Connector sprawl without ownership breaks enrichment the first time a feed changes schema.
Filigran
Deploy OpenCTI your analysts can use on day one
OpenCTI rollouts often ship empty tenants — connectors half-configured, roles unclear, and STIX objects nobody trusts. Analysts revert to spreadsheets while leadership wonders why the platform investment has not shortened enrichment time.
Connectors Roles and data model Scoped rollout Analyst-ready
Why this matters
Why this matters
Scoped deployment with data model and connector discipline is what turns OpenCTI from a repository into an operations platform.
RBAC and organization boundaries matter before intel data sensitivity scales.
Integration with Splunk ES should be planned during deployment — not bolted on after go-live.
What you get
Clear outputs you can use
Scoped OpenCTI architecture and deployment: environment design, connectors, roles and groups, core data model, and priority entity types — with handover runbooks and a clear path to Splunk ES or SOAR integration.
- ✓ Deployed OpenCTI environment for agreed scope (connectors, roles, core data model)
- ✓ Connector and entity standards documentation analysts and engineers can extend
- ✓ Integration readiness notes for STIX/TAXII and Splunk ES or SOAR handoffs
Why teams talk to GKC
Calm, practical, and grounded in the environment you already have
SOW tied to connector and use-case count — expansions are change-controlled
Workflow outcomes — cases, enrichment, and prioritisation — not box installation

What happens next
A straightforward first step
We keep the first step straightforward so you can understand fit, scope, and likely value before deciding what to do next.
1
Agree scope and use cases
We confirm priority intel types, connectors, roles, and compliance constraints with intel and platform owners.
2
Build and validate platform
OpenCTI configuration, connectors, and data model are implemented with analyst review on representative workflows.
3
Hand over for day-2
You receive runbooks, standards, and backlog for integration or additional connectors.
Questions teams often have
Common questions
Can Filigran PS deploy this instead?
Vendor PS focuses on their product. We deliver bounded outcomes sized to your SOC workflows and Splunk ES integration path.
Will you write Splunk ES detections in this engagement?
Detection engineering stays on the Splunk ES hub. Deployment includes integration readiness; detection work is separately scoped.
Do we need every connector on day one?
No. Scoped deployment prioritises feeds and use cases that change analyst outcomes first — expansions are explicit.
