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.

Integrated auditing has strengthened data retention and improved incident investigations
I have seen areas for improvement, specifically in Microsoft Purview Audit or in general about Microsoft. I have had a situation with documentation. I had a customer who wanted to create alerts and they had Microsoft 365 Business Premium. In the documentation, it was noted that this license is enough for creating alerts. When we tried to make them, we noticed they cannot do it with Microsoft 365 E3 because the customer had limited features to manage alerts. The customer had to buy E3. We created Microsoft support requests, and they confirmed that the documentation displayed not the real situation and they have been going to update documentation. The same situation occurred now with implementing Microsoft Purview Audit in the last autumn. eDiscovery was combined with search and content search, and the documentation was not clear at the beginning. It was a little difficult to describe to customers that now it is a part of eDiscovery. Content search is a very simple functionality, while eDiscovery is a little difficult. I am not entirely sure why Microsoft is going in the way of combining these services because they are the same. However, for a customer who has never seen these services, it is difficult to understand quickly. The same situation occurs with litigation holds and some other holds. For any mail, I am trying to keep data. For example, emails are held for a year or two years, ten years, it does not matter. It is difficult to understand where to find this data and where these emails are being held. I need to use eDiscovery to find out all deleted data that was kept somewhere in some hidden folders of the mailbox. Regular customers and regular administrators know that on-premises Exchange, for example, allows them to find the data in some repository and review the list of kept data. However, with this hold, we do not have any functionality to review the list of kept data. It is difficult to understand for customers how to work with this. I had a case where I spent three or four hours working deeply with a customer to explain how to work with eDiscovery, why Content Search is not there when it was before, what is an eDiscovery case, and why we are talking about all of this just to review a list of kept emails. This is difficult.

"The platform has significantly enhanced our operational insight into the overall Microsoft 365 environment."
"We're easily saving at least one hour per day using this solution."
 

Cons

"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."
"The user interface has a lot of features which can make it complex and hard to adapt to for some users."
"Defender's reporting is rather scattered, and its URL filtering mechanism doesn't really work."
"The threat detection capabilities require significant customization for multistage threat detection."
"The tool's support is an area of concern where improvements are needed."
"We faced some issues while running some applications on Mac."
"Pricing could be lowered as it is expensive and not suitable for low-budget organizations."
"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."
"I had a case where I spent three or four hours working deeply with a customer to explain how to work with eDiscovery, why Content Search is not there when it was before, what is an eDiscovery case, and why we are talking about all of this just to review a list of kept emails."
"We do have a Denial of Access happening."
"We are still in the early stages of leveraging Microsoft Purview Audit. Currently, it's primarily used for the audit function."
"Areas for product improvement include enhancing customization options and integrating more comprehensive compliance features."
 

Pricing and Cost Advice

"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."
"Defender for Business is included by default with an Office 365 premium subscription."
"The tool's cost has been a little high, but I do not think it was terrible."
"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."
