is connected.
Zof maps your services, APIs, and dependencies so your team knows what to test when something changes.
Temporal
what exists, what changed, when, by whom
Blast radius
resolved before the action runs
Policies
mapped to the systems they protect
Scoped
to approved systems and access
Entities, relationships, and time
Repositories, commits, pull requests, services, APIs, endpoints, components, databases, tables, queues, infrastructure, environments, deployments, agents, models, tools, policies, controls, tests, evidence, incidents, owners, and data classifications.
- 01
Relationships that carry consequence
DEPENDS_ON, CALLS, READS, WRITES, DEPLOYS_TO, OWNED_BY, PROTECTED_BY, VERIFIED_BY, AFFECTS, GENERATED_BY, APPROVED_BY, USES_MODEL, USES_TOOL, SATISFIES, and VIOLATES.
- 02
Temporal by design
What exists, what changed, when it changed, who or what changed it, what depended on it, what evidence existed, what policies applied, what decision was made, and what happened afterward.
- 03
Blast radius before action
Every proposed change resolves to affected systems, criticality tier, applicable controls, historical incidents, and the verification required.
- 04
Shared by the whole loop
Verification, evidence, and control all read from the same graph, so every decision is grounded in one understanding of the enterprise.
Outcomes teams measure
Size the blast radius before shipping
See exactly which systems, data, and customers a change can affect, and how critical they are, before it is allowed to run.
Tier 0
criticality resolvedRequire the right verification
Controls mapped to affected systems determine the evidence a change must produce, so verification is targeted rather than exhaustive.
Policy
selects the evidenceReconstruct any decision
Walk back from an incident to the change, the evidence that existed, the policies that applied, and who approved it.
Temporal
history stays queryableGive leadership one risk view
One graph shows where risk concentrates, where controls apply, and what changed recently.
One
source of truth
The substrate of the control loop
The System Graph is not a standalone feature. Verification reads it to decide what must be proven, Evidence writes to it, and Control relies on it to size risk.
Verification Engine
Selects the evidence each change requires from the systems and controls the graph resolves.
Evidence
Every bundle, approval, and outcome is written back to the graph, so history is queryable.
Control Plane
Policy decisions are grounded in criticality, affected systems, and incident history from the graph.
- Continuous verification under your control layer
- System Graph maps dependencies before changes ship
- Audit-grade evidence for compliance reviews
