The process of directing logs and events to different destinations based on value, urgency, and investigative need. In mature SOC designs, routing is a security control because it determines which events remain searchable in the SIEM and which are archived more cheaply.
Expanded Definition
telemetry routing is the policy-driven process of deciding where security logs, alerts, and event data should go after collection. It is not just an ingestion pipeline function. In a SOC, routing determines whether a record lands in a high-cost SIEM index for immediate search, a ticketing workflow for triage, a cold archive for retention, or a specialised analytics store for later investigation. Good routing balances investigative value, retention obligations, performance, and cost.
Definitions vary across vendors because telemetry routing can be embedded in collectors, brokers, SIEM rules, SOAR playbooks, or cloud-native logging services. NHI Management Group treats it as a governance control as well as an engineering pattern, because routing decisions influence visibility, evidential integrity, and response speed. That makes it closely aligned with the NIST Cybersecurity Framework 2.0 emphasis on observable, actionable security telemetry, even though NIST does not define the term as a standalone control label.
The most common misapplication is treating telemetry routing as a pure cost-saving exercise, which occurs when organisations down-tier critical events before confirming they remain searchable for detection and incident response.
Examples and Use Cases
Implementing telemetry routing rigorously often introduces policy complexity, requiring organisations to weigh faster investigations against storage cost, analyst workload, and data retention requirements.
- High-severity authentication failures are routed into the SIEM in near real time, while routine health checks are sent to lower-cost storage for trend analysis.
- Cloud control plane events are duplicated to both a detection platform and an immutable archive so analysts can correlate activity while preserving evidence.
- Privileged session logs are routed to a dedicated review queue because PAM investigations need richer context than standard application telemetry.
- Agent and AI agent execution logs are sent to a separate workspace so tool use, prompt inputs, and action traces can be reviewed without blending them with user activity.
- Long-retention compliance events are archived after an initial detection window, while selected indicators are forwarded to CISA guidance-aligned workflows for response prioritisation.
Why It Matters for Security Teams
Telemetry routing matters because the wrong destination can erase operational value even when the raw event was collected correctly. If critical logs never reach searchable storage, defenders lose detection coverage, response teams lose context, and forensic investigators may be left with gaps that cannot be reconstructed later. If everything is routed into the highest-cost tier, teams often end up overloading the SIEM, degrading search speed and burying the signals that matter most.
This term also intersects with identity and NHI governance. Privileged access events, service account activity, secrets access, and agent tool invocation logs are all forms of telemetry that may require different handling than general endpoint data. Routing choices should reflect the sensitivity of the identity event, the expected investigative path, and the retention rules that apply to the dataset. Guidance from OWASP NHI guidance and the logging principles in OWASP Logging Cheat Sheet are useful reference points when telemetry includes machine identities or agent activity.
Organisations typically encounter the real cost of poor telemetry routing only after an incident review reveals that the relevant records were archived too early, routed to the wrong system, or never indexed for search, at which point telemetry routing becomes operationally unavoidable to address.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 and OWASP Agentic AI Top 10 address the attack surface, NIST CSF 2.0 and NIST SP 800-53 Rev 5 set the technical controls, and ISO/IEC 27001:2022 define the regulatory obligations.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | DE.CM | CSF monitoring outcomes depend on collecting and routing telemetry that stays usable for detection. |
| OWASP Non-Human Identity Top 10 | NHI guidance covers logging and visibility for machine identities and agent activity. | |
| OWASP Agentic AI Top 10 | Agentic AI security depends on tracing tool use, actions, and execution context. | |
| NIST SP 800-53 Rev 5 | AU-2 | Audit logging controls depend on deciding what events are captured and where they are stored. |
| ISO/IEC 27001:2022 | A.8.15 | Logging requirements in ISMS programs require controlled handling and retention of event data. |
Route high-value events to searchable monitoring paths and preserve evidence for detection and response.
