What is the disadvantage of automatic remediation?

The disadvantage of automatic remediation is that it can make a disruptive change to a user, block access to an application, or disconnect critical systems from the network. Automatic remediation can have unintended consequences if not carefully planned and tested. Therefore, it is recommended to use manual or semi-automatic remediation for sensitive or critical systems.
