Tidal Cyber Appoints Ann Chesbrough as Head of Product Marketing to Drive Growth and Category Leadership
ARLINGTON, VA – August 14, 2025 – Tidal Cyber, the global leader in defensive security and pioneer of Threat-Led Defense, today announced the appointment of Ann Chesbrough as Head of Product Marketing. A proven go-to-market leader with deep cybersecurity expertise, Chesbrough has launched more than 14 products throughout her career on both the provider and customer side, delivering measurable impact through product strategy, positioning, messaging, and partner collaboration that fuels adoption and growth.
Chesbrough most recently served as Vice President at BreachLock, a global leader in offensive security, where she played an integral role in launching their product portfolio and helping to drive pipeline growth. Her leadership played a key role across the organization and supported a period of rapid company expansion.

Today, SafeBreach is a key technology partner of Tidal Cyber, helping validate defensive controls through continuous adversarial testing.

“Tidal Cyber is building something truly transformative, and I’m excited to be part of a team that is reimagining what it means to defend against real threats and adversary behavior,” said Chesbrough. “I joined Tidal Cyber because of its mission, people, and product and I look forward to helping shape a category that moves our industry forward.”
“Ann’s product marketing expertise and leadership are exactly what we’ve been looking for,” said Rick Gordon, CEO and Co-Founder of Tidal Cyber. “Her track record of successful product launches and her deep understanding of how to partner with technology providers to drive value makes her an ideal fit to lead our go-to-market efforts. We’re thrilled to welcome her to the Tidal Cyber team.”
