SentinelOne Acquires Observo AI to Boost SIEM and Security Ops

SentinelOne has made a strategic move to acquire Observo AI, a decision poised to significantly enhance its AI SIEM and data offerings. This acquisition arrives at a time when security operations teams face mounting pressure from escalating data volumes, rising costs, and operational complexity. By integrating Observo’s advanced capabilities, SentinelOne aims to deliver a more open, intelligent, and autonomous security operations framework, enabling organizations to process and act on security data with unprecedented speed and efficiency.

The growing challenge for modern security teams lies in managing vast amounts of telemetry without sacrificing visibility or responsiveness. Many existing data platforms were designed before the era of AI-driven security operations, leaving them ill-equipped to handle today’s dynamic threat landscape. Observo addresses this gap with an AI-native, real-time telemetry pipeline that processes data before it reaches a SIEM or data lake. This approach allows for substantial cost reductions, improved threat detection, and accelerated response times.

According to Tomer Weingarten, CEO of SentinelOne, “Security is fundamentally a data challenge. Older, rules-based systems simply can’t keep up with the scale and sophistication of modern attacks. Observo’s architecture is open by design, intelligent by default, and built for autonomous operations. This acquisition allows us to offer customers greater flexibility, value, and choice in how they manage and route their data.”

Enterprises today generate enormous quantities of security and observability data across endpoints, cloud environments, identity systems, and generative AI applications. Traditional SIEM solutions often struggle under the weight of rigid pipelines, high storage expenses, and siloed data formats. With Observo, SentinelOne introduces a modern alternative, a policy-driven, adaptive data pipeline optimized for the autonomous SOC.

Customers gain significant advantages, such as faster threat resolution, substantial cost reductions, and more efficient security operations across varied environments. These benefits stem from several fundamental features: the freedom to integrate any system, anywhere. Observo supports open standards like OCSF, JSON, OTLP, and Parquet, allowing effortless ingestion and routing of telemetry to SIEMs, data lakes, or cloud platforms, all without becoming dependent on a single vendor.

This acquisition builds on SentinelOne’s existing investments in hyperscale data infrastructure within its Singularity Platform. Observo’s technology will enhance these foundations with intelligent, policy-driven data processing that occurs before storage or analysis. The result is an end-to-end architecture capable of ingesting data from any source, enriching it in transit, and storing it with full fidelity, enabling faster insights, reduced costs, and greater control throughout the security data lifecycle.

Looking ahead, this integrated approach paves the way for agentic AI workflows, where autonomous systems use enriched real-time data to detect and respond to threats with human-like reasoning at machine speed.

Gurjeet Arora, CEO of Observo AI, emphasized the significance of the merger: “Observo was created to help security and DevOps teams tackle massive data challenges in defending expanding attack surfaces. Combining our AI-native pipeline with SentinelOne’s leading cybersecurity platform represents a major advancement for customers and offers our team an incredible opportunity to collaborate with a global network of innovators. Together, we are positioned to define the future of autonomous security.”
