Executive SummaryUpdated on Oct 9, 2024

Amazon Inspector and Microsoft Defender Vulnerability Management are competing products in the category of vulnerability management. Microsoft Defender seems to have the upper hand due to its extensive feature set, despite Amazon Inspector's smooth AWS integration.

Features: Amazon Inspector provides automated security assessments, tight integration with AWS services, and a focus on cloud-native environments, making it ideal for AWS-centric organizations. Microsoft Defender offers comprehensive vulnerability coverage, integration across Windows environments, and robust threat intelligence features, appealing to businesses seeking extensive capabilities.

Room for Improvement: Amazon Inspector could improve by expanding support beyond AWS-centric environments, enhancing threat intelligence capabilities, and offering more detailed reporting features. Microsoft Defender could benefit from simplifying its deployment process, improving integration with non-Microsoft environments, and offering more customizable reporting options.

Ease of Deployment and Customer Service: Amazon Inspector benefits from quick deployment within AWS, facilitating straightforward integration for existing AWS customers. Microsoft Defender, while more comprehensive, requires more effort in deployment but offers extensive Microsoft ecosystem integration and support. Customers report Amazon Inspector is easier to deploy, but Defender's support services may offer better long-term value.

Pricing and ROI: Amazon Inspector typically presents a cost-effective solution for AWS users due to its usage-based pricing model. Microsoft Defender has a higher initial setup cost but justifies this with a rich feature set and comprehensive management capabilities. Organizations leveraging cloud-native and Microsoft solutions may find the ROI attractive despite the higher upfront costs. Amazon Inspector may appear more budget-friendly, while Microsoft Defender appeals to businesses seeking extensive vulnerability management features.

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inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages.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.

Ensures strong threat and vulnerability management with continuous risk assessment

The major priority is identity, which is crucial; we have lots of companies in manufacturing, energy, or various sectors, and it varies from one to another. I assess Microsoft Defender Vulnerability Management as very effective in continuously assessing vulnerabilities without requiring scans. We use automatic investigation and remediation features, safe attachments, safe links, and real-time reports, which are also very effective. For Active Directory, Defender has threat intelligence, and we are using that. The risk-based prioritization within Vulnerability Management affects my ability to manage vulnerabilities, particularly in relation to the Zero Trust Model utilized by our customers. The end-users often do as they please in their systems.

Quotes from Members

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

Pros

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

"The scalability of the solution itself is unparalleled."

"I recommend Amazon Inspector because it allows the automation of processes and requires less manual monitoring."

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

"The automated vulnerability detection aspect is most valuable."

"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 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 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."

More Amazon Inspector pros

"A valuable feature is the ease of management and integration with Microsoft products."

"Microsoft Defender Vulnerability Management is versatile and assesses vulnerabilities, providing detailed information on CVEs, their categories, and exploit statuses."

"The product's stability is very high...The scalability of the product is amazing."

"The integration with Sentinel has been one of the most valuable features for my organization."

"The solution is up-to-date and helps prevent zero-day attacks."

"Overall, I would rate Microsoft Defender Vulnerability Management a nine out of ten."

"One valuable feature is the Microsoft Security Scorecard."

More Microsoft Defender Vulnerability Management pros

Cons

"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."

"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."

"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."

"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."

"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."

More Amazon Inspector cons

"The automated remediations can be more specific."

"The documentation from Microsoft needs significant improvement. The documents are disorganized, with one document linking to another, making the steps unclear and difficult to follow."

"The general support could be improved."

"Probably my only criticism would be the cost. It is expensive."

"There should be risk scoring added to Microsoft Defender Vulnerability Management; specifically, they call it quantification of the risk."

"The constant changes in the product configuration or the console setup can sometimes be challenging."

"Regarding Microsoft's technical support, I would rate it a three out of ten; they could be more responsive and knowledgeable."

"It is expensive."

More Microsoft Defender Vulnerability Management cons

Pricing and Cost Advice

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

"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."

"The tool is a bit costly."

"I rate the product's price a three on a scale of one to ten, where one is a low price, and ten is a high price."

"The product’s pricing is medium."

"The licensing model follows a per-user per-month structure."

"The licensing costs are reasonable."

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.
