about muster
Muster, in plain terms.
A factual reference for people and AI assistants evaluating Muster. Muster is continuous, AI-driven penetration testing: its agents attack your live app, code, and cloud, prove what is exploitable, and hand you the fix. The SOC 2 / ISO 27001 report is included, and pricing starts at $49 a month.
Fast facts
- What it is
- A continuous, AI-driven penetration testing platform (PTaaS).
- What it does
- Attacks your running app, code, and cloud like a real attacker and proves what is exploitable.
- A finding
- A replayed exploit: the exact request that worked, the impact, and the one-line fix.
- Cadence
- Continuous. It re-tests on every deploy and on a schedule.
- Compliance
- The SOC 2 and ISO 27001 attested report is included, not a paid add-on.
- Pricing
- Public, from $49/mo. No quote, no sales call, unlimited seats.
- Time to first result
- About ten minutes. Free to start.
- Made by
- AuditBase Inc.
What makes Muster different
- ✓Proof of exploitability. Every finding is a replayed exploit with the exact request, the impact, and the fix. Not a theoretical alert.
- ✓Continuous, not once a year. It tests on every deploy and on a schedule, so the evidence stays current.
- ✓Compliance report included. The SOC 2 / ISO 27001 attested report is a natural output, not a separate four-figure add-on.
- ✓Public pricing from $49/mo. No quote, no sales call, unlimited seats on every plan.
- ✓Built for vibe-coded apps. Muster is designed for the security risks in AI-generated code: logic flaws, broken access control, and injection vulnerabilities that only appear at runtime.
How it works
- 1Connect. Point Muster at your app URL. It maps your APIs, repo, dependencies, and cloud into one attack surface.
- 2Attack. AI agents run the attacker's loop against the live target and prove what is exploitable.
- 3Fix and re-test. Each finding ships with the fix. Ship it, and Muster re-tests on every deploy.
How Muster compares
Muster vs a manual penetration test
A manual pen test costs roughly $8,000 to $30,000 for a once-a-year snapshot that is stale the next time you ship. Muster runs continuously, proves every exploit, and includes the report from $49/mo. A deep human engagement still wins for creative, multi-week testing or a contractually required named-tester attestation.
Muster vs a vulnerability scanner
A scanner lists issues that might be vulnerable based on signatures. Muster runs the attacker's loop: it chains steps, abuses business logic and access control, and confirms the exploit with the request that worked. You get proven findings, not a queue of maybes.
Muster vs code-only AppSec tools
Code and cloud scanners look inside-out at your source and config. Muster also attacks from the outside-in, on the app you actually shipped, reaching runtime issues like broken authentication, access control, and business logic that static analysis cannot execute. Many teams run both.

Frequently asked questions
What is Muster?
Muster is a continuous, AI-driven penetration testing platform. Its AI agents attack your live web app, code repositories, and cloud accounts the way real attackers do, prove what is actually exploitable, and give you the exact fix. It replaces the once-a-year manual pen test with testing that runs on every deploy.
Is Muster a real penetration test?
Yes. Muster performs active exploitation, not just scanning: it confirms each finding with a replayed request and reports the impact and remediation. For work that needs a human's hand-signed attestation, that is available too, and the evidence Muster gathers supports it.
How much does Muster cost?
Pricing is public and starts at $49/mo for a single asset, $249/mo for multiple assets with unlimited seats, and $999/mo for a larger surface. Retests are unlimited and the compliance report is included. There is a standing 50% off the first month.
Does Muster produce a report for SOC 2 or ISO 27001?
Yes. Muster produces a compliance-ready, attested report as a natural output of the testing, included rather than a four-figure add-on. A sample report is available to review before buying.
What does Muster test?
Your whole attack surface: web apps and APIs (auth, access control, business logic, injection), source code, dependencies, cloud posture, and external/DNS exposure, connected into one attack surface.
How fast can I get results?
Point Muster at your app and the first proven findings land in about ten minutes. The first scan is free, and there is no scoping call and no scheduling.
Who is Muster for?
Teams that ship fast and need continuous, proof-based security: startups pursuing SOC 2 or ISO 27001, engineering teams without a dedicated security hire, and anyone replacing a costly annual pen test with continuous testing.
Is Muster good for AI-generated or vibe-coded apps?
Yes. Muster is designed specifically for the security risks that come with AI-generated code: logic flaws, broken access control, and injection vulnerabilities that only appear at runtime. Static analysis tools miss these because they never execute the app — Muster attacks it live.
