Summary

Microsoft will integrate advanced AI models into its Security Development Lifecycle by April 2026 to identify vulnerabilities and provide mitigations. Customers should follow guidance via Microsoft Security Exposure Management to reduce exposure in key areas like patching and baseline security hygiene.

Details

Introduction

Microsoft is taking steps to help keep customers safe as AI models become more advanced including plans to incorporate advanced AI models directly into our Security Development Lifecycle (SDL) to identify vulnerabilities and develop mitigations and updates. We are also sharing guidance through Microsoft Security Exposure Management on how customers can reduce their exposure as well as capabilities they can use to take action. You can learn more in our blog here: https://aka.ms/prioritizingdefense 

When this will happen:

General Availability (Worldwide): We will begin rolling out on late April 2026 and expect to complete by late April 2026.

How this will affect your organization:

Customers should review the guidance and take action to reduce their exposure to the five dimensions where autonomous AI‑driven attacks gain disproportionate advantage - patching, open-source software, customer source code, internet-facing assets, and baseline security hygiene.  

What you need to do to prepare:

Customers can review the guidance in Microsoft Security Exposure Management at https://security.microsoft.com/securenow and use the capabilities provided to take action.
