Intruder enables lean security teams to operate proactively with the visibility and impact typically associated with only the largest enterprises.
Intruder’s unified platform combines Attack Surface Management, Vulnerability Management, and Cloud Security, delivering a single consolidated view of exposure (such as vulnerabilities, exposed assets, cloud account misconfigurations, and other attack surface issues). Intruder provides automated attack surface management designed to continuously discover and reduce unnecessary external exposure.
With over 1,000 custom attack surface checks, the platform surfaces exposures that other tools often miss or dismiss as purely ‘informational’. By assigning risk ratings that consider exploitability and technical severity, the real risks rise to the top of the priority list. User experiences that provide unified views and combat alert fatigue is a significant differentiator. Intruder’s platform provides clear, simple methods to continuously monitor for unknown assets, exposed systems, and new cloud services, enabling security teams to identify and remove unnecessarily exposed assets before exploitation.
24/7 emerging threat monitoring and Rapid Response capability assesses customer exposure when issues like critical zero-days emerge by automatically scanning their environments and issuing clear advisories. Rather than relying on scheduled scan cycles, assessments are triggered when credible risk is identified without requiring customer action.This reduces time-to-awareness and accelerates remediation. Intruder enables teams to respond decisively (often within 24 hours of vulnerabilities emerging) without needing to track headlines, initiate scans, or conduct manual investigation.
AI-powered security analyst GregAI validates issues, provides step-by-step remediation advice, and summarizes vulnerabilities for leadership teams. GregAI has comprehensive access to users’ security data within the Intruder platform, thus supporting security workflows in ways that standalone AI tools can’t.
Strengthening security industry-wide rather than confining these capabilities to closed, proprietary systems is apparent through Intruder’s open-source tools. Intruder has released powerful free tools used by thousands of security professionals globally. Autoswagger automatically scans APIs to discover sensitive endpoints and check for authorization weaknesses , while cvemon provides real-time monitoring for trending CVEs. Intruder’s open-source tools remove barriers and support practitioners beyond its own customer base.
These approaches to exposure management have driven impressive momentum. Intruder has expanded in the mid-market, achieving 81% enterprise customer growth in 2025. Sophisticated attack surface management doesn’t require massive security teams or extensive stacks. They’ve made enterprise-grade security achievable for organizations of all sizes.
Intruder’s impact transcends traditional vendor relationships, and the startup is actively shaping how modern organizations defend themselves.
