Vulnerability risk
The Meltdown and Spectre attacks are not a remote compromise against the Forcepoint DLP and Web Security Endpoints. These vulnerabilities have no direct impact on the Forcepoint DLP and Web Security Endpoints and very little indirect impact.
The Meltdown vulnerability allows a local user with normal user privileges to read kernel memory via a specially crafted exploit program. The Forcepoint DLP and Web Security Endpoints are not general-purpose systems and only trusted administrators should have local user accounts.


Forcepoint DLP and Web Security Endpoints are fully compatible with the following updates provided by operating system and browser vendors.

Windows (including Internet Explorer and Edge browsers) - See https://support.microsoft.com/en-us/help/4073757/protect-your-windows-devices-against-spectre-meltdown.
