the deliverable

A report you can hand straight to your auditor.

Auditors do not want a scanner export. They want scope, methodology, proven findings, remediation, and a signature. That is exactly what the attested report is.

  • Scope & methodology

    What was tested, when, and how, aligned to OWASP-style categories your auditor will recognize.

  • Findings with severity

    Each finding rated, described in plain English, with the exact request that proved it.

  • Remediation & retest

    The fix for every finding, and retest evidence once you ship it. Closed means proven closed.

  • Signed attestation

    A signed, dated attestation of the engagement, in a form procurement and auditors accept.

what it costs

A fraction of a traditional engagement, and the price is public.

Running the pen test is free. Paid plans start at $199/mo billed annually, and every annual plan includes a signed, attested report each year. Traditional firms start around $20,000 per engagement.

Compliance questions.

+Does SOC 2 actually require a penetration test?

SOC 2 does not name a specific tool or test, but auditors ask for evidence that you test your security controls, and enterprise customers ask for a pen test report by name. An attested report from a real test is the standard artifact that satisfies both.

+Will my auditor accept an AI-driven pen test?

The report documents scope, methodology, findings, and proof in the same structure a traditional firm delivers, and every finding is a real, replayed exploit rather than a scanner guess. Humans stay in the loop for the signed attestation. Auditors vary in what they require, so the best first step is to send yours the sample report and confirm it fits their expectations.

+How fast can I have the report?

The test starts in minutes and most teams have findings the same day. The attested report is typically ready within days, not the weeks it takes to schedule a traditional firm.

+What does it cost?

Running the pen test is free on one app. Paid plans start at $199/mo billed annually, and every annual plan includes a signed, attested report each year. You can also buy a report as a one-off. It is a fraction of the $20k+ a traditional engagement costs, and all pricing is public with no sales call.

+Is it safe to run before an audit?

Yes. Muster is non-destructive by default: scoped to targets you authorize, rate-limited, and read-only where it can be, with no data-changing payloads. You can point it at staging first if you prefer. Every finding includes the exact request the agent sent, so nothing is hidden.

+We failed a security review. Can this help fast?

Yes. Run the free pen test now, fix the proven findings with the provided remediations, retest, and export the report showing everything closed. Teams use exactly this loop to unblock stalled deals.

+Does it cover ISO 27001 too?

Yes. The same attested report serves ISO 27001 audits, vendor security reviews, and customer questionnaires. One test, one artifact, reused everywhere.

Your auditor is waiting. Your pen test doesn't have to.
