rating 69, window not visible. Using at a 'net cafe--part of local monitoring or something more nefarious?
Used as part of Centurion DriveShield - protects hard drives from changes
I know that its running constantly on my school network, and they are probably spying on you/us
Part of Drive Shield, used to lock workstations so that permanent changes can not be made

It is a program that allows you to lock the computer hard drive against changes on a public access computer

CTI Driveshield file for communicating data across network... program associated with maintaining image of drive - not allowing any change to drive on remote computer

Harmless. Simply used by DriveShield utility to communicate with Network Control Manager
Their software protects the HD by dumping ALL your session activity into "Scratch Space" which is promptly cleared on reboot, as well as restoring an image from a remote machine, returning the computer to it's original state regardless of any "Nefarious activity". It can stump the average savvy computer user, but not always.

CenturionGuard® uses a lock and key or/and software to enable and disable security protection

It is easly over ridden and detected. If they want to have a successful software than they need to concentrate on hiding it from advanced computer experts.
Used for Drive Sheild. It keeps the hard drive from having changes applied to it.

Best practices for resolving CTIServ issues

A clean and tidy computer is the key requirement for avoiding problems with CTIServ. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the CTIServ.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
