Crittora, a security technology company developing cryptographic authority solutions for AI agents, announced on June 23, 2026, the appointment of John Darke as Vice President of Sales. Darke is tasked with scaling the adoption of the company's security technologies, which are designed to verify permissions, protect sensitive data, and provide verifiable proof before AI agents perform high-risk digital actions in sectors such as finance and banking.

In his new role, Darke will lead Crittora’s sales strategy, accelerate revenue growth, and expand strategic partnerships to bring the firm's security offerings to a broader enterprise market. Crittora’s technology aims to address the security challenge of establishing trust when autonomous AI agents, applications, or systems execute consequential digital actions rather than merely processing information. The system is designed to verify permissions and encrypt transactions before access is granted to APIs or tools.

Darke brings over 20 years of experience in cybersecurity, cloud, and enterprise technology to Crittora. He previously served as Senior Director of Sales at Keeper Security, where he focused on enterprise password and privileged access management. Before his tenure at Keeper Security, Darke spent 19 years at HPE Aruba Networking. During that period, he was responsible for driving more than 500% revenue growth through regional expansion and territory development. He also played a key role in achieving over 250% growth in SD-WAN and Secure Access Service Edge solutions, helping organizations adopt zero-trust security architectures to modernize networking.
