Elastic Agentic SOC Framework: Benchmarking LLMs for Security Workflows

As we navigate through 2026, the integration of Large Language Models (LLMs) into Security Operations Centers (SOCs) has shifted from experimental pilots to critical infrastructure. However, a significant challenge remains: generic public leaderboards are poor indicators of an LLM's reliability in high-stakes security environments. Elastic Security Labs has released a new evaluation framework designed specifically to grade models on actual security workflows, moving beyond static knowledge tests to assess "Agentic" capabilities—specifically the ability to execute tools, analyze traces, and assist in attack discovery.

Introduction

Defenders can no longer afford to trust models based solely on their ability to code or converse. In an Agentic SOC, the LLM must act as an operator, not just a scribe. Elastic's new benchmark addresses the "trust gap" by evaluating models on their performance in Agent Builder, Attack Discovery, and automatic migration scenarios. This framework is essential for SOC managers and CISOs who need to validate that an AI investment will actually reduce Mean Time to Detect (MTTD) and Mean Time to Respond (MTTR) without introducing operational risk or hallucinations.

Technical Analysis

The Elastic benchmarking framework departs from traditional NLP evaluations by focusing on tool-use capabilities and execution fidelity. The technical evaluation rests on three core pillars relevant to modern SOCs:

Tool Calls and Execution Traces: The framework does not merely check if the model knows a command; it verifies if the model can successfully invoke API endpoints, execute queries, and interpret the results within a multi-step reasoning chain. This simulates real-world tasks like isolating an endpoint or fetching specific logs.
Blind Judging: To eliminate bias, the evaluation utilizes a blind scoring mechanism. Outputs are graded based on the correctness of the security action (e.g., correctly identifying a malicious process) without the evaluator knowing which LLM generated the response. This ensures the benchmark reflects genuine defensive utility rather than brand reputation.
Agentic Components: The grading is specific to Elastic's Agentic SOC features:
- Agent Builder: Evaluates the model's ability to generate and debug security automation workflows.
- Attack Discovery: Tests the model's proficiency in correlating alerts to identify ongoing compromises.
- Automatic Migration: Assesses the model's capability to translate and update security queries and rules across different data versions or schema changes automatically.

This approach shifts the security metric from "textual accuracy" to "operational success rate," ensuring that the LLM can reliably navigate the complex, interconnected systems of a modern SOC.

Executive Takeaways

Prioritize Tool-Use Proficiency over Chat Accuracy: Stop evaluating models based on generic coding or conversational benchmarks. Your SOC requires models that can reliably execute API calls and navigate tool chains without failure.
Demand Execution Trace Transparency: Do not accept AI outputs as "black boxes." Require your AI tools to provide full execution traces so analysts can audit the decision-making path and verify compliance with standard operating procedures (SOPs).
Implement Blind Evaluation Internally: When selecting LLMs for your security stack, run blind tests. Have senior analysts grade the outputs without knowing the vendor or model version to eliminate confirmation bias.
Validate Automatic Migration Logic: Before allowing an LLM to handle automatic migrations of rules or queries, establish a rigorous testing sandbox. A failure in "automatic migration" can result in blind spots in your detection coverage.
Isolate Agent Builder Deployments: While "Agent Builder" capabilities accelerate automation, they also increase the risk of runaway loops. Initial deployments should be strictly confined to non-production environments with human-in-the-loop (HITL) oversight.

Remediation & Implementation

To operationalize the insights from Elastic's benchmarking framework, security teams should take the following steps:

Review Elastic Security Labs Guidance: Access the full report at the Elastic Security Labs URL to understand the specific grading criteria.
Update Evaluation Criteria: Revise your RFPs and internal proof-of-concept (PoC) scripts to include specific tests for "Tool Calling" success rates and "Attack Discovery" precision, rather than generic MMLU scores.
Establish a "Blind Grading" Protocol: Create a workflow where vendor AI outputs are anonymized and graded by your internal Tier 3 analysts before procurement decisions are made.
Audit AI-Generated Automations: For any workflows created via "Agent Builder" tools, implement a mandatory peer-review process to validate logic before promotion to production.
