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

"Once it is set up, Qualys has proved to be one of our greatest assets."
"The most valuable feature of Qualys TotalCloud is the visibility it provides."
"Qualys TotalCloud is overall the best tool available in the market for scanning purposes."
"By integrating TotalCloud, we have significantly reduced vulnerabilities in our deployment pipeline."
"Qualys TotalCloud's most valuable feature is its ability to link clusters of assets, providing a clear model of deployments, vulnerabilities, and statuses."
"One of Qualys' best features is its categorization, which allows us to see the types of assets, their security postures, and the AI-powered version of the tool."
"Having everything in a single place to look for it and a single integration into ServiceNow has been the big transformation."
"In my opinion, this is the best tool."
"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."
"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"The automated vulnerability detection aspect is most valuable."
"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."
"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."
"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 most valuable feature of Amazon Inspector is the categorization of findings, which filters vulnerabilities by instance, container image, container repository, and Lambda function."
"No doubt it is useful as per the log analysis and threat protection analysis."
"For organizations who have an on-prem environment and are planning to move to a cloud-based solution, Azure Security Center is definitely one of the best tools that they can use."
"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."
"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."
"Having the ability to do what we could not before, such as gaining visibility and securing our full estate, is crucial."
"This solution is stable, it's 100% guaranteed and I've never had any problems with it other than some planned IT downtime."
"The most valuable features of this solution are the vulnerability assessments and the glossary of compliance."
"Microsoft Defender for Cloud can find potential phishing links and malicious code in data at rest."
 

Cons

"TotalCloud could improve its scanning of niche devices like Wi-Fi dongles and USB modems because they are often untested. It covers everything else, like laptops, mobile devices, and Bluetooth IoT devices. They can improve on the small IoT devices because hackers and testers use these."
"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."
"Qualys' customer service provides quality answers, but the response time is long, even though it is within the SLA."
"The cost of Qualys TotalCloud is high and could be more competitive."
"The vulnerability part is good, but the policy compliance module needs improvement because it involves a lot of manual work. Specifically, the remediation part of the controls requires enhancements."
"One thing that could be improved is the user experience and navigation."
"We encountered challenges identifying the correct resource category for certain items, such as those in containers or storage."
"I would appreciate additional integration options to connect Qualys TotalCloud with our other vulnerability management tools."
"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."
"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 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 is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."
"Microsoft Defender for Cloud is pricey, especially for Kubernetes clusters. It could be cheaper."
"As an analyst, there is no way to configure or create a playbook to automate the process of flagging suspicious domains."
"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."
"Microsoft has much room for improvement regarding the support for Microsoft Defender for Cloud. Their competitors are much better regarding support."
"There is no perfect product in the world and there are always features that can be added."
"However, some Copilot features aren't available in the GCP environment. This is something we hope will be addressed in the future."
"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."
"While we are satisfied with Defender for Cloud's features, an AI enhancement could potentially provide better advice and adapt more effectively to our environment."
 

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 is expensive."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"TotalCloud's price is about right where I would expect it to be."
"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."
"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."
"It's priced according to market standards for its services."
"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."
"There are improvements that have to be made to the licensing. Currently, for servers, it has to be done by grouping the servers on a single subscription... We don't have an option whereby, if all those resources are in one subscription, we can have each of the individual servers subject to different planning."
"The tool is pretty expensive."
"The licensing is straightforward but can become expensive if you cover everything. You must balance the cost against the importance of what needs covering."
"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."
"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."
"Pricing is a consideration, but we strive to keep costs low by enabling only necessary services."
"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."
"Currently, Microsoft offers only one plan at the enterprise level which is $15 per machine."
