Product deployment protects assets but needs improvement in system support
I am doing maintenance for Microsoft Defender for Business, and I'm currently working with it. We don't need to use the latest version of Microsoft Defender for Business. We still use the latest virus definition file that Microsoft Defender for Business has automatically updated. We implement a basic update mechanism. Our compliance division manages how many servers and PCs we have and whether those servers have antivirus solutions. I am not certain about how Microsoft Defender for Business helps with AI-driven security strategies. I just use it normally and don't know if it uses AI technology. I rate Microsoft Defender for Business a six out of ten.

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

"Because Microsoft Defender for Business is a native solution to Microsoft 365, it has contributed to my organization's proactive defense strategies by saving time on integration."
"Microsoft Defender for Business stands out due to its ease of use, particularly due to the fact that many of my customers already use Microsoft and Azure."
"Microsoft Defender for Business works well with the Microsoft Azure Security ecosystem, including Defender for Endpoint and Office 365 Cloud."
"If you're an Intune user, you can bring in certain capabilities like system-hardening policies, which further enhances the security."
"The security features in Microsoft Defender for Business that have been most effective for our company include the way it's built-in and intertwined into all the operating systems, giving us a good opportunity to holistically block things for the organization using that tenant."
"I would recommend Microsoft Defender for Business to others, rating it as ten out of ten."
"Microsoft Defender for Business stands out due to its ease of use, particularly due to the fact that many of my customers already use Microsoft and Azure."
"The most effective features of Microsoft Defender for Business include its threat detection and response capabilities in managing vulnerabilities and ransomware attacks."
"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."
"The system is stable; I haven't encountered any worldwide stability issues unlike other office products."
 

Cons

"We faced some issues while running some applications on Mac."
"The user interface has a lot of features which can make it complex and hard to adapt to for some users."
"The biggest one is that Defender needs to be more proactive to the emerging threats. There can be tighter integration with email, especially how it integrates with our email system, which is the Microsoft Outlook suite. There should be the ability to react a lot quicker to emerging threats because sometimes, it takes a few days before some of these new threats are fully identified, and we need that to be a few hours."
"The threat detection capabilities require significant customization for multistage threat detection."
"I see room for improvement in Microsoft Defender for Business, particularly regarding the consolidation of all security solutions in one place and the integration of AI and data security into the same platform."
"If I need logs and don't have local storage bundled with Defender, I need to add workspace and log analytics, which is costly for storing logs of 2 GB, 5 GB, 10 GB."
"Defender's reporting is rather scattered, and its URL filtering mechanism doesn't really work."
"Defender's threat protection should be fine-tuned to reduce false positives. It could be more targeted, reflecting a continuous evolution in detecting. Also, it could be easier to integrate into other environments."
"Microsoft's Purview Data Lifecycle Management preview features can be unreliable, hindering their usefulness."
"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."
"I think labeling could use a lot more AI assistance. AI implementation into labeling would be beneficial."
 

Pricing and Cost Advice

"Defender for Business is included by default with an Office 365 premium subscription."
"The tool is cheap, while some other solutions are more expensive. I remember the tool cost about five euros for a workstation or for a user on a monthly basis."
"The tool's cost has been a little high, but I do not think it was terrible."
"Since we're a nonprofit, we get pretty good discounts on the tool."
"It has to get more competitive because we are starting to see some of the competitors providing better pricing, and some of it, of course, is to gain market share. The Defender product pricing is probably a little higher than the competitors."
"The service operates on a pay-as-you-go basis, charging an extra one cent per field of metadata scanned in our data."
