Agent swarms and shared filesystems: what IAM teams should rethink

TL;DR: Agent swarms are increasingly using filesystems as a coordination layer, but 1Password argues that shared disks alone cannot express intent, authority, or accountability at production scale. The real requirement is an identity layer that binds scoped, revocable access to each agent so swarm behaviour remains legible and controllable. Editorial analysis by NHI Mgmt Group, based on content published by 1Password: “Agents are making filesystems cool again”. Key questions Q: What breaks when AI agent swarms rely on shared filesystems for coordination? A: They lose a clear boundary between collaboration and authority. Q: Why do shared filesystems create risk for agent swarms? A: Shared filesystems create risk because they blend coordination, persistence, and access in the same layer. Q: How should security teams govern AI oversharing when users already have access to sensitive files? A: Security teams should treat file access as only the starting point, not the control boundary. Practitioner guidance Define the swarm’s authority boundary Map which directories, mounts, and shared paths are truly required for each agent role, then remove ambient access that is only there for convenience. Issue explicit agent identity Require each agent to authenticate as a distinct non-human identity so reads, writes, and approvals can be attributed to a specific executor. Scope access by lease duration Make filesystem access time-bound and revocable so the access grant ends with the task rather than persisting with the runtime. Bottom line: AI agent swarms can coordinate through shared filesystems, but coordination alone does not provide identity, authority, or accountability.

Shared filesystems are becoming the default swarm control plane, but they are not an identity model. They solve coordination and persistence, not intent, authority, or accountability. That distinction matters because governance breaks the moment storage design is mistaken for access design. Practitioners should treat the filesystem as a dependency surface, not an authorisation boundary.

A few things that frame the scale:

Only 44% of developers are reported to follow security best practices for secrets management, exposing a significant developer behaviour gap, according to the State of Secrets in AppSec.

A question worth separating out:

Q: What is the difference between shared storage and identity control for AI agents?

A: Shared storage lets agents exchange context and artifacts. Identity control determines who may access which paths, for what purpose, and under what revocation rules. The first supports coordination, while the second makes that coordination governable in production.
