ClickHouseの速度で実現するインテリジェントセキュリティ:Cogent SecurityがAIネイティブな脆弱性管理プラットフォームを構築した方法

Cogent Security leverages ClickHouse to deliver billions of security detections in sub-second timeframes, supporting its AI-native vulnerability management platform. Transitioning from Postgres to ClickHouse reduced P90 query latency from 5 seconds to under 1 second for over 100 million rows. Cogent's Chart Agent, using an agentic loop architecture with ClickHouse projections, improved accuracy from 40% to 94%. As AI accelerates software vulnerability exploitation, enterprise security teams struggle with complex, often ineffective point solutions. Cogent aims to keep companies abreast of rapidly evolving threats, emphasizing that handling millions of detections requires significant organizational context and understanding of affected systems. The platform's efficiency has been highlighted by the reduction in average time-to-exploit from 2.3 years in 2018 to just 1.6 days by 2026. By addressing the chronic manpower shortages in security teams, Cogent's infrastructure, built on an efficient data pipeline and ClickHouse-driven serving layer, facilitates swift, accurate responses to vulnerabilities, offering a unified view of the security landscape. The company's Ontology Service ensures consistent data model semantics, aiding the agent's understanding of unique customer environments. The speed of ClickHouse is central to Cogent's success, enabling iterative agent loops and rapid evaluation cycles that enhance tool precision and adaptability, crucial for combating AI-accelerated threats.
