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inside our AWS environment, and the problem is that the existing package deployed inside this EC2 instance has already outdated packages.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 Regarding the best features of Amazon Inspector, it gives us a list of all existing outdated packages as part of a deployed package on EC2 instances or specific Python packages that are part of the Docker file and the Docker image itself, which are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

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

"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 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."

"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 automated vulnerability detection aspect is most valuable."

More Amazon Inspector pros

"The integration with Logic Apps allows for automated responses to incidents."

"The pricing is good."

"Defender is user-friendly and provides decent visibility into threats."

"If you are a Microsoft organization and most of your organization uses Microsoft, Microsoft Defender for Cloud will be the best approach as it provides the easiest implementation to the most robust solution for a Microsoft suite."

"The most valuable feature is the hunting feature, which integrates well into the entire Microsoft ecosystem."

"Most importantly, it's an integrated solution. We not only have Defender for Cloud, but we also have Defender for Endpoint, Defender for Office 365, and Defender for Identity. It's an integrated, holistic solution."

"The most valuable feature for me is the variety of APIs available."

"I've seen benefits since implementing Microsoft Defender for Cloud. It's easy to manage for our large organization as an endpoint security solution. It integrates well with Office 365 and Windows 11, which is better than before. Patching, updates, and threat protection are all handled together now. Its AI features help predict threats."

More Microsoft Defender for Cloud pros

Cons

"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 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 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."

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

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

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

More Amazon Inspector cons

"The solution could extend its capabilities to other cloud providers. Right now, if you want to monitor a virtual machine on another cloud, you can do that. However, this cannot be done with other cloud platform services. I hope once that is available then Defender for Cloud will be a unified solution for all cloud platform services."

"An area where Microsoft Defender for Cloud could be improved is in getting away from having multiple menus that do the same thing, which seems imposing when looking at it."

"Most of the time, when we log into the support, we don't get a chance to interact with Microsoft employees directly, except having it go to outsource employees of Microsoft. The initial interaction has not been that great because outsourced companies cannot provide the kind of quality or technical expertise that we look for. We have a technical manager from Microsoft, but they are kind of average unless we make noise and ask them to escalate. We then can get the right people and the right solution, but it definitely takes time."

"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."

"I recommend that they extend the scope for legacy infra assets."

"Microsoft Defender for Cloud is not compatible with Linux machines."

"There should be an automated mechanism to design Azure policies based on the recommendations, possibly with AI integration. Instead of an engineer having to write a policy to fix security gaps, which is very time-consuming, there should be an inbuilt capability to auto-remediate everything and have proper control in place."

"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."

More Microsoft Defender for Cloud cons

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 pricing is very transparent and clear."

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

"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 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."

"This is a worldwide service and depending on the country, there will be different prices."

"I rate Microsoft Defender a three out of ten for affordability. The price could be a little lower."

"The solution is expensive, and I rate it a five to six out of ten."

"Microsoft Defender for Cloud is pricey, especially for Kubernetes clusters."

"I'm not privy to that information, but I know it's probably close to a million dollars a year."

"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."

"The cost is fair. There aren't any costs in addition to the standard licensing fee."
