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 positively impacted our organization by helping us save time and manage all assets and remediation, allowing us to achieve quarterly and half-yearly goals."
"I rate the breadth of FlexScan in providing visibility into on-premises, multicloud, and container environments as fantastic."
"The most valuable feature is extensibility."
"By integrating TotalCloud, we have significantly reduced vulnerabilities in our deployment pipeline."
"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."
"Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution."
"The most valuable feature is the consolidated information that it provides from various platforms."
"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."
"The automated vulnerability detection aspect is most valuable."
"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."
"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."
"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 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."
"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."
"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."
"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."
"Defender for Cloud provides a prioritized list of remediations for security issues, reducing risk and improving security operations."
"Good compliance policies."
"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."
"Microsoft Defender for Cloud has benefited my organization by reducing the overall cost of the Azure package and providing greater peace of mind during off-hours to prevent problems."
"One of the features that I like about the solution is it is both a hybrid cloud and also multi-cloud. We never know what company we're going to buy, and therefore we are ready to go. If they have GCP or AWS, we have support for that as well. It offers a single-panel blast across multiple clouds."
"The most valuable features of the solution are the insights, meaning the remediation suggestions, as well as the incident alerts."
"Provides a very good view of the entire security setup of your organization."
 

Cons

"Qualys TotalCloud has the potential to improve by integrating a hybrid platform for comprehensive management of both on-premises and cloud infrastructures."
"The cloud licensing unit system is unclear, especially since "units" aren't well-defined."
"Qualys TotalCloud's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."
"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."
"The patching process with Qualys Patch Management, which is part of TotalCloud, does not cover installing certain prerequisites on the servers or workstations. This shortcoming means we must rely on SCCM when any service stack updates or additional prerequisites are needed."
"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."
"In my opinion, the combination of detection and protection features in Qualys TotalCloud cannot protect but can only detect."
"Qualys TotalCloud can be improved in the integration piece, especially with ServiceNow, where there's a bidirectional sync integrated, as there is no native capability from Qualys that can give monitoring metrics of how many assets came in and how many failed or were not properly reconciled or combined."
"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."
"The most challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."
"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."
"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."
"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."
"There are challenges associated with the interdependencies in AWS services, like requiring an Active Directory for other services, resulting in additional charges."
"There is a slight gap between the real-time monitoring and real-time alerts."
"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."
"The pricing is very difficult because every type of Defender for Cloud has its own metrics and pricing."
"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."
"While we are satisfied with Defender for Cloud's features, an AI enhancement could potentially provide better advice and adapt more effectively to our environment."
"There are many unknowns with AI applications. AI agents will operate while you're not present, whether you are sleeping or awake, and it's unclear whether there would be any exfiltration of data or how data is being managed."
"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."
"The solution could extend its capabilities to other cloud providers. Right now, if you want to monitor a virtual machine on another cloud, you can do that. However, this cannot be done with other cloud platform services. I hope once that is available then Defender for Cloud will be a unified solution for all cloud platform services."
 

Pricing and Cost Advice

"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"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."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"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."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"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."
"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."
"Currently, Microsoft offers only one plan at the enterprise level which is $15 per machine."
"Understanding the costs of cloud services can be complicated at first. As with a lot of things in the cloud, it can be quite hard to understand the end cost, but it becomes clearer over time. Early on, the lack of transparency is a challenge. Microsoft does not tell you the cost when they launch something. It is clever marketing, and there is room for improvement there. There should be clarity from the start."
"Azure Defender is a bit pricey. The price could be lower."
"It has global licensing. It comes with multiple licenses since there are around 50,000 people (in our organization) who look at it."
"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."
"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."
"I am not involved in this area. However, I believe its price is okay because even small customers are using Azure Security Center. I don't think it is very expensive."
"Microsoft Defender for Cloud is pricey, especially for Kubernetes clusters."
