uygnoey Agentic risk assessment
The job is not zero risk. The job is to make agentic risk legible and bounded, so risk can be deliberately accepted by someone with the authority to accept it, and the business moves on your terms instead of around you.
Saying "no" produces shadow adoption — zero telemetry and generally no off switch. Saying "yes" without controls produces incidents.
Instructions
1. Run the four questions
For every agentic use case that reaches review, answer all four. Full definitions and scoring guidance: references/four-questions.md.
- What untrusted content does it ingest? Untrusted means anything an attacker could plausibly write or alter — outside email, the open web, third-party documents, public repositories. If the answer is "nothing," the agent-specific risk is near zero: move quickly.
- What actions can it take, and on whose behalf? Read-only is a different concern from read/write. Tool calls, code execution, and network egress each widen the aperture. Every action happens under some identity; know whose.
- What is the blast radius if it is misaligned? Scope × severity. Did the bad actor or alignment incident have access to one file or the whole org? Anomaly, annoyance, data exposure, or true incident?
- What observability do I have? Can you tell agent actions from user actions? Does it land in your SIEM?
Record the answers in templates/risk-review.md.
2. Apply the principle of least agency
The four answers give you a picture of the risk. The principle of least agency tells you what to do with it: grant the narrowest capability that still completes the task.
Default posture: admin-paced rollout — enable a small group, watch the telemetry, then expand access.
3. Locate the deployment on the identity spectrum
Every deployment sits somewhere between two ends. See references/identity-spectrum.md.
- System service account — self-contained, single-purpose, least-privilege identity doing exactly one thing for the business, with no human identity attached.
- Human credential — a person at a keyboard is accountable for the outcome, the same way they are for anything else done with their credentials.
- The ambiguous middle — an agent carrying a person's delegated identity into systems that person is not watching. Ambiguous accountability is how incidents become unexplainable. Push a deployment toward one end or the other.
Treat a misaligned agent as an insider threat, not a perimeter problem. The operational difference is response time: the Ponemon Institute's 2026 Cost of Insider Risks report found organizations took an average of 67 days to contain an insider incident. At agent execution speeds, responses measured in days are too long.
4. Check the deployment against the seven controls
Each control is a requirement any agent environment should be able to meet. Full text of each, with what to ask a vendor: references/deployment-controls.md.
- Identity comes from your IdP — issued and revoked where you already issue and revoke everything else, with your existing groups as the unit of policy.
- Connector allowlists draw your data boundary — the decision about which connectors are on is the decision about which data the agent can reach.
- Per-tool, per-action approval — remove individual verbs, not just whole connectors. If the failure mode that keeps you up at night is "the production database gets deleted," remove the delete verb from the agent's world entirely. It will never attempt an action that isn't in its tool list.
- Sandboxed execution — the environment the agent loop runs in should never hold a credential worth stealing.
- Egress allowlisting — the strongest control against prompt injection. If an agent is compromised by something it read, the attacker still has to get data out; when outbound requests can only reach domains you chose, there is nowhere attacker-controlled to send anything.
- Telemetry to your SIEM over OpenTelemetry — agent actions must be distinguishable from user actions in the system where you already investigate. A stream you can point somewhere, not a dashboard you have to visit.
- An org-wide off switch — plus narrower layers (RBAC by group, per-connector write disable) mapped out before you need them.
5. Write down your trust boundary
Write down what counts as untrusted content in your environment. Every future agent decision gets easier once that line exists. Use templates/trust-boundary.md.
If data must cross the boundary, route it through DLP or DSPM controls. Where a connector touches untrusted sources, require human review for any destructive or one-way decision — for example, a personal agent doing email with web search in its input should be allowed to create draft emails and never to send externally without human review.
6. Design for six months out, not for today's model
If you design your program for what the model can do today, you will be behind by the time it launches. Increased model intelligence enables more degrees of freedom and obsoletes elaborate scaffolds with meticulous prompts; if you lean on those for controls, they will be cut out of future generations of internal applications, leaving you without a control point.
Limit access and actions, not what you believe today's model limits are. New capabilities can appear within the boundaries of an existing deployment without any change to tools, permissions, or prompts — see examples/incident-response-agent.md.
7. Keep governance from becoming the bottleneck
- Take the risk register first. A register reviewed quarterly can't govern systems that change faster than the governance process can document new risks. Automate it, possibly by integrating an agent with the security review process.
- Understand who built the agents and why. People route around security because the sanctioned path is slow — that is the origin of most shadow adoption. A compliance analyst who can build the tool they need, where you can see it, isn't shadow adoption.
- Human accountability is part of the workflow. Deliberately accepting risk is an act performed by humans with the authority to accept it. With a live risk register and an executive risk council behind it (ISO 42001 or similar), re-scores reach the people who can accept them and flagged vendor terms reach the people who negotiate them. If you already have ISO 27001, adding 42001 is often an incremental addition with your current auditor.
8. Getting started
- Pick the agentic use case with the most internal pressure and run it through the four questions. The goal is to find the conditions under which you would approve it, not to produce a verdict.
- Take the seven requirements to the teams and vendors you already pay. Ask your IdP, your SIEM, and any agent vendor which of these they can show you working in your stack today.
- Decide your trust boundary and write it down.
Examples
Bounded service-account agent (approve and move)
An incident response agent with read-only production logs (no PII), Slack access to open and run the incident channel, and the ability to draft a postmortem doc. Four questions: no untrusted content; reads everywhere, writes limited to new documents and Slack messages; worst constructible outcome is mildly sensitive log lines in an already-locked-down channel; every action lands in the SIEM. Not risk-free, but a bounded write surface with full audit coverage. Walkthrough, including the emergent agent-to-agent behavior that appeared after a model upgrade: examples/incident-response-agent.md.
Human-credential agent harness (bound with the seven controls)
A personal agent harness on an employee's machine or in a hosted session sits at the human operator end of the spectrum. The four questions produce different answers for every use case, so risk is bounded by controls rather than by a single verdict: IdP identity, two-gate connector allowlists, per-action approval, a sandbox that holds no credential worth stealing, mandatory egress proxy, OpenTelemetry to your SIEM, and a single org-wide off switch. Walkthrough: examples/personal-agent-harness.md.
Governance agents you run yourself
GRC teams can run their own agents — drafting security-questionnaire responses, and reading vendor questionnaire responses and subprocessor-change notifications to flag the ones that should be objected to. See the companion subagent definitions shipped alongside this post.
