What’s SISIPSService.exe (Symantec IPS Service)? Is it safe or a virus?

SISIPSService.exe is a core component of Symantec Endpoint Protection (SEP), developed by Symantec Corporation. This executable is part of the Intrusion Prevention System (IPS) within SEP, responsible for monitoring network traffic and system activities to detect and prevent potential security threats.

It operates as a background service, continuously analyzing data to identify suspicious patterns that may indicate malicious activity. This process is typically active on systems where SEP is installed, especially in enterprise environments that require robust security measures. ​

What does it mean if someone is the publisher of a PC .exe (executable or process)?

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
