IT managers have been among BlackBerry's most loyal customers because of the data security in the phones
Samsung has introduced a new software - Knox - which helps to protect users from malware.
With the new software, Samsung hopes to make its smartphones attractive to corporate information technology departments that worry about the theft of sensitive corporate data by hackers.
IT managers have been among BlackBerry's most loyal customers because of the security BlackBerry has built into its phones and the private communications network it maintains.
Samsung said it teamed up with General Dynamics, a military contractor, to ensure its phones met the strict security standards of government agencies.
Samsung executives have said Knox will first appear on a new Galaxy smartphone in the second quarter. That phone is likely to be the Galaxy S IV, which is expected to be introduced at an event in New York on March 14.
