Intruder

Intruder is a cloud-based vulnerability scanner and attack surface management platform that continuously monitors internet-facing systems and cloud infrastructure to identify security weaknesses before exploitation. The platform provides real-time discovery and prioritization of attack surface issues, automatically discovering new services exposed to the internet and initiating vulnerability scans whenever changes are detected to minimize the exposure window for newly introduced risks. Intruder combines multiple industry-leading scanning engines with proprietary intelligence to detect over 1,000 attack surface issues that other scanners miss, with emerging threat scans checking systems for the latest vulnerabilities within hours of public disclosure.

The platform integrates threat intelligence including CISA Known Exploited Vulnerabilities (KEV) list and EPSS (Exploit Prediction Scoring System) scores powered by machine learning to prioritize vulnerabilities based on actual exploitation likelihood rather than generic severity scores. Intruder performs comprehensive security testing across network infrastructure, web applications, and cloud environments (AWS, Azure, Google Cloud), covering network misconfigurations, application vulnerabilities (SQL injection, XSS, authentication flaws), cloud security issues, SSL/TLS problems, and compliance violations. The platform provides detailed remediation guidance with step-by-step instructions in concise, actionable formats without the noise and false positives common in traditional vulnerability scanners, making it accessible for teams without deep security expertise.

Trusted by MSSPs, SMBs, and enterprises across finance, healthcare, technology, and government sectors, Intruder offers extensive integrations with SIEM platforms, ticketing systems (Jira, ServiceNow), and collaboration tools (Slack, Microsoft Teams). The platform supports both external scanning for internet-facing assets and internal scanning for corporate networks, with scheduled scans, on-demand assessments, and continuous monitoring to maintain security posture as infrastructure evolves. Intruder provides compliance support for ISO 27001, SOC 2, PCI DSS, and other regulatory frameworks through comprehensive scanning and reporting capabilities.
