Contour
Service maps that build themselves.
Contour ingests Pathfinder's live discovery data and builds complete service maps without a single manual entry — then computes blast radius with a deterministic BFS algorithm so your team knows the full scope of any change or failure before it happens.
Service maps are outdated diagrams nobody trusts when it matters most.
Every team has service maps. They were accurate six months ago — before the last three migrations, the containerization project, and the team turnover. When an incident fires or a change request lands, engineers spend the first 30 minutes figuring out what's actually connected to what. Contour makes the map live: automatically rebuilt from what Pathfinder actually observes, not what someone thinks is true.
Not service-aware in name.
Service-aware in reality.
Contour doesn't just know which services exist. It tracks who is using each service, at what rate, and with what patterns — then continuously pushes that live intelligence to every downstream system that depends on it. Incident response, executive reporting, compliance evidence, and architecture decisions all run on Contour's live service model.
Request rates and active caller counts per service — continuously updated from Pathfinder's behavioral feed, not from a polling scan.
Active callers are tracked at the service level. Not just 'is this service up' — but which systems are actively consuming it and at what volume.
Topology, blast radius, and service state push natively to Vantage, Compass, Architect, and Trust in real time — no scheduled exports, no middleware.
Every downstream consumer sees the live map. Changes propagate the moment Pathfinder observes them — not at the next batch window.
Four steps, end to end.
Subscribe to the live discovery stream
As Pathfinder confirms new CIs and relationships, they feed directly into Contour's topology model in real time. No batch imports, no scheduled syncs.
Build service maps automatically
Service relationships, dependency chains, load balancer and firewall layers, and certificate bindings are modeled without manual input. Maps update when the environment changes — not when someone remembers to update the diagram.
Compute blast radius per node
Contour runs a deterministic, cycle-safe BFS algorithm across the current topology, pre-computing impact scope for every node. Change a node — Contour already knows what breaks.
Store state bitemporally
Every version of every map is committed to an immutable bitemporal store. You can replay the topology as it existed at any past timestamp — for post-incident review, compliance, or audits.
Built for the people who own this problem.
Change Manager / CAB Member
Reliable blast radius data before approving changes — not estimates written by the team requesting the change.
Service Owner
A live map of every upstream and downstream dependency, updated automatically as the environment changes.
IT Operations Manager
The ability to know scope immediately when an incident fires, without spending 30 minutes reconstructing topology.
Platform / Infrastructure Engineer
A topology history that lets them replay what the environment looked like at any point in the past.
Built different.
Four capabilities you won't find assembled anywhere else.
Zero-touch map generation
Pathfinder discovers. Contour builds.
Service maps are generated and maintained automatically from live behavioral data. If a new service appears, it's in the map. If a dependency changes, the map changes. No manual updates, no topology diagrams, no stale Confluence pages that nobody trusts.
Deterministic blast-radius computation
A real algorithm. Not an estimate.
Contour's blast-radius uses a deterministic, cycle-safe breadth-first search — not a heuristic. Given the same topology, the same query always returns the same scope. This reproducibility matters for change management approval, compliance documentation, and post-incident analysis.
Scope classification
Isolated / Service / Domain / Enterprise.
Instead of a raw node count, Contour classifies blast radius into four levels. Isolated: single service, no downstream. Service: contained within a service boundary. Domain: multi-service, same domain. Enterprise: cross-domain impact requiring executive escalation. Each level maps to a defined response protocol.
Bitemporal immutable history
Replay any moment in the past.
Every topology state is stored bitemporally and immutably. You can answer: what did the service map look like the moment the P1 started? What dependencies existed before the last change window? No reconstructions, no guessing — the actual recorded state.

Indicators and intelligence,
grounded in this product.
Contour feeds live service relationship data into Intelligence, which scores dependency risk and blast radius using competing models — traffic-based, relationship-class-based, and historical incident-based. The model that survives falsification determines the service health rank.
- —Service health score
- —Dependency risk index
- —Blast radius estimate
- —SLA alignment score
- —Upstream dependency count
- —Downstream exposure
- —Relationship class coverage
- —Cross-domain link health
- —Change blast radius
- —Impacted service count
- —Recovery complexity score
- —Cascading failure index
Where Contour fits in the platform.
Contour can ingest manually imported topology data as well, but its full power comes from the live Pathfinder feed — maps that are as accurate as the discovery layer is current.
