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.

Automated vulnerability assessments continuously enhance security
The most valuable features probably are the ability to do automated vulnerability assessments, which it does with Amazon Inspector version two. It operates continuously, so as soon as resources are created, it scans them for vulnerabilities. This allows me to pinpoint potential security vulnerabilities and provide actionable recommendations relatively quickly. Larger enterprises usually use Inspector to gather all the vulnerabilities, the CVEs, across all accounts in an AWS organization. The enterprises I work for typically have many accounts in their organization, such as thousands of accounts where I am at the moment. It is a way to gather the vulnerabilities that are present on EC2 instances, container images, and Lambda functions.

Cloud security has cut investigation time and now reveals threats faster but needs simpler oversight
When deploying AI applications, my key security concerns with Microsoft Defender for Cloud are data loss, leakage of data, and guardrails around the actual AI, and I am hoping that this is going to help me put those guardrails in place and identify data exfiltration. Microsoft Defender for Cloud has not helped me manage and secure multi-cloud environments, as we are 100 percent Microsoft and have not really got it in any other environment at all. I am not yet using the unified AI-powered security feature offered by Microsoft Defender for Cloud, but that is coming. I am not yet using the integrated XDR feature of Microsoft Defender for Cloud, but that is coming. I am not yet utilizing the GenAI threat protection features of Microsoft Defender for Cloud. That is also coming and a lot of that will come from learning it here. I have enabled the agentless scanning in my cloud environment with Microsoft Defender for Cloud. Assessing the impact on my workload protection without needing to install agents with Microsoft Defender for Cloud makes it a lot easier, but it also identifies a lot more, which puts more load on me sometimes. I would advise another organization considering Microsoft Defender for Cloud that it is the most logical route to follow if their whole ecosystem is Microsoft. It is easy to implement and it is very self-explanatory when doing it, making sense to just follow the steps as it is too simple, really. I would rate this review a 7.5 out of 10.

Quotes from Members

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

Pros

"One of the most valuable features of Qualys TotalCloud is FlexScan, which is specifically for internet-facing VMs. We found this feature to be very useful. It was a key differentiator for us."
"I found the initial setup user-friendly."
"Qualys TotalCloud's most valuable feature is its ability to link clusters of assets, providing a clear model of deployments, vulnerabilities, and statuses."
"TruRisk Insights is the most important innovation they've released this year."
"I appreciate TotalCloud's real-time protection and remediation features. The remediation options include automated one-click remedies and custom changes that help manage vulnerabilities efficiently."
"I would recommend Qualys TotalCloud to other users because it is cost-efficient and has a good return on investment."
"By integrating TotalCloud, we have significantly reduced vulnerabilities in our deployment pipeline."
"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."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."
"The most valuable feature of Amazon Inspector is the categorization of findings, which filters vulnerabilities by instance, container image, container repository, and Lambda function."
"The integration of Amazon Inspector with other AWS services has enhanced our security. Security Hub is a major asset because it allows us to centralize data from various AWS services. We can integrate third-party tools as well. It is just a single-click option."
"The findings dashboards are neat and easy to understand, offering clear demarcations for different types of findings and detailed insights into specific vulnerabilities and their associated instances. It is not a place where everything is dumped together. It offers an easy-to-understand layout."
"The vulnerability discovery is valuable, and they also rank those vulnerabilities for you. So, you could rapidly attack some of the higher, severe vulnerabilities as they pop up, if they do pop up."
"The assessment reports provided by Amazon Inspector have helped me in identifying security vulnerabilities in my cloud applications by giving us a nicely designed dashboard that provides all the security information we need to work on remediation."
"The automated vulnerability detection aspect is most valuable."
"Most importantly, it's an integrated solution."
"The tool's most valuable feature is its support for cloud-native services like Kubernetes, containers, managed storage, and databases. Protecting these without Microsoft Defender for Cloud would be extremely challenging. For threat protection specifically, I find the signature-based detection and heuristic detection features very effective."
"When you have commissioned Defender, you have these things visible already on your dashboard. This gives the efficiency to the people to do their actual work rather than bothering about the email, sorting out the email, or looking at it through an ITSM solution, whey they have to look at the description and use cases. Efficiency increases with this optimized, ready-made solution since you don't need to invest in something externally. You can start using the dashboard and auditing capability provided from day one. Thus, you have fewer costs with a more optimized, easier-to-use solution, providing operational efficiency for your team."
"It alerts us to our vulnerabilities and ensures compliance by marking off a compliance tool checklist."
"Microsoft Defender for Cloud is a valuable tool that integrates seamlessly with Azure Policy and our Security SIEM, simplifying implementation and enhancing security posture."
"The most valuable features are the monitoring of users, endpoint detection and response, and the adaptability of the AI threat intelligence engine, which quickly adapts to customizations."
"The solution is used for risks, vulnerabilities, and compliance."
"Defender is a robust platform for dealing with many kinds of threats; we're protected from various threats, like viruses, and attacks can be easily minimized with this solution defending our infrastructure."
 

Cons

"The improvement needed in Qualys TotalCloud is mainly in the artificial intelligence automation agents, where we can customize and create what meets our needs, not necessarily having to use those provided in the tool."
"Enhancing clarity regarding its compliance capabilities would be beneficial, as the current scope is limited in geographic coverage."
"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"The price is very expensive, actually."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"In my opinion, what can be improved in Qualys TotalCloud includes pricing and container scanning."
"To be honest, I would move out from this tool because it does not give a full view of vulnerability."
"The other point is that the reporting features of Inspector need improvement. For example, I am in an organization with millions of CVEs, and getting an overview of all this is challenging."
"It has a limited scope. So, AWS Inspector primarily focuses on the security of the EC2 instance. So, if your architecture includes other AWS services, then you may need to use additional tools for your comprehensive security assessment. So that is one con. Another is, like, we have a dependency on agents."
"There are challenges associated with the interdependencies in AWS services, like requiring an Active Directory for other services, resulting in additional charges."
"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."
"One area for improvement in Amazon Inspector is the automation aspect."
"One major area for improvement is remediation. My team works on remediating findings over time, likely using available patches. However, easier integration with Amazon's patching services would be very helpful."
"The false positive rate of Amazon Inspector is a little high, and it is not covering all different applications and scanning."
"There isn't too much to improve right now. Scanning on demand or as a part of the pipeline versus a post pipeline solution would be good, but it is not a deal breaker by any means."
"The most significant areas for improvement are in the security of our identity and endpoints and the posture of the cloud environment. Better protection for our cloud users and cloud apps is always welcome."
"The amount billed for the amount of terabytes you're scanning is too high and will lead into security risks if somebody is limiting the amount of data to be scanned based on the cost, so this is something I would prefer to be changed."
"An area where Microsoft Defender for Cloud could be improved is in getting away from having multiple menus that do the same thing, which seems imposing when looking at it."
"I would suggest building a single product that addresses endpoint server protection, attack surface, and everything else in one solution. That is the main disadvantage with the product. If we are incorporating some features, we end up in a situation where this solution is for the server, and that one is for the client, or this is for identity, and that is for our application. They're not bundling it. Commercially, we can charge for different licenses, but on the implementation side, it's tough to help our end-customer understand which product they're getting."
"After getting a recommendation, it takes time for the solution to refresh properly to show that the problem has been eliminated."
"Defender could provide more in-depth visibility into vulnerabilities and services. For instance, we wanted to scan Azure NetApp for sensitive data, but they didn't have that feature. It was only for storage accounts. I want Azure Defender features to cover all Azure resources rather than a few."
"I would rate Microsoft Defender for Cloud a six out of 10 due to its lack of necessary features to operate as a standalone solution."
"Most customer teams need more training on this type of product."
 

Pricing and Cost Advice

"Qualys TotalCloud is expensive."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"I am not sure about the pricing. From what I understand, it is a bit on the higher side, but I do not have the exact numbers."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"Although Qualys TotalCloud is relatively expensive due to its unique automation features, its cost-effectiveness is rated an eight out of ten, with ten being the most costly."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"The cost is high, but it meets our organizational needs."
"It is scaled as you go. There are probably a certain number of scans per month, and there are tiers. If you're under a certain tier, it is free. The second level is pennies, and then all the way up to like a million. So, it has a tiered pricing program. They're pretty good with your initial scanning, and there is room to scale based on being affordable, but it is fairly cheap. There are no additional costs. They pretty much think about it as a pay-per-scan type model."
"The lowest cost would be around $10 for a few small accounts, however, for thousands of accounts, it could be around $5000 to $6000 dollars per month."
"The pricing is very transparent and clear."
"It's priced according to market standards for its services."
"The solution is expensive, and I rate it a five to six out of ten."
"It is bundled with our enterprise subscription, which makes it easy to go for it. It is available by default, and there is no extra cost for using the standard features."
"Defender for Cloud is pretty costly for a single line. It's incredibly high to pay monthly for security per server. The cost is considerable for an enterprise with 500-plus virtual machines, and the monthly bill can spike."
"Microsoft's licensing and pricing are sometimes complicated. If someone is new to Microsoft's licensing, they might have difficulty with it."
"Defender's basic version is free, which is good. Many of our teams are evaluating the paid version against third-party products."
"I'm not privy to that information, but I know it's probably close to a million dollars a year."
"We are using the free version of the Azure Security Center."
"There are two different plans. We're using the secure basic plan, but we have used the end security plan as well. There are additional costs, but it gives us more functionalities compared to the basic plan."
