A top executive at Ripple has left the fast-growing cryptocurrency giant to join a blockchain start-up.

Harbor, which is transforming private securities with blockchain technology, has appointed Sujay Jaladi as chief information security officer.

The former head of information security at Ripple will oversee Harbor's comprehensive information security strategy and programmes.

"Sujay has the perfect blend of fintech and blockchain experience to accelerate our efforts to build a trusted platform for issuers, investors and regulators," said Harbor's co-founder and CTO Bob Remeika.

"Harbor is bringing traditional finance to blockchain, which requires institutional-grade systems, processes and procedures. Sujay’s experience building institutional-grade programs will be invaluable to ensuring the safety of customer data and complying with regulatory requirements."

Jaladi is a cybersecurity strategist with more than a decade in senior roles at leading companies, including Ripple, Gusto, Prosper Marketplace, Xoom Corporation (a PayPal service) and Hightail.

Most recently at Ripple, he was responsible for all aspects of security and managing risk across the company. His experience includes working in high-transaction environments where millions of transactions are processed every hour and performance is extremely critical.

Jaladi added: "I've followed Harbor's progress for some time and am excited to help deliver a highly secure service that issuers and investors can rely on to make critical financial transactions.

"The mission to reengineer private securities is an exciting opportunity and Harbor is well positioned to lead."
