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 bank's performance, and we have definitely seen benefits after implementing this solution."
"In my opinion, this is the best tool."
"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."
"My experience with using TruRisk to mitigate noise from raw CVEs has been extremely effective."
"We were able to realize its benefits within 24 to 48 hours."
"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."
"Its excellent graphical interface makes the scanning process simple."
"I rate the breadth of FlexScan in providing visibility into on-premises, multicloud, and container environments as fantastic."
"The scalability of the solution itself is unparalleled."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"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 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 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."
"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 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."
"I find Microsoft Defender for Cloud's KQL very flexible and powerful. It's really easy to search through with KQL queries to find the security breaches and incidents and to track down the breach itself."
"Microsoft Defender for Cloud has definitely helped us manage and secure our multi-cloud environment by providing ease of use."
"I would rate Microsoft Defender for Cloud a ten."
"Defender lets you orchestrate the roll-out from a single pane. Using the Azure portal, you can roll it out over all the servers covered by the entire subscription."
"Defender for Cloud provides a complete DevOps security package for cloud services."
"The scalability of Microsoft Defender for Cloud is very good."
"Defender for Cloud has improved our security posture."
"Microsoft Defender for Cloud monitors our entire cloud environment. It enables conditional access and incorporates features like number matching and single sign-on for all our cloud apps. It is great for protecting against ransomware and various security threats."
 

Cons

"Although TotalCloud is a helpful tool, some of its advanced features are still under development."
"The price is very expensive, actually."
"Qualys TotalCloud's increasing complexity, due to the development and deployment of multiple solutions, is making the GUI difficult to navigate."
"The cloud licensing unit system is unclear, especially since "units" aren't well-defined."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"Two areas for improvement in Qualys TotalCloud are the speed of the public cloud platform and vulnerability detection."
"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"Regarding technical support from Qualys, they respond, but the response time can be too long. Sometimes we need to wait weeks for solutions to simple questions."
"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."
"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."
"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 area for improvement in Amazon Inspector is the automation aspect."
"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."
"The initial setup is not actually so complex but it feels complex because there are many add-ons. There are many options and my team needs to be aware of all of these changes happening on the backend which is a distraction."
"No possibility to write or edit any capability."
"The cost is always a concern, but overall, it's not too bad because it is easy to use and pretty friendly."
"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."
"Defender is occasionally unreliable. It isn't 100% efficient in terms of antivirus detection, but it isn't an issue most of the time. It's also somewhat difficult to train new security analysts to use Defender."
"Azure is a complex solution. You have so many moving parts."
"Features like code scanning and pipeline scanning are not included in the solution."
 

Pricing and Cost Advice

"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"Qualys TotalCloud offers cost-effective licensing flexibility."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"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."
"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."
"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."
"The pricing is very transparent and clear."
"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."
"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."
"I'm not privy to that information, but I know it's probably close to a million dollars a year."
"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."
"Pricing depends on your workload size, but it is very cheap. If you're talking about virtual machines, it is $5 or something for each machine, which is minimal. If you go for some agent-based solution for every virtual machine, then you need to pay the same thing or more than that. For an on-premises solution like this, we were paying around $30 to $50 based on size. With Defender, Microsoft doesn't bother about the size. You pay based on the number of machines. So, if you have 10 virtual machines, and 10 virtual machines are being monitored, you are paying based on that rather than the size of the virtual machine. Thus, you are paying for the number of units rather than paying for the size of your units."
"The licensing is straightforward but can become expensive if you cover everything. You must balance the cost against the importance of what needs covering."
"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."
"This is a worldwide service and depending on the country, there will be different prices."
"We only use the free tier, so we haven't faced any pricing, setup costs, or licensing challenges."
