Kaspersky Endpoint Security lets you install trusted root certificates on user computers if, for example, you need to deploy a new certification center. The application lets you add a certificate to a special Kaspersky Endpoint Security certificate store. In this case, the certificate is considered trusted only for the Kaspersky Endpoint Security application. In other words, the user can gain access to a website with the new certificate in the browser. If another application tries to gain access to the website, you can get a connection error because of a certificate issue. To add to the system certificate store, you can use Active Directory group policies.
Open the Kaspersky Security Center Administration Console.
In the Managed devices folder in the Administration Console tree, open the folder with the name of the administration group to which the relevant client computers belong.
In the workspace, select the Policies tab.
Select the necessary policy and double-click to open the policy properties.
In the policy window, select General settings → Network settings.
In the Trusted root certificates block, click Add.
This opens a window; in that window, select a trusted root certificate.
Kaspersky Endpoint Security supports certificates with PEM, DER, and CRT extensions.
