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inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages.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 Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are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

Brings together cloud security insights through a unified view and supports agentless protection for virtual machines

Copilot and similar features are already being used, though not necessarily for Microsoft Defender for Cloud specifically. We are trying to get more experience before rolling out most of Microsoft Defender for Cloud's AI capabilities. This is definitely on our to-do list, and the priority is urgent as we seek to learn more about these capabilities. The GenAI threat protection from Microsoft Defender for Cloud has not been enabled yet. There are many unknowns with AI applications. AI agents will operate while you're not present, whether you are sleeping or awake, and it's unclear whether there would be any exfiltration of data or how data is being managed. Microsoft Purview is being used extensively, and there is significant development going on with DSPM that will be rolled out to address security concerns. Data labeling and proper demarcation for sensitivity of data before it is received are being actively pursued.

Quotes from Members

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

Pros

"The scalability of the solution itself is unparalleled."

"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."

"Amazon Inspector is highly stable, rated ten out of ten, and this stability impacts business security and administration positively."

"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 most valuable feature of Amazon Inspector is the categorization of findings, which filters vulnerabilities by instance, container image, container repository, and Lambda function."

"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 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."

More Amazon Inspector pros

"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 most valuable features offer the latest threat detection and response capabilities."

"The most valuable features are the security recommendations provided by Defender for Cloud."

"The security policy is the most valuable feature for us. We can go into the environment settings and attach any globally recognized framework like ISO or any benchmark."

"The valuable features include the ability to manage devices and the fact that Defender can replace other security tools like SCCM."

"Defender for Cloud is a plug-and-play solution that provides continuous posture management once enabled."

"Provides a very good view of the entire security setup of your organization."

"Microsoft Defender for Cloud has significantly enhanced our overall security posture by approximately 20 to 25 percent."

More Microsoft Defender for Cloud pros

Cons

"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."

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

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

"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 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."

More Amazon Inspector cons

"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."

"Microsoft has much room for improvement regarding the support for Microsoft Defender for Cloud. Their competitors are much better regarding support."

"The product's advanced analytics and reporting features could be improved."

"The most significant areas for improvement are in the security of our identity and endpoints and the posture of the cloud environment. Better protection for our cloud users and cloud apps is always welcome."

"One of the main challenges that we have been facing with Azure Security Center is the cost. The costs are really a complex calculation, e.g., to calculate the monthly costs. Azure is calculating on an hourly basis for use of the resource. Because of this, we found it really complex to promote what will be our costs for the next couple of months. I think if Azure could reduce the complex calculation and come up with straightforward cost mapping that would be very useful from a product point of view."

"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."

"Sometimes, it's very difficult to determine when I need Microsoft Defender for Cloud for a special resource group or certain kinds of products. That's not an issue directly with the product, though."

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

Pricing and Cost Advice

"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."

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

"The pricing is very transparent and clear."

"Pricing is difficult because each license has its own metrics and cost."

"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."

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

"Although I am outside of the discussion on budget and costing, I can say that the importance of security provided by this solution is of such importance that whatever the cost is, it is not a factor."

"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 product's pricing policy is generally favorable."

"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."

"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."

Overview

Amazon Inspector is an automated security assessment service that helps improve the security and compliance of applications deployed on AWS. Amazon Inspector automatically assesses applications for exposure, vulnerabilities, and deviations from best practices. After performing an assessment, Amazon Inspector produces a detailed list of security findings prioritized by level of severity. These findings can be reviewed directly or as part of detailed assessment reports which are available via the Amazon Inspector console or API.

Amazon Inspector security assessments help you check for unintended network accessibility of your Amazon EC2 instances and for vulnerabilities on those EC2 instances. Amazon Inspector assessments are offered to you as pre-defined rules packages mapped to common security best practices and vulnerability definitions. Examples of built-in rules include checking for access to your EC2 instances from the internet, remote root login being enabled, or vulnerable software versions installed. These rules are regularly updated by AWS security researchers.
