US Cybersecurity Firm Cribl Acquires Israeli Startup CardinalOps for $100 Million

American technology company Cribl announced on Tuesday its acquisition of Israeli startup CardinalOps, which specializes in Agentic Detection Engineering. Although the companies did not officially disclose the purchase price, it is estimated at around $100 million. Following the acquisition, CardinalOps employees will join Cribl, which plans to establish a development center in Israel and expand its workforce there.

Cribl develops telemetry management platforms for cybersecurity and IT teams and is considered one of the fastest-growing companies in the US, with annual recurring revenues exceeding $300 million. This acquisition will enable Cribl to expand into cybersecurity, offering customers alternatives to traditional SIEM solutions, thereby reducing security data management costs and enhancing threat coverage.

CardinalOps, founded in 2020 by serial entrepreneurs Michael Momchoglu (CEO) and Yair Manor (CTO), employs about 25 people, mostly in Israel. The company has raised approximately $40 million from investors including Viola Ventures, Glilot Capital, Battery Ventures, and others. CardinalOps uses artificial intelligence to help organizations continuously assess and improve their threat coverage by mapping security controls against real-world attacker techniques. Its technology automates detection engineering tasks, helping security teams identify coverage gaps, fix broken or noisy rules, and optimize existing security capabilities.

Cribl will integrate CardinalOps’ detection layer to rapidly convert raw data into actionable insights, improving protection levels. Cribl co-founder and CEO Clint Sharp emphasized that security teams need better ways to turn telemetry into effective detection rather than more disconnected tools. Michael Momchoglu highlighted that many security teams have quality data and tools but lack confidence in their protection, and joining Cribl will help build a SIEM alternative focused on paying for better protection, not data volume.

The decision to maintain and grow Cribl’s cybersecurity operations in Israel underscores the company’s recognition of local talent and the strategic importance of the Israeli tech ecosystem.
