OS Signature (p0f)

ISP NEW supports the OS Signature (p0f) feature.

The feature changes TCP/IP connection characteristics that passive analysis systems may use to identify the presumed operating system. p0f does not change the User-Agent, TLS fingerprint, Canvas, WebGL, or other browser parameters.
