Datto EDR - Issues Accessing Certain Applications Following Recent EDR Update

Incident Report for Kaseya Inc

Monitoring

We’re pleased to inform you that our Engineering team has released a Hotfix for the Datto AMSI module remaining on devices:

UI 15272
Agent #3.17.1.5552

Fixes:
This release addresses an issue where the Datto AMSI provider remained actively registered on a device after having the AMSI module disabled.

The AMSI module remains disabled globally and will be reintroduced through a controlled rollout.

This change does not disable overall EDR protection. It is a temporary mitigation specific to the AMSI module.

The hotfix will be applied during your next scheduled maintenance window.
