AI Security & Governance

AI capability is moving faster than security, policy, and operational control. Teams cannot answer which data a system can access, which actions it may take, or how unsafe behavior will be detected.

When organizations bring us in

The commercial trigger

Agents touch sensitive data, call tools, influence decisions, cross trust boundaries, or must pass security and risk review.

Who owns the problem

Accountable technology leadership

CIO, CISO, data, risk, and product leaders accountable for governed AI adoption.

What we engineer

Technical controls that make AI behavior reviewable, bounded, and operable.

AI threat models and abuse cases

Prompt, model, tool, and data trust boundaries

Identity and authorization for agents

Adversarial and policy evaluation suites

Audit events, approvals, and escalation workflows

What makes it difficult

Consequence changes the technical work.

AI systems expand the attack surface through natural-language inputs, retrieved data, external tools, and probabilistic outputs. Governance in policy documents alone cannot constrain runtime behavior.

How we approach it

Architecture through controlled release.

  1. Map data, model, tool, and user trust boundaries
  2. Translate material risks into enforceable runtime controls
  3. Test prompt injection, data leakage, excessive agency, and failure handling
  4. Capture evidence that security, risk, and engineering teams can review
Buyer context

What has to be true before this investment works.

The security problem begins when an AI system can retrieve sensitive context, generate decisions, or operate tools across trust boundaries. Governance becomes useful only when policy is translated into runtime behavior, testable release criteria, incident response, and evidence an accountable owner can inspect.

Problems behind the search

Visible symptoms, technical causes, and the decision to make.

Policy cannot constrain production behavior

What the buyer sees
The organization has AI principles but cannot show how a disallowed action is prevented.
What causes it
Governance stopped at documentation and review committees instead of reaching identity, data, model, and tool controls.
What to evaluate
Ask for a control map that identifies enforcement point, owner, test, evidence, exception, and failure response.

The AI trust boundary is unknown

What the buyer sees
Teams cannot state which prompts, documents, plugins, tools, models, or users are trusted.
What causes it
The system was evaluated as a model rather than as a supply chain and execution environment.
What to evaluate
Require data-flow and threat models covering ingestion, retrieval, inference, actions, telemetry, and third parties.

Reviews cannot keep pace with change

What the buyer sees
Every prompt or model change triggers manual debate, while low-level updates bypass review entirely.
What causes it
Risk tiers, automated evaluations, release policy, and version evidence are missing.
What to evaluate
Evaluate whether material changes have proportional gates and routine changes have automated evidence.
Architecture depth

The design decisions underneath the outcome.

Identity before intelligence

Carry user, workload, tenant, and purpose identity through retrieval and action. A model recommendation never expands the permissions of the principal on whose behalf it operates.

Layered input and tool defenses

Separate system instructions from untrusted content, minimize retrieved data, validate outputs, and enforce tool policy in code. Detection complements these controls; it cannot substitute for them.

Evaluation as a release control

Test task quality alongside injection resistance, disclosure, excessive agency, bias risks relevant to the workflow, abstention, and safe failure. Bind results to the exact model, prompt, data, policy, and tool versions.

Operational governance

Provide traceable approvals, risk acceptance, exception expiry, incident runbooks, kill paths, rollback, and reporting suited to the people accountable for the system.

Material use cases

Where the system fits, and where people remain accountable.

Enterprise knowledge assistant

Retrieve permission-filtered documents and answer with source context.

Human accountability. Content owners govern sources; users remain responsible for consequential use.

Engineering constraints. Entitlement leakage, malicious documents, stale sources, retention, and citations.

Tool-using operations agent

Investigate a request and propose or execute bounded changes.

Human accountability. Service owners approve material actions and own restoration.

Engineering constraints. Least privilege, action validation, idempotency, blast radius, and emergency stop.

AI-assisted decision workflow

Prepare evidence and a recommendation for an established business decision.

Human accountability. The designated human or rules engine owns the decision.

Engineering constraints. Explanation, data quality, prohibited factors, appeal, reproducibility, and drift.

Implementation sequence

From system truth to an operated release.

  1. 01

    Inventory AI execution paths

    Map models, prompts, retrieval stores, tools, data classes, users, vendors, and decisions across production and unofficial use.

  2. 02

    Tier decisions by consequence

    Separate assistance from recommendations and autonomous action, then assign approval, evaluation, and evidence requirements.

  3. 03

    Define trust and data boundaries

    Specify identity propagation, tenant isolation, residency, retention, provider exposure, and prohibited data flows.

  4. 04

    Exercise adversarial behavior

    Test prompt injection, data exfiltration, unsafe tool use, authorization mismatch, model failure, and bypass attempts.

  5. 05

    Install release and runtime controls

    Gate prompt, model, retrieval, and tool changes while monitoring policy decisions, drift, spend, and overrides.

  6. 06

    Produce reviewable governance evidence

    Connect policies to operating controls, owners, exceptions, evaluations, incidents, and versioned approvals.

Failure modes

How production breaks, and what the architecture must do next.

Indirect prompt injection

Signal. A document, webpage, or tool response attempts to redirect the system.

Architecture response. Isolate untrusted content, restrict tools, validate proposed actions, and evaluate known and workflow-specific attacks.

Sensitive-data disclosure

Signal. Responses or traces expose information outside user, tenant, or purpose boundaries.

Architecture response. Filter retrieval before inference, minimize context and telemetry, apply output controls, and test cross-tenant cases.

Unsafe fallback

Signal. When a control or provider fails, the workflow silently chooses a less governed path.

Architecture response. Define fail-closed behavior for material actions and make degraded modes explicit, observable, and reversible.

Control drift

Signal. A model, connector, role, or dataset change invalidates the approved control assumptions.

Architecture response. Continuously inventory versions and dependencies, rerun proportional evaluations, and expire approvals when boundaries change.

Buyer evaluation

Questions to resolve before selecting an approach.

  • Where is each policy enforced at runtime?
  • What untrusted content can influence the model?
  • Which identities reach retrieval and tools?
  • What changes trigger re-evaluation or re-approval?
  • Can operators contain and reconstruct an AI incident?
Buyer questions

Frequently asked before an engineering engagement.

Is an AI policy enough to govern agents?

No. Policy defines intent and accountability. Runtime identity, authorization, data controls, evaluation gates, monitoring, human approval, and incident procedures make that intent operable.

How do you test prompt injection?

Start from the actual workflow and tool permissions. Test direct and indirect instructions, encoded content, conflicting sources, data-exfiltration attempts, tool manipulation, and multi-step attacks. A pass requires both safe behavior and evidence that external controls stopped prohibited actions.

What should an AI audit trail contain?

Enough to reconstruct the material event: principal and purpose, system and model versions, relevant source identifiers, policy decisions, tool requests and results, approvals, outcome, and exception state. Avoid copying sensitive prompt content when identifiers or protected references suffice.

How is AI governance different in regulated workflows?

The architecture must reflect the specific decision, data, jurisdiction, product role, and accountable authority. Regulatory labels alone do not define the control; counsel, risk, security, clinical, or other domain owners establish applicability.

Engineering depth

Decisions, controls, and failure modes.

Architecture decisions

  • Separate identity, data, model, and tool trust boundaries.
  • Enforce permissions at runtime rather than relying on prompt instructions.
  • Treat retrieved content and tool output as untrusted inputs.

Operating controls

  • Continuously test injection, leakage, excessive agency, and unsafe fallback behavior.
  • Route material decisions through defined approval and escalation paths.
  • Preserve reviewable evidence without retaining unnecessary sensitive content.

Failure modes we plan for

  • A user or document attempts to override system policy.
  • An authorized tool is used outside the purpose of the request.
  • A control exists in policy but is absent from the execution path.
