In this CUBE Conversation, Atri Chatterjee, chief marketing officer of DigiCert, joins theCUBE's John Furrier to discuss the evolution from digital trust to intelligent trust as AI agents, quantum computing and machine-scale identities reshape the security landscape. Chatterjee explains how intelligent trust operates on two axes: using AI to better manage cryptography, and using cryptography to authenticate and sign AI models and agents. He draws a direct parallel to website certificates — just as a browser trusts a domain through a certificate, AI models and agents must be cryptographically signed so organizations can verify provenance and detect tampering in what he describes as an emerging "agent bill of materials." The conversation also explores the urgent operational reality behind cryptographic automation. Chatterjee details how certificate lifespans are shrinking from 398 days today to just 47 days by 2029 — an 8x increase in certificate volume — and warns that organizations already experiencing two certificate-expiration outages per day could face one every hour. He also touches on the C2PA standard for signing AI-generated content, extending the same trust model that secured e-commerce to the era of deepfakes and autonomous content generation. Shifting to his own discipline, Chatterjee reflects on what it means to lead B2B marketing in the AI era, moving from keyword optimization to domain expertise and from mechanical campaign execution to data interpretation and strategy. From preparing cryptographic infrastructure for a quantum-capable future to redefining how enterprises govern AI agents at scale, he outlines why trust has graduated from a compliance checkbox to a foundational business strategy.
