Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.

A comprehensive data management solution shows potential for improvement while providing strong integration with existing infrastructure
One of the requirements is to have data leak policies and data access policies. This is very critical to enforce data governance standards, which relate to data classification, access control, data protection, and retention. It covers the entire lifecycle, helping us to protect, detect, and classify the documents. Challenges are mostly related to the security products onboarded into the bank; they have challenges in terms of those products complying with the internal standards. Sometimes, we cannot just use the DLP across the state. For example, using Microsoft products has been easy to adopt, such as OneDrive and SharePoint on-premise, but it becomes a challenge when it comes to AWS, as data also exists in S3 buckets. Testing is still ongoing, but it will eventually be done. The time it takes to scan is one issue; when we raise high-volume issues and tickets related to scanning failures, it relates to permission errors, which are technical challenges. These take time because we have high volume tickets in terms of connectivity, scanning failures, and related matters. There are also frequent change requests, especially regarding scoping or rescoping due to complexities, creating several challenges. In both organizations I work with, there are gaps, and there is no enterprise-wide data classification available. However, there are pockets of implementations for various products. Some agencies are using it, but otherwise, there's no product existing across the enterprise. Microsoft Purview Data Lifecycle Management is definitely a good solution, but there is significant room for improvement from a product perspective. Reporting is another area that needs improvement.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
"There are several features that I consider valuable."
"The most valuable feature of Microsoft Defender for Office 365 is data backups that we can provide through ticket requests."
"The good part is that you don't have to configure it, which is very convenient."
"One of our clients didn't have the budget to invest in a SOC team, but we deployed the solution for them, and they now run a SOC with only one analyst."
"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"Technical support is very good. They are knowledgeable and respond quickly."
"Defender has reduced the time our security team spends on tasks by 10 to 15 percent, allowing us to focus on other areas."
"The system is stable; I haven't encountered any worldwide stability issues unlike other office products."
"The impact of Microsoft Purview Data Lifecycle Management on my unified data catalog has improved a lot; the improvements I see are in the lineage, the discovery, and the labeling."
"The UI is the most valuable feature."
"HPE Apollo Systems has positively impacted our organization by improving business operations by eighty percent, saving time, improving efficiency, and facilitating the management of large data sets."
 

Cons

"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."
"The only thing they should improve is the licensing model. They should stop changing it. A year ago, the five features I mentioned were included in one product. Now, three of them are bundled into one product, and you have to pay extra for the other two. I don't mind paying extra, but I don't want them to change it every year or every six months. I need to know what I'm looking at and not worry about it next year."
"Its price should be improved. Its cost is a major concern for us."
"Configuration requires going to a lot of places rather than just accessing one tab."
"Sometimes I have to recategorize things when it takes the wrong step and I do not want it to classify something as suspicious."
"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."
"I think labeling could use a lot more AI assistance. AI implementation into labeling would be beneficial."
"The time it takes to scan is one issue; when we raise high-volume issues and tickets related to scanning failures, it relates to permission errors, which are technical challenges."
"Microsoft's Purview Data Lifecycle Management preview features can be unreliable, hindering their usefulness."
"There is no specific improvement I would suggest for Microsoft Purview Data Lifecycle Management, but I think if they can work on policy design and usability, adding more granular control for the organization regarding controlling the movement of data outside would definitely improve the solution."
 

Pricing and Cost Advice

"I was working in the government and it was too expensive for us to use our Microsoft products."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."
"The pricing is normal. Considering its popularity, it's not overpriced."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"The license is expensive because the cost is based on the number of users."
"The product is expensive."
"The service operates on a pay-as-you-go basis, charging an extra one cent per field of metadata scanned in our data."
