OBRYN GUARD® • HOTEL SYSTEMS BRIEF
Hotel Systems
Hotels don’t get breached because systems are “mysterious.” They get breached because access is messy: shared accounts, weak vendor controls, missing MFA, and staff doing urgent work on the wrong device. This page shows the systems that matter, where risk enters, and how OBRYN Guard locks down access and produces proof for insurance and audits.

Which systems matter most (risk + underwriting)
Underwriting questions are basically: “Which systems hold sensitive data or money?” and “Can the wrong person access them?” These are the systems that usually decide insurability.
PMS / reservations
- Guest profiles + booking history
- Refunds, cancellations, folios
- Role access usually misconfigured
- Vendor integrations expand exposure
POS / payments
- Terminals used across shifts
- Refund abuse and fraud exposure
- Back-office logins often shared
- Downtime directly hits revenue
Email (business control)
- Approvals + invoice routing
- Vendor impersonation risk
- Password-only access = common fail
- Often the first entry point
Where risk enters (the actual failure points)
Most incidents follow predictable lanes. Fix the lane, not just the symptom.
Lane 1 — Access sprawl
Too many people have too much access for too long.
- Shared admin accounts for speed
- No quarterly access reviews
- Leavers keep access
- Generic “manager” roles everywhere
Lane 2 — Password-only logins
A stolen password becomes direct entry.
- MFA “optional” or disabled for vendors
- Password reuse across systems
- Weak PINs and shared notes
- Login from unknown devices
Lane 3 — Email-driven approvals
Attackers exploit “fast approvals” and “urgent requests.”
- Vendor invoice changes
- Refund approvals and chargebacks
- Export requests (“send the guest list”)
- Support ticket impersonation
Lane 4 — Device + network gaps
Unpatched devices and flat networks turn small issues into big incidents.
- Outdated front desk PCs
- Guest Wi-Fi not segmented
- Remote access unmanaged
- Endpoint protection inconsistent
