BigData Boutique is the first accredited support provider in the OpenSearch Software Foundation's new Long-Term Support program, delivering Foundation-approved enterprise support with 18-month lifecycles, rapid CVE response, and vendor-neutral stability.

[Prague, April 16, 2026 - OpenSearchCon Europe] - BigData Boutique is the first accredited support provider in the OpenSearch Software Foundation's new Long-Term Support (LTS) program, announced today at OpenSearchCon Europe. The LTS program introduces defined 18-month support lifecycles, SBOM-backed security compliance, and a formal vendor accreditation model - giving enterprises a clear path to production-grade OpenSearch support without vendor lock-in.

What the LTS Program Delivers

The OpenSearch Software Foundation designed the LTS program to address a gap that production operators have felt for years: the need for predictable support lifecycles and consistent security response, backed by the Foundation itself rather than any single vendor.

The program guarantees:

  • 18-month minimum support for each designated LTS release, starting with OpenSearch 2.19 and 3.6
  • 60-day CVE remediation for medium and high severity vulnerabilities, with early security notifications for accredited providers
  • SBOM generation across all ~150 OpenSearch repositories, enabling enterprises to demonstrate provenance and security posture for compliance and audit requirements
  • Upstream-first development - all LTS fixes and improvements must be contributed back to the open source project, preventing fragmentation

"This approach reflects growing enterprise demand for open source infrastructure that combines flexibility with reliability, particularly as organizations deploy AI-driven and mission-critical workloads," said Bianca Lewis, Executive Director of the OpenSearch Software Foundation.

Why BigData Boutique

We've been delivering exactly this kind of production-grade OpenSearch support for years - long before the LTS program existed. Our OpenSearch Enterprise distribution already provides curated releases, rapid security patching, hardened configurations, and 24/7 expert support with contractual SLAs. We're the main contributors to the OpenSearch Kubernetes Operator, a General Member of the OpenSearch Software Foundation, and our founder Itamar Syn-Hershko is an official OpenSearch Ambassador.

The Foundation's accreditation formalizes what our customers already experience. It means that when you choose BigData Boutique for OpenSearch support, you're working with a provider that the Foundation itself has vetted and approved - not just a vendor claiming expertise.

"Enterprises running mission-critical and AI-driven workloads on OpenSearch need safety when running open source, something that is more than promises. They need proven operational excellence, fast and reliable CVE response, and continuous security patching they can trust. BigData Boutique has been doing exactly that for years, supporting many enterprise customers in production with our Enterprise Distribution of OpenSearch and true 24/7 expert support. The new LTS program is a major ecosystem milestone. It formalizes the standards we already uphold and puts the OpenSearch Software Foundation's stamp behind them, reinforcing our position as the trusted partner for running OpenSearch securely, reliably, and at scale."

What This Means for Our Customers

For organizations already running OpenSearch Enterprise, this is a direct upgrade. You now get:

  • Foundation-backed accreditation validating the support you already receive
  • Early security vulnerability notifications through the LTS program's accredited provider channel
  • Guaranteed LTS release coverage with defined support windows you can plan around
  • Compliance-ready SBOMs for every OpenSearch component in your stack

For organizations evaluating OpenSearch for production workloads, the LTS program removes one of the last remaining hesitations. You no longer need to choose between open source flexibility and enterprise-grade support guarantees. The Foundation's accreditation model ensures you can access professional support globally, from a vetted provider, without being locked into any single vendor's ecosystem.

OpenSearch 3.6: The First LTS Release

OpenSearch 3.6, also announced today, is the first designated LTS release. It ships with the OpenSearch Observability Stack for full-stack observability, the OpenSearch Relevance Agent for AI-powered search tuning, and OpenSearch Launchpad for simplified cluster management. As an accredited LTS provider, BigData Boutique will deliver full support for OpenSearch 3.6 throughout its LTS lifecycle.
