Databricks has been on a quiet march toward becoming the infrastructure layer for enterprise AI for years — data lakes, MLflow, Delta Lake, Unity Catalog. Today at RSAC 2026, the company took its most surprising market move yet: entering enterprise cybersecurity with the announcement of Lakewatch, an open agentic SIEM.

What Is Lakewatch?

SIEM stands for Security Information and Event Management — the category of tools that ingest security telemetry, correlate it, generate alerts, and support incident response. Splunk has dominated this category for years; SentinelOne, Microsoft Sentinel, and Elastic Security are the major challengers.

Databricks is entering with a distinctly different architectural thesis: what if your SIEM was built on the same open data infrastructure as the rest of your enterprise data, with AI agents running the detection and response layer?

Lakewatch is positioned as an open agentic SIEM with three core differentiators:

1. Open Data Foundation

Lakewatch is built on Databricks’ open stack — Delta Lake for storage, MLflow for model management, Unity Catalog for governance. Security telemetry lives alongside business and operational data rather than in a siloed, proprietary data store. This means analysts can correlate security events with business context — something traditional SIEMs make painful.

2. Unified Telemetry

Traditional SIEMs primarily ingest security logs. Lakewatch is designed to ingest and correlate security, IT, and business telemetry in a unified stream. An unusual login pattern is more meaningful when you can correlate it against HR records, financial system access, and recent procurement activity — context that’s in your data lake but not in your SIEM today.

3. Agentic Detection and Response

This is the RSAC announcement angle: Lakewatch uses AI agents to automate threat detection and response workflows, not just to surface alerts for human analysts. Agents can:

  • Investigate alert chains autonomously
  • Query additional context from connected data sources
  • Draft incident reports
  • Trigger response playbooks
  • Escalate to human analysts with pre-gathered context

The “open” framing is precise — Lakewatch is built on open foundations, but Databricks has not described it as fully open-source. Think of it as the same model as Databricks’ other products: open standards and open integrations, with proprietary orchestration and management layers.

The CNBC IPO Subtext

CNBC’s coverage of the Lakewatch announcement included a notable aside: the security market entry positions Databricks favorably ahead of a potential IPO. Enterprise security is a high-margin, high-retention revenue category, and Databricks’ existing customer relationships in financial services, healthcare, and enterprise tech give it a credible distribution path for a security product without cold-start sales challenges.

Whether or not an IPO materializes in 2026, the Lakewatch announcement signals that Databricks is expanding its total addressable market aggressively before any public market event.

Why This Matters for Practitioners

If you’re a security engineer or CISO evaluating your SIEM stack, Lakewatch is worth tracking — but with appropriate patience. The RSAC announcement means it’s not yet generally available. Key questions to evaluate when it ships:

  • Detection quality: The core SIEM value is alert fidelity, not just data ingestion. How does Lakewatch’s agentic detection layer perform on false positive rates compared to Splunk ES or SentinelOne?
  • Migration path: Moving a mature SIEM is expensive. What’s the Lakewatch path for organizations with years of Splunk queries and playbooks?
  • Agentic response guardrails: Automated response is powerful and potentially risky. What oversight and approval mechanisms exist before an agent takes action?

For organizations already running Databricks as their data platform, Lakewatch is a compelling prospect — the integration story is obvious, and the shared data layer removes a major SIEM deployment friction point.
