In its third executive appointment of 2026, Finite State, a specialist in product security and software supply chain risk management, has named Ann Miller as vice president of marketing.

Miller brings more than 15 years of experience scaling high-growth technology companies, with expertise in cyber security and AI-driven platforms, and is known for turning emerging technologies into market-defining categories.

Miller joins Finite State at a pivotal moment as enterprises face increasing pressure to secure software embedded across critical infrastructure, regulated envronments and connected devices such as connected cars, medical devices, routers, IoT, IIoT and consumer electronics. Her appointment underscores the company’s commitment to defining the future of product security through data, automation and AI.

“Product security is quickly becoming one of the most critical and under-addressed challenges in cyber security,” said Miller. “What impressed me about Finite State is what they’ve built. It’s an AI-native platform that automates product security end to end, from deep binary analysis through prioritisation and remediation across the software supply chain. That’s incredibly hard to do, and has been a key driver in building trust across their customer base.”

Miller will lead all aspects of marketing, including branding, demand generation, product marketing and go-to-market strategy.

“Ann has a proven track record of building category-defining marketing engines in cyber security,” said Matt Wyckhouse, CEO of Finite State (finitestate.io). “Her ability to translate complex, technical innovation into market leadership will be instrumental as we accelerate our growth and expand our position in product security.”

Prior to joining Finite State, Miller led marketing at Horizon3.ai, where she helped scale the company from early stage to thousands of customers, driving rapid market adoption. During her tenure, Horizon3.ai was recognised as the fastest-growing cyber-security company on the 2025 Inc 5000 list and established leadership in autonomous security testing. Earlier in her career, she held roles at Cylance, a pioneer in AI-driven endpoint security, and cloud security firm Iboss.

Her appointment follows the February 2026 appointment of Sharon Hagi as chief security officer and January 2026 appointment of Chris Overton as executive vice president of engineering.
