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.

Principal Security Architect at Nagarro
Has supported cloud-specific threat scanning but lacks coverage across hybrid and third-party workloads
They might launch support for third-party environments in the next version regarding the best features in Amazon Inspector from my perspective. The false positive rate of Amazon Inspector is a little high, and it is not covering all different applications and scanning. It mostly covers specific native applications, and I think as per my understanding, it doesn't cover third-party environments or hybrid environments.

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 fulfills all these needs."
"Once it is set up, Qualys has proved to be one of our greatest assets."
"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."
"I like the web API security and IoT scanning features the most. The user-friendly design of TotalCloud's interface enables customers to navigate it and use its full potential easily"
"The most valuable feature is extensibility."
"Qualys TotalCloud provides unified vulnerability and threat assessment for IaaS and SaaS and a single prioritized view of risk, which helps reduce my workload by not having to combine multiple sources."
"Qualys TotalCloud's most valuable feature is its ability to link clusters of assets, providing a clear model of deployments, vulnerabilities, and statuses."
"Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"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."
"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 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 scalability of the solution itself is unparalleled."
"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 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."
"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 solution's coordinated detection and response across devices and identities is impressive because it is complete."
"If you're in the world of cloud and your company is using Azure as their primary cloud, I think Azure Security Center is a must-have feature, because it provides a bird's eye view of the entire security position of the organization."
"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."
"When we started out, our secure score was pretty low, we adopted some of the recommendations that Security Center set out and we were able to make good progress on improving it, as it had been in the low thirties and is now in the upper eighties."
"Microsoft Defender for Cloud has improved our security poster by at least 100 percent."
"The dashboard is very good; it gives our clients a lot of information and allows them to have a complete overview of the system, with everything visible in one glance."
"The most valuable feature for me is the variety of APIs available."
 

Cons

"I think Qualys TotalCloud needs to improve its handling of zero-day vulnerabilities and supply chain management because modern ransomware attacks not only target prime critical infrastructures but also the supply chain system."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"The downside is only in container security, but it has not been a long time since they introduced these models."
"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."
"Regarding improvements to Qualys TotalCloud, I suggest that user navigation can be enhanced because initially, many users found it complicated and had trouble understanding the platform due to information being spread across multiple tabs."
"It has been working very well, but it would be helpful if the dashboard could generate reports tailored to specific compliance needs. For example, in India, we have to comply with RBI and SEBI guidelines. It w"
"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."
"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."
"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 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."
"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."
"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."
"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."
"The documentation could be much clearer."
"Another thing is that Defender for Cloud uses more resources than for instance, CrowdStrike, which my current company uses."
"I would like to have the ability to customize executive reporting."
"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."
"Consistency is the area where the most improvement is needed. For example, there are some areas where the UI is not uniform across the board."
"The pricing is very difficult because every type of Defender for Cloud has its own metrics and pricing."
"I've heard there might be issues with scalability for larger enterprises."
 

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 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."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"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."
"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."
"TotalCloud's price is about right where I would expect it to be."
"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."
"We are using the free version of the Azure Security Center."
"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."
"Pricing is difficult because each license has its own metrics and cost."
"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."
"It has global licensing. It comes with multiple licenses since there are around 50,000 people (in our organization) who look at it."
"The licensing is straightforward but can become expensive if you cover everything. You must balance the cost against the importance of what needs covering."
"Our clients complain about the cost of Microsoft Defender for Cloud."
"Microsoft's licensing and pricing are sometimes complicated. If someone is new to Microsoft's licensing, they might have difficulty with it."
