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."
"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."
"Microsoft Defender for Cloud Apps is very comprehensive, providing a complete 360-degree view of applications within an organization."
"Defender helps us control which applications are being used and gain more security insight into remote and hybrid users based on user identity and log in location. You can also integrate Defender for Cloud Apps with Defender for Endpoint to extend its capabilities."
"From a security monitoring perspective, there is a productivity improvement and fewer human errors."
"The most valuable feature is the alerting system."
"All of the features are valuable because all of the features are related."
"The solution is helping a lot; we get very detailed reporting on security that really shows what users are doing, including what they've opened, what they're sharing, downloading, viewing, and when they are logging in."
"It gives our clients a sense of confidence that in case there are activities on some of their applications, they will get an alert and the issue will be mitigated, based on the action that has been set."
"Defender's integration with our identity solutions is critical in our current setup."
 

Cons

"Further integration across different Microsoft products would be an improvement."
"The integration is not as seamless compared to competitors like Palo Alto."
"With Microsoft, support is always crazy, it's not easy to get support."
"This service would be better if it had a separate license, only for this service, that could be used to track usage."
"I believe it's only set to be integrated with Microsoft Defender for identity and identity protection. I would like to see it available for use with something like Office 365 Defender. I don't think it's integrated with that yet."
"Currently, reporting is not very straightforward and it needs to be enhanced. Specific reports are not included and you need to run a query, drill down, and then export it and share it."
"The product is very good so far, however, it would be better if it could include more up-to-date threat protection."
"It takes some time to scan and apply the policies when there is some sensitive information. After it applies the policies, it works, but there is a delay. This is something for which we are working with Microsoft."
"If you have more elaborate needs or if you have some more sophisticated use cases, for example, if you need an in-line component, or if you need to distinguish between sanctioned and unsanctioned applications, this solution doesn't cut it."
"A significant improvement I would like to see is the integration into a single pane of glass, which would allow me to view everything in one place rather than having to switch between different areas."
"The insights could be improved, especially in reporting."
 

Pricing and Cost Advice

Information not available
"It has fair pricing. You pay for what you get. As far as I know, there are no costs in addition to the standard licensing fee."
"Our clients normally use the Microsoft E1 licensing, which is renewed yearly."
"We utilize the Microsoft E5 licensing, which encompasses the entire Microsoft suite; however, it is costly."
"The product's pricing seems fair."
"The pricing is in the middle. It isn't too cheap or expensive compared to other antivirus or security products. It is priced according to industry standards."
"The pricing is a little bit high but right now, we are okay with it because of the compatibility with Office 365, Teams, and Azure AD."
"The pricing is fair."
"We are an MST and we do not pay for the solution. However, the price of the solution could be better."
