Always scan the USB drive or external media on a secure, connected machine before plugging it into an air-gapped system.
No internet connection? No problem. Learn how to manually download and apply virus signature updates to ESET Smart Security for air-gapped PCs and unstable networks.
ESET Smart Security allows you to download the latest update package on an internet-connected machine and apply it manually to offline systems.
Ironically, the moment you connect to the internet to download an update, you are exposed. If a zero-day exploit targets the update mechanism itself, your system is vulnerable during the download window. With an offline update, you verify the file on a clean machine (or via a trusted physical medium) before deploying it to secure endpoints. eset smart security offline update better
Not every workstation operates in a zone with flawless, high-speed fiber internet. Remote research stations, maritime vessels, construction site trailers, and rural offices often suffer from spotty or non-existent connectivity.
Why Offline Updates for ESET Smart Security Are a Better Choice for Isolated Systems
If a local network experiences an extended internet outage, workstations remain vulnerable to local threats, such as infected USB drives brought in by employees. Having an offline update strategy ensures that your endpoint security remains fully updated even when the outside world is cut off.

Every computer in your office that runs ESET Smart Security pings ESET’s servers at random intervals. In an environment with 50+ workstations, this creates thousands of small, fragmented HTTP requests. While each request is small, the cumulative latency can choke a satellite internet connection or a metered LTE hotspot.
Automatic updates can occasionally introduce compatibility issues with niche, proprietary enterprise software. Offline deployment puts control back into the hands of system administrators.
