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

"I highly recommend Qualys TotalCloud to other users."
"The most valuable feature is the consolidated information that it provides from various platforms."
"Qualys TotalCloud has significantly improved our organization by automating our reporting processes, reducing the time spent on report creation from two hours to less than fifteen to twenty minutes."
"Qualys TotalCloud fulfills all these needs."
"Qualys TotalCloud has helped us view our risk structure, vulnerabilities, and security posture."
"The best part I like is the on-demand scans."
"If someone were to ask me to review Qualys TotalCloud, I would summarize it as an end-to-end solution for cloud security with visibility and governance-grade controls without needing to manage multiple disconnected tools."
"The best features in Qualys TotalCloud include the total asset management of the cloud environment. It is very easy to export the report and see the vulnerabilities related to the cloud specifically."
"The most valuable feature of the solution is its monitoring feature."
"Offers easy management with authentication and authorization features"
"One of the most valuable features I found was the ability of this solution to map the network and show you the communication between your containers and your different nodes."
"Scalability-wise, I rate the solution a nine out of ten."
"The most beneficial security feature of the product revolves around the areas of vulnerability and configuration."
"The most valuable feature is the ability to share resources."
"It is easy to install and manage."
"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."
"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 helps us secure our applications from the build phase and identify the weaknesses from scratch."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"The strong security provided by the product in the container environment is its most valuable feature."
"Nessus scanner is very effective for internal penetration testing."
"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."
 

Cons

"Qualys TotalCloud needs to enhance its scanning capabilities in the IP domain, as it currently lacks the functionality to resolve IPs to their corresponding domain names."
"TotalCloud could improve the classification of vulnerabilities. Specifically, it could enhance the categorization of what aspects fall under patches resolved by OS or software updates and what pertains to configuration adjustments."
"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."
"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."
"I sometimes have difficulty detecting or uninstalling certain versions of applications, which I have to do manually."
"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."
"The main area needing improvement is integration. Although the team is strengthening TotalCloud, integration can be enhanced with SIEM, SOAR, ITSM, and other sources."
"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."
"The testing process could be improved."
"The solution lacks features when compared to some of the competitors such as Prisma Cloud by Palo Alto Networks and has room for improvement."
"The solution's visibility and vulnerability prevention should be improved."
"I do see that some features associated with the IAST part are not included in the tool, making it an area where improvements are required."
"The initial setup is pretty complex. There's a learning curve, and its cost varies across different environments. It's difficult."
"The support and specifications need to be up to date for the cluster technologies"
"The deprecation of APIs is a concern since the deprecation of APIs will cause issues for us every time we upgrade."
"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."
"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."
"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."
"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."
"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."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
 

Pricing and Cost Advice

"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"Qualys TotalCloud is expensive."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
