Caching of downloads and updates

ESET Bridge downloads and caches:

ESET module updates

Installation packages and update packages pushed by ESET PROTECT (for example, ESET Endpoint Security MSI installer)

ESET security product updates (component and product updates)

ESET LiveGuard Advanced results

ESET Bridge distributes the cached data to endpoint clients on your network. Caching can significantly decrease internet traffic on your network.


Use the Mirror Tool (available for Windows and Linux) for offline detection engine updates instead of ESET Bridge.

In contrast to the Mirror Tool, which downloads all available data on the ESET update servers, ESET Bridge reduces the network load by only downloading the data requested by ESET PROTECT components or ESET endpoint products. If an endpoint client requests an update, ESET Bridge downloads it from the ESET update servers, saves the update to its cache directory and then serves it to the individual endpoint client. If another endpoint client requests the same update, ESET Bridge sends the download to the client directly from its cache, so there is no additional download from ESET update servers.

The following diagram illustrates ESET Bridge as a proxy server distributing updates to all ESET PROTECT components and ESET endpoint products.


Caching for ESET security product

Caching settings of ESET Management Agent and Endpoint are not identical. ESET Management Agent can manage settings for ESET security products on client devices.

You can set up a proxy for ESET Endpoint Security in two ways:

Use an ESET security product Policy from ESET PROTECT Web Console—we recommend this option to manage client device settings.

Locally from the ESET Endpoint Security main program window.

Caching ESET LiveGuard Advanced results

ESET Bridge can also cache results provided by ESET LiveGuard Advanced. ESET Bridge is pre-configured to cache ESET LiveGuard Advanced (no manual configuration changes are needed). We recommend using caching with ESET LiveGuard Advanced. See ESET LiveGuard Advanced documentation for more details.
