Microsoft Technical Security Notifications

Help protect your computing environment by keeping up to date on Microsoft technical security notifications.

Security Update Email Alerts

Microsoft's free monthly Security Notification Service provides links to security-related software updates and notification of re-released security updates. You can choose between basic and comprehensive formats.These notifications are written for IT professionals, contain in-depth technical information, and are digitally-signed with PGP.

Security Advisories Alerts

Microsoft Security Advisories are a way for Microsoft to communicate security information to customers about issues that may not be classified as vulnerabilities and may not require a security bulletin. Each advisory will be accompanied with a unique Microsoft Knowledge Base Article number for reference to provide additional information about the changes.

Microsoft Security Response Center Blog Alerts

The Microsoft Security Response Center (MSRC) blog provides a real-time way for the MSRC to communicate with customers. You can also follow us on our Twitter feed @msftsecresponse.

Verifying Our Digital Signature

Pretty Good Privacy (PGP) is an Internet standard for digitally signing and encrypting e-mail and other documents. The Microsoft Security Response Center (MSRC) uses PGP to digitally sign all security notifications. However, it is not required to read security notifications, read security update information, or install security updates. You can obtain the MSRC public PGP key at the MSRC Security Notification PGP Web page. Numerous third-party vendors produce PGP-compatible applications for a variety of platforms, but Microsoft cannot recommend the right solution for your environment.
