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

"Qualys TotalCloud is overall the best tool available in the market for scanning purposes."
"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."
"I would definitely recommend it because it is easy to handle any cloud resources."
"The dashboards are particularly valuable as they offer a comprehensive view of the environment, highlighting any misconfigurations."
"Qualys TotalCloud provides a single, prioritized view based on requirements such as identifying the most vulnerable assets and calculating the average time to remediate vulnerabilities."
"I appreciate Qualys TotalCloud's ability to onboard any type of device with ease, including containers."
"Multi-cloud visibility saves time and makes things easier, as we can also have comparability to see what configuration differences have been made from cloud to cloud."
"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."
"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 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 most valuable feature of Amazon Inspector is the categorization of findings, which filters vulnerabilities by instance, container image, container repository, and Lambda function."
"My experience with AWS technical support is very good, I didn't face any specific challenges, and even the documentation of AWS is good for both Microsoft, which is Azure, and AWS."
"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 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."
"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"We are using this solution to implement our CAS policy and it monitors compliance with the Security Center, and we also use it for threat protection as it detects any threats and provides threat recommendations."
"The most valuable feature for me is the variety of APIs available."
"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 solution is up-to-date with the latest updates and identified threats."
"From a security perspective, it reduced the amount of risk for employees, contractors, and users who might try to go to dangerous sites, as we blocked them."
"It alerts us to our vulnerabilities and ensures compliance by marking off a compliance tool checklist."
"The most valuable feature is the recommendations provided on how to improve security. It has made the cloud environment more secure, thanks to all the recommendations we can get."
"The scalability of Microsoft Defender for Cloud is very good."
 

Cons

"One thing that could be improved is the user experience and navigation."
"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"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's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."
"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."
"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."
"Their customer support needs improvement."
"There should be improvement from a dashboard perspective when collecting and showcasing data to lead management."
"One area for improvement in Amazon Inspector is the automation aspect."
"The false positive rate of Amazon Inspector is a little high, and it is not covering all different applications and scanning."
"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."
"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 most challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."
"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."
"There are challenges associated with the interdependencies in AWS services, like requiring an Active Directory for other services, resulting in additional charges."
"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 solution is quite complex. A lot of the different policies that actually get applied don't pertain to every client. If you need to have something open for a client application to work, then you get dinged for having a port open or having an older version of TLS available."
"I rate Microsoft support five out of 10. It gets better once you're escalated past the first and second levels. It's difficult to get the necessary support when tickets are first opened."
"As an analyst, there is no way to configure or create a playbook to automate the process of flagging suspicious domains."
"Customizing some of the compliance requirements based on individual needs seems like the biggest area of improvement. There should be an option to turn specific controls on and off based on how your solution is configured."
"Microsoft Defender for Cloud can be improved because many of the functions involve multiple places to accomplish the same task, which can make it convoluted."
"There are challenges with the licensing policies, which are quite complicated."
"The remediation process could be improved."
"There should be an automated mechanism to design Azure policies based on the recommendations, possibly with AI integration. Instead of an engineer having to write a policy to fix security gaps, which is very time-consuming, there should be an inbuilt capability to auto-remediate everything and have proper control in place."
 

Pricing and Cost Advice

"The cost is high, but it meets our organizational needs."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"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."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"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 expensive, but it offers a premier solution with no headaches."
"TotalCloud's price is about right where I would expect it to be."
"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."
"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 pricing is very transparent and clear."
"It's priced according to market standards for its services."
"Although I am outside of the discussion on budget and costing, I can say that the importance of security provided by this solution is of such importance that whatever the cost is, it is not a factor."
"Defender's basic version is free, which is good. Many of our teams are evaluating the paid version against third-party products."
"The licensing cost per server is $15 per month."
"The pricing is very difficult because every type of Defender for Cloud has its own metrics and pricing. If you have Cloud for Key Vault, the pricing is different than it is for storage. Every type has its own pricing list and rules."
"Security Center charges $15 per resource for any workload that you onboard into it. They charge per VM or per data-base server or per application. It's not like Microsoft 365 licensing, where there are levels like E3 and E5. Security Center is pretty straightforward."
"Pricing is a consideration, but we strive to keep costs low by enabling only necessary services."
"It has global licensing. It comes with multiple licenses since there are around 50,000 people (in our organization) who look at it."
"Our clients complain about the cost of Microsoft Defender for Cloud."
