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inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages.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 Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are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 has improved our security posture."
"TotalCloud provides the easiest and the best approach for cloud infrastructure management."
"Qualys TotalCloud helps you not just to identify misconfigurations, but you can actually also fix issues."
"Vulnerability and threat detection and assessment of the criticality of the vulnerabilities exposed are most valuable."
"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."
"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."
"Qualys TotalCloud's most valuable feature is its agent versatility."
"Qualys TotalCloud has significantly reduced our workload in terms of managing risks, helping us to be more efficient and save substantial resources."
"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 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."
"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."
"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 automated vulnerability detection aspect is most valuable."
"The scalability of the solution itself is unparalleled."
"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."
"There is no better tool found to protect workloads in Azure than Microsoft Defender for Cloud."
"The feature of Microsoft Defender for Cloud that I have found most valuable is the alerts, which are pretty standard for security."
"Good compliance policies."
"The most valuable features offer the latest threat detection and response capabilities."
"Microsoft Defender for Cloud has made our environment more secure."
"The solution is up-to-date with the latest updates and identified threats."
"The solution helped out management a lot, reducing about 50% of the time needed to spend on this after implementation and saving the organization money by consolidating into one solution instead of two or three."
 

Cons

"The patching process with Qualys Patch Management, which is part of TotalCloud, does not cover installing certain prerequisites on the servers or workstations. This shortcoming means we must rely on SCCM when any service stack updates or additional prerequisites are needed."
"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."
"In TotalCloud, I would suggest improvements in policy checks to cater to various inventory types like VPCs, subnets, S3 buckets, or IAMs. There is a lack of data segregation according to criticality or inventory."
"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."
"The support process is inefficient due to the excessive number of replies required when submitting tickets."
"There is a lack of data segregation according to criticality or inventory."
"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."
"A feature improvement could be the inclusion of Windows OS support for container security, as it is currently only supported for Linux."
"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."
"The most challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."
"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."
"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."
"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."
"One area for improvement in Amazon Inspector is the automation aspect."
"There are challenges with the licensing policies, which are quite complicated."
"Defender could improve how data is represented. It can be unstructured or slow to load. The recent update allowing policy grouping into control groups is beneficial, but further enhancements for speed and clarity are needed."
"For improvements, I'd like to see more use cases integrated with Microsoft Sentinel and support for multi-cloud environments beyond just Azure."
"Customizing some of the compliance requirements based on individual needs seems like the biggest area of improvement. There should be an option to turn specific controls on and off based on how your solution is configured."
"Pricing could be improved. There are limited options based on pricing for the government."
"Microsoft can improve the pricing by offering a plan that is more cost-effective for small and medium organizations."
"The pricing could be better."
"The vulnerabilities are duplicated many times."
 

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."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"Qualys TotalCloud offers competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."
"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 good pricing that is affordable and competitive with the market. Our partnership also provides us with additional benefits."
"The cost is high, but it meets our organizational needs."
"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."
"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."
"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."
"I rate Microsoft Defender a three out of ten for affordability. The price could be a little lower."
"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 pricing and licensing of Microsoft Defender for Cloud have been good for us. We appreciate the licensing approach based on employee count rather than a big enterprise license."
"Pricing is a consideration, but we strive to keep costs low by enabling only necessary services."
"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."
"The licensing cost per server is $15 per month."
"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."
