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…
Abdulrahman Muhammadi - PeerSpot reviewer

Integration with existing cloud workflows has simplified compliance and threat detection
Licensing cost is a significant concern. With Defender Plan 1, Microsoft Defender for Cloud Apps comes with a pay-per-use model. Each feature has its own pricing when activated on VMs. For example, the vulnerability assessment has separate pricing, the base model including encryptions has separate pricing, and the compliance features have separate pricing. This applies to each VM and Azure resource individually. It is not straightforward where you can take one license and apply it to everything. Each feature has its own pricing model which can be tedious, as the costs keep accumulating. The only lacking feature currently is XDR (extended detection and response). Apart from that, I have only positive experiences with the whole Microsoft suite, except for the pricing structure.

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's integration with our identity solutions is critical in our current setup."
"The integration within the entire Defender suite is highly valuable because it allows for communication between different components and offers pretty decent correlations."
"The compliance capabilities of Microsoft Defender for Cloud Apps are quite extensive."
"The most valuable feature is the ease of management; the management is cloud-based and we can work inside or outside on public networks."
"It is very easy to use, which is what we look for in these types of solutions."
"After creating the policy you can be assured that a user's data is being protected."
"In Microsoft Defender for Cloud Apps, there is an option to enable files. Once you enable that, it will give you all the files in your organization and where they are located in the cloud... That feature is very useful for investigation purposes."
"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."
 

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."
"It doesn't actually decrease the time to respond. This has been an issue with Microsoft recently. Sometimes, there is a delay when it comes to getting an alert policy email... Sometimes it takes two or three hours for that email to be sent."
"The technical support team has room for improvement."
"Since implementing this solution, we have had more support calls regarding false positives."
"I would prefer to have filtering options incorporated within the policies, enabling the solution to perform tasks beyond mere blocking or allowing."
"Defender for Cloud Apps could come with more configured policies out of the box. Also, integration could be easier. Integration is moderately difficult because Microsoft hasn't developed a solution that unifies device onboarding and management. You have to use Intune to manage devices and Defender for Endpoint to enforce policies. They need to fix their integration, but I believe they will straighten it out by the end of the year."
"We sometimes get errors when we create policies, which is somewhat annoying because some policies stop working due to misconfigurations. We find this challenging because it limits our options for troubleshooting an issue."
"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've had an issue where an in-session policy was not working."
 

Pricing and Cost Advice

Information not available
"This product is not expensive."
"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 fair."
"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."
"The product's pricing seems fair."
"We utilize the Microsoft E5 licensing, which encompasses the entire Microsoft suite; however, it is costly."
"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 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."
