Microsoft has rolled out a new feature in its Defender for Office 365 suite, designed to enhance how phishing attempts are handled. This feature, called the Advanced Agentic AI grading system, is like having a seasoned detective who can quickly and accurately assess whether an email is a phishing attempt.

Imagine you receive a suspicious email, and you’re unsure if it’s legitimate or a scam. Traditionally, you might forward it to your IT department, where someone would manually check it. This process can be slow and prone to human error. The new AI system works like a digital detective that can analyze these emails swiftly and provide a clear verdict.

Think of it as a highly skilled assistant who can explain its reasoning in plain language, making it easier for you to understand why an email is flagged as a threat. This is similar to having a mechanic who not only fixes your car but also explains what was wrong in terms you can understand, rather than using technical jargon.

This system is integrated into the existing Microsoft Defender for Office 365 workflow, meaning it fits seamlessly into the processes you already use. It’s like upgrading your office coffee machine to one that not only brews faster but also cleans itself, making your morning routine smoother without needing to change your habits.

Overall, this new feature aims to make the process of identifying and responding to phishing threats faster and more efficient, reducing the burden on IT staff and providing users with clear, understandable feedback.
