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.

Data lineage and quality checks have streamlined team-wide collaboration and business context
The biggest friction point or frustration I have encountered with Microsoft Purview Communication Compliance is cost-wise it is acceptable, but sometimes unexpected errors will occur, though this happens very rarely. There are features I wish Microsoft Purview Communication Compliance had that it does not provide today. Enterprise-level lineage is one such feature. As of now, if Microsoft were to provide this tool for free when you buy Microsoft Fabric, I feel that would be better. This would also result in lower license costs. I do not have any changes I would make to Microsoft Purview Communication Compliance at this time.

Quotes from Members

Pros

"Defender is top class in terms of functional security."
"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."
"Defender's main strength is its integration with Microsoft Sentinel, offering valuable insights."
"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."
"The solution is effective, continuously improving, and highly regarded, especially with Microsoft's leadership in the industry."
"The solution includes attack-savvy service and risk protection, part of data center management, and offers an effective single-dashboard view with Microsoft 365."
"It is scalable."
"I haven't had any problems with the tool's stability."
"Microsoft Purview Communication Compliance helps with extra collaboration and ensures communication is within the framework."
"The time it saves is very useful."
"Customer support is excellent."
"Microsoft Purview Communication Compliance has impacted my organization positively; it is a good tool that provides an end-to-end business view for a particular organization."
"The features I appreciate the most in Microsoft Purview Communication Compliance include the ability to build cases, give them dates, and find them based on the notes that I left behind."
 

Cons

"The security could always be improved."
"The tool's support is an area of concern where improvements are needed."
"The solution's AI is notorious for false positives, and the time you have to spend training it is ridiculous."
"I am not satisfied with Microsoft's technical support. There are challenges with the knowledge and experience of the support staff, frequent redirection between departments, and slow response times."
"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."
"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."
"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."
"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."
"Monitoring and compliance for web applications could be improved."
"The product should incorporate more automation with the help of AI."
"The biggest friction point or frustration I have encountered with Microsoft Purview Communication Compliance is cost-wise it is acceptable, but sometimes unexpected errors will occur, though this happens very rarely."
"Microsoft Purview Communication Compliance can be improved by having more tutorials available for those who aren't used to using this platform."
 

Pricing and Cost Advice

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