Device control

ESET Security Ultimate provides automatic device (CD/DVD/USB/etc.) control. You can block or adjust extended filters/permissions and define a user's ability to access and work with a given device. This may be useful if the computer administrator wants to prevent using devices containing unsolicited content.

Supported external devices:

Disk Storage (HDD, USB removable disk)


USB Printer

FireWire Storage

Bluetooth Device

Smart card reader

Imaging Device


LPT/COM port

Portable Device (battery-powered devices such as media players, smartphones, plug-and-play devices, etc.)

All device types

Device control setup options can be modified in Advanced setup > Protections > Device control.

Click the Enable Device control toggle to enable the Device control feature in ESET Security Ultimate; you must restart your computer for this change to take effect. After enabling Device control, you can define the Rules in the Rules editor window.


You can create different groups of devices where different rules will be applied. You can also create only one group of devices for which the rule with action Allow or Write Block will be applied. This ensures blocking unrecognized devices by Device control when connected to your computer.

If a device blocked by an existing rule is inserted, a notification window will be displayed and access to the device will not be granted.
