Attackers don't wait a year. Why should your pen test?
Traditional external pen tests provide a snapshot. Intruder delivers continuous visibility. Our platform provides the deep insight of a vulnerability scan with the always-on monitoring that a once-a-year manual test can't match, giving you a proactive, real-time view of your security.

Stay secure with continuous external penetration testing
Intruder helps you protect the assets attackers target first - your websites, APIs, and internet-facing infrastructure. Our platform detects misconfigurations, weak encryption, open ports, and emerging vulnerabilities before they're exploited. Proactive Emerging Threat Scans and Rapid Response updates keep your external systems ahead of the latest exploits.
External penetration testing that scales with your infrastructure
Your attack surface isn't static. Intruder continuously maps new subdomains, login portals, and admin panels across your perimeter. Each change triggers an adaptive scan, giving you real-time visibility into what's exposed. With automated scanning, you'll always know your true risk - from the outside in.
Fix issues fast with workflow integrations
Enable teams with the information they need to remediate vulnerabilities quickly. Set up integrations and routing rules to send issues and remediation instructions directly into Jira, GitHub, GitLab, or ServiceNow.
