The appointment followed a review. Zeno will need to make sure it maintains a clear firewall separating its accounts from sister shop Edelman, as Zeno's win comes just months after Edelman won Norton Antivirus, another major player in the category.
"We had a stellar lineup of agencies present, and while the decision was tough, we're really excited to have Zeno onboard," said a McAfee spokeswoman. It's not clear whether H3O Communications, which has worked with McAfee in the past, participated in the review. H3O didn't respond to a call for comment.
McAfee's spokeswoman declined to comment on what Zeno will be working on specifically. But looking at the company's portfolio of products, it's possible Zeno will be tasked with promoting the brand's digital products, such as its Facebook Social Protection app, which enables users to select which members have access to their profile pictures, according to various reports.
For Zeno, the account boosts a growing tech portfolio in its new Silicon Valley office. Since the office opened its doors in December 2011, it has won Micron and Brocade, among other bits of tech business.
Those wins, says Zeno, helped it report $16.6 million in revenue at the end of its fiscal year this June, representing a 27% growth increase over fiscal year 2011.
While the Silicon Valley operation remains a growth target for the firm, it's also focusing its efforts outside the U.S. In March, Zeno umbrella company Daniel J. Edelman mapped out a holding-company strategy that would expand its independent firms' operations through acquisitions. Vice Chairman Alan VanderMolen had said that one of the first orders of business would be to expand Zeno into global markets such as the U.K., Germany and China.
