Each month, OneNeck engineers review newly released updates from vendors, like Microsoft, to understand any known issues, actions required and understand the priority of each. This is done immediately following Patch Tuesday releases, and we monitor for adjustments to patches throughout each month.

The information above is gathered monthly during this review and posted for awareness to our customers. This information is generally updated only once per month and is based on our engineers’ review of the information provided by the vendor at that time. As always, for the most up-to-date patching information, please see the vendor’s website or contact us.

Note: If OneNeck actively manages a device or software that is impacted by any of these vulnerabilities, when necessary, OneNeck will be in direct contact with you regarding remediation.
