Rosch said he doesn't expect the acquisition will have much impact on the roadmap for Norton, which he said was already focused on solidifying the security business across a variety of different areas, including its traditional business, mobile, automated home, the Internet of Things, and, now, identity protection.

"We have a balanced strategy of things that we're trying to partner on some things and make acquisitions and do some cool innovation," Rosch said.

Rosch said Norton "doesn't have any plans to do any other acquisitions" for the time being. Symantec CEO Greg Clark has said that Symantec isn't done making acquisitions yet and will "continue to do the inorganic things that we've done for many years."

Clark said Symantec plans to build on the four pillars of information, users, web and messaging security in its enterprise security portfolio. Rosch said after the LifeLock acquisition, the enterprise security business "has no intention to do any other acquisitions at this point, but we do have flexibility for the future."
