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.

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.

SecOps program for us, as a smaller company, is amazing; they know what to look for
They could give a few more insights into security groups and recommendations on how to be more effective. That's getting more into the AWS environment, specifically. I'm not sure if that's Threat Stack's plan or not, but I would like them to help us be efficient about how we're setting up security groups. They could recommend separation of VPCs and the like - really dig into our architecture. I haven't seen a whole lot of that and I think that's something that, right off the bat, could have made us smarter. Even as part of the SecOps Program, that could be helpful; a quick analysis. They're analyzing our whole infrastructure and saying, "You have one VPC and that doesn't make a lot of sense, that should be multiple VPCs and here's why." The architecture of the servers in whatever cloud-hosting provider you're on could be helpful. Other than that, they should continue to expand on their notifications and on what's a vulnerability. They do a great job of that and we want them to continue to do that. It would be cool, since the agent is already deployed and they know about the server, they know the IP address, and they know what vulnerability is there, for them to test the vulnerability and see if they can actually exploit it. Or, once we patch it, they could double-check that it can't be. I don't know how hard that would be to build. Thinking on it off the top off my head, it could be a little challenging but it could also be highly interesting. It would also be great if we could test a couple of other features like hammering a server with 100 login attempts and see what happens. Real test scenarios could be really helpful. That is probably more something close to what they do with the SOC 2 audit or the report. But more visualization of that, being able to test things out on our infrastructure to make sure we can or can't hit this box could be interesting.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"By integrating TotalCloud, we have significantly reduced vulnerabilities in our deployment pipeline."
"The most valuable feature is the consolidated information that it provides from various platforms."
"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."
"TotalCloud offers a comprehensive suite of features, including EDR, XDR, and TrueRisk, providing a centralized platform for managing vulnerabilities and security risks."
"Qualys TotalCloud has improved our security posture."
"Qualys TotalCloud's most valuable features are its security capabilities that help identify and mitigate risk factors."
"The platform's unified view of the organization proves particularly valuable for leadership team meetings."
"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."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"It is a scalable solution. Scalability-wise, it is a good solution."
"Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning."
"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."
"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."
"The strong security provided by the product in the container environment is its most valuable feature."
"With Threat Stack, we quickly identified some AWS accounts which had services that would potentially be exposed and were able to remediate them prior to release of products."
"There has been a measurable decrease in the meantime to remediation, by 95 percent."
"Threat Stack has connectivity."
"Every other security tool we've looked is good at containers, or at Kubernetes, is good at AWS, or at instance monitoring. But nobody is good at tying all of those things together, and that's really where Threat Stack shines."
"It is a fantastic tool that gives us a level of comfort knowing that there is not only something that's watching, something that can alert and detect, but also knowing that there's an outsourced operation center that can be an auxiliary part of our security team."
"The rules are really great. They give us more visibility and control over what's being triggered. There's a large set of rules that come out-of-the-box. We can customize them and we can create our own rules based on the traffic patterns that we see."
"It has been quite helpful to have the daily alerts coming to my email, as well as the Sev 1 Alerts... We just went through a SOX audit and those were pivotal."
"Technical support is very helpful."
 

Cons

"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"The cost of Qualys TotalCloud is high and could be more competitive."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"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."
"I would like the ability to disable certain default built-in policies as they can be misleading when creating dashboards. That is the top one."
"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."
"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"Their customer support needs improvement."
"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."
"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 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 initial setup is highly complex."
"The solution’s pricing could be improved."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"The API - which has grown quite a bit, so we're still learning it and I can't say whether it still needs improvement - was an area that had been needing it."
"It's too expensive, but I'm always going to say that. It is very expensive compared to some other products."
"Some features do not work as expected."
"They could give a few more insights into security groups and recommendations on how to be more effective."
"The reports aren't very good. We've automated the report generation via the API and replaced almost all the reports that they generate for us using API calls instead."
"I would like further support of Windows endpoint agents or the introduction of support for Windows endpoint agents."
"The one thing that we know they're working on, but we don't have through the tool, is the application layer. As we move to a serverless environment, with AWS Fargate or direct Lambda, that's where Threat Stack does not have the capacity to provide feed. Those are areas that it's blind to now..."
"The solution’s ability to consume alerts and data in third-party tools (via APIs and export into S3 buckets) is moderate. They have some work to do in that area... The API does not mimic the features of the UI as far as reporting and pulling data out go. There's a big discrepancy there."
 

Pricing and Cost Advice

"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"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."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"Qualys TotalCloud is expensive."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"I rate the tool's pricing a three out of ten."
"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 product’s pricing a six out of ten."
"The solution's pricing is neither cheap nor very expensive."
"The product does not operate on a pay-per-license model."
"It is a cost-effective choice versus other solutions on the market."
"Pricing seems to be in line with the market structure. It's fine."
"I'm happy with the amount that we spend for the product that we get and the overall service that we get. It's not cheap, but I'm still happy with the spend."
"What we're paying now is somewhere around $15 to $20 per agent per month, if I recall correctly. The other cost we have is SecOps."
"It came in cheaper than Trend Micro when we purchased it a few years ago."
"It is very expensive compared to some other products. The pricing is definitely high."
"We find the licensing and pricing very easy to understand and a good value for the services provided."
