What this looks like in practice
The problem
Financial-services AI agents that touch trading systems, account data, or customer records need identity assurance that satisfies FINRA and SEC expectations for attributable, revocable access. Most non-human identity programs were not built for this: they were built for static service accounts and long-lived API keys, shared across a set of automated jobs that rarely changed. Agents don't fit that model — they spawn, act on a task, and need to be individually revocable without taking every other agent down with them.
The consequence of forcing agents into a service-account model is an access log that cannot answer the question a regulator or internal auditor actually asks: which specific agent instance did this action, and can it be shut off without affecting anything else running under the same shared credential.
What good looks like
A well-identified agent fleet gives every agent instance its own credential, distinct from every other agent's, so an action in a trading or account system traces to exactly one attributable principal rather than a shared key covering dozens of jobs. Credentials rotate on a schedule without downtime — an overlap window keeps a task running on its current credential while a new one comes into effect, rather than forcing a hard cutover that risks an in-flight transaction failing mid-execution.
When one agent needs to be shut off — because it's misbehaving, because a task is complete, because an incident is underway — that revocation is scoped to the single agent's credential, and every other agent in the fleet keeps running unaffected. The humans who configure and manage the agent fleet authenticate through the organization's existing SSO, SAML, or OIDC identity provider with MFA, so the control plane governing the agents is held to the same access standard as any other sensitive financial system.
How Praesidia helps
Praesidia issues a distinct, rotatable credential to every agent, so no two agents in a financial-services deployment share a single identity and every logged action attributes to exactly one principal. Key rotation runs with a zero-downtime overlap window, meaning a credential can be rotated on schedule without interrupting whatever task the agent is mid-execution on when rotation occurs.
Revocation is scoped to a single agent: pulling one agent's access does not require rotating or disrupting credentials belonging to any other agent in the fleet, which is what lets a security team contain an incident involving one agent without taking down the trading or account-servicing capability the rest of the fleet provides. SSO, SAML, OIDC, and MFA govern the human operators who configure and manage agents, so the control plane itself sits behind the same identity assurance financial-services organizations already require elsewhere. The identity and access for AI guide covers how these controls extend the identity model your organization already runs to a non-human population.
Getting started
- Inventory every credential currently shared across more than one agent — this is the population most likely to fail an attribution test today.
- Move high-consequence agents (trading, account access) to per-agent credentials first, before addressing lower-stakes internal automation.
- Set a rotation schedule with an overlap window so rotation becomes routine rather than a risky, manually scheduled event.
- Test single-agent revocation before you need it in an incident — confirm pulling one agent's access does not require touching any other agent's credential.
- Bring human operator access under the same SSO/MFA standard as the rest of your financial-systems access, since the control plane is itself a sensitive system.
FAQ
How is agent identity different from a service account? A service account is typically one shared credential covering many operations by many people; agent identity is issued per agent instance, so every action traces to exactly one attributable, individually revocable principal.
Can one agent be revoked without disrupting the others? Yes — revocation scoped to a single agent's credential does not require rotating or interrupting credentials belonging to any other agent.
What do FINRA/SEC expectations imply for agent access records? Attributable, auditable access records per actor, which a shared service-account model cannot produce but a per-agent identity model does by default.
