Guided Demo

Find the threats lurking in your data

Security starts with data — and data is what we know best. As the company behind Elasticsearch, the world's leading open source search and analytics engine, our SIEM brings powerful, AI-driven detection and investigation to all your security data, at any scale.

DIFFERENTIATORS

Defend without limits

Defend your entire attack surface — across any cloud, endpoint, or on-prem system — with a SIEM that scales with you.

  • FEDERATED SEARCH

    Ingest everything, search anything

    Bring in every log, alert, and event — even from third-party sources — at petabyte scale. Investigate across clouds, regions, and on-prem clusters with a single query, and turn siloed data into a live, actionable search lake.

  • CONTEXTUAL AI

    AI that knows your world

    The only SIEM that grounds AI with your data — past incidents, playbooks, configurations, and threat intel. Elastic powers accurate investigations with retrieval augmented generation (RAG) without sending context to third parties.

  • OPEN SOURCE LEADER

    The most deployed open source SIEM

    Built on the world's most popular open source search platform, Elasticsearch. Enjoy open access to engineering teams, product leaders, researchers, and other users directly in the community Slack and GitHub.

  • ALL INCLUSIVE

    XDR and SIEM in one platform

    Protect your ecosystem with an open and extensible all-in-one solution — SIEM, XDR, and cloud security on a single stack. Investigate threats without hopping between products or paying twice.

  • FLEXIBLE HYBRID DEPLOYMENT

    Deploy on cloud, on-prem, or both

    Run on-prem, on cloud (with AWS, Azure, or GCP), or in hybrid environments. Unlike cloud-only providers, Elastic treats on-prem users as first-class citizens, with full SIEM capabilities even in air-gapped or DIL environments.

  • AFFORDABLE STORAGE

    Stretch your storage, not your costs

    Elastic SIEM lets you store and search years of high-fidelity data on cost-effective tiers using searchable snapshots. Investigate threats with full context, without gaps from sampling or aggregation, and without waiting to rehydrate archived data.
