SIEM-as-a-Service offering leverages Elastic for unified cybersecurity across the US government

SIEMaaS reflects CISA’s commitment to protecting federal assets and driving a collaborative, standardized approach to national cybersecurity and resilience.

The service is available to FCEBs at no cost and offers flexibility; agencies may continue to operate their own SOC using the CISA-hosted platform. CISA’s Continuous Diagnostics and Mitigation (CDM) Program Management Office (PMO) will oversee hosting and operations for SIEMaaS, including infrastructure, data pipelines, enrichment workflows, and threat detection engines. Elastic was awarded this contract through prime contractor ECS — an advanced technology provider specializing in data, AI, cybersecurity, and enterprise transformation.

SIEMaaS expands on Elastic’s longstanding leadership in the security industry, offering highly scalable, cost-efficient solutions built on an open standards architecture. It also builds upon Elastic’s partnerships with CISA and GSA’s OneGov initiative, which provides bespoke government pricing for FCEBs.

A large FCEB has already committed to be the first tenant of SIEMaaS. This initial deployment will serve as the operational blueprint for future rollouts across government, accelerating time-to-protection and establishing a repeatable, cost-efficient model for shared national cyber defense.

As cyber threats grow more sophisticated, especially those driven by AI, agencies must strengthen their defenses while ensuring effective stewardship of taxpayer resources. SIEMaaS enables them to do both.

Key benefits include:

• Zero cost to agencies and increased operational efficiency: CISA fully funds the SIEMaaS platform, allowing agencies to reallocate existing SIEM and logging budgets to other mission-critical needs.

• Hands-off infrastructure operations: CISA manages all Elastic Cloud-hosted environments, including deployment, sizing, configuration, and ongoing monitoring — eliminating infrastructure management responsibilities for agencies.

• Next-generation SIEM capabilities: Elastic’s SIEM delivers advanced investigative power through capabilities like Attack Discovery, Elasticsearch Query Language (ES|QL), and cross-cluster search (CCS). Analysts can correlate events and investigate incidents without manually aggregating data or switching tools, accelerating detection, response, and forensics.

• Standardization and efficiency across government: SIEMaaS provides standardized data collection informed by open standards protocols. It also delivers planned curated threat intelligence feeds and consistent detection analytics across federal agencies capabilities.

• AI-driven cyber defense: Elastic brings agentic AI directly into the SOC by triaging threats, enriching alerts, leveraging retrieval augmented generation (RAG) for investigations, powering natural-language threat hunting, and automating integrations and workflows.

• Streamlined migration from legacy SIEM tools: CISA supports migration from legacy SIEM environments using a repeatable, proven approach. Professional services and automated AI-powered tools help agencies migrate dashboards, rules, and detections seamlessly into Elastic.

• Free training and workshops: Agencies receive complimentary training, onboarding support, and workshops to ensure teams can fully operationalize SIEMaaS from day one.
