MAPP Partners with Updated Protections

Microsoft offers information about additional protections provided by the security software providers enrolled in Microsoft Active Protections Program (MAPP).

The MAPP partners listed below have updated their software protections for the issues discussed in the respective Microsoft Security Advisory. Some of these partners have released protections and notified Microsoft within 48 hours of advisory release while others have released protections and notified Microsoft from 48 to 96 hours after advisory release.

This page does not identify MAPP partners who may have released protections more than 96 hours after advisory release or other protection providers who are not MAPP partners but who may have also released protection. If your protection provider is not listed, please contact your protection provider directly to inquire about protection for an issue.

Microsoft recommends customers keep their systems’ protections updated. For more information about protections released by MAPP partners, please contact the security software provider directly.
