penetration testing as a service
The pen test that runs
every time you ship.
Muster's AI agents attack your live app, code, and cloud the way real attackers do, prove what's exploitable, and hand you the fix. Continuous, not once a year. From $49 a month, with the compliance report included.

the request that worked
GET /api/orgs/42/invoices Authorization: Bearer <user in org 7> → 200 OK reads another tenant's invoices
Broken tenant isolation (IDOR). Any user can read any org's billing data.
Scope the query to the caller's org in withOrg() before the invoice lookup.
one pen test, your whole surface
Everything an attacker can reach.
The agents don't just scan one layer. They connect your app, code, and cloud into a single attack surface and test it the way an intruder would.
Web & APIs
Auth, access control, business logic, injection, the flaws scanners miss.
Source code
Connect a repo. The agents read your code to aim the attack, not just list issues.
Cloud posture
Misconfigured buckets, roles, and exposure across your AWS, GCP, and Azure accounts.
Dependencies
Vulnerable packages traced to whether they're actually reachable and exploitable.
External surface
Subdomains, exposed services, and DNS the internet can already see.
no maybes
Every finding is a proven exploit.
A scanner hands you a list of things that might be wrong, and your team burns days triaging them. Muster only reports what it could actually exploit, and it shows its work: the exact request it sent, what that exposed, and the one change that closes it. Real holes, fixed. Not hypotheticals, triaged.
how it works
Live in three steps.
Connect
Point Muster at your app URL. It maps your APIs, repo, dependencies, and cloud into one surface.
Attack
AI agents run the attacker's loop against the live target and prove what's exploitable.
Fix & re-test
Each finding ships with the fix. Ship it, and Muster re-tests on every deploy.
vs a manual pen test
Continuous and proven, for less.
| Manual pen test | Muster. | |
|---|---|---|
| Cadence | Once or twice a year | Continuous, on every deploy |
| Deliverable | A PDF of findings you read once | A replayed exploit: the exact request, the impact, the fix |
| Coverage gap | Stale the next time you ship | Tests what you shipped today |
| Lead time | Weeks to scope and schedule | First results in ~10 minutes |
| Retests | Re-scope and re-quote each round | Unlimited, included |
| Compliance report | Often a $4k+ add-on | Included |
| Price | $15k–$30k per engagement | From $49/mo, listed on the page |
testing for compliance?
The SOC 2 / ISO 27001 report is included.
Most teams buy a pen test to satisfy an auditor or a customer security review. Muster produces the evidence they ask for as a natural output of the testing, at no extra charge.

Penetration testing, answered.
+What is penetration testing as a service (PTaaS)?
PTaaS replaces the once-a-year manual engagement with continuous, on-demand testing delivered through a platform. Muster runs AI agents that attack your live app, code, and cloud on every deploy, prove what is actually exploitable, and keep the evidence current, instead of a single point-in-time snapshot.
+How is this different from a vulnerability scanner?
A scanner lists things that might be vulnerable based on signatures. Muster's agents run the attacker's loop: they chain steps, abuse business logic and access control, and prove the exploit with the exact request that worked. You get confirmed, reproducible findings, not a queue of maybes.
+Can it replace my annual manual pen test?
For most teams shipping fast, a pen test that runs on every deploy and proves each exploit beats a $15k PDF that's stale the next week. For work that needs deep human judgment or a hand-signed attestation, humans stay in the loop, and the attested report is available when an auditor asks.
+Do I get a report for SOC 2 or ISO 27001?
Yes. Muster produces compliance-ready evidence as a natural output of the testing, and the report is included rather than a four-figure add-on. You can see a sample report before you buy.
+How fast can I see results?
Point Muster at your app, free, and the first proven findings land in about ten minutes. There's no scoping call and no scheduling.
+What does it cost?
Plans start 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. Pricing is on the page, no quote required.
