MS-DEFCON 4: Mixed bag for March
ISSUE 22.12.1 • 2025-03-25 By Susan Bradley
Although CISA has given businesses who follow its guidance until early April to install updates released in March, I’m urging you to do so now.

Note that my recommendations for businesses include some possible exceptions.
Anyone can read the full MS-DEFCON Alert (22.12.1, 2025-03-25).
