Opportunities**

Enhanced Data Security
Implementing Just-in-Time protection (JIT) allows for real-time application of DLP policies, significantly reducing the risk of data breaches from unclassified files. This proactive approach ensures that sensitive information is protected at the point of egress, enhancing overall data security.
   - next-steps: Conduct a risk assessment to identify critical unclassified files and develop tailored DLP policies for JIT protection. Train staff on the new protocols to ensure compliance and effectiveness.

Improved User Experience
By implementing JIT protection, users can access necessary files without hindrance while still adhering to compliance policies. This balance improves workflow efficiency as users are not obstructed by unnecessary restrictions during their tasks.
   - next-steps: Gather user feedback on current DLP processes and identify pain points. Develop a communication plan to inform users about the new JIT features and provide training sessions for smooth adoption.

Streamlined IT Operations
JIT protection automates the application of DLP policies at the time of file access, reducing the manual oversight required by IT teams. This leads to more efficient use of resources and minimizes the potential for human error in data protection.
   - next-steps: Review current IT workflows to identify areas where automation can be integrated. Train IT staff on the management of JIT policies and the tools available within Microsoft Purview.

explanation for non-techies**

Imagine you have a large library of books, and some of these books contain sensitive information that you don't want just anyone to read. Normally, you would have a system in place to classify these books, marking which ones are sensitive and need special handling. However, sometimes books come into the library without any classification, and you still need to ensure they are protected.

In the digital world, this is similar to managing files in SharePoint. Microsoft Purview's Data Loss Prevention (DLP) feature acts like a librarian who checks books as they leave the library. This "just-in-time" protection means that even if a file hasn't been classified yet, the system can still apply rules to it as it's being accessed or shared, ensuring sensitive information doesn't slip through the cracks.

Think of it like a security guard at the door who checks each book leaving the library, even if it doesn't have a special sticker indicating it's sensitive. This guard can apply the necessary restrictions to prevent unauthorized access or sharing, based on the rules you've set up.

For organizations, this means they can confidently manage their data, knowing that even unclassified files in SharePoint are protected at the moment they are accessed or shared. This approach helps prevent data loss and ensures compliance with company policies, much like how a library ensures its valuable books are only accessed by those with the right permissions.
