Deploy Free. Own Everything. Scale Without Limits. Expert engineering for OpenSearch — the fully open-source search, analytics, and security platform. No licensing fees, no vendor lock-in, full control of your data and infrastructure.
OpenSearch is maintained by AWS and a broad community under the Apache 2.0 licence. No proprietary features locked behind paid tiers, no licence audits, no sudden pricing changes. What you deploy is what you own.
Ideal for UK, European, and GCC regulated environments — deploy entirely on-premises or in a private cloud with no mandatory external connectivity. Meets GDPR, UK/EU NIS2, NCA, SAMA, and Qatar PDPL data localisation requirements without architectural compromise.
OpenSearch ships with TLS encryption, role-based access control, audit logging, field- and document-level security, and single sign-on (SAML/OIDC) — features that require a paid tier in competing platforms.
OpenSearch is not a niche fork — it is actively developed by AWS, Red Hat, SAP, and a large contributor community. Production-grade releases ship regularly with security patches, new ML features, and performance improvements.
Deploy and configure OpenSearch Security Analytics for SIEM use cases — detection rules, log correlation, alert triage workflows, and dashboards. MITRE ATT&CK-aligned detections built from day one.
35–65% false-positive reduction, 20–30% faster triageCentralise logs, traces, and metrics in OpenSearch Observability. Build SLO-driven dashboards in OpenSearch Dashboards, configure alerting pipelines, and accelerate RCA with correlated telemetry.
20–40% lower MTTR, unified observability without SaaS costDesign and implement hot/warm/cold tiering with ISM policies, shard allocation strategy, index template standardisation, query tuning, and capacity planning for predictable long-term growth.
25–55% faster search, 30–70% lower storage costOngoing engineering support — monthly ISM policy reviews, detection rule tuning, index health monitoring, version upgrade planning, and capacity management. Keeps your cluster lean and performant over time.
QoQ cost down 10–15%, cluster incidents reduced 20–30%Moving from Elasticsearch, Splunk, or another platform to OpenSearch? HIT engineers the migration end-to-end — reindexing, pipeline conversion, detection porting, and rollback planning — with zero data loss and minimal downtime.
Inventory existing log sources, index volumes, retention requirements, and detection content. Model the TCO delta between your current platform and OpenSearch — including infrastructure, support, and engineering costs.
Outcome: Validated business case and phased migration roadmapReference architecture for self-managed bare-metal, VM, Kubernetes, or AWS OpenSearch Service. Design hot/warm/cold ISM tiers, HA/DR topology, network security zones, and RBAC model before a single byte is migrated.
Outcome: Production-grade architecture with documented capacity modelConvert Logstash, Beats, Fluentd, or OpenTelemetry pipelines to target OpenSearch ingest. Remap index templates, apply field normalisation, and validate data quality before cutover.
Outcome: Consistent schema and verified data fidelity across all sourcesPort Sigma rules, Elastic KQL rules, or legacy SIEM correlation logic into OpenSearch Security Analytics detection format. Validate parity and tune thresholds against your actual log baseline.
Outcome: Detection coverage maintained or improved post-migrationRecreate key operational dashboards in OpenSearch Dashboards with improved layout and drill-down capability. Configure alerting monitors, notification channels, and escalation workflows.
Outcome: Full operational visibility from day one post-cutoverDual-run period to validate parity, benchmark ingest TPS and query latency, tune ISM policies and shard allocation, then execute controlled cutover. Full runbooks and knowledge transfer delivered at close.
