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

"I highly recommend Qualys TotalCloud to other users."
"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."
"I would definitely recommend it because it is easy to handle any cloud resources."
"Its excellent graphical interface makes the scanning process simple."
"My main use case for Qualys TotalCloud is to find misconfiguration in the cloud, and I am focused on identifying misconfiguration in cloud configuration."
"The platform's unified view of the organization proves particularly valuable for leadership team meetings."
"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."
"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 scalability of the solution itself is unparalleled."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"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 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."
"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 features are the monitoring of users, endpoint detection and response, and the adaptability of the AI threat intelligence engine, which quickly adapts to customizations."
"The main feature is the security posture assessment through the security score. I find that to be very helpful because it gives us guidance on what needs to be secured and recommendations on how to secure the workloads that have been onboarded."
"This solution has the best security center, security manager dashboard that I have ever seen."
"DSPM is the most valuable feature."
"The technical support is very good."
"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."
"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."
"For any type of service, I would recommend the go-to solution for security on Azure is Security Center."
 

Cons

"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"To be honest, I would move out from this tool because it does not give a full view of vulnerability."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"There is room for improvement in the support."
"I chose a rating of nine out of ten because there is a complex interface that sometimes overwhelms new engineers."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"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."
"Their customer support needs improvement."
"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 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."
"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."
"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."
"The amount billed for the amount of terabytes you're scanning is too high and will lead into security risks if somebody is limiting the amount of data to be scanned based on the cost, so this is something I would prefer to be changed."
"One of the main challenges that we have been facing with Azure Security Center is the cost. The costs are really a complex calculation, e.g., to calculate the monthly costs. Azure is calculating on an hourly basis for use of the resource. Because of this, we found it really complex to promote what will be our costs for the next couple of months. I think if Azure could reduce the complex calculation and come up with straightforward cost mapping that would be very useful from a product point of view."
"Early on, the lack of transparency is a challenge. Microsoft does not tell you the cost when they launch something."
"Pricing could be improved. There are limited options based on pricing for the government."
"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."
"It's very expensive in terms of the need to maintain it actively."
"There should be an automated mechanism to design Azure policies based on the recommendations, possibly with AI integration. Instead of an engineer having to write a policy to fix security gaps, which is very time-consuming, there should be an inbuilt capability to auto-remediate everything and have proper control in place."
"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

"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"TotalCloud's price is about right where I would expect it to be."
"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."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"The cost is high, but it meets our organizational needs."
"Qualys TotalCloud is expensive."
"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."
"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."
"While we pay for any additional features, the pricing seems competitive, though I am not involved in the specific cost details."
"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."
"The licensing is straightforward but can become expensive if you cover everything. You must balance the cost against the importance of what needs covering."
"Defender's basic version is free, which is good. Many of our teams are evaluating the paid version against third-party products."
"The price of the solution is good for the features we receive and there is an additional cost for Microsoft premier support. However, some of my potential customers have found it to be expensive and have gone on to choose another solution."
"The cost is fair. There aren't any costs in addition to the standard licensing fee."
"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."
