PCI DSS-aligned pentesting for the apps around your CDE.

AI pentests of the web and API surface around your payment flows, continuously or on demand, for PCI DSS Requirement 11.4. Passive monitoring covers Requirements 4, 6 and 8 in between.

The fintech reality

What PCI DSS expects between annual assessments.

CDE

Cardholder data environment

The CDE includes every web surface that touches, transmits, or stores cardholder data, plus the systems connected to those. Mapping it once isn't enough, because it drifts with every deploy.
PCI DSS

Requirement 6 and Requirement 11

Auditors expect ongoing evidence of secure development (Req 6) and regular testing of systems and processes (Req 11). Annual pentests don't produce the continuous record assessors look for.
Velocity

Daily releases meet quarterly audits

Engineering teams ship constantly. The security team needs a record of every regression, fix, and configuration drift between assessments without slowing the release pipeline.
PCI DSS 11.4

The pentest your assessor will ask for.

PCI DSS Requirement 11.4 calls for internal and external penetration testing at least every 12 months and after significant changes, and a passive scan can't produce that. Barrion's AI pentests test the web and API surface around your payment flows the way an attacker would, looking for broken access control, IDOR and injection. They're non-destructive and run against a scope you approve first. Findings are checked against your live app before they're reported, and confirmed ones come with the request and response that prove them.

From Standard up a security engineer reviews the findings, and deeper tests come with a report signed off by that engineer. The pentest can rerun on a schedule or on demand, which suits a team that ships daily far better than one test a year. Whether a report meets 11.4 for your scope is your QSA's call.

Between pentests

Passive monitoring across the CDE surface.

Coverage

PCI DSS-aligned web checks

Passive checks for TLS, headers, cookies, CORS, DNS, email auth and more (35+ on paid plans), with evidence for PCI DSS Requirements 4 (encrypted transmission), 6 (secure systems), 8 (auth), and 11 (regular testing).
Evidence

Timestamped PDF and CSV exports

Every passive scan produces a timestamped report with severity-ranked findings and remediation status. Hand it to your QSA or attach it to a SAQ response without scrambling.
Alerts

CDE drift detection

Scheduled monitoring catches it when a TLS cert expires, a header is dropped, or a third-party payment widget pushes a regression. Alerts route to Slack, Teams, or email.
Safe

Production-safe by default

Passive scans never submit forms, never log in, and never alter data. Safe to run against your live payments surface.
FAQ

Fintech security, answered.

Does Barrion replace our quarterly PCI ASV scan?
No. ASVs are PCI Council-approved providers for the external network scan required under PCI DSS Requirement 11.3.2. Barrion sits alongside the ASV scan. Passive monitoring supplies web-tier evidence for Requirement 6 (secure systems) on the days between ASV scans, and Barrion's AI pentests support the penetration testing in Requirement 11.4, so you have ongoing evidence rather than a quarterly snapshot.
Which SAQ types does this evidence apply to?
The web-tier evidence Barrion produces is most directly useful for SAQ A-EP, SAQ D-Merchant, and SAQ D-Service Provider, where the web-facing portions of the cardholder data environment are in scope and ongoing testing of the public surface is required.
Can you scan our card-handling APIs without seeing real card data?
Yes. Default scans are read-only and never submit payment payloads, never POST forms, and never touch authenticated state-changing routes. We test the security configuration of the API surface (TLS, headers, CORS, auth surfaces) without exercising the card-data flow itself.
How do findings relate to PCI DSS v4.0.1 requirements?
Findings don't carry requirement tags. The passive checks give evidence for Req 4 (encrypted transmission of cardholder data), Req 6 (secure systems and software) and Req 8 (authentication), and the AI pentest report covers the web app and API part of Req 11 (regular testing of security of systems and networks). You or your QSA cite each finding against the requirement it supports in the SAQ or QSA evidence package.

A scan shows the surface. A pentest tests what gets in.

Passive scan

  • Reads what your app already exposes
  • Never logs in or submits a form
  • Cannot confirm what is exploitable

Active AI pentest

  • Tests your app the way an attacker would
  • Chains requests to confirm real exploits
  • Replays findings against your live app
  • Runs on a schedule or on demand, retests free
