Enhanced visibility and exposes vulnerabilities but needs more integration

I am currently in the pilot stage of implementing Microsoft External Attack Surface Management (EASM). My organization is transitioning to a comprehensive track of Microsoft solutions, and we will move to full-scale production in another year, maybe Microsoft External Attack Surface Management…

Deployment has been seamless with insightful data categorization and enhanced control

The features of Microsoft Defender for Cloud Apps that I have found most valuable include the overall portal view, with bubble graphs which give us insight into what goes where in the categorization, nowadays with Generative AI but all kinds of categorization, collaboration, etc. That central view of the portal is very useful for us. The impact of Microsoft Defender for Cloud Apps on our organization's ability to assess and manage app related risks has been significant because we have more visibility. Therefore, we can add more control, and we have already done so. This was not possible in the old solution, in the old CASB solution with Netskope. We now can see on the spot, and we do that almost weekly, what the end users are utilizing, which cloud providers or cloud apps they're using. The visibility into OAuth apps provided by Microsoft Defender for Cloud Apps is very good. The visibility into risk and risk management of our organization's Generative AI apps is very nice, as you can choose the category Generative AI and then see exactly what traffic has been going to and from Generative AI in the cloud. This makes us very insightful on what is used within the company. We have some policies on blocking specific Generative AI, and we use within our company one particular AI part, which is CoPilot of Microsoft. In this way, we can see what the end users are using other than CoPilot, and that makes us more in control. The effectiveness of the integration of Microsoft Defender for Cloud Apps with Defender XDR and defending against SaaS attacks is very intuitive. It works immediately if we create a new policy or in Purview or in Microsoft Defender for Cloud Apps, or when we make an app unsanctioned by blocking it, then it is almost immediately, or at least within a couple of hours, effective on all the endpoints where the EDR is running. This gives us much better control over things than before.

Quotes from Members

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

Pros

"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."

"It seems to be better at protecting from cyberattacks."

"We have become more aware of what services our users are using, how often they are using them, and what data is being sent out of the organization and to which services. So, it is really a lot about visibility and helping us make decisions based on that. It drives some of our policy decisions for adding extra security controls."

"The ability to prevent users from using certain applications is one of the most valuable features. It doesn't require any configuration for implementation from the client perspective. It just works right away and gives you the information you need."

"Everything from Microsoft is integrated. You receive regular reports on them all. You can push your reports, logs, and security alerts, which are all integrated. It is crucial that these solutions work natively together to deliver coordinated detection and response across our environment."

"Microsoft Defender for Cloud Apps is very comprehensive, providing a complete 360-degree view of applications within an organization."

"I like the web GUI/the management interface. I also like the security of Microsoft. As compared to other manufacturers, it's less complex and easy to understand and work with."

"On-demand scanning is the most valuable feature. In addition, it's a fairly fluid product. It syncs back to the cloud and provides metrics. It's pretty intelligent."

"Defender for Cloud Apps has given us good visibility regarding what we've allowed in our environment until now. It helps us to know our inventory, understand what our customers are using, and steer them toward safer practices."

"It is very easy to use, which is what we look for in these types of solutions."

Cons

"The integration is not as seamless compared to competitors like Palo Alto."

"Further integration across different Microsoft products would be an improvement."

"With Microsoft, support is always crazy, it's not easy to get support."

"We would like to get more information from the endpoint. I don't get enough detailed information right now on why something failed. There is not enough visibility."

"Defender could integrate better with multi-cloud and hybrid environments. It requires some additional configuration to ingest data from non-Azure environments and integrate it with Sentinel."

"Microsoft Defender for Cloud Apps’s technical support services needs improvement."

"There are certain areas where the product could improve, such as some functionalities that did not work as expected."

"I would like for it to be available on Mac and for it to support all of the features of Microsoft financing products. It is really for Windows."

"Sometimes the support is actually lacking."

"In the future, I would like to see more plug-and-play capabilities that use AI to tell you what needs to be done. It would be helpful if it scanned our devices and made security suggestions, on a configuration basis."

"We are having trouble with our continuous reporting configuration and struggling with configuring the collector properly with our log parsing. We've also faced difficulties getting support for this issue. It's taken us months to figure this out after going through a couple of different support channels."

Pricing and Cost Advice

Information not available

"This product is not expensive."

"It has pretty good pricing."

"Its pricing is on the higher side. Its price is definitely very high for a small-scale company. As an enterprise client, we do get benefits from Microsoft. We get a discounted price because of the number of users we have in our company. We have a premier package, and with that, we do get a lot of discounts. There are no additional costs. It only comes in the top-tier packages. Generally, the top-tier license is the best license that you can get for your organization. If you want, you can buy it separately, but that's not a good idea."

"We utilize the Microsoft E5 licensing, which encompasses the entire Microsoft suite; however, it is costly."

"Our clients normally use the Microsoft E1 licensing, which is renewed yearly."

"The pricing is fair."

"The price could be better and should be reconsidered."

"Microsoft offers bundle discounts and a pay-as-you-go option."
