ThreatDown, the former corporate business unit of Malwarebytes, today announced Chung Ip as Chief Financial Officer and Lisa O'Reilly as Vice President of Marketing. The hires support the company's channel-first growth strategy and focus on the mid-market and managed service provider (MSP) segments. The appointments follow significant momentum in the company's distribution-led go-to-market model.
ThreatDown appoints Chung Ip as CFO and Lisa O'Reilly as VP of Marketing to support channel-first growth.
Distribution grew from about 1% to 40% of revenue since adopting distribution-led go-to-market model.
Bundle adoption across Advance, Elite, and Ultimate tiers grew 14% in second half of 2025.
MSP customers increased add-on product usage by 12%.
Ip brings 20+ years of finance and technology leadership, most recently as CFO of Cleo.
O'Reilly brings B2B cybersecurity marketing expertise from iVerify, SlashNext, Proofpoint, and Dell.
“These appointments reflect where we are as a company,” said Kendra Krause, General Manager of ThreatDown. “We've built the partner model and proven the go-to-market strategy. Now we're investing in leadership to scale it. Chung brings the financial discipline to fuel growth, and Lisa brings the marketing leadership to help partners and customers understand the value ThreatDown delivers.”
Ip will lead finance for both ThreatDown and Malwarebytes, a global leader in real-time cyber protection, overseeing accounting, financial planning and analysis, investor relations, IT, legal, and the people team. He most recently served as CFO of Cleo, an AI led fintech company where he helped scale the organization from 90 to nearly 600 employees and navigated the business to profitability. Prior to Cleo, Ip spent 15 years in investing as a private equity and special situations investor at Accel-KKR and Outrider Management, bringing deep experience in corporate strategy and long-term value creation.
“What excites me about ThreatDown is the combination of proven technology and a go-to-market model that's clearly working,” said Ip. “The channel momentum is real, the customer base is expanding, and the opportunity in the mid-market is significant. My focus is on building the financial foundation to accelerate that growth and create lasting value for our partners and customers.”
O'Reilly joins ThreatDown with extensive experience scaling marketing operations for B2B cybersecurity companies. Most recently, she served as Vice President of Marketing at iVerify, where she led and managed all facets of marketing and corporate go-to-market strategy. Prior to iVerify, O'Reilly was Vice President of Marketing at SlashNext, where she helped grow the pipeline and revenue from 1Mto15M in ARR and supported the company's move from Series A to Series B funding and successful acquisition by Varonis. She previously held senior marketing roles at Proofpoint and served as Global Marketing Director at Dell.
“ThreatDown is uniquely positioned in the market, combining the legendary detection pedigree of Malwarebytes with a streamlined platform built for today's lean cybersecurity teams,” said O'Reilly. “I'm committed to leading this expansion, specifically by building programs that empower our partners and prove to mid-market organizations that world-class security doesn't have to be complex.”
