Click

DiskLock Version 4.5 Now Protects Latest Mac OS

Minneapolis - August 16, 1999 -- Power On Software announced today the
immediate availability of a new release of "DiskLock" the world's number
one Macintosh security utility. Recently acquired from Symantec
Corporation, and formerly known as Norton DiskLock, the product has set the
standard for Macintosh data security for the past ten years and offers
users virtually unbeatable security with its one click file locking and
encryption.

DiskLock 4.5 provides support for the latest versions of the Mac OS,
including 8.6. This update, the first under the Power On brand, also
supports the iMac and the new G3 Blue and White Macintosh line. There is
also support for multiple users on the same Macintosh with different
security levels for each. In addition, SCSI and IDE drives, both fixed and
removable, are supported in the new version of DiskLock.

Ideal for protecting a user's privacy and data security, DiskLock protects
valuable and sensitive files and folders through sophisticated encryption
methods. What sets DiskLock apart from other products is its simple,
intuitive interface that allows a user to completely encrypt data by simply
pointing and clicking.

DiskLock's protection is not only industrial strength, but it is a breeze
to use as well. Set-up is much faster than with other security programs.
Instead of having to select each file, users can choose entire folders with
a single click or, if preferred, encryption and decryption can be
accomplished through DiskLock's drag and drop support. DiskLock is
virtually impossible to bypass -- it loads before the system software, so
unauthorized users can't start up a system, even from a floppy disk or
System CD.. DiskLock also supports multiple users, each with his or her own
password and levels of access.

Not only does DiskLock protect files from prying eyes, but it also guards
against fumbling fingers to insure against accidental deletion of protected
files.

Other features include:

Hot key screen-locking allows users to instantly blank the screen from
within any application

Idle-time screen blanker automatically blanks the screen and locks the
system after a specified amount of time for privacy protection when a user
step away from the computer, while other tasks, such as printing or fax
processing, continue uninterrupted in the background. Includes a built-in
screen saver and supports third-party screen savers

Audit management that logs invalid access attempts and locking and
unlocking of files and folders

Power On has extensive experience in security software. Power On's access
configuration product, "On Guard" for Macintosh, has over 1 million users
and has recently been licensed by Kinko's to protect all its machines in
North America. "By adding DiskLock to our offerings, we now provide the
most extensive set of security options on the Macintosh," said John
Wallace, president of Power On Software. "We recognize the growing
importance of data security to our customers and are delighted to be able
to add the extra levels of security that DiskLock provides."

The suggested retail price of DiskLock is $129.95. Upgrades to the new
version, DiskLock 4.5 will cost $49.95 and site license pricing is
available. DiskLock is sold through dealers, mail order catalogs, and
electronically and is available now.
