Sr Security Engineer at a tech vendor with 5,001-10,000 employees

Risk-based triage has transformed container security and now prioritizes high-impact threats

The best features Qualys TotalCloud offers currently include managing cloud infrastructure and container security while facing major challenges such as alert fatigue. Traditional vulnerability scanners flag hundreds of CVEs on short-lived Kubernetes containers, some of which have no internet exposure or are gone before we can even triage them. I leverage Qualys TotalCloud to move beyond static CVSS. I use it to implement runtime exposure, correlation risk reprioritization, and shift-left integration. This notifies developers to fix a base image upstream rather than patching live ephemeral instances. In my work with cloud and container security, the biggest operational hurdle was alert fatigue. I use Qualys to shift left from static CVSS severity to context-aware risk prioritization. I correlated raw vulnerability data with real-time risk factors such as public network exposure, active runtime execution, or overly permissive IAM roles. This allows us to immediately drop the priority of isolated containers and escalate lower-severity CVEs that sit on an exposed, high-risk path. We can map these findings directly back to our CI/CD pipelines so developers can patch the root base images upstream. We have drastically cut down the signal-to-noise ratio, saved a lot of manual hours doing triage work, and ensured engineering effort goes directly towards high-impact risk reduction.

Runtime threat detection has improved and security teams prioritize real Kubernetes risks

The best feature Sysdig Secure offers is threat detection. The threat detection feature on Sysdig Secure stands out compared to other solutions I have seen or used because Sysdig sees the actual behavior inside the container or kernel and correlates it with Kubernetes infrastructure, which makes detection both earlier and more precise in a cloud-native environment. Sysdig Secure has positively impacted our organization by improving visibility into our Kubernetes environment and focusing on real risk, which has reduced alert noise, improved threat detection at runtime, and made vulnerability management more efficient by prioritizing issues that actually affect running workloads.

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

"I appreciate Qualys TotalCloud's ability to onboard any type of device with ease, including containers."

"TotalCloud provides the easiest and the best approach for cloud infrastructure management."

"The scalability is good as well. I would rate it ten out of ten."

"TotalCloud offers a comprehensive suite of features, including EDR, XDR, and TrueRisk, providing a centralized platform for managing vulnerabilities and security risks."

"CSPM is currently the most used feature, and we are enjoying the new feature, FlexScan, which is valuable for Internet-facing VMs."

"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."

"I found the initial setup user-friendly."

"Qualys TotalCloud fulfills all these needs."

More Qualys TotalCloud pros

"The log monitor is the most valuable feature."

"The proactiveness of the support has been fantastic. Every time we mention something in a meeting that we're trying to do, he proactively takes that as an investigation topic and looks into it. He'll provide the solution even though we might not have asked him to investigate it."

"Sysdig Secure has positively impacted our organization by improving visibility into our Kubernetes environment and focusing on real risk, which has reduced alert noise, improved threat detection at runtime, and made vulnerability management more efficient by prioritizing issues that actually affect running workloads."

"I see Sysdig as the most comprehensive solution in comparison to its competitors."

"We appreciate this feature, especially when combined with CD monitoring. The implementation of requested features has been remarkable, such as scanning for compliance in CRM processes for the US government. We heavily rely on this feature to assess compliance with federal requirements."

"In terms of measurable outcomes, I have seen a reduction in vulnerabilities, as Sysdig Secure can tell us how many vulnerabilities are present on a day-to-day report basis, which has improved our efficiency by more than 50% and helps us stay compliant with necessary regulations."

"I have not seen any stability issues so far."

"The most valuable feature is the level of support that we get. Our solutions or customer success representative is very valuable. I see them as an extension of our security team."

More Sysdig Secure pros

"The capacity to respond to evidence requests from the SOX auditors has significantly improved because of this tool."

"We're using it on container to see when activity involving executables happens, and that's great."

"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."

"We find the licensing and pricing very easy to understand and a good value for the services provided."

"There has been a measurable decrease in the meantime to remediation, by 95 percent."

"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."

"There has been a measurable decrease in the meantime to remediation... because we have so many different tech verticals already collated in one place, our ability to respond is drastically different than it used to be."

"The number-one feature is the monitoring of interactive sessions on our Linux machines. We run an immutable environment, so that nothing is allowed to be changed in production... We're constantly monitoring to make sure that no one is violating that. Threat Stack is what allows us to do that."

More Threat Stack Cloud Security Platform [EOL] pros

Cons

"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."

"Qualys TotalCloud has the potential to improve by integrating a hybrid platform for comprehensive management of both on-premises and cloud infrastructures."

"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."

"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."

"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."

"The price is very expensive, actually."

"There is room for improvement in the support."

"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."

More Qualys TotalCloud cons

"The solution needs to improve overall from a CSPM standpoint since they can't compete with Wiz or Orca."

"They should make it specific with a couple of features only."

"There was a security concern related to a specific feature. While the feature itself was promising, it posed a challenge. The situation revolved around code scanning. If your source code is hosted within your own premises, say on Bitbucket, you naturally wouldn't want your code to be accessible to external parties beyond your company. Keeping your code base private is a standard practice. However, in the case of code scanning using Sysdig Secure, they copy your code to their SaaS platform. This posed an issue for us. When we inquired about this, their response acknowledged the concern. In an upcoming release, they plan to enable code scanning within your on-premises environment through the assistance of an agent. This change is already in progress. While this tool stands out compared to existing solutions in the market, it's important to note that there are still some limitations to consider. Another drawback we encountered relates to our expertise with Kubernetes. The tool can monitor Kubernetes audit logs, triggering alerts and notifications. However, it falls short in terms of taking direct action based on these alerts. There are different methods of event capture, including through system labels and system calls, as well as via Kubernetes audit events. Notably, at the system level, Sysdig Secure can both detect and respond to events, allowing actions like blocking and warning. This proactive approach is effective at the system call level. However, when it comes to monitoring Kubernetes audit events, Sysdig Secure can only notify without being able to execute any further actions. It can't block access or containers. The vendor likened their role to that of a monitoring camera, observing events and sending notifications without the capacity to intervene. This limitation applies to Kubernetes audit events. Given that everything operates within our system, there is a workaround available: configuring system-level policies to block containers as necessary."

"Sysdig Secure needs to scale more for complete cloud-native coverage."

"Banks and financial institutions cannot use Sysdig Secure because it doesn't sell SaaS-hosted versions for under two hundred working nodes."

"Sysdig Secure works well for us, but there are a few areas for improvement, such as the alerting and notification system being more flexible for complex workflows, and some dashboard and reporting features could be more customizable to match specific team needs."

"Perhaps, it could support more custom implementations, as our company utilizes custom implementations rather than standard ones. Configuring it requires a deep understanding and adjustment to our specific needs, which took some time. Other than that, I'm unsure about potential improvements. We were considering the possibility of compartmentalizing their tools. Currently, in Sysdig Secure, they bundle multiple features, and we are unable to use them individually. For instance, if we only need compliance scanning, we have to deploy the entire secure package. This is because of the way their agent functions, but I can't delve into more details."

"I give it an eight because of the bugs, specifically the fix version bug where sometimes there is no fix version shown, and I wish Sysdig Secure would create a customizable UI that orders features by importance to enhance user experience."

More Sysdig Secure cons

"They could give a few more insights into security groups and recommendations on how to be more effective."

"I would like further support of Windows endpoint agents or the introduction of support for Windows endpoint agents."

"The user interface can be a little bit clunky at times... There's a lot of information that needs to be waded through, and the UI just isn't great."

"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."

"The compliance and governance need improvement."

"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 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."

"Some features do not work as expected."

Pricing and Cost Advice

"Qualys TotalCloud offers cost-effective licensing flexibility."

"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."

"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."

"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."

"The cost is high, but it meets our organizational needs."

"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."

"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."

"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."

More Qualys TotalCloud pricing and cost advice

"The solution's pricing depends on the agents...In short, the price depends on the environment of its user."

"I am always going to say that it could be a little bit cheaper. I do feel that it is a little bit on the expensive side."

"Sysdig is competitive. The quality matches the pricing. Obviously, everyone wants things to be cheaper, but if you're realistic, you acknowledge that quality service comes with a price. Sysdig is the gold standard for Kubernetes, and I wouldn't choose anything else. We live in Kubernetes. Everything is containerized, so that means a lot to us, and we're willing to make an investment."

"In comparison to other cloud solutions, it's reasonably priced. However, when compared to in-house built open-source projects, it might be considered somewhat costly. The cost depends on whether someone sees the support provided by Sysdig as an advantage or if it's deemed unnecessary. Personally, I find the support to be excellent and consider it a good value."

"It is quite costly compared to other tools."

"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."

"Pricing seems to be in line with the market structure. It's fine."

"It is a cost-effective choice versus other solutions on the market."

"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."

"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."

"It came in cheaper than Trend Micro when we purchased it a few years ago."
