Booking Platform Penetration Testing

A hands-on security test of the application, and usually the API and staff back office behind it, that customers, providers and staff use to make, change and pay for bookings. We try to break your booking, availability, fee and role rules the way a real attacker or a dishonest user would, not just scan for known software vulnerabilities.

ISO 27001 does not require a penetration test. Annex A 8.8 applies once you declare that control applicable, and ISO 27002 guidance for 8.8 lists performing periodic, documented penetration tests. Yes, we can help either way: we test the booking app itself under our mobile application penetration testing service, including apps built with React Native or Flutter, and the API behind it, so the report supports your auditor’s review of Annex A 8.8. See our ISO 27001 penetration testing page for how we scope this.

A double booking happens when two requests for the same slot, room or resource both succeed because the system checked availability before it locked it. We send concurrent requests at the exact moment a slot is confirmed, across staff, resources and payment steps, to find the gap between the availability check and the booking write.

Yes. We test whether cancelling or rescheduling after your cut-off actually charges the fee your policy sets, whether a customer can cancel and rebook a related slot to dodge it, and whether deposit amounts, refund destinations and payment state survive a cancelled or disputed booking. See our payment platform and checkout and payment pages for the wider payment-integration scope.

Yes. We test whether a member of staff at one location or franchise can see, edit or cancel bookings at another, whether a provider can access another provider’s calendar or client list, and how the multi-location admin role is scoped.

Yes. Ticketing and event platforms share the same booking-logic risks with extra pressure at release time: inventory races when a high-demand event goes on sale, ticket transfer between accounts, resale and reissue abuse, and QR or barcode reuse at venue entry.

Yes. Hospitality and travel booking engines add their own logic: rate and availability manipulation across room types and dates, itinerary and booking privacy between guests, loyalty point balance integrity, refund handling, and the boundary between a franchise property and the parent brand’s booking platform.

Executive summary (board-ready), technical report with CVSS 3.1 scores, reproduction steps, screenshots, specific remediation guidance, and a 60-minute walkthrough call. Letter of attestation issued after free retest.

Yes. We sign client-supplied NDAs as standard. Engagement data is protected under our ISO 27001 (BSI-audited) information security management system.

From signed scope to active testing in 24 hours where required. Standard pipeline is 3-5 business days from initial scoping call to test start.

Every engagement is performed by vetted UK-based CREST-certified testers matched to your engagement based on security clearance, compliance scope, and sector specialism. Testers hold CREST certifications relevant to their discipline (CRT, CCT APP, CCT INF, CCSAM).
