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 has improved our security posture."
"The agent and agentless scanning in TotalCloud, particularly the FlexScan method, is incredibly valuable. With traditional scanning approaches, we had to give IP ranges and whitelist IPs. All that is now simplified. FlexScan requires minimal intervention, and after configuration, it automatically collects data and performs necessary scans."
"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."
"Qualys TotalCloud has significantly reduced our workload in terms of managing risks, helping us to be more efficient and save substantial resources."
"Once you have your vulnerabilities fixed and your patches pushed out using Qualys TotalCloud, then you are able to eliminate threats and cyber risk."
"Qualys TotalCloud has saved our time by giving us better asset visibility and risk-based prioritization, as it has reduced the time spent manually reviewing CVEs and deciding what to address first."
"We were able to realize its benefits within 24 to 48 hours."
"The scalability is good as well. I would rate it ten out of ten."
"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."
"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."
"The scalability of the solution itself is unparalleled."
"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."
"It is scanning the whole repository for any sort of vulnerabilities, so it allows us to be more confident in our DevSecOps and not put a lot of folks or attention to it."
"The automated vulnerability detection aspect is most valuable."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"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."
"Some of the most valuable features of Microsoft Defender for Cloud include its effectiveness in threat detection through unsupervised machine learning, CTI, and advanced sandboxing."
"The main feature is the security posture assessment through the security score. I find that to be very helpful because it gives us guidance on what needs to be secured and recommendations on how to secure the workloads that have been onboarded."
"The most valuable features of this solution are the remote workforce capabilities and the general experience of the remote workforce."
"It has improved our security posture a lot, and with the implementation of Azure Security Center, we have resolved many issues, including being able to do security monitoring of the complete infrastructure across both cloud and on-prem environments."
"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."
"Our primary use case of this solution is to monitor infrastructure."
"It helps you to identify the gaps in your solution and remediate them, and it produces a compliance checklist against known standards such as ISO 27001, HIPAA, iTrust, etc."
"The solution helped out management a lot, reducing about 50% of the time needed to spend on this after implementation and saving the organization money by consolidating into one solution instead of two or three."
 

Cons

"Customer support with Qualys TotalCloud needs a little improvement with the response times."
"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"The response part of the Cloud Detection and Response (CDR) module can be improved."
"One thing that could be improved is the user experience and navigation."
"Their support could be improved."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"In TotalCloud, I would suggest improvements in policy checks to cater to various inventory types like VPCs, subnets, S3 buckets, or IAMs. There is a lack of data segregation according to criticality or inventory."
"In a future release, I suggest that zero-day vulnerabilities should be predicted in advance using AI technologies. The system is not 100% secure yet, so proactive threat hunting could be enhanced to be more proactive than the current system."
"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."
"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."
"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."
"One area for improvement in Amazon Inspector is the automation aspect."
"There are challenges associated with the interdependencies in AWS services, like requiring an Active Directory for other services, resulting in additional charges."
"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."
"The false positive rate of Amazon Inspector is a little high, and it is not covering all different applications and scanning."
"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."
"There is no perfect product in the world and there are always features that can be added."
"I've heard there might be issues with scalability for larger enterprises."
"The solution could improve by being more intuitive and easier to use requiring less technical knowledge."
"Customer service and support from Microsoft are very poor. Even for high-severity cases, response or resolution time can extend to three or four weeks."
"The solution's portal is very easy to use, but there's one key component that is missing when it comes to managing policies. For example, if I've onboarded my server and I need to specify antivirus policies, there's no option to do that on the portal. I will have to go to Intune to deploy them. That is one main aspect that is missing and it's worrisome."
"Although Microsoft Defender for Cloud is based on security, I wish it went beyond providing assessments, reports, and generic steps. More detailed procedures would be helpful, especially for lower-level support staff."
"Azure is a complex solution. You have so many moving parts."
"For Kubernetes, I was using Azure Kubernetes Service (AKS). To see that whatever is getting deployed into AKS goes through the correct checks and balances in terms of affinities and other similar aspects and follows all the policies, we had to use a product called Stackrox. At a granular level, the built-in policies were good for Kubernetes, but to protect our containers from a coding point of view, we had to use a few other products. For example, from a programming point of view, we were using Checkmarx for static code analysis. For CIS compliance, there are no CIS benchmarks for AKS. So, we had to use other plugins to see that the CIS benchmarks are compliant. There are CIS benchmarks for Kubernetes on AWS and GCP, but there are no CIS benchmarks for AKS. So, Azure Security Center fell short from the regulatory compliance point of view, and we had to use one more product. We ended up with two different dashboards. We had Azure Security Center, and we had Stackrox that had its own dashboard. The operations team and the security team had to look at two dashboards, and they couldn't get an integrated piece. That's a drawback of Azure Security Center. Azure Security Center should provide APIs so that we can integrate its dashboard within other enterprise dashboards, such as the PowerBI dashboard. We couldn't get through these aspects, and we ended up giving Reader security permission to too many people, which was okay to some extent, but when we had to administer the users for the Stackrox portal and Azure Security Center, it became painful."
 

Pricing and Cost Advice

"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"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."
"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 cost-efficient and was selected for its value compared to other products."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"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."
"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."
"Its pricing is a little bit high in terms of Azure Security Center, but the good thing is that we don't need to maintain and deploy it. So, while the pricing is high, it is native to Azure which is why we prefer using this tool."
"The price of the solution is good for the features we receive and there is an additional cost for Microsoft premier support. However, some of my potential customers have found it to be expensive and have gone on to choose another solution."
"The cost of the license is based on the subscriptions that you have."
"This is a worldwide service and depending on the country, there will be different prices."
"This solution is more cost-effective than some competing products. My understanding is that it is based on the number of integrations that you have, so if you have fewer subscriptions then you pay less for the service."
"The pricing and licensing of Microsoft Defender for Cloud have been good for us. We appreciate the licensing approach based on employee count rather than a big enterprise license."
