Open XDR vs Native XDR 2026 - Architecture, Cost, and Which Approach Fits Your Stack
The XDR market is split between two fundamentally different approaches. Native XDR replaces your existing security tools with a single vendor's integrated platform. Open XDR keeps your existing tools and adds a correlation layer on top. The choice affects your cost structure, vendor flexibility, detection depth, and operational complexity.
Native XDR costs approximately $80-$180 per endpoint per year and replaces 3-6 existing tools. Open XDR costs approximately $40-$80 per endpoint per year for the correlation layer, but you continue paying for your existing tools. The total cost depends entirely on your current tool investments and contract commitments.
Native XDR
Single vendor provides endpoint, cloud, email, identity, and network protection in one integrated platform. All telemetry flows through one data pipeline with pre-built correlation rules. You replace existing tools with the vendor's unified solution.
Named Vendors
- CrowdStrike Falcon
- Palo Alto Cortex XDR
- Microsoft Defender XDR
- SentinelOne Singularity
- Trend Micro Vision One
- Cisco XDR
Open XDR
Vendor-agnostic platform that integrates with your existing security tools through APIs and data connectors. Provides correlation and investigation across all tool telemetry without requiring tool replacement. You keep your best-of-breed tools and add a correlation layer.
Named Vendors
- Stellar Cyber (Open XDR platform)
- Elastic Security (resource-based pricing)
- ReliaQuest GreyMatter (SIEM/XDR hybrid)
- Exabeam (behavioral analytics)
- Hunters (cloud-native SOC platform)
Cost Comparison Scenario: 500 Endpoints, 5 Existing Tools
Consider an organisation with 500 endpoints currently running CrowdStrike Falcon Pro (EDR), Proofpoint (email), Wiz (CSPM), Darktrace (NDR), and CrowdStrike Identity Protection. They want XDR-level correlation across all these sources.
Native XDR Approach
Replace all 5 tools with CrowdStrike Falcon Elite (or equivalent)
Open XDR Approach
Keep all 5 tools, add Stellar Cyber or Elastic for correlation
In this scenario, native XDR is more expensive in year 1 (due to migration and cancellation costs) but cheaper in year 2+ because it eliminates 4 of the 5 existing tool licenses. Open XDR avoids migration disruption but has higher ongoing costs. Break-even typically occurs in year 2-3.
Native XDR Is Cheaper When...
- Greenfield deployment (no existing tools to replace)
- Existing tool contracts are expiring (no cancellation fees)
- Single-vendor environment is acceptable to your risk tolerance
- You want the simplest operational model with one console
- Long-term cost optimization is prioritized over short-term disruption
Open XDR Is Cheaper When...
- Significant existing tool investments with multi-year contracts
- Multi-vendor strategy is a governance requirement
- Niche or industry-specific tools must be retained
- Very high endpoint counts where resource-based pricing (Elastic) saves money
- Avoiding vendor lock-in is a strategic priority
Elastic Security: The Resource-Based Alternative
Elastic Security eliminated per-endpoint pricing entirely in March 2026, moving to a resource-based model where you pay for compute and storage rather than per agent. This is a significant shift that makes Elastic particularly attractive for organisations with high endpoint counts, as the cost scales with data processing needs rather than linearly with device count.
A 10,000-endpoint organisation might pay the same as a 5,000-endpoint organisation if their data volumes and processing requirements are similar. This breaks the linear cost curve that makes native XDR expensive at scale. Elastic's open architecture also supports extensive third-party integrations, making it a strong open XDR option.
The trade-off is operational complexity. Elastic Security requires more configuration, tuning, and infrastructure management than native XDR platforms like CrowdStrike or Microsoft Defender. It is best suited for organisations with experienced security engineers who can build and maintain detection content. For security teams wanting a turnkey solution, native XDR remains the better choice despite higher per-endpoint costs.
Frequently Asked Questions
What is the difference between open XDR and native XDR?
Native XDR is a single vendor's integrated security platform that replaces your existing tools with one unified solution. CrowdStrike Falcon, Palo Alto Cortex XDR, and Microsoft Defender XDR are native XDR platforms. Open XDR is a vendor-agnostic correlation layer that integrates with your existing third-party security tools without requiring you to replace them. Stellar Cyber, Elastic Security, and ReliaQuest GreyMatter are open XDR platforms. The fundamental difference is whether you consolidate to one vendor or keep your existing multi-vendor stack.
Is open XDR cheaper than native XDR?
Open XDR has lower per-endpoint correlation costs (approximately $40-80 per endpoint per year for the XDR layer) but you continue paying for all your existing security tools. Native XDR costs $80-180 per endpoint per year but replaces 3-6 existing tools, eliminating those license costs. For a greenfield deployment, native XDR is typically cheaper. For environments with significant existing tool investments and multi-year contracts, open XDR can be cheaper in the short term by avoiding early termination fees and retraining costs.
Which vendors are native XDR vs open XDR?
Native XDR vendors include CrowdStrike Falcon (endpoints, cloud, identity), Palo Alto Cortex XDR (endpoints, network, cloud), Microsoft Defender XDR (endpoints, email, identity, cloud apps), SentinelOne Singularity (endpoints, cloud, identity), Trend Micro Vision One (endpoints, email, cloud, network), and Cisco XDR (endpoints, network, email). Open XDR vendors include Stellar Cyber (multi-vendor correlation), Elastic Security (resource-based, open architecture), ReliaQuest GreyMatter (SIEM/XDR hybrid), and Exabeam (behavioral analytics-driven). Elastic Security notably eliminated per-endpoint pricing in March 2026.
When should I choose open XDR over native XDR?
Choose open XDR when you have significant existing investments in best-of-breed security tools that you cannot or do not want to replace, when vendor lock-in is a primary concern for your organisation, when you need to integrate niche or industry-specific security tools that native XDR vendors do not support, or when your data ingestion volumes are very high and resource-based pricing (like Elastic) is cheaper than per-endpoint pricing. Open XDR is also better when you have a multi-vendor environment by design and want the flexibility to swap individual components without changing your XDR platform.
What is Elastic Security's new pricing model?
In March 2026, Elastic Security eliminated per-endpoint pricing entirely and moved to a resource-based model. You pay for compute and storage resources rather than per agent or per device. This is significant for organisations with high endpoint counts because the cost scales with data volume and processing needs rather than linearly with device count. A 10,000-endpoint organisation might pay the same as a 1,000-endpoint organisation if their data volumes are similar. This model makes Elastic Security particularly attractive for large-scale deployments.
