based on work resources. You buy a certain amount of work resources and then, as they enable new capabilities within Prisma, it just takes those work resource units and applies them to new features. This enables us to test and use the new features without having to go back and ask for and procure a whole new product, which could require going through weeks, and maybe months, of a procurement process."
"Prisma Cloud by Palo Alto Networks is a highly expensive solution."
"Almost all the CSPM tools are pretty expensive."
"The solution's pricing is neither cheap nor very expensive."
"I rate the product’s pricing a six out of ten."
"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 tool's pricing a three out of ten."
