Port0

Port0 is a cybersecurity company that develops an AI-native Security Operations Center (SOC) platform designed to address alert fatigue, data fragmentation, and operational inefficiency in enterprise security teams. The core platform centers on three capabilities: - Signal ingestion and fusion: Port0 connects to existing security tools without requiring data re-ingestion or replacement. It queries data where it already lives — in SIEMs, cloud environments, and data lakes — and fuses signals into a unified graph. - Automated investigation: Every incoming alert is automatically triaged, scored, and enriched with context before reaching a human analyst. The platform correlates signals across identities, endpoints, cloud infrastructure, and network sources to reconstruct full attack narratives. - Response orchestration: Analysts can contain, isolate, and remediate threats with a single click, or configure the platform to act autonomously within defined guardrails. The platform's AI component is called Soc0, described as an AI analyst that watches connected signals, investigates alerts with cited evidence, and responds to natural language queries about the environment. Port0 integrates with a broad range of security tools including CrowdStrike, Microsoft Defender, SentinelOne, Palo Alto Networks, Okta, Splunk, Elastic, Wiz, Zscaler, Fortinet, Tenable, Qualys, Rapid7, AWS, and Google Cloud, among others. The platform targets enterprise security operations teams dealing with high alert volumes, scattered telemetry across multiple platforms, and the limitations of legacy SIEM-based workflows. Port0 positions itself as a fusion layer over an existing security stack rather than a replacement for individual tools.
