Sometimes the solution is not stable when the internal connection is not reliable, so this aspect needs improvement.
 

Room For Improvement

Microsoft Defender for Identity requires enhancements in cloud security, SIEM integration, and user access controls, facing various operational challenges.
Microsoft Purview's Data Loss Prevention needs improved labeling, integration, language support, incident handling, and Power Automate functionality.
One improvement I would recommend is the integration of an admin application within Teams, allowing easy access to attack information on a mobile platform.
Reducing false positives is something we've been working on with Microsoft.
There is room for improvement in delivering knowledge to technical users, especially regarding what we can gain from the solution and how to apply it.
Endpoint Data Loss Prevention needs to be improved as it is not up to expectations.

Easily detects advanced attacks based on user behavior
The best feature is security monitoring, which detects and investigates suspicious user activities. It can easily detect advanced attacks based on the behavior. The credentials are securely stored, so it reduces the risk of compromise. It will monitor user behavior based on artificial intelligence to protect the identities in your organization. It will even help secure the on-premise Active Directory. It syncs from the cloud to on-premise, and on-premise modifications will be reflected in the cloud. Identity harvesting is the most common threat. Legacy Microsoft solutions and Amazon face the same issues in the cloud. Users don't implement other security mechanisms in the cloud. In an on-premise environment, we would have multiple security devices like firewalls and several layers of security. Cloud users are less bothered because cloud features are there and only need to be configured. Microsoft Defender for Cloud is the best solution because all threats are completely visible, and it has a great dashboard. The dashboard displays each threat and score, so we can identify the threat rating and act efficiently to avoid compromising user identities. We have a single sign-on feature on the cloud. If we lose a single set of identities, it can compromise the entire organization, including cloud and on-premise. The same identities are being used everywhere. The user activity has to be completely visible on the dashboard, and it has to generate a pattern. It will notify us if there is any security breach. It is a complete monitoring set. Minor changes in the user identity can lead to data leakage. If a password is changed in the cloud, it will be reflected automatically in the on-premise. This minor change will trigger an alert in Microsoft Defender for Identity. It ensures that each cloud identity is well protected from spoofing. It has a comprehensive database of well-known spoofing techniques, enabling us to provide cloud identity protection completely. It has a vast scope because it is completely single sign-on. In the emerging industry, we use single sign-on because users need to authenticate, but it's challenging to remember multiple passwords. Once your user signs in, you can access all the data. An identity compromise would lead to various issues and affect the data on-premises. Defender maintains a constantly updated database with the latest signatures, attack models, and threats. If it detects one threat, it will monitor the suspicious event and give us frequent alerts. Identity protection is vital because we use an identity mechanism for everything, including firewall-related activities. The exact identity used in the cloud is used in the most complex firewalls. We require an excellent migration technique to regain this user credential if something gets compromised. Blocking this requires a massive set of procedures. Microsoft Defender comprehensively monitors identity and provides frequent alerts regarding any issue, so we don't need to think of anything else. Defender's bidirectional sync capabilities are helpful because we need to sync data from multiple directions, including tenant-to-tenant, on-premise-to-cloud, and cloud-to-cloud syncing. As a university, we have multiple tenants, so we need to sync or access data across platforms. That way, everything is more secure, and Microsoft Defender for Cloud also provides ample security for cloud transfers. The bidirectional sync capabilities are flawless—10 out of 10. Our on-premise Active Directory is perfectly synced with the Azure AD. Everything is synced with on-premise, and changes are reflected in minutes. If a problem with identity is addressed on the cloud, the fix will be mirrored on-premise and vice versa. Microsoft Defender for Cloud and Identity are bundled. If we have these two solutions, we don't need to worry about anything else or third-party antivirus. Microsoft Defender for Identity acts as a link to all the Microsoft security features that require identity-based validation. Microsoft Defender instantly provides identity security for all our applications, and users need not worry about typing their passwords. Even in situations with less complex encryption mechanisms, users don't need to worry about typing in their passwords. Defender will check and monitor if there are any flaws in that, and it will let us know if there are any issues. We're a Microsoft shop, so everything works together. If one feature isn't working, everything will be affected. If Defender isn't working, half of our Microsoft security features will be dead. Without identity security, user data can easily be compromised, and data can fall into the hands of intruders or other hackers. The solutions have to complement each other. If anything got wrong, the entire setup would have flaws. Microsoft security has a legacy security mechanism. A while back, we might have gone with Defender for Endpoint, but Microsoft has also grown into the face of the cloud. The same Defender solution is completely maintaining cloud security. We can imagine Microsoft's vast scale and how Defender can protect the cloud environment from vulnerabilities and attacks. We are definitely delighted with Microsoft products. The dashboard features are fantastic because it provides a comprehensive overview. It has a great alert mechanism and log inspector that tracks when users access various servers. With this kind of identity validation, we can control which servers the users can access. We have total visibility from the dashboard. We can track identity usage even if there are no issues. That is an essential advantage.

Automation has given us consistent analytics and improved quality of insights into user activity
One of the valuable features of Purview is the ability to create a legal hold on a user's account within the compliance portal. That's pretty useful when it comes to any litigation or if you want to redeem the content within a mailbox, OneDrive, or a generic public SharePoint site. If you want to retain the user's data until the case is resolved, you can use the legal hold feature. Also, it's important that Purview can connect to iOS, Mac, and Android devices. With smartphone involvement, so many applications can now be accessed through them and it is important to apply Purview across operating systems and platforms. Purview's natively integrated compliance across Azure Dynamics and Office 365 is also significant because within Microsoft 365 there are multiple applications. Irrespective of whether it's Dynamics or Azure, it's very important that it has native support. The data connectivity should be efficient enough to support and secure their own platform's data. In addition, with varying regulations in different industries and matters, Purview lets you create rules and conditions based on industry standards around the world. That is important. Our company is in pharmaceuticals and the rules and conditions are different from other industries. It is important to be able to keep track of all these regulations and have a tool that is flexible enough to create the regulatory rules and conditions we need. And when it comes to data loss protection, Purview has features that can recognize patterns and detect any sort of data loss, where the data is being transferred from its platform to a different one. The default settings that come with it are pretty nice for identifying data transfer or data loss across the platform. It also comes with a lot of training materials, with use cases and examples, to help educate users and make them familiar with the tool.
