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inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages.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 Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are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

Continuous posture management has improved cloud risk visibility and accelerated remediation
The best features Microsoft Defender for Cloud offers are the CSPM, which includes continuous posture assessment with prioritized misconfiguration fixes that gives us clear visibility of cloud risk and drift across the environment. Additionally, the CWPP has strong runtime protection for VMs, containers, and PaaS, including multi-cloud visibility. The single pane for Azure, AWS plus GCP with consistent policies and recommendations is noteworthy. What stands out most is the combination of posture management plus runtime protection, which provides both preventive and detective control in one platform. Since using Microsoft Defender for Cloud, we have seen a positive impact such as improved security posture with clear visibility via secure score that helped reduce misconfiguration significantly over time. There has also been faster risk remediation, as we have prioritized recommendations plus auto remediation which has reduced fix time from days to hours for common issues. Better workload protection has resulted in earlier detection of suspicious activity on VMs or containers, preventing potential compromise and lateral movement. The biggest impact is proactive risk reduction plus faster remediation across cloud environments. From our experience, misconfiguration has been reduced to a 40 to 55% drop in critical issues such as public exposures, weak NSG, and IAM gaps within the first few months after continuous tuning. We have saved time with the remediation time reduced by 50 to 60%, or from days to a few hours using prioritized recommendations plus auto remediation. Additionally, secure score improvement has typically risen from a 50 to 55% baseline to 80 to 85% after structured remediation cycles, which were measured by tracking secure score trends, the number of open recommendations, and mean time to remediate.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The automated vulnerability detection aspect is most valuable."
"It operates continuously, so as soon as resources are created, it scans them for vulnerabilities."
"The scalability of the solution itself is unparalleled."
"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 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."
"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."
"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."
"The most valuable feature is the regulatory compliance aspect, where we utilize predefined initiatives like NIST."
"I have not experienced any difficulties or issues with the stability of Microsoft Defender for Cloud."
"The scalability of Microsoft Defender for Cloud is very good."
"When you have commissioned Defender, you have these things visible already on your dashboard, which gives the efficiency to the people to do their actual work rather than bothering about emails or ITSM tools, resulting in fewer costs with a more optimized, easier-to-use solution and providing operational efficiency for your team from day one."
"It has improved our security posture a lot, and with the implementation of Azure Security Center, we have resolved many issues, including being able to do security monitoring of the complete infrastructure across both cloud and on-prem environments."
"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."
"Compared to other products, Azure Defender's main advantage is native integration with all Azure services."
"It helps you to identify the gaps in your solution and remediate them. It produces a compliance checklist against known standards such as ISO 27001, HIPAA, iTrust, etc."
 

Cons

"One area for improvement in Amazon Inspector is the automation aspect."
"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."
"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 are challenges associated with the interdependencies in AWS services, like requiring an Active Directory for other services, resulting in additional charges."
"There is room for improvement in the scanning capabilities. I'd like to see broader coverage in terms of the vulnerabilities detected."
"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."
"Microsoft sources most of their threat intelligence internally, but I think they should open themselves up to bodies that provide threat intelligence to build a better engine."
"The cost is always a concern, but overall, it's not too bad because it is easy to use and pretty friendly."
"However, some Copilot features aren't available in the GCP environment. This is something we hope will be addressed in the future."
"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."
"The overview provides you with good information, but if you want more details, there is a lot more customization to do, which requires knowledge of the other supporting solutions."
"To improve Microsoft Defender for Cloud, I think pricing-wise, the license price is a little bit higher from an ingestion cost perspective."
"After getting a recommendation, it takes time for the solution to refresh properly to show that the problem has been eliminated."
"I felt that there was disconnection in terms of understanding the UI. The communication for moving from the old UI to the new UI could be improved. It was a bit awkward."
 

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."
"Microsoft's licensing and pricing are sometimes complicated. If someone is new to Microsoft's licensing, they might have difficulty with it."
"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."
"There is a helpful cost-reducing option that allows you to integrate production subscriptions with non-production subscriptions."
"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."
"Microsoft Defender for Cloud is pricey, especially for Kubernetes clusters."
"The tool is pretty expensive."
"While we pay for any additional features, the pricing seems competitive, though I am not involved in the specific cost details."
"Pricing depends on your workload size, but it is very cheap. If you're talking about virtual machines, it is $5 or something for each machine, which is minimal. If you go for some agent-based solution for every virtual machine, then you need to pay the same thing or more than that. For an on-premises solution like this, we were paying around $30 to $50 based on size. With Defender, Microsoft doesn't bother about the size. You pay based on the number of machines. So, if you have 10 virtual machines, and 10 virtual machines are being monitored, you are paying based on that rather than the size of the virtual machine. Thus, you are paying for the number of units rather than paying for the size of your units."
