Yes, but it is not recommended for home users. You need to manually download the ZIP file and change the update profile. It is much easier to use a mobile hotspot for 60 seconds than to perform an offline update for a home PC.
While offline updates solve a connectivity problem, they introduce logistical challenges. The most significant is the "update latency." A computer connected to the internet can receive signature updates every hour; an offline computer relies on a human administrator to perform the transfer. If the administrator waits a week between offline updates, the system is vulnerable to any zero-day threats discovered during that window.
Note: You must have a valid ESET license to generate an offline license file in the ESET Business Account (EBA) portal. Phase 2: Downloading the Offline Update Files eset offline update
Once configured, your ESET product on the offline network will check this local mirror for updates, bypassing the need for an internet connection entirely.
In today's cybersecurity landscape, the "air-gapped" computer—a machine entirely disconnected from the internet—is often deemed the most secure. However, this same lack of connectivity creates a significant vulnerability: the inability to receive automatic signature updates, leaving the system exposed to new threats.
