TLDR: CrowdStrike has announced the acquisition of Madrid-based data observability startup Onum for $290 million. The strategic move aims to significantly boost CrowdStrike’s AI-native security capabilities and its Falcon Next-Gen SIEM platform by integrating Onum’s real-time telemetry processing technology. This acquisition is a direct response to the increasing threat of AI-driven cyberattacks and underscores CrowdStrike’s commitment to leveraging artificial intelligence for advanced threat detection and cybersecurity.
CrowdStrike, a leader in cloud-delivered cybersecurity, has announced its acquisition of Onum, a Madrid-based data observability startup, for a reported $290 million. The deal, which was revealed on August 27, 2025, is a strategic maneuver designed to significantly bolster CrowdStrike’s AI-native security capabilities and enhance its Falcon Next-Gen SIEM (Security Information and Event Management) platform. This acquisition comes amidst an escalating landscape of AI-driven cyberattacks, highlighting CrowdStrike’s proactive approach to cybersecurity innovation.
Onum specializes in real-time pipeline detection, a critical technology that identifies anomalies in data as it flows into enterprise systems. Its technology is adept at transforming raw telemetry into enriched intelligence within milliseconds, a process that is crucial for accelerating threat detection, reducing storage expenses, and ultimately improving customer outcomes. The integration of Onum’s capabilities is expected to provide AI-driven defenses with more intelligent, rapid, and cost-effective telemetry within CrowdStrike’s Falcon platform.
CrowdStrike CEO George Kurtz emphasized the strategic importance of data in modern cybersecurity, stating that the company is evolving into ‘the Reddit of security data.’ This vision underscores the critical role of data aggregation and analysis in combating sophisticated cyber threats. The acquisition aligns perfectly with CrowdStrike’s broader strategy of leveraging artificial intelligence to continuously enhance its security offerings.
The acquisition process was notably swift, completed within three months. Kurtz revealed that CrowdStrike had temporarily paused its deal-making activities following a global IT outage in 2023. However, the company maintained an active mergers and acquisitions pipeline, engaging with various startups, venture capital firms, and entrepreneurs, which ultimately led to the Onum acquisition. Since 2017, CrowdStrike has acquired eight companies, including Humio for $400 million in 2021 and Flow Security for an estimated $200 million in 2024. Kurtz also drew a distinction between CrowdStrike’s targeted acquisition strategy and the larger deals pursued by competitors, such as Palo Alto Networks’ $25 billion acquisition of CyberArk or Google’s proposed $32 billion acquisition of Wiz.

Onum, founded in 2022, had successfully raised nearly $42 million before its acquisition and was backed by prominent firms like Dawn Capital and Insight Partners. The deal reflects a broader trend in the cybersecurity market, which is projected to grow from $76 billion to nearly $100 billion by 2025, creating intense pressure for companies to acquire specialized capabilities rather than developing them internally.
