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 insights streamline data security assessment
For Amazon Inspector, we have many EC2 or virtual machines deployed inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages. As we progress with time, this package needs to be updated for security enhancement, which requires us to uninstall the package, install the new version, and then we should be fine. However, the challenge comes with how to scan all our EC2 instances for security vulnerabilities, which is currently managed by Amazon Inspector. Amazon Inspector can scan EC2 instances or ECR, which is the ECR registry where we can save artifacts Docker images. Amazon Inspector can also scan Docker images uploaded to ECR for Elastic Registry service, and it can scan databases and S3 based on the latest updates. I noticed this from a couple of months ago, and it provides huge benefits for security. Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are causing security concerns. Amazon Inspector can list these security concerns and offer guidance on how we can remediate it by updating the package to a specific upper version or something similar.

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 helped us view our risk structure, vulnerabilities, and security posture."
"With TotalCloud, we can scan through the API. If we are not able to deploy cloud agents on the machine, we can use the API."
"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."
"The dashboards are particularly valuable as they offer a comprehensive view of the environment, highlighting any misconfigurations."
"If I had to say something positive about the product that brings me the biggest benefit, I would say it has accurate reports, gets new update CVEs, zero-day attack detection, and is easy to manage with its GUI."
"We were able to realize its benefits within 24 to 48 hours."
"TotalCloud's best feature is the integration of cloud accounts. It helps with the risk and security posture management of our cloud infrastructure."
"While automatic inventory detection upon connection is a helpful feature, a truly valuable capability would be assessing an environment's security posture against Azure and CIS best practices."
"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."
"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 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 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."
"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."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"The feature of Microsoft Defender for Cloud that I have found most valuable is the alerts, which are pretty standard for security."
"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."
"This is a platform as a service provided by Azure. We don't need to install or maintain Azure Security Center. It is a ready-made service available in Azure. This is one of the main things that we like. If you look at similar tools, we have to install, maintain, and update services. Whereas, Azure Security Center manages what we are using. This is a good feature that has helped us a lot."
"Microsoft Defender has a lot of features including regulatory compliance and attaching workbooks but the most valuable is the recommendations it provides for each and every resource when we open Microsoft Defender."
"Provides a very good view of the entire security setup of your organization."
"Microsoft Defender for Cloud is a valuable tool that integrates seamlessly with Azure Policy and our Security SIEM, simplifying implementation and enhancing security posture."
"There is no better tool found to protect workloads in Azure than Microsoft Defender for Cloud."
"DSPM is the most valuable feature."
 

Cons

"Qualys's ticketing system can be confusing when assigning tasks to individuals, and support could be improved by offering instant call solutions with engineers in addition to ticket replies."
"I would like the ability to disable certain default built-in policies as they can be misleading when creating dashboards. That is the top one."
"In my opinion, what can be improved in Qualys TotalCloud includes pricing and container scanning."
"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"The price is very expensive, actually."
"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"We would like to see Windows-based sensors available in Qualys, as this would make the platform more versatile and support a broader range of environments."
"With the growing integration of AI, I would like Qualys to enhance its service offerings to better accommodate AI-related risks."
"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."
"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."
"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."
"There are challenges associated with the interdependencies in AWS services, like requiring an Active Directory for other services, resulting in additional charges."
"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."
"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."
"The product's advanced analytics and reporting features could be improved."
"Integration into other third-party products, particularly those from tier three vendors like ManageEngine and Hexcode, has proven difficult."
"Azure Security Center should be more easily understood by a non-technical person. It needs to be simplified and made more user-friendly for a non-technical person."
"Microsoft sources most of their threat intelligence internally, but I think they should open themselves up to bodies that provide feel intelligence to build a better engine. There may be threats out there that they don't report because their team is not doing anything on that and they don't have arrangements with another party that is involved in that research."
"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."
"The solution is quite complex. A lot of the different policies that actually get applied don't pertain to every client. If you need to have something open for a client application to work, then you get dinged for having a port open or having an older version of TLS available."
"Microsoft Defender for Cloud is not compatible with Linux machines."
"There is a slight gap between the real-time monitoring and real-time alerts."
 

Pricing and Cost Advice

"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."
"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 is expensive, but it offers a premier solution with no headaches."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"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 offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"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."
"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."
"Azure Defender is a bit pricey. The price could be lower."
"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."
"Defender's basic version is free, which is good. Many of our teams are evaluating the paid version against third-party products."
"While we pay for any additional features, the pricing seems competitive, though I am not involved in the specific cost details."
"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 licensing cost per server is $15 per month."
"The licensing is straightforward but can become expensive if you cover everything. You must balance the cost against the importance of what needs covering."
"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."
