Has delivered automated threat response and streamlined integration with advanced tools
The best features of Microsoft Defender for Business include it coming as an XDR solution which provides automated investigations, remediations, and endpoint detection and response. Moreover, it can be tightly integrated with vulnerability management or detecting vulnerabilities and pushing them to the SIEM solution. I utilize the advanced threat hunting feature of Microsoft Defender for Business and find it helpful; it's good and improving with every update. Microsoft Defender for Business integrates effectively with the Microsoft ecosystem as with Azure Sentinel, and it has a two-way natural integration. Apart from that, it also integrates with industry SIEM solutions such as Splunk.

Automated retention has transformed compliance workflows and now simplifies audit responses
The deep native integration with Microsoft 365 is what ultimately made me decide on Microsoft Purview Data Lifecycle Management over Enterprise Vault and OpenText Content Manager. Auto-apply retention labels using machine learning is the specific integration with Microsoft 365 that made it the deciding factor for me over Enterprise Vault or OpenText. Manually labeling content at our data volumes is not realistic. The automated classification based on sensitive information types and trainable classifiers is what makes the program actually scale. That feature gets used constantly. We went from inconsistent ad-hoc retention practices to a consistent, automated, documented program across the whole organization with Microsoft Purview Data Lifecycle Management. That shift from a compliance audit perspective is enormous.

Quotes from Members

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

Pros

"A few things are valuable. One is the alerting we see when any kind of intrusion is happening, any kind of malware is being deployed across the endpoints, or any kind of suspicious activity is going on. We have a footprint across all of North America, Canada, and Mexico, so we want to make sure that all our endpoints are protected and we are able to look for any anomalous activity."
"Microsoft Defender for Business works well with the Microsoft Azure Security ecosystem, including Defender for Endpoint and Office 365 Cloud."
"I rate Microsoft Defender for Business a 10 out of 10."
"Defender is top class in terms of functional security."
"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 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."
"If you're an Intune user, you can bring in certain capabilities like system-hardening policies, which further enhances the security."
"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."
"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."
"We went from inconsistent ad-hoc retention practices to a consistent, automated, documented program across the whole organization with Microsoft Purview Data Lifecycle Management."
"The UI is the most valuable feature."
"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 system is stable; I haven't encountered any worldwide stability issues unlike other office products."
 

Cons

"Defender's reporting is rather scattered, and its URL filtering mechanism doesn't really work."
"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 solution's AI is notorious for false positives, and the time you have to spend training it is ridiculous."
"I have an open case for close to two months with no responses or updates, except for an email response, and I've made four or five phone calls regarding the Microsoft Interconnect for AD and cloud tenant."
"Additionally, the pricing policy poses a challenge, particularly in multi-year contracts, where other solutions like Trend Micro offer more affordable options."
"We face a licensing issue with Windows 11 Enterprise not reflecting in our portal, which affects activation. Microsoft's support did not resolve this issue, even after sharing remote desktop and screen details."
"The threat detection capabilities require significant customization for multistage threat detection."
"The technical support from Microsoft is very poor. I would rate it a one, as their technical staff are very junior and take a long time to respond to simple questions."
"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."
"The initial setup took longer than we expected. Microsoft Purview Data Lifecycle Management is not a turn-it-on-and-go product."
"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."
"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's cost has been a little high, but I do not think it was terrible."
"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."
"Since we're a nonprofit, we get pretty good discounts on the tool."
"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 service operates on a pay-as-you-go basis, charging an extra one cent per field of metadata scanned in our data."
