NEW YORK, Feb 21 (Reuters) - AT&T Inc (T.N), the second-biggest U.S. wireless carrier, is exploring a sale of its cybersecurity division, potentially undoing an acquisition it completed five years ago, according to people familiar with the matter.
The sale of the cybersecurity business would add to a string of divestments AT&T has turned to in order to pay down debt following its $108.7 billion acquisition of Time Warner Inc in 2018, a deal it has since also unwound.
AT&T has been working with Barclays Plc (BARC.L) to solicit potential bids for its cybersecurity business, which was called Alienvault when it was acquired in 2018 in a roughly $600 million deal, the sources said.
The sources cautioned that no deal is certain and requested anonymity because the matter is confidential.
AT&T's cybersecurity division helps small-to-medium-sized businesses keep their information technology networks, including laptops, desktops, servers and mobile devices, secure.
