Hazeltree and Walrus Security Announce Strategic Partnership to Strengthen Secure Payment Operations for Alternative Investment Firms

NEW YORK and LONDON — 16 June 2026 — Hazeltree, a provider of cloud-based treasury and liquidity management solutions for investment management firms, and Walrus Security, the company behind the DoubleCheck® payment authentication platform, today announced a strategic partnership designed to help alternative investment firms strengthen payment security, reduce operational friction, and improve confidence in payment workflows.

By bringing together Hazeltree’s treasury, liquidity, and portfolio finance capabilities with Walrus Security’s payment authentication technology, the partnership aims to support firms seeking more secure and efficient processes for collecting and validating payment instructions. The combined value proposition is expected to be especially relevant for hedge funds, private markets firms, fund administrators, and other organizations managing complex payment operations.

“Our clients are focused on maximizing control, increasing transparency, and reducing risk across treasury operations,” said Douglas Trafelet, Chief Commercial Officer at Hazeltree. “Partnering with Walrus Security extends that mission into one of the most critical operational areas for investment firms: the secure collection and authentication of payment instructions. Together, we can help clients modernize workflows while adding an important layer of protection against payment fraud.”

“Payment instruction fraud remains a serious challenge for organizations handling high-value transactions,” said Michael Walfish, Walrus Security Founder. “By partnering with Hazeltree, we have an opportunity to bring stronger authentication and greater assurance into the operational workflows of sophisticated investment firms. We believe this collaboration will make it easier for clients to protect payments without adding unnecessary friction.”

The partnership will create new opportunities for clients to improve control frameworks around payments, support operational resilience, and advance best practices in treasury and finance operations.
