About Intruder

Intruder sells a single platform for continuous scanning across infrastructure, apps and cloud environments. Intruder was founded in 2015 by Chris Wallis to help solve the information overload crisis in vulnerability management. Intruder Systems Ltd completed the AICPA Service Organization Control (SOC) 2 Type 2 audit. The Intruder portal runs as a SaaS environment with logical data separation between clients' datasets.[5]

Intruder runs emerging threat scans within hours of new critical vulnerabilities going public. Intruder checks systems for 170,000+ infrastructure weaknesses, 75+ web-layer security issues and other misconfigurations. Intruder emerging threat scans check systems for newly discovered vulnerabilities automatically, as soon as a check is available. Intruder is powered by scanners including Tenable, Nuclei, OpenVas, and ZAP. Intruder offers internal target scanning only on the Pro and Enterprise plans.[6][7]

Intruder describes attack surface management as the continuous process of discovering, assessing, and reducing every digital asset an attacker can reach, including systems that are unknown or unmanaged. Port scans run daily in Intruder to track what is exposed. New service scans trigger in Intruder when something in the environment changes, and emerging threat scans run when a major new vulnerability is disclosed. The Intruder attack surface view shows every monitored port, the service running on it, and the version behind it, with a screenshot of each web service. Users of the Intruder attack surface view can search or filter by port, service, product, host status, or certificate expiry.[1][8]

Intruder cloud security needs no agents and connects to AWS, Azure, and Google Cloud accounts. Intruder connects to cloud accounts using read-only access, and nothing is deployed into the infrastructure. Intruder scans container images at the registry level. Intruder shows cloud misconfigurations, exposed secrets, insecure permissions, CVEs, and attack surface issues in one place.[8][9]

A ZAP-powered scanner in Intruder runs over 75 application checks for injection flaws, misconfigurations and zero-days. The same Intruder scanner integrates with CI/CD pipelines through GitHub, GitLab, Jira and Azure DevOps, and prioritizes results with remediation advice.

Intruder takes a white-box approach, working from source code. Intruder's agents are built and trained by CREST-certified pentesters and validate every finding against the application. Intruder delivers AI pentest results in a report containing an executive summary, full technical details, and remediation guidance. Intruder formats the AI pentest report to serve as compliance evidence for frameworks like SOC 2, ISO 27001, PCI DSS, and Cyber Essentials. Intruder also connects to a Bitbucket code repo to run a pentest on demand.[10][11]

Intruder integrates with Jira, GitHub, GitLab, Azure DevOps, and ServiceNow for issue tracking, Slack and Microsoft Teams for alerts, Drata and Vanta for compliance, and Microsoft Sentinel for SIEM. Intruder syncs container images from Docker Hub accounts for scanning. Intruder syncs targets from a Cloudflare environment and scans them for vulnerabilities. Intruder supports Okta SSO for authenticating users. Intruder prices the Cloud and Pro plans as a base fee plus a fee-per-target. Intruder quotes Enterprise pricing separately, because it depends on requirements and the size and complexity of the customer's systems. Customers can choose either a monthly rolling plan, which can be cancelled at any time, or an annual plan.[7][9][11]

Ravelin uses Intruder for continuous vulnerability scanning of its payment systems. Brainlabs relies on Intruder to find unknowns as new acquisitions reshape its attack surface. Hill & Smith uses Intruder to uncover hidden assets and expand visibility of its attack surface. Litmus uses Intruder to automate security and protect customer data. Surveil partnered with Intruder to gain attack surface visibility.[1][7][8][9][10]
