Penetration Testing for Hospitality & Hotels
Penetration testing shows a hotel how its booking engine, guest Wi-Fi, POS segmentation and front-desk staff hold up against the attacks the sector actually faces, in a controlled exercise scheduled around occupancy. Operators usually commission a test when an acquirer or insurer asks for evidence, after a cloud PMS migration, or after a phishing near miss rattles the desk. You get findings ranked by real-world consequence, not a scanner dump.

What you're protecting
What a hotel pen test has to reach
A meaningful test covers the property the way an attacker sees it: one building holding card data, guest whereabouts and a staff of busy, trusting people.
The booking engine and payment pages
Direct bookings flow through web applications connected to the CRS and payment gateway, and the March 2025 tightening of SAQ A pushed script integrity and page tampering onto every operator's agenda. Testing probes exactly the weaknesses those changes target.
Guest Wi-Fi and network segmentation
Hundreds of unknown devices join your network nightly through Meraki or Ruckus hospitality gateways. The question that matters is whether a laptop in room 412 can see the POS VLAN, the PMS server or the CCTV network, and only a test answers it with evidence.
Front-desk workstations and the humans at them
Agents juggle the PMS, OTA extranets and a public email inbox on the same machine. Simulated phishing shaped like the lures hotels really receive measures whether that combination holds under pressure.
Door locks, encoders and master keys
Key-card platforms such as Saflok, VingCard and Salto, the encoders behind the desk and the master key hierarchy are security systems in their own right, and their configuration and update status belong in scope.
Remote access and vendor paths
The MSP, the PMS vendor and interface integrators all hold ways into the property network. A test enumerates those doors and checks which are protected by more than a password.
Regulatory map
The requirements that put hotels on a testing schedule
Testing is rarely done for curiosity. For hotels it is pulled by payment rules, privacy law and the safeguard benchmarks regulators have already set for this sector.
PCI DSS segmentation and testing expectations
With card-present lanes, MOTO and e-commerce in one environment, PCI DSS v4.0.1 expects operators to validate that segmentation actually isolates cardholder data, and acquirers increasingly ask for testing evidence with the attestation.
PIPEDA-appropriate safeguards, demonstrated
Safeguarding guest data proportionate to its sensitivity is a legal duty, and independent testing is one of the clearest ways to demonstrate you checked rather than assumed.
Quebec's expectations for new systems
Law 25 pushes Quebec properties to assess projects involving personal information, and a post-migration test of the new PMS or booking platform gives that assessment technical teeth.
What goes wrong
Attack paths we emulate on a live property
The scenarios come from documented incidents against hotels, replayed safely against your environment.
ClickFix lures aimed at the desk
Storm-1865's Booking.com-themed campaign walks staff through fake verification pages that execute credential stealers. Our simulations reproduce that pattern, without malware, to measure who clicks, who runs the steps and who reports it.
The pivot from guest network to card systems
An attacker who joins guest Wi-Fi and finds a route toward POS terminals or the PMS interface network gets everything a remote phish gets, from a parking spot outside. Segmentation testing proves whether that route exists at your property.
Abuse of the booking and loyalty surface
Public-facing reservation and loyalty pages invite credential stuffing, payment-page manipulation and logic abuse around cancellations and rate codes. Application testing exercises those behaviours before someone hostile does.
Forged credentials at the room door
The Unsaflok disclosure showed how lock-system weaknesses can turn a spare keycard into a master key. We review your lock platform's exposure and management practices as part of the property's overall attack surface.
Our pen testing for hospitality & hotels
What our testing covers for hotel properties
Scope is assembled per property and per portfolio, so you buy the assessments that answer your acquirer, insurer and your own doubts.

External and application testing
The booking engine, website, loyalty portal and any exposed remote-access services are probed from the internet, with attention to payment flows and the pages your acquirer cares about.
Internal and segmentation testing
On-site work verifies the boundaries between guest Wi-Fi, corporate, POS and building-systems networks, and looks for the flat-network shortcuts that accumulate in older properties.
Social-engineering exercises
OTA-themed phishing simulations and pretext calls against front desk and reservations, coordinated with management, sized to inform training rather than embarrass individuals.
Key-card and physical-system review
An assessment of the lock platform, encoder custody, master-key discipline and vendor patch status, flagging where your property stands relative to known weaknesses in deployed lock lines.
Findings and improvement guidance
A report that separates urgent exposures from housekeeping, maps results to PCI and insurer expectations, and gives your MSP directional guidance it can act on in the next maintenance window.
How the engagement runs
Testing around occupancy, not against it
Hotels never close, so the exercise is engineered to leave guests and revenue untouched.
Step 1
Scope and schedule with operations
We agree rules of engagement with the GM and MSP, choose shoulder-season windows and overnight low-occupancy periods, and explicitly fence off systems where interruption is unacceptable.
Step 2
Test in controlled stages
External work runs first from outside the property, on-site network and segmentation checks follow during quiet periods, and phishing simulations run over normal working weeks to get honest results.
Step 3
Debrief the people who own the fixes
Findings are walked through with the GM, controller and MSP in plain language, ranked by what an attacker could actually do with each weakness at your property.
Step 4
Support remediation and evidence
We help translate the report into acquirer and insurer responses and into a short remediation plan, and remain available as fixes land to confirm the intent was met.
What it costs
What shapes the price of a hotel pen test
Cost follows scope and constraints: the number of properties and locations, whether the engagement covers external, internal, application, social-engineering and lock-system components or a subset, the size of the network estate, and the scheduling limits occupancy imposes on on-site work. Night-window testing and multi-property sampling both shape effort.
A focused booking-engine test for one independent property is priced very differently from a portfolio exercise across ten flags with phishing simulations. Describe your stack and what your acquirer or insurer is demanding, and we will return a scoped quote.
Hospitality & Hotels: Pen testing questions, answered
Yes. Application testing runs against agreed targets with throttled, non-destructive techniques, and anything transactional can be exercised in a staging environment or during defined low-traffic windows with rollback contacts on call. Guest Wi-Fi assessment is passive to guests; we test the boundaries around the network rather than interfering with people using it. In hospitality engagements we treat reservation continuity as a hard constraint, written into the rules of engagement.
That is one of the most valuable exercises a hotel can run, precisely because real campaigns use those lures. We build simulations that mirror the current pattern, fake guest complaints, verification requests and CAPTCHA-style pages, deliver them to desk and reservations teams over normal weeks, and measure clicks, credential entry and reporting. Results arrive anonymized by team, paired with recommendations, so the outcome is better training rather than blame.
On paper, usually; in practice, often not. Properties accumulate exceptions: a printer bridged across VLANs, an old interface server reachable from everywhere, a vendor router with a flat view of the building. Segmentation testing attempts the crossings an attacker would attempt, from guest network toward POS, PMS and CCTV, and documents exactly which ones succeed. That evidence either validates your PCI scoping or tells you precisely what to fix before the attestation.
We include lock platforms in scope as an assessment: identifying the model and firmware generation deployed, whether known weaknesses affect it, how encoders and master-key levels are controlled, and what the vendor's remediation path looks like. We do not attempt to force guest-room doors during a live stay. The output is a clear position on your exposure and the questions to put to your lock vendor, which most operators have never had in writing.
Annual testing is the workable baseline for most properties, aligned with insurance renewal or PCI attestation cycles so the evidence is fresh when it is needed. Material change resets the clock: a cloud PMS migration, a new booking engine, a payment-provider switch or a network redesign all alter the attack surface enough that last year's report no longer describes your property. Retesting after such changes is when we find the most serious issues.
