Copy the ESET_Mirror folder to your USB drive and move it to the offline computer.

ESET offline updates allow computers in closed environments or with restricted internet access to maintain protection by downloading module and application updates from a local "mirror" rather than directly from ESET servers. This process typically involves a machine with internet access using the to create a repository of updates, which is then served to offline clients via an internal HTTP server or a shared network folder.

Setting Up an Update Mirror (Advanced)

Instead of each endpoint downloading files individually from the internet, a designated administrator downloads the necessary update packages from a machine with internet access. These files are then securely transferred to the isolated network using physical media (like a USB drive) or a local intranet share. Why Use Offline Updates?

ESET supports two primary approaches for implementing offline updates. The right choice depends entirely on your infrastructure.

Create a folder named MirrorTool and extract the downloaded file into it. Open your command prompt (cmd) as an administrator, navigate to the folder, and run the command to download the update files. A standard Windows command structure looks like this:

While highly effective for security, this method does present distinct operational challenges. The most significant drawback is the administrative overhead, as it requires manual intervention every time an update is needed. Because modern cyber threats evolve rapidly, sometimes hourly, infrequent manual updates can leave isolated systems temporarily vulnerable to brand-new malware strains. Consequently, administrators must establish strict, frequent routines for transferring these files to maintain an acceptable security posture.
