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

"It seems to be better at protecting from cyberattacks."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"Defender's integration with our identity solutions is critical in our current setup."
"I like the alert policies because they are quite robust. It has some built-in templates that we can easily pick up. One of them is the alert for mass downloads, when a particular user is running a massive download on your SharePoint site."
"The most valuable feature of Microsoft Defender for Cloud Apps is that we are primarily using only the Defender for Cloud on the Azure Cloud."
"It's a full engine that you can use to discover all your assets in the cloud, whether they are on a public cloud or a private cloud."
"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."
"The ability to sanction unsanctioned apps using Secure Score benchmarking, included in Cloud, is also beneficial."
"In summary, we have just begun using this product but so far, it works well and we are satisfied with it."
"The solution is bundled with E3 and E5 licenses; that's the reason it's most commonly deployed, as it's part of the bundle and not a separate cost, and if your business requirements are relatively simple, it can get the job done."
 

Cons

"Further integration across different Microsoft products would be an improvement."
"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."
"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."
"Since implementing this solution, we have had more support calls regarding 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."
"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."
"There could be more granular roles that are out of the box included in the product."
"However, the price of the solution could be better."
"MCAS doesn't have many reporting capabilities, and it's really an operational nightmare to get all these things done at this point in time by using MCAS."
"It is a new thing for Microsoft, and it still has a lot of room to improve."
 

Pricing and Cost Advice

Information not available
"The pricing is fair."
"This product is not expensive."
"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."
"We are an MST and we do not pay for the solution. However, the price of the solution could be better."
"I'm not totally involved in the pricing part, but I think its pricing is quite aggressive, and its price is quite similar to Netskope. Netskope has separate licensing fees or additional charges if you want to monitor certain SaaS services, whereas, with MCAS, you get 5,000 applications with their Office 365. It is all bundled, and there's no cost for using that. You only have the operational costs. In the country I am in, it is a bit difficult to get people with the required skill sets."
"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."
"It has pretty good pricing."
"Our clients normally use the Microsoft E1 licensing, which is renewed yearly."
