The feature I find most valuable that I'm currently using is the quickness of the emails that the Microsoft Purview Data Loss Prevention solution sends to us, where we get notifications that say a user has potentially breached our data guideline rules, and we get those alerts continuously, allowing us to enforce them manually.

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.

Nice dashboard, good data loss prevention, and helps with compliance

The data loss prevention is great. It can prevent things like credit card information from being taken. The data protection is excellent. We can use the solution on Windows and iOS. We mostly use it with Office 365 and ingest data sources from Microsoft. The solution is natively integrated and compliant across Azure. It takes into account critical regulations from around the world. We need to comply with various regulations. For our business case, it's very important. If we can prevent information from going out, eventually, when a regulator is asking about our security measures, we can show what we've been doing. It helps us to reduce the likelihood of potential fines. We can educate users on how to handle sensitive data. By showing the records we keep and explaining the technologies implemented, we can provide awareness to our users. The solution offers good visibility into our environment. Our security team can use the product to monitor and track. Its dashboard allows us to show compliance in real-time. We've been able to reduce the time to action on insider threats. Security permissions are always being monitored. In general, it has saved us time and money when dealing with security. It's made us become more efficient. We've increased our compliance capabilities by 25%.
