Trust architecture

Trust the architecture, not the vendor

Security-sensitive enterprises should not have to rely only on a vendor's assertions about how an agent is controlled. Cogward is built so that execution, enforcement, sensitive state, and evidence stay inside the environment where the owning security team can inspect, test, operate, and verify them.

This page describes the trust architecture. See the capability map for what is available today, in preview, and planned.

Four trust properties

What holds when the vendor's word is not enough

Trust lives in properties the owning security team can check for itself, across every deployment.

Execution ownership

Runs inside your boundary

Agents execute inside the software-vendor or enterprise trust boundary the product requires.

Inspectable enforcement

A path you can test

Security teams can inspect and test the runtime path that governs actions that change something.

Verifiable evidence

Verify without a dashboard

Evidence can be retained and verified without depending on a vendor-hosted dashboard.

Portable control contract

One model, many environments

The same identity, policy, lifecycle, and evidence model can operate across deployment environments.

Threat model

Assume the agent can be wrong, manipulated, or compromised. Bound what happens next

Each scenario below assumes the agent's behavior cannot be trusted. The runtime does not try to prove the agent will behave; it bounds the authority, reach, persistence, and blast radius available to it when it does not.

Assume this can happen What the runtime bounds
Prompt injection influences tool useRuntime mediation at the execution boundary: every tool call is evaluated against policy and delegated scope before it runs, so injected content is bounded rather than trusted.
Agent attempts an unapproved API callRuntime mediation and policy: only approved destinations are reachable through the governed path; unapproved calls are denied and recorded.
Agent sends data to an unapproved destinationControlled network egress: data can leave only through approved routes; other destinations are not reachable from the sandboxed runtime.
Tool definition changes after approvalIntegrity and version binding: tool identity is bound at approval, so a changed definition is re-evaluated rather than silently trusted.
Delegated authority exceeds the permitted scopeDelegation ceilings: authority narrows at each boundary; downstream agents cannot receive more than the upstream principal and agent contract permit.
One tenant's state is exposed to anotherTenant isolation: execution, state, and evidence are tenant-scoped at the runtime boundary rather than in application code.
Agent enters a costly loopResource and cost ceilings: runtime-enforced limits suspend or terminate a run that exceeds its bounds, independently of agent behavior.
Agent version degrades without a code deploymentProduction evaluation and lifecycle authority: drift can be scored against per-version baselines and connected to gating, containment, or rollback.
Compromised code attempts to bypass framework hooksRuntime boundary and credential custody: enforcement sits below the framework, and the agent's only route to models and tools is the governed path.
Human approval is missing or ambiguousApproval as a first-class runtime state: actions that require approval wait at the boundary rather than proceeding.
Model provider behavior changesEvaluation and evidence: behavior can be scored against baselines and recorded, so a change is attributable and can trigger a lifecycle action.
An agent continues after it should have been containedLifecycle authority: stop, suspend, contain, and roll back are runtime operations, not advisory flags the agent can ignore.

Cogward limits authority, reach, persistence, and blast radius even when the agent's behavior cannot be trusted. It does not claim to prevent all compromise.

Responsibility boundary

The runtime owns the execution boundary. Specialist systems own their layer

Cogward is the execution point where verdicts from specialist systems can be enforced and recorded. It does not reinvent the content-layer and security tools you already run.

Complementary systems own

  • Prompt-injection detection
  • Toxicity filtering
  • Model safety
  • Data classification
  • Data-loss prevention
  • Endpoint security
  • Vulnerability scanning
  • Enterprise IAM
  • SIEM
  • GRC workflow

Cogward owns

  • Runtime isolation
  • Execution identity
  • Delegated authority
  • External-action mediation
  • Lifecycle control
  • Approval enforcement
  • Resource limits
  • Runtime evidence
  • Production behavior context

A verdict from a content-security or classification system becomes an enforced, recorded outcome at the point where the agent actually acts.

Evidence integrity

Evidence that remains useful when the dashboard is unavailable or the vendor is no longer in the path

Evidence is generated directly by the runtime, retained inside per-tenant boundaries, and structured so it can be verified independently. Records are append-only or tamper-evident. Signing or anchoring can be customer-controlled, and inclusion and consistency can be verified from the record itself. Sensitive content stays referenced rather than stored inline, so the record can be exported offline while still attributing identity, version, policy, approval, and action. The evidence stack is in preview as the ledger reaches production; the capability map carries its current status.

Evidence integrity and verificationtechnical

What problem is being solved. Operational telemetry answers engineering questions in the moment; evidence has to stay trustworthy for a security review, audit, or investigation that may happen long after the run, and possibly without the vendor in the path. The two records are separated so the evidence record can be verified on its own terms.

What the trust and failure boundary is. Evidence lives inside a per-tenant boundary, and its integrity boundary is cryptographic rather than procedural: whether a record is present, and whether history was silently rewritten, is decidable from the record and its proofs. Trustworthiness does not depend on the vendor remaining reachable.

What happens during failure or attempted bypass. Silent alteration or removal of a record is detectable through inclusion and consistency verification against a signed root. Lawful deletion is handled by redaction that removes content while preserving the structural position, so records above and below stay verifiable.

Which data and control elements remain local. Sensitive payloads remain in customer-controlled storage and are referenced by content hash and classification. Anchoring and signing keys can be held by the customer. Records stay tenant-scoped and exportable offline into the systems the organization already runs.

How it integrates with the rest of the runtime. Because evidence is produced by governed execution rather than reconstructed from disconnected logs, each record carries version, identity, policy, approval, and action attribution from the same execution boundary that enforced the control.

Named primitives

  • Hash chains
  • Merkle trees
  • Transparency-log structures
  • Signed roots
  • Customer-controlled KMS keys
  • Immutable object storage
  • WORM retention
  • Independent verifier tooling
  • Content hashes
  • Payload references

Cryptographic integrity demonstrates that recorded evidence has not been silently altered or removed without detection. It does not independently prove the truth of the original event.

Security and compliance support

Runtime evidence for the reviews your customers already perform

Cogward produces structured controls and evidence that can support security, risk, audit, and compliance processes.

Control categories

Framework examples

On compliance

Exact control mappings depend on the customer's deployment, use case, policies, and broader control environment. Cogward provides runtime controls and evidence; it does not make an organization compliant by itself.

Export operational and evidence records into the observability, SIEM, audit, and GRC systems already used by the organization.
