Know which findings are worth your time

Cut the false positive triage. Intruder’s AI agents confirm whether a finding can be exploited, so you only send developers the real problems.

Catch weaknesses before they ship

Intruder’s API lets you scan your test environment from your CI/CD pipeline, so issues can get fixed during development instead of patched in a hurry after release.

Always audit-ready

Generate reports for auditors and customers, or send evidence straight to Drata or Vanta. Audit prep stops eating your week.

Scan your APIs in CI/CD and fix what’s exploitable first

Get started in minutes

Upload your OpenAPI or Swagger schema and add authentication to scan endpoints behind logins.

Scheduled scans, server included

Run API scans on a recurring schedule or on-demand. Intruder also checks the server hosting your API for outdated software, missing patches, and encryption weaknesses.

Prioritize and fix

Results are prioritized by CVSS and exploit likelihood. Send them to Jira, GitHub, or Azure DevOps, and rescan individual issues to confirm your fixes worked.

Our customers love Intruder

Emerging Threat Scans are a game changer. They let us  stay on top of everything, without hours spent checking  sources or reconfiguring platforms. Having full visibility  into what's externally exposed has massively increased our confidence.

Pawel Sieradzki
Global IT Director, Brainlabs

If you leave room for doubt in the sales process, you  can derail the entire deal. I wanted security to be  something we look forward to prospects asking about. Now  the security review is one of the fastest parts of the  deal stage.

Zach Rattner
CTO & Co-founder, Yembo

I want to take us out of the equation completely from  a process perspective. We're not the nagging manager  anymore, we just monitor and make sure things are  progressing. When my CIO asks where we stand, I can tell  him straight away: no highs, no criticals.

Sunil Patel
ISO, River Island

One platform. Continuous security.

Does Intruder help with SOC 2 and ISO 27001 compliance?

Yes — generate audit-ready reports for frameworks like SOC 2, ISO 27001, and HIPAA to share with auditors or upload into compliance tools like Drata and Vanta.

Will it work with our existing stack?

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. See all our integrations.

What does Intruder check for when scanning APIs?

Intruder runs 100 application-level checks against every endpoint defined in your schema, covering SQL injection, NoSQL injection, XSS, OS command injection, LDAP injection, server-side code injection, and more. Every scan also checks the server hosting your API for outdated software, missing patches, and encryption weaknesses. See the full list of checks.

Do I need an API schema to scan?

Intruder supports OpenAPI and Swagger schemas. Upload your schema and Intruder scans every endpoint defined in it. Without a schema, Intruder still runs infrastructure-level checks against the server hosting your API. See how to upload your schema.

Can I run API scans from my CI/CD pipeline?

Yes. Intruder's API lets you trigger scans from your CI/CD pipeline, so you can catch vulnerabilities during development rather than after release. See the API documentation.

How does Intruder reduce false positives in API scanning?

Intruder's AI agents validate whether a finding can be genuinely exploited before it's reported, so developers only see the real problems. Learn more about AI issue validation.
