Crittora, a security technology company developing cryptographic authority solutions that govern AI agents and high-risk digital actions, today announced the appointment of John Darke as Vice President of Sales.
Darke joins Crittora as organizations look for safer ways to adopt AI-driven workflows, protect sensitive data, and establish trust before digital actions are executed.

“Crittora is addressing one of the most important security challenges emerging in the market: how to establish authority and trust when AI agents, applications, and systems are no longer just processing information, but taking action,” said John Darke, Vice President of Sales at Crittora. “Companies need security solutions that can verify permission, protect sensitive data, and provide proof before high-risk digital actions occur. I’m excited to help scale Crittora’s customer relationships, partnerships, and revenue as the company brings this technology to market.”
Crittora’s technologies are designed to verify permission, encrypt transactions, and produce verifiable proof before an AI agent, application, or person is allowed to access data, call an API, use a tool, exchange sensitive information, or change a system. As enterprise adoption of AI accelerates, Crittora helps organizations innovate with confidence by securing how authority is granted, how data moves, and how digital actions are verified.
