Start with monitored use cases
Wazuh can collect endpoint security telemetry through agents and process it through its documented central components. Start with a bounded use case: endpoint inventory, file-integrity events, authentication monitoring, vulnerability visibility, or a small detection workflow. A long agent list without an analyst question creates ingestion cost and alert noise.
Inventory endpoint populations, operating systems, network paths, owner teams, and whether an agent can be installed. Include servers, workstations, cloud workloads, and exceptions. The result drives enrollment, certificate, capacity, and support planning.
Map the Wazuh architecture
Use the current Wazuh architecture guidance to map agents, manager services, indexer storage, dashboard access, enrollment, certificates, and monitoring. Show which network paths are permitted and where persistent data lives. Keep administrative dashboard access separate from agent-to-manager traffic.
Plan version compatibility and certificate lifecycle before rollout. Enrollment is an access boundary: decide who may introduce an endpoint, how it is identified, and how a lost or retired device is removed.
Measure ingestion and set retention
Retention should follow use cases, expected query windows, compliance needs, storage capacity, and the sensitivity of events. Measure representative endpoint volume and peak bursts. Endpoint telemetry may include usernames, paths, command lines, and network details, so decide who can search it and how long it remains available.
Test query behaviour at the time ranges analysts will use. A policy that keeps data but makes incident queries unusable has not met its operational goal.
Roll out in small cohorts
Begin with a controlled cohort that represents key operating systems and network zones. Verify agent enrollment, time synchronisation, expected events, indexing, dashboard roles, alert delivery, and removal. Fix rules and labels before expanding.
For an illustrative server cohort, create one safe file change and one controlled login event, then show that an authorised analyst can find both while a viewer account cannot change rules or agent settings.
Deployment decisions
Record the evidence alongside the rollout plan.
| Area | Decision | Evidence |
|---|---|---|
| Endpoints | Which populations and exceptions are in scope? | Owner-approved inventory. |
| Enrollment | How are agents authenticated and retired? | Cohort enrollment and removal test. |
| Retention | Which event classes stay searchable and for how long? | Measured volume and query test. |
| Access | Who may administer, investigate, or export data? | Role test and network review. |
Practical questions
Can every endpoint use the same configuration?
Not necessarily. Operating systems, roles, network zones, and event volume vary. Use a common baseline plus documented profiles.
What proves enrollment is safe?
A named endpoint enrolls through the intended path, sends expected telemetry, and can be revoked without disrupting others.
What belongs in a recovery test?
Test the documented persistence boundary, dashboard and role access, and a representative search after restoration.
Plan, prove, operate
Inventory endpoints, use cases, architecture, certificates, access, storage, and owners.

Review storage, agent health, rule changes, access, backups, and version updates.
Handover checks
Keep operating evidence with the platform.
Cohort test
Representative endpoints have passed enrollment and telemetry checks.
Role review
Analyst and administrator paths are tested separately.
Retention record
Measured volume, search expectations, and storage ownership are documented.
