Crittora names John Darke as sales chief to push AI-agent security

Crittora has appointed veteran cybersecurity executive John Darke as vice president of sales as the company works to expand adoption of its cryptographic authority tools for AI agents and high-risk digital actions. The move comes as enterprises look for stronger permission checks, proof, and data protection before AI systems act in finance, banking, and other sensitive workflows.

Why it matters: - Crittora is trying to position its security stack as a control layer for AI agents that can take action, not just process data. - The hire signals a push to sell more broadly into enterprise accounts that need permission checks, auditability, and protection for sensitive transactions. - The company is targeting use cases where AI-driven actions can create financial, operational, or compliance risk.

What happened: - Crittora announced the appointment of John Darke as vice president of sales. - Darke will lead sales strategy, accelerate revenue growth, expand strategic partnerships, and help bring Crittora’s cryptographic authority technologies to a wider enterprise market. - Crittora framed the hire as part of a broader effort to scale secure AI-agent adoption. - The announcement was made June 23, 2026.

The details: - Darke joins Crittora after more than 20 years in cybersecurity, networking, cloud, and enterprise technology sales. - Most recently, he was senior director of sales at Keeper Security. - At Keeper Security, Darke worked on enterprise password management, privileged access management, and zero-trust security solutions. - Before that, Darke spent 19 years at HPE Aruba Networking in sales leadership and management roles. - Crittora said Darke helped drive more than 500% revenue growth through new territory development and regional expansion. - Crittora also said Darke helped drive more than 250% growth in SD-WAN and Secure Access Service Edge solutions. - Crittora’s technologies are designed to verify permission, encrypt transactions, and produce verifiable proof before an AI agent, application, or person can access data, call an API, use a tool, exchange sensitive information, or change a system. - The company’s Agent Authority Broker, or CAAB, is designed to address ambient authority, where AI agents or systems may inherit broad access without action-specific permission checks. - CAAB is intended to enforce scoped authority, verify permission at the point of action, and create proof before high-risk digital actions are executed. - Crittora says its authorization and encryption products are built on encryption, identity binding, permission enforcement, signed requests, and verifiable proof. - The company says its patent-pending quantum-resilient encryption technology is meant to provide a future-proof security foundation.

Between the lines: - The hire suggests Crittora wants a sales leader who can translate a technical security message into enterprise revenue. - The company is emphasizing a shift in cybersecurity from protecting systems to controlling AI-driven actions in real time. - Darke’s background in zero-trust, privileged access, and networking security fits Crittora’s pitch to regulated industries and large enterprises. - Crittora is trying to make AI governance a security buying decision, not just an IT experiment.

What's next: - Darke is expected to help Crittora build customer relationships, expand partnerships, and grow revenue as the company brings its technology to market. - Crittora will continue targeting organizations that need controls around how authority is granted, how data moves, and how digital actions are verified. - The company’s next challenge is turning its AI-agent security thesis into repeatable enterprise adoption.

The bottom line: - Crittora is betting that enterprise AI adoption will require strong action-level security, and it has hired a veteran sales executive to help sell that message.
