At CyberArk’s Workload Identity Day Zero in Atlanta, just before KubeCon 2025, industry leaders gathered to address the growing challenges of non-human identities (NHIs), workload authentication, and AI agent governance. The common thread? Traditional human-centric identity approaches no longer scale in a world of ephemeral workloads, multi-cloud environments, and autonomous agents.

The Current State of Workload Authentication

Speakers emphasized that most workload identities, including services, CI/CD jobs, Lambdas, and autonomous agents, still rely on long-lived API keys, often overprivileged and difficult to manage. While PKI systems exist, they are complex and require specialized expertise, creating operational friction. Multi-cloud, hybrid architectures, and diverse tech stacks exacerbate the challenge, making ad hoc solutions the norm rather than the exception. The result: any compromised workload credential can create a massive, invisible attack surface.

SPIFFE/SPIRE as a Foundation

Andrew Moore, Staff Software Engineer at Uber  showcased how SPIRE has become the “bottom turtle” of Uber’s identity strategy, enabling billions of workload attestations per day. Using a SPIFFE-based identity fabric, Uber enforces trusted boot, agent validation, and tight SPIFFE IDs to maintain secure, scalable workload authentication at massive scale.

Agentic AI Needs Identity Governance

Brett Caley, Senior Software Security Engineer at Block emphasized that AI agents are workloads too. Assigning names to agents may be fun, but they still require narrowly scoped permissions, explicit authorization, and accountability. Failures are not about what AI does, but how the system governs its identity and privileges.

Cross-Cloud AI Agent Identities

Dan Choi, Senior Product Manager, AWS Cryptography, and Brendan Paul, Sr. Security Solutions Architect from AWS, demonstrated how SPIFFE Verifiable Identity Documents (SVIDs) can serve as short-lived, universal identities for AI agents. Using SPIRE, workloads can authenticate and exchange scoped credentials securely across clouds. Their “AI-enabled coffee shop” demo illustrated user-to-agent identity propagation, least-privilege access, and clear attribution in multi-cloud scenarios.

From Heroic Projects to Boring Infrastructure

The next phase of workload identity focuses on making strong identity the default plumbing. SPIFFE/SPIRE, OAuth token-exchange patterns, and transaction tokens will quietly become standard practice, enabling secure CI/CD pipelines, microservices, and AI agents at scale. Organizations must:

• Inventory workloads and machine identities.
• Adopt short-lived credentials and centralized policy.
• Log and enrich events for observability.
• Create safe, golden paths for experimentation.

The Future of NHI Governance

The consensus: identity must become automatic, invisible, and enforceable, balancing flexibility for developers with robust security. With agentic AI, it’s essential to ask: “What is this workload allowed to do, on whose behalf, and under which guardrails?” By addressing these challenges now, enterprises can reduce secret leakage, enforce least privilege, and scale non-human identity governance effectively.

CyberArk’s Workload Identity Day Zero highlighted that understanding today’s inventory and designing for identity-first security is the critical step toward a safer, more manageable future for workloads and AI agents.
