Results in hours, not weeks

Get actionable findings immediately - no waiting for an engagement to start or a report to land.

Stay ahead of emerging threats

When new vulnerabilities are announced, Intruder checks your systems automatically - so you know your exposure before exploits spread.

Always-on coverage

Continuous checks between manual pentests, so new risks don't sit undiscovered for months.

AI pentesting and issue verification on demand

Intruder's AI pentesting tests the web apps running in your cloud, investigating findings the way an experienced tester would to confirm what's actually exploitable in your environment. You act on real, reachable risk, not a backlog of maybes.

Know if you'd pass an audit before the auditor asks

Intruder checks for the issues auditors care about - exposed services, missing encryption, unpatched software - and generates compliance-ready reports for SOC 2, ISO 27001, or HIPAA without manual evidence gathering.

From finding to fixing, without the back and forth

Intruder integrates with Jira, GitHub, GitLab, and Slack to route findings to the right team automatically. GregAI triages issues, explains root causes, and drafts remediation notes, so fixes happen faster without chasing people for updates.

What is AI pentesting?

AI pentesting uses autonomous AI agents to run a web app penetration test the way a skilled human pentester would. The agents reason through how your application behaves, find vulnerabilities, test attack paths, and validate that each one is genuinely exploitable, all without a human running the test. Because Intruder takes a white-box approach, the agents work from your source code, so they can reach issues a scanner structurally can't. You get an audit-ready report with an executive summary, full technical detail, remediation guidance, and a transcript of every step the agents took.

Does Intruder cover cloud and container security?

Yes. Intruder runs daily cloud configuration checks across AWS, Azure, and Google Cloud to flag misconfigurations, insecure permissions, and exposed secrets. It also discovers and scans container images in your cloud registries, enabling you to catch vulnerable containers before they’re deployed in production.

What integrations does Intruder support?

Intruder integrates with Jira, GitHub, GitLab, Azure DevOps, and ServiceNow for issue tracking, Slack and Microsoft Teams for notifications, Drata and Vanta for compliance, Zapier for workflow automation, and Okta for SSO, plus native cloud sync with AWS, Azure, and Google Cloud.
