Microsoft Sentinel's ability to correlate data from multiple sources and its detection capabilities are essential.

HosmanRodriguez - PeerSpot reviewer
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%.
