Is your SIEM actually ready? A new way to find out

Talk to any security operations center (SOC) manager about how they track operational readiness, and you'll probably hear some version of the same story.

Coverage tracking lives in a spreadsheet; someone maybe updates it quarterly. Pipeline health gets checked when something breaks. Retention policies were set during initial deployment and haven't been reviewed since. Detection engineers enable rules based on what's available in the rule library without a clear view of whether the required data sources are actually present.

Every team is answering pieces of the readiness question in isolation with different tools on different timelines. The SOC manager has a coverage matrix. The platform engineer monitors ingest rates. The compliance manager collects retention evidence manually before each audit. Nobody has the full picture, and the full picture is what matters.

SIEM Readiness is a new capability in Elastic Security, available in technical preview as of 9.4, that provides a centralized, continuously updated, and actionable view of your SIEM's operational health.

We're starting with Visibility Health because before you can evaluate whether your detections are effective or your response workflows are operational, you need to know whether the underlying data is even there, correct, flowing, and retained. Visibility is the prerequisite for everything else.

The readiness view is organized around five log categories that represent the core telemetry domains for a modern SOC:

• Endpoint/Host: Process, file, registry, and system-level events

• Identity: Authentication, access management, and directory services

• Network: Firewall, DNS, proxy, and flow data

• Cloud: Cloud provider APIs, configuration, and activity logs

• Application/SaaS: Business application and SaaS platform events

Within each category, SIEM Readiness evaluates four dimensions of health.

1. Coverage

2. Quality 

3. Continuity

4. Retention

This is the most fundamental question, and it works at two levels.

• At the rule level: SIEM Readiness checks every enabled detection rule against the data sources it depends on. If you've enabled a set of Initial Access rules that require CloudTrail, but CloudTrail isn't flowing into your environment, those rules are enabled in name only. They'll never fire. SIEM Readiness surfaces that gap not just as "CloudTrail is missing," but as "CloudTrail is missing and 23 of your enabled rules across 6 MITRE ATT&CK tactics depend on it."

That context changes how you prioritize. You're not onboarding data sources alphabetically. You're onboarding the one that closes the most detection gaps.

• At the category level: SIEM Readiness evaluates your overall coverage across the five log categories against baselines derived from MITRE ATT&CK, NIST CSF, and CIS benchmarks. But it's environment-aware — if you have no cloud infrastructure, cloud coverage isn't counted against you. Your readiness score reflects your environment, not a generic ideal.

Visibility Health is the foundation. It answers: Can your SIEM detect threats given the data it has?

But readiness is a broader question, and we're building toward answering all of it.

Detection Readiness is the next horizon. Beyond "do you have the data?" lies "are your detections actually effective?" Which enabled rules have never fired — are they misconfigured, or is your environment genuinely clean? Which MITRE ATT&CK tactics have strong rule coverage backed by healthy data, and which have gaps? Given your environment, which prebuilt rules should you enable but haven't? Detection Readiness will turn rule management from a library browsing exercise into a guided, coverage-driven workflow.

Response Readiness will follow. Are your response workflows operational? How quickly are alerts triaged and cases resolved? Are your connectors to ticketing and SOAR platforms healthy? Which alert types have automated response actions, and which still require an analyst to manually intervene every time? Response Readiness will close the loop from data through detection to action.

Together, these three layers answer the full question:

• Visibility — Can you detect? (Do you have the right data?)

• Detection — Will you detect? (Are your rules effective?)

• Response — Will you act in time? (Are your workflows operational?)

We're also exploring AI-assisted readiness insights — lightweight summarization that surfaces the top risks and suggests prioritized next steps. Think: "Your Identity coverage is strong, but 18% of your enabled rules lack supporting data. Onboarding CloudTrail would restore Initial Access coverage across 23 rules." It’s not auto-remediation, but clear, prioritized guidance when you need it.

We're releasing SIEM Readiness because we believe the question "Is my SIEM ready?" deserves a clear, continuous, product-native answer — not a spreadsheet, not a quarterly audit scramble, and not a vector search pipeline you had to build yourself.

We started with Visibility Health because it's the foundation everything else depends on. Detection Readiness and Response Readiness are coming next.

But the teams who'll use this every day know best what it needs to be. We want to hear from you:

• What do you check manually today that should be automatic?

• What questions do you wish your SIEM could answer about its own operational health?

• What would make this feature the first page you open every morning?

Join the conversation:

• Comment directly on the roadmap in GitHub: SIEM Readiness Roadmap Issue.

• Reach out to your Elastic team if you want a deeper design partner conversation; we'd love to talk.

The most dangerous SIEM is the one that looks fine. Let's make sure yours actually is.
