Note: For organizational users, ESET PROTECT On-Prem can act as a repository and mirror server to facilitate this process automatically for multiple machines.
The software will read the local directory and update its detection modules immediately. Automating the Process via ESET PROTECT On-Premise
To perform an ESET offline update, you'll need to:
Ensure the USB drive used for transferring updates is scanned for malware on the online computer before being plugged into the air-gapped machine. eset offline update
If you are updating a standalone endpoint without using the Mirror Tool, you must first generate an offline license file (.lf) via the ESET Business Account (EBA) portal. Log in to your portal.
Once the update files are transferred to the removable media, the physical media is moved to the isolated (target) computer. The administrator then configures the ESET endpoint on the target machine to look for updates from a "Local Directory" rather than the internet. By browsing to the folder on the USB drive where the update files are stored, the ESET software treats the USB drive as a makeshift server. It verifies the digital signatures of the files and applies the updates, bringing the virus database current. This method ensures that even without a direct pipeline to the vendor, the endpoint retains its defensive capabilities.
Define the path where the files should be saved. Note: For organizational users, ESET PROTECT On-Prem can
Are you managing a or a large network of offline endpoints ?
There are two primary ways to handle offline updates depending on your infrastructure: using the (recommended for business environments) or using ESET PROTECT On-Premise . Method 1: Using the ESET Mirror Tool (Standalone)
Wait for the download to finish. The tool creates a folder structure containing the update files. Copy the entire output folder to your USB drive. Step 3: Configure the Offline ESET Endpoint If you are updating a standalone endpoint without
To download the necessary update files (the "source" machine).
To clean up old files and optimize a repository that has grown too large, use the parameter, which removes outdated files from the output folder.
In today's interconnected world, cybersecurity is paramount, but not all systems have the luxury of a constant internet connection. Industrial Control Systems (ICS), SCADA environments, high-security lab machines, and remote servers often operate on "air-gapped" networks—networks physically isolated from the internet to maximize security.
Updating ESET products without an internet connection generally falls into two scenarios: Standalone Method
Keeping antivirus software updated is a challenge for machines without internet access. Whether you manage a highly secure corporate network, private industrial equipment, or remote workstations, keeping your systems isolated—also known as an "air-gapped" environment—creates a unique cybersecurity dilemma.
