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

"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 vulnerability management feature is the one I like the most because it provides a clear picture of all vulnerabilities."
"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 would rate Qualys TotalCloud ten out of ten."
"Qualys TotalCloud fulfills all these needs."
"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."
"While automatic inventory detection upon connection is a helpful feature, a truly valuable capability would be assessing an environment's security posture against Azure and CIS best practices."
"In my opinion, this is the best tool."
"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."
"It has helped us build confidence in our security and compliance. Prisma Cloud enables us to implement all these SOC 2 compliances and check the security. It provides visibility and control regardless of how complex our environment is."
"The product provides very good network security."
"The product is quite good for providing multi-clouds or cross-cloud security from a single-pane -of-glass."
"With the query language, we can analyze logs and find out which IPs are malicious. It also provides a graphical representation. It provides the overall visibility and how the traffic is flowing. We can see where the malicious IP is and whether it is an insider threat or an outsider threat."
"Prisma Cloud provides the needed visibility and control regardless of how complex and distributed the cloud environments become."
"This solution provides us with a single tool to protect all of our cloud resources and applications without having to manage and reconcile different security and compliance reports."
"The two most valuable features are container security and the capability to discover workloads."
"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."
"By using Nessus, we are able to finish testing with assured results, in half the time."
"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."
"Nessus scanner is very effective for internal penetration testing."
"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 strong security provided by the product in the container environment is its most valuable feature."
"It is a scalable solution. Scalability-wise, it is a good solution."
 

Cons

"I sometimes have difficulty detecting or uninstalling certain versions of applications, which I have to do manually."
"Regarding technical support from Qualys, they respond, but the response time can be too long. Sometimes we need to wait weeks for solutions to simple questions."
"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"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."
"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."
"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."
"With the growing integration of AI, I would like Qualys to enhance its service offerings to better accommodate AI-related risks."
"I would appreciate additional integration options to connect Qualys TotalCloud with our other vulnerability management tools."
"The alignment of Twistlock Defender agents with image repositories needs improvement. These deployed agents have no way of differentiating between on-premise and cloud-based image repositories. If I deploy a Defender agent to secure an on-premise Kubernetes cluster, that agent also tries to scan my ECR image repositories on AWS. So, we have limited options for aligning those Defenders with the repositories that we want them to scan. It is scanning everything rather than giving us the ability to be real granular in choosing which agents can scan which repositories."
"The automation must continue to become much smoother."
"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."
"There are hundreds of built-in policies for AWS and Azure, but GCP and Oracle are not covered as much as AWS. There is a lot of work to do on that part. There is, obviously, a tiny bit of favoritism towards AWS because it has the most market share."
"The challenge that Palo Alto and Prisma have is that, at times, the instructions in an event are a little bit dated and they're not usable."
"We'd like to have more native integration with clouds and additional security checks in the future."
"When it comes to compliance, the issue is that when we are exporting the reports, there is only a single compliance option. If I need to report on multiple compliance requirements, that feature isn't available. For example, I made a single report for ISO 27000 but I can't correlate it with GDPR."
"It would be ideal if they could somehow reduce the deployment time."
"The solution’s pricing could be improved."
"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 stability and setup phase of the product are areas with shortcomings where improvements are needed."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"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."
