IT Security Expert at Alior Bank S.A.
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.

Provides network mapping feature for visualizing container communication but complex setup
There is room for improvement in the setup process. All these tools come down to how you're integrating into your environment and having good knowledge of the tool. So that's the biggest problem with all these security tools – you gotta have knowledgeable people to build, integrate, and really flesh them out in your environment to make them work as they should.

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

"Qualys TotalCloud provides a single, prioritized view based on requirements such as identifying the most vulnerable assets and calculating the average time to remediate vulnerabilities."
"I found the initial setup user-friendly."
"Qualys TotalCloud's most valuable feature is its agent versatility."
"Qualys TotalCloud fulfills all these needs."
"I highly recommend Qualys TotalCloud to other users."
"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."
"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."
"By integrating TotalCloud, we have significantly reduced vulnerabilities in our deployment pipeline."
"I am impressed with the tool's visibility."
"The most beneficial security feature of the product revolves around the areas of vulnerability and configuration."
"I like virtualization and all those tools that come with OpenShift. I also like Advanced Cluster Management and the built-in security."
"Segmentation is the most powerful feature."
"The most valuable feature of the solution is its monitoring feature."
"Scalability-wise, I rate the solution a nine out of ten."
"The benefit of working with the solution is the fact that it's very straightforward...It is a perfectly stable product since the details are very accurate."
"It is easy to install and manage."
"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."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"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."
"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 solution shows you the exploitable vulnerabilities and helps you prioritize."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
 

Cons

"Qualys TotalCloud's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"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."
"I think Qualys TotalCloud needs to improve its handling of zero-day vulnerabilities and supply chain management because modern ransomware attacks not only target prime critical infrastructures but also the supply chain system."
"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."
"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."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"Red Hat is somewhat expensive."
"They're trying to convert it to the platform as a source. They are moving in the direction of Cloud Foundry so it can be easier for a developer to deploy it."
"The tool's command line and configuration are hard for us to understand and make deployment complex. It should also include zero trust, access control features and database connectivity."
"The testing process could be improved."
"The solution's visibility and vulnerability prevention should be improved."
"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."
"The initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."
"The solution's price could be better."
"The solution’s pricing could be improved."
"The initial setup is highly complex."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"I feel that in certain areas this product has false positives which the company should work on."
"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."
"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."
"Tenable.io Container Security should improve integration modules. It should also improve stability."

"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
