AI SOC Analyst for Automated Alert Investigation

Culminate Security develops automated cybersecurity operations technology designed to streamline and modernize Security Operations Center (SOC) workflows.

The company’s platform centers on autonomous alert investigation, reducing the manual labor required to sort through large volumes of low-priority or noisy alerts that overwhelm traditional monitoring systems. By applying machine learning to dynamically prioritize alerts, Culminate identifies high-risk indicators such as credential misuse, persistence mechanisms, suspicious communication patterns, and stealthy exfiltration attempts hidden within routine system activity.

Culminate’s system correlates telemetry across disparate data sources — including EDR logs, email security events, and identity system records — to detect nuanced behavioral anomalies that conventional rule-based approaches often miss. Culminate also addresses gaps left by legacy SOAR tools by analyzing contextual clues in investigations, such as embedded malicious links hosted on trusted cloud platforms like OneDrive or Power BI. This enables the platform to uncover modern attack patterns, including supply chain-style compromises and malicious activity conducted through legitimate services.

According to the personal LinkedIn page of co-founder and CEO Rex Guo, Culminate has been acquired, but the acquiring company remains a mystery. At the time of publication, visitors of Culminate’s website are met with a “Page not found” note that explains: “The page you are looking for doesn’t exist or has been moved.”
