NEW YORK, Feb 11 (Reuters) - IronNet Cybersecurity Inc, a startup led by former U.S. National Security Agency chief Keith Alexander, has appointed William Welch as co-chief executive, the company told Reuters on Monday.
Welch, former chief operating officer of Duo Security, a venture capital-backed cybersecurity company that was sold to Cisco Systems Inc for $2.35 billion last year, will serve as co-CEO along with Alexander, who ran the NSA from 2005 to 2014, the company said.
Prior to Duo Security, Welch was COO of cybersecurity firm Zscaler Inc, which went public in 2018.
IronNet, a provider of cyberdefense products, has raised over $110 million in two rounds of financing since it was founded in 2014. Investors include ForgePoint Capital, Kleiner Perkins Caufield & Byers and London-based C5 Capital.
The company declined to disclose its valuation.
IronNet also said on Monday the customer base of its threat-sharing technology dubbed IronDome has expanded since its launch in 2017 to include companies in the financial services, energy, healthcare and telecommunication sectors.
The company declined to name the companies, citing customer confidentiality. (Reporting by Angela Moon; Editing by Steve Orlofsky)
