Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

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inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages.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 Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are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's most valuable features are its security capabilities that help identify and mitigate risk factors."
"The most valuable feature of Qualys TotalCloud is the visibility it provides."
"I appreciate TotalCloud's real-time protection and remediation features. The remediation options include automated one-click remedies and custom changes that help manage vulnerabilities efficiently."
"If someone were to ask me to review Qualys TotalCloud, I would summarize it as an end-to-end solution for cloud security with visibility and governance-grade controls without needing to manage multiple disconnected tools."
"Once you have your vulnerabilities fixed and your patches pushed out using Qualys TotalCloud, then you are able to eliminate threats and cyber risk."
"We were able to realize its benefits within 24 to 48 hours."
"One of the features I appreciate is the ability to generate daily reports without relying on anyone else."
"TruRisk Insights is the most important innovation they've released this year."
"The most valuable feature of Amazon Inspector is the categorization of findings, which filters vulnerabilities by instance, container image, container repository, and Lambda function."
"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."
"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."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"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 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 operates continuously, so as soon as resources are created, it scans them for vulnerabilities."
"The scalability of the solution itself is unparalleled."
"I have not experienced any difficulties or issues with the stability of Microsoft Defender for Cloud."
"Threat protection is comprehensive and simple."
"Everything is built into Azure, and if we go for cross-cloud development with Azure Arc, we can use most of the features. While it's possible to deploy and convert third-party applications, it is difficult to maintain, whereas Azure deployments to the cloud are always easier. Also, Microsoft is a big company, so they always provide enough support, and we trust the Microsoft brand."
"Threat protection is comprehensive and simple."
"The solution is up-to-date with the latest updates and identified threats."
"It's quite a good product. It helps to understand the infections and issues you are facing."
"The integration with Logic Apps allows for automated responses to incidents."
"Using Security Center, you have a full view, at any given time, of what's deployed, and that is something that is very useful."
 

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."
"TotalCloud could improve the classification of vulnerabilities. Specifically, it could enhance the categorization of what aspects fall under patches resolved by OS or software updates and what pertains to configuration adjustments."
"With the growing integration of AI, I would like Qualys to enhance its service offerings to better accommodate AI-related risks."
"Qualys TotalCloud needs to improve its accuracy for non-Windows operating systems."
"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."
"Some major banks and insurance companies require an on-premises solution for comprehensive vulnerability management, which TotalCloud does not offer."
"To improve the user experience, reporting could be simplified for better comprehension by end users and project managers, facilitating issue resolution."
"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"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."
"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."
"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."
"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."
"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 false positive rate of Amazon Inspector is a little high, and it is not covering all different applications and scanning."
"Sometimes it's very difficult to determine when I need Microsoft Defender for Cloud for a special resource group or a special kind of product."
"The pricing could be improved, as it is somewhat high for smaller companies."
"The solution is quite complex. A lot of the different policies that actually get applied don't pertain to every client."
"The range of workloads is broad, but we'd love to add more workloads and make it a single security solution that covers all those workloads. Covering more would allow us to see and protect more workloads from a single pane of glass. Additional features should include protection for more AI workloads as it currently focuses primarily on OpenAI."
"I would like to see more connectors and plugins with other platforms."
"The pricing could be improved, as it is somewhat high for smaller companies."
"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."
"Most of the time, when we log into the support, we don't get a chance to interact with Microsoft employees directly, except having it go to outsource employees of Microsoft. The initial interaction has not been that great because outsourced companies cannot provide the kind of quality or technical expertise that we look for. We have a technical manager from Microsoft, but they are kind of average unless we make noise and ask them to escalate. We then can get the right people and the right solution, but it definitely takes time."
 

Pricing and Cost Advice

"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"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 offers cost-effective licensing flexibility."
"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"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."
"Qualys TotalCloud offers good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."
"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 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."
"The pricing is very transparent and clear."
"Our clients complain about the cost of Microsoft Defender for Cloud."
"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 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."
"The solution is expensive, and I rate it a five to six out of ten."
"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."
"We are using the free version of the Azure Security Center."
"The pricing model for most plans is generally good, but the cost of the new Defender for Storage plan is high and should be revisited, as it could lead to disabling desirable security features due to cost."
