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inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages.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 Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are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

"If I had to say something positive about the product that brings me the biggest benefit, I would say it has accurate reports, gets new update CVEs, zero-day attack detection, and is easy to manage with its GUI."

"It is a cloud-native app that integrates with both IaaS and SaaS. It seamlessly integrates with other platforms."

"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."

"TotalCloud provides the easiest and the best approach for cloud infrastructure management."

"Qualys TotalCloud has improved our security posture."

"TruRisk Insights is the most important innovation they've released this year."

"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."

"The best feature would be the ability to create policies. It is easy to control and update policies as required."

More Qualys TotalCloud pros

"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."

"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."

"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."

"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 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."

More Amazon Inspector pros

"When we started out, our secure score was pretty low, we adopted some of the recommendations that Security Center set out and we were able to make good progress on improving it, as it had been in the low thirties and is now in the upper eighties."

"The pricing is good."

"The solution is used for risks, vulnerabilities, and compliance."

"It alerts us to our vulnerabilities and ensures compliance by marking off a compliance tool checklist."

"The first valuable feature was the fact that it gave us a list of everything that users were surfing on the web. Having the list, we could make decisions about those sites."

"The solution has improved our organization in terms of benchmarking, our Secure Score has improved a lot, and we're compliant with particular benchmarks."

"Good compliance policies."

"It's got a lot of great features."

More Microsoft Defender for Cloud pros

Cons

"In a future release, I suggest that zero-day vulnerabilities should be predicted in advance using AI technologies. The system is not 100% secure yet, so proactive threat hunting could be enhanced to be more proactive than the current system."

"I sometimes have difficulty detecting or uninstalling certain versions of applications, which I have to do manually."

"The downside is only in container security, but it has not been a long time since they introduced these models."

"There is room for improvement in the support."

"To be honest, I would move out from this tool because it does not give a full view of vulnerability."

"The support is not up to the mark and seems to be overburdened."

"From a downside perspective, the UI is not user-friendly and feels dated compared to other tools like Prisma Cloud."

"Their customer support needs improvement."

More Qualys TotalCloud cons

"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."

"One area for improvement in Amazon Inspector is the automation aspect."

"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 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."

"The most challenging aspect I faced with Amazon Inspector during integration was automating the remediation process."

"It has automated vulnerability assessment, yet I seek more flexibility in defining custom vulnerability checks tailored to my needs, which is more difficult."

"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 false positive rate of Amazon Inspector is a little high, and it is not covering all different applications and scanning."

More Amazon Inspector cons

"The product was a bit complex to set up earlier, however, it is a bit streamlined now."

"We haven't experienced issues with Microsoft Defender for Cloud for our company size of about five hundred people. However, I've heard there might be issues with scalability for larger enterprises."

"The pricing could be improved, as it is somewhat high for smaller companies."

"Most customer teams need more training on this type of product."

"Defender for Cloud is pretty costly for a single line. It's incredibly high to pay monthly for security per server."

"Sometimes if you do not have the resources in-house, it can be difficult."

"Defender is occasionally unreliable. It isn't 100% efficient in terms of antivirus detection, but it isn't an issue most of the time. It's also somewhat difficult to train new security analysts to use Defender."

"After getting a recommendation, it takes time for the solution to refresh properly to show that the problem has been eliminated."

Pricing and Cost Advice

"Qualys TotalCloud offers cost-effective licensing flexibility."

"The pricing for TotalCloud is attractive and competitive in the market. Given the features, especially the dashboard, I have no concerns regarding pricing."

"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."

"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 competitive pricing given its comprehensive suite of features, including integration, assessment, remediation, and detection capabilities, all within a single platform."

"Qualys TotalCloud is cost-efficient and was selected for its value compared to other products."

"The pricing is comparable. It is built into our other product, so I cannot piecemeal it. It is a part of our subscription."

"As a middle management member, I do not have direct pricing knowledge, but based on the knowledge from our meetings, its pricing is competitive."

More Qualys TotalCloud pricing and cost advice

"It's priced according to market standards for its services."

"The pricing is very transparent and clear."

"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 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 is a helpful cost-reducing option that allows you to integrate production subscriptions with non-production subscriptions."

"We are using the free version of the Azure Security Center."

"Currently, Microsoft offers only one plan at the enterprise level which is $15 per machine."

"Pricing is a consideration, but we strive to keep costs low by enabling only necessary services."

"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."

"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."

"We only use the free tier, so we haven't faced any pricing, setup costs, or licensing challenges."
