Broadcom has set its sights on acquiring a well-known name in cybersecurity software, in a further strategy shift after the Trump administration blocked it last year from purchasing another chip maker on national security grounds.

The semiconductor giant is in advanced discussions to buy Symantec, which makes antivirus software and other products, two people briefed on the matter said on Wednesday. Any deal would most likely value Symantec at more than $15 billion, they said. A transaction could be announced in the coming days, though the people warned that negotiations were still taking place and could fall apart.

A Symantec spokeswoman declined to comment, while a Broadcom representative did not immediately return a request for comment. The talks were earlier reported by Bloomberg News.

If an agreement is reached, it will underline how much Broadcom has had to change its acquisition strategy after the humbling defeat of its $117 billion bid last year to buy Qualcomm, the world’s largest maker of wireless chips. The Trump administration said it was specifically concerned that a deal for Qualcomm, an American company, would cede the nation’s primacy in the semiconductor and wireless industry and allow China to vault over the United States in next-generation wireless networks.
