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.

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 vulnerability management feature is the one I like the most because it provides a clear picture of all vulnerabilities."
"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."
"I would definitely recommend Qualys TotalCloud to other users."
"The most valuable feature is extensibility."
"The dashboards are particularly valuable as they offer a comprehensive view of the environment, highlighting any misconfigurations."
"I appreciate TotalCloud's real-time protection and remediation features. The remediation options include automated one-click remedies and custom changes that help manage vulnerabilities efficiently."
"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."
"I found the initial setup user-friendly."
"It is user-friendly. It has a good look and feel and reporting structure. It provides a single pane of glass. These are the things that I like."
"My favorite feature is the CWPP module. We can define various kinds of rules for vulnerabilities, incidents, or suspicious activities."
"It provides good visibility and control regardless of the complexity."
"Prisma Cloud's most valuable asset is its ability to provide detailed visibility into container activity."
"One feature we like is the amount of data Prisma gives us. Some infrastructure and platform vulnerabilities that in the cloud are hard to detect, and we were unaware of some of these. It's critical to shed light on these. For example, you create virtual machines and forget about them, but when you revisit them, some vulnerabilities may be detected."
"The most valuable features of Prisma Cloud are its cloud security posture management and cloud workload protection capabilities."
"Prisma Cloud provides the needed visibility and control regardless of how complex and distributed the cloud environments become."
"It has helped us understand the dynamic topology of our containers, and manage security through the application of policies that our pipelines apply straight from Git."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"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 strong security provided by the product in the container environment is its most valuable feature."
"By using Nessus, we are able to finish testing with assured results, in half the time."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"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."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
 

Cons

"It is already perfect, but they can bring some newer dashboards and customization options for the dashboard. It would be great to be able to include on-prem assets on the dashboard."
"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."
"Qualys TotalCloud has the potential to improve by integrating a hybrid platform for comprehensive management of both on-premises and cloud infrastructures."
"Their support could be improved."
"The support is not up to the mark and seems to be overburdened."
"We would like to see Windows-based sensors available in Qualys, as this would make the platform more versatile and support a broader range of environments."
"The response part of the Cloud Detection and Response (CDR) module can be improved."
"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."
"A couple of exporting functionalities should be more user-friendly because if I want to export something, I can get a lot of data visible to that particular CSV."
"Prisma's notifications aren't up to industry standards."
"I don't think their SaaS offering is adoptable by large enterprises like ours, in every case."
"More documentation with real-world use cases would be helpful."
"We identified two things that we felt would be great to have, but they are under NDA. So, I can't disclose them. Other than those two things, we identified a generic bug in the secret key management service on AWS that needs to be fixed. We reported it to them, and we want them to fix it."
"The Fargate security microservice that's running doesn't support blocking features, which would be helpful. Another issue is the lifecycle. It isn't easy to upgrade if we have a console in Fargate."
"The UI could use some improvement; we usually find the information we're looking for, but what fields can be clicked on and what workflow to follow to get the required information is not always evident. Sometimes we're all over the place, clicking around to drill in and uncover the alert and investigation details we're looking for."
"The automation must continue to become much smoother."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"The initial setup is highly complex."
"I feel that in certain areas this product has false positives which the company should work on."
"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."
"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."
"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."
