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."

"Defender for Cloud Apps has given us good visibility regarding what we've allowed into our environment until now."

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

"The product helps us with privileged identity management to control who has access to what and for how long."

"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."

"The most valuable feature of Microsoft Defender for Cloud Apps is to stop shadow IT."

"The most valuable feature is the seamless integration across different clouds."

"All of the features are valuable because all of the features are related."

"The favorite feature of Microsoft Defender for Cloud Apps is the categorical blocking capability, which appears to be fed from Microsoft Security Intelligence feeds that seem to be better than other solutions and allows for dynamic configuration, cutting down on potential issues from manually managing block lists."

More Microsoft Defender for Cloud Apps pros

Cons

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

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

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

"The graph displayed in the Defender portal mostly doesn't capture the full picture as we see in endpoint-related or identity-related alerts; we can see a complete graph of what is happening there, but Microsoft Defender for Cloud Apps still falls short in capturing that whole aspect in the graph."

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

"There have been instances where the alerts generated have been false positives."

"There are some features, such as user navigation content filtering, that are disabled by default, and it probably makes sense to enable them by default."

"There could be more granular roles that are out of the box included in the product."

"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."

"Generally, the pricing can always be improved along with the management system."

"The technical support team has room for improvement."

Pricing and Cost Advice

Information not available

"We are an MST and we do not pay for the solution. However, the price of the solution could be better."

"This product is not expensive."

"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."

"The cost could be improved when you need to pay for anything. For example, refreshing files takes time to load, though it may be my Internet. To improve the refresh time, Microsoft says that we need to pay for a Premium license, and I don't like paying for things that help make a solution better."

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

"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."

"Where we are right now, this is an acceptable pricing. I would like to see more transparency given to the end user. The end user given to us is via the cloud service provider. There are different programs and license models. Some include this, and some include that. It is all over the place. There can be a little more consistency or simplification in the pricing so that your parts list is not ten pages long, and you are not trying to determine, "If I have an E3, does this cover that?", or "Do I need to pay separately for the license?" Simplification would probably be better."
