How does an on-demand pentest work?
An on-demand pentest is a penetration test you start yourself, immediately, with no scoping call or vendor scheduling. You point the system at your app, AI agents map your attack surface and begin attacking it like a real intruder, and every finding is proven with the exact request that worked. Muster is an instant pentest in practice: first proven exploits land in about ten minutes, the same attack replays on every deploy, and the SOC 2 / ISO 27001 evidence is included. From $49 a month, with a free first test.
what the old model costs
Why does a manual pentest take weeks?
The scoping call
Every manual pentest starts with weeks of scheduling, scoping, and quoting before anyone touches your app.
The retest fee
Fix a finding and pay again to verify the fix. Traditional engagements charge per round.
The stale report
A point-in-time snapshot that stops reflecting reality the moment you ship the next deploy.
The surprise bill
A compliance report sold as a four-figure add-on after the engagement ends.

Built for teams that ship.
- ✓You ship weekly and a point-in-time snapshot is stale before you finish reading it
- ✓You need findings today for a launch, a customer review, or an investor ask
- ✓You want the exploit proven with the exact request, not triaged from a scanner list
- ✓You do not have a scoping-call budget or a security hire to manage a vendor

On-demand pentest, answered.
+What is an on-demand pentest?
An on-demand pentest is a penetration test you start yourself, immediately, without scheduling an engagement. Muster's AI agents attack your live app on demand, prove what is exploitable with the exact request, and hand you the fix. No scoping call, no waiting, no sales conversation before you see a result.
+Is it a real pentest or just a scan?
A real pentest. The agents run the attacker's loop: recon, attack, prove, retest. A finding only exists if it was successfully exploited with a real request. Scanners list maybes; we prove exploits.
+How fast can I actually start?
Point Muster at your app URL and the agents start attacking. First proven findings land in about ten minutes. Free to start, no demo call.
+Does an on-demand pentest work for SOC 2 or ISO 27001?
Yes. Every proven finding comes with compliance-ready evidence: the exact request, the response, the impact, and the remediation. The SOC 2 and ISO 27001 attested report is included at no extra charge, and a sample report is on the site before you buy. When an auditor or customer security review asks for your pentest evidence, this is what they get: proven exploits with fixes, not a scanner export.
+What if I need a human pentester too?
For deep creative work or a hand-signed attestation requirement, human engagements still have a place. Muster covers the continuous, exploit-proving layer; a human can still do the annual deep-dive. Many teams run both.
