UPDATE: The Capricorn release was delayed until 11.5.2023 so we could further validate it, to ensure a smoother update for our customers. Updates containing this release start with "Capricorn Engine (2023-05-11_04)", although do note that machines that are powered off may skip this update and take a later one. Later revisions also contain the updated content. The name of the update will vary slightly depending on your installed product.
On May 10th 2023, WithSecure plans to release a substantial database update for the Capricorn engine. The expected size of this incremental update will be approximately 34MB. This is larger than the normal updates.
The update is anticipated to be released at approximately 8.00 UTC.
This update will contain revamped signatures and models which are expected to minimize the database file sizes afterwards and bring better performance.
With the default product settings, this update will happen automatically. This will affect WithSecure's Windows, Mac and Linux EPP products.
Users of WithSecure Elements EPP may wish to consider taking the Elements Connector into use, to help reduce internet access, if they have several deployed endpoints. You can find more details of how to deploy this at
