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inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages.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 Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are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 has been excellent in providing us with immediate access to all the products and features we need, such as CSPM, TruRisk Insights, and compliance reports, including CIS and HIPAA."
"Qualys TotalCloud has significantly improved our organization by automating our reporting processes, reducing the time spent on report creation from two hours to less than fifteen to twenty minutes."
"Qualys TotalCloud's most valuable features are its security capabilities that help identify and mitigate risk factors."
"The vulnerability management feature is the one I like the most because it provides a clear picture of all vulnerabilities."
"TotalCloud provides the easiest and the best approach for cloud infrastructure management."
"The agent and agentless scanning in TotalCloud, particularly the FlexScan method, is incredibly valuable. With traditional scanning approaches, we had to give IP ranges and whitelist IPs. All that is now simplified. FlexScan requires minimal intervention, and after configuration, it automatically collects data and performs necessary scans."
"Vulnerability and threat detection and assessment of the criticality of the vulnerabilities exposed are most valuable."
"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."
"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 scalability of the solution itself is unparalleled."
"The most valuable feature of Amazon Inspector is the categorization of findings, which filters vulnerabilities by instance, container image, container repository, and Lambda function."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"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 automated vulnerability detection aspect is most valuable."
"The solution's coordinated detection and response across devices and identities is impressive because it is complete."
"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."
"The most valuable features are the security recommendations provided by Defender for Cloud."
"The biggest benefit of Microsoft Defender for Cloud for us is specifically around being able to identify threats very quickly and being able to shut them down."
"Defender for Cloud has improved our security posture, providing us with a prioritized list of security issues to remedy, which improves our security operations because we know what to tackle first."
"Microsoft Defender for Cloud has definitely helped us manage and secure our multi-cloud environment by providing ease of use."
"Microsoft Defender for Cloud helps in improving our overall security posture. We have a nice overview of what is missing where and what can be improved."
"The features of Microsoft Defender for Cloud that I like the most are the regulatory compliance capabilities; these features have benefited my organization by improving our overall security posture."
 

Cons

"Their support could be improved."
"There is a lack of data segregation according to criticality or inventory."
"Areas that need improvement in every solution include the remediation part. The remediation steps should be simple enough for everyone to understand."
"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."
"I think Qualys TotalCloud needs to improve its handling of zero-day vulnerabilities and supply chain management because modern ransomware attacks not only target prime critical infrastructures but also the supply chain system."
"An area for improvement would be to focus on risks related to AI, such as large language models and potential data leakage."
"The cloud licensing unit system is unclear, especially since "units" aren't well-defined."
"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."
"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."
"There are challenges associated with the interdependencies in AWS services, like requiring an Active Directory for other services, resulting in additional charges."
"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."
"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."
"The most challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."
"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."
"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."
"Microsoft Defender for Cloud is not compatible with Linux machines."
"The product was a bit complex to set up earlier, however, it is a bit streamlined now."
"Agent features need to be improved. Sometimes, we are not able to get correct signals from the machines on which we have installed these agents."
"Defender could provide more in-depth visibility into vulnerabilities and services. For instance, we wanted to scan Azure NetApp for sensitive data, but they didn't have that feature. It was only for storage accounts. I want Azure Defender features to cover all Azure resources rather than a few."
"As an analyst, there is no way to configure or create a playbook to automate the process of flagging suspicious domains."
"Another thing that could be improved was that they could recommend processes on how to react to alerts, or recommend best practices based on how other organizations do things if they receive an alert about XYZ."
"After getting a recommendation, it takes time for the solution to refresh properly to show that the problem has been eliminated."
"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."
 

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."
"The cost is high, but it meets our organizational needs."
"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."
"It isn't cheap, but it's reasonable. It helps us to manage things with very few resources."
"While Qualys TotalCloud's pricing is currently acceptable, it is becoming increasingly expensive and may soon be considered overpriced."
"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."
"Qualys TotalCloud is expensive, but it offers a premier solution with no headaches."
"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."
"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."
"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 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."
"They have a free version, but the license for this one isn't too high. It's free to start with, and you're charged for using it beyond 30 days. Some other pieces of Defender are charged based on usage, so you will be charged more for a high volume of transactions. I believe Defender for Cloud is a daily charge based on Azure's App Service Pricing."
"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."
"Pricing is difficult because each license has its own metrics and cost."
"I rate Microsoft Defender a three out of ten for affordability. The price could be a little lower."
"Its pricing is a little bit high in terms of Azure Security Center, but the good thing is that we don't need to maintain and deploy it. So, while the pricing is high, it is native to Azure which is why we prefer using this tool."
"The licensing cost per server is $15 per month."
"Security Center charges $15 per resource for any workload that you onboard into it. They charge per VM or per data-base server or per application. It's not like Microsoft 365 licensing, where there are levels like E3 and E5. Security Center is pretty straightforward."
