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

"Having everything in a single place to look for it and a single integration into ServiceNow has been the big transformation."
"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."
"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 rate the breadth of FlexScan in providing visibility into on-premises, multicloud, and container environments as fantastic."
"The scalability is good as well. I would rate it ten out of ten."
"Generally, Qualys is very good at detections, whether on cloud or on-prem, and the agent allows deployment on both infrastructures, providing continuous monitoring of your assets, which is a key selling point for us."
"Qualys TotalCloud fulfills all these needs."
"The best feature would be the ability to create policies. It is easy to control and update policies as required."
"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."
"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."
"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."
"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 automated vulnerability detection aspect is most valuable."
"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 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 most valuable feature for me is the variety of APIs available."
"The technical support is very good."
"The valuable features include the ability to manage devices and the fact that Defender can replace other security tools like SCCM."
"It isn't a highly complex solution. It's something that a lot of analysts can use. Defender gives you a broad overview of what's happening in your environment, and it's a great solution if you're a Microsoft shop."
"Microsoft Defender for Cloud helps in improving our overall security posture. We have a nice overview of what is missing where and what can be improved."
"The entire Defender Suite is tightly coupled, integrated, and collaborative."
"It is very scalable, the product has been very easy to use and simple to set up, the maintenance and updating are part of the service so that brings great value, it's a stable product, technical support is helpful, and it's got a lot of great features."
"The solution has also simplified management of endpoints and servers and gives us visibility in a single pane of glass."
 

Cons

"The cloud licensing unit system is unclear, especially since "units" aren't well-defined."
"In terms of improvement, remediation still belongs to the cloud team, which is one of the issues we faced with Qualys TotalCloud."
"I would appreciate additional integration options to connect Qualys TotalCloud with our other vulnerability management tools."
"There is a lack of data segregation according to criticality or inventory."
"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"The response part of the Cloud Detection and Response (CDR) module can be improved."
"The onboarding process is a bit difficult. In the initial phase, it is very difficult to understand the features, what the dashboard contains, and what criteria they are using."
"To be honest, I would move out from this tool because it does not give a full view of vulnerability."
"The false positive rate of Amazon Inspector is a little high, and it is not covering all different applications and scanning."
"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."
"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 challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."
"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."
"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."
"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."
"I don't know what the issue is but when we do the agent deployment, sometimes it works, and sometimes it fails and we need to go inside the virtual machine and manually install the agent."
"Azure Security Center takes a long time to update, compared to the on-premises version of Microsoft Defender."
"There is no perfect product in the world and there are always features that can be added."
"Agent features need to be improved. They support agents through Azure Arc or Workbench. Sometimes, we are not able to get correct signals from the machines on which we have installed these agents. We are not able to see how many are currently reporting to Azure Security Center, and how many are currently not reporting. For example, we have 1,000 machines, and we have enrolled 1,000 OMS agents on these machines to collect the log. When I look at the status, even though at some places, it shows that it is connected, but when I actually go and check, I'm not getting any alerts from those. There are some discrepancies on the agent, and the agent features are not up to the mark."
"Another thing that could be improved was that they could recommend processes on how to react to alerts, or recommend best practices based on how other organizations do things if they receive an alert about XYZ."
"Microsoft Defender for Cloud is not compatible with Linux machines."
"If a customer is already using Okta as an SSO in its entire environment, they will want to continue with it. But Security Center doesn't understand that and keeps making recommendations. It would help if it let us resolve a recommendation, even if it is not implemented."
"I felt that there was disconnection in terms of understanding the UI. The communication for moving from the old UI to the new UI could be improved. It was a bit awkward."
 

Pricing and Cost Advice

"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 offers cost-effective licensing flexibility."
"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."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"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 cost is high, but it meets our organizational needs."
"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
"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."
"The pricing is very transparent and clear."
"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."
"I am not involved much with the pricing but the bundle offering is good."
"Defender's basic version is free, which is good. Many of our teams are evaluating the paid version against third-party products."
"Azure Defender is definitely pricey, but their competitors cost about the same. For example, a Palo Alto solution is the same price per endpoint, but the ground strikes cost a bit more than Azure Defender. Still, it's pricey for a company like ours. Maybe well-established organizations can afford it, but it might be too costly for a startup."
"This is a worldwide service and depending on the country, there will be different prices."
"Azure Defender is a bit pricey. The price could be lower."
"The licensing cost per server is $15 per month."
"While we pay for any additional features, the pricing seems competitive, though I am not involved in the specific cost details."
"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."
