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…

Achieve comprehensive data protection with reliable performance and room for enhanced discovery accuracy

The product is still in a growing phase. I could see that many use cases in their product are not capable enough in terms of detecting or protecting. Compared to other products, they are in the middle of bringing their solution up to the mark, so it is not a full-grown solution. They have to get more accurate results in terms of data discovery and classification. The second thing is their support; support from Microsoft takes a lot of time to get a response from their support team. The third thing is their OCR capability is not that great in terms of identifying the documents. We would love to see response times of less than 24 hours. Additionally, there is no way to check the policy's current status in terms of whether it got synced or not. You have to wait and test the use cases after 24 hours or after 48 hours, and once it starts working, then it appears the policy got implemented.

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."

"Purview saves customers time by offering them a quick way to assess a situation and insights into how to improve."

"The reporting capabilities of Microsoft Purview are crucial. They provide insights into potentially non-compliant situations and suggest ways to rectify them. The solution helps to automate many tasks, allowing human operators to focus on areas where they offer the most value."

"The scalability of Microsoft Purview Information Protection is excellent."

"My favorite feature about Microsoft Purview Information Protection is that it generally applies to everything, so I don't have to go in and do it manually; I set a policy and then it applies."

"I think Purview is incredibly stable."

"The simplicity of the way we can configure the DLP rules in Microsoft Purview Information Protection is good."

"It is one of the advantages of the Microsoft solution that it provides a holistic way to manage the platforms and tools, so I do not have to use multiple information protection solutions."

"Purview is about auditing and discoverability. We need to ensure people aren't releasing information that they shouldn't and that they're doing multi-factor authentication or accessing it from the correct devices. It aids in reducing silos within organizations, enabling staff to easily find documents and contacts without exhausting human resources."

More Microsoft Purview Information Protection pros

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."

"I have not had much luck or much experience with the comprehensiveness of the data classification abilities in Microsoft Purview Information Protection, including identifying categories and sensitive information."

"I wouldn't recommend Microsoft Purview Information Protection for petabytes of documents as performance might be affected."

"I rate Microsoft support six out of 10. Response times are a challenge. It's hard to be an ambassador for a product when you know it will be hard to get support."

"Purview could better integrate with third-party tools, but I don't have a specific use case for that because It's currently integrated into the managed services we offer to Microsoft customers using E5 licenses."

"Microsoft Purview Information Protection can improve in terms of scan concurrency and scan processing time."

"I am concerned about its accuracy levels. Sometimes it throws a lot of false positives."

"There is potential for more integration in the use of AI."

"I see many options such as SharePoint Advanced Management for customers, but that requires a high investment from the customer's end in order to access the premium features of Purview, so it is not easy."

Pricing and Cost Advice

Information not available

"The price is determined by the enterprise licensing, either the E3 or E5 licensing or the EMS plus security and other feature licensing."

"The product is affordable, and our clients agree. Sensitivity labels come with the MIP license at an additional $2 a month per user, an excellent deal for auto-labeling capabilities."

"Initially, Purview's cost seemed quite high because it was for personal use. I was scanning a tiny tenant and thinking, "If I extrapolate this to an enterprise-scale tenant, it will be quite costly." However, I talked to people who had compared it to other products on the market, and they're spending five figures to get started. At least, Purview has a free trial, so you can try some of the features early on."

"The pricing and setup costs are transferred to my clients, who find it affordable and are satisfied with what they receive."

"The tool's pricing is fairly low, less than 100,000 for a year."

"The tool's pricing is not a problem for customers because they often purchase it as part of a bundle. With an E5 license, for example, users get access to the entire functionality. This is one of the main reasons why many customers are choosing Microsoft."
