Hospitality

Guest Data Stays on Your
Property's Machines.

Front desk agents, event coordinators, and revenue managers are using ChatGPT, Claude, and Copilot every day, pasting guest reservations, credit card numbers, loyalty profiles, and event contracts into prompts. Shield sits on your hotel's workstations and stops guest data from ever reaching an external AI model. No cloud. No vendor access. Just a local proxy that redacts sensitive data before it leaves your property network.

Quick Answer

Shield for Hospitality is a local desktop application that stops guest PII, credit card data, loyalty program records, and event contracts from ever leaving your hotel's computers, before that data reaches ChatGPT, Claude, Copilot, or any AI model. It runs on your existing property workstations, requires no cloud infrastructure, and helps hotels meet PCI DSS, GDPR, and CCPA requirements without changing how staff use AI tools for guest communications, loyalty analysis, or event planning.

PCI DSS
Payment card security standard

The Payment Card Industry Data Security Standard (PCI DSS) applies to any organization that stores, processes, or transmits cardholder data. When a front desk agent pastes a guest's credit card number into an AI prompt, that data leaves the hotel's cardholder data environment, potentially violating PCI DSS Requirement 3 (protect stored cardholder data) and Requirement 4 (encrypt transmission across open networks).

Multi-Jurisdiction
GDPR, CCPA, and state data breach laws apply

Hotels routinely process data from guests across dozens of countries and U.S. states, each with its own privacy and breach notification requirements. GDPR applies to any EU resident's data regardless of where the hotel is located. California's CCPA/CPRA gives guests the right to know what personal data is collected and shared. All 50 U.S. states have data breach notification laws. When guest data enters an AI provider's systems through employee prompts, it may trigger notification obligations the hotel never planned for.

Guest data leaves your property network

Shield runs locally on your hotel staff's machines, no cloud processing, no vendor data access. Guest PII, credit card numbers, loyalty profiles, and event contracts never reach external AI providers. The redaction mapping stays on your machine, inside your property's network boundary.

Shield operates within your network boundary

Guest data exposure through AI is a PCI DSS and GDPR compliance risk

When a front desk agent pastes a guest's reservation, credit card number, or passport details into an AI prompt, that data leaves your property's controlled cardholder data environment and arrives at an external provider's servers. Under PCI DSS, hotels must protect cardholder data wherever it is stored, processed, or transmitted. Under GDPR, international guest data requires cross-border transfer safeguards. Shield eliminates this vector entirely: sensitive guest information never leaves your network, so it never creates a PCI DSS, GDPR, or CCPA compliance exposure.

Front Desk Agent Using AI to Draft Guest Welcome Letters

A front desk agent at a resort uses an AI assistant to draft personalized welcome letters for VIP guests arriving that day, pasting reservation details, credit card information, and passport data into the prompt.

How Shield Protects Guest Data at Your Property

From front desk to AI provider, every piece of guest data that would leave your property network is caught, redacted, and only the clean prompt makes it to the internet.

Compliance Frameworks That Apply to Hospitality AI Use

Hotels operate under multiple overlapping data protection frameworks, from payment card security to international privacy laws. Here is how Shield maps to the requirements that matter when your staff use AI tools with guest data.

PCI DSS v4.0
Scope: Cardholder data, PAN, cardholder name, expiration, CVV
Requirement

Protect stored cardholder data (Req 3); encrypt transmission across open, public networks (Req 4); restrict access to cardholder data by business need-to-know (Req 7)

How Shield Helps

Redacts PANs, cardholder names, and payment data before prompts leave the hotel's cardholder data environment. The AI provider never sees payment card information, satisfying the transmission encryption and data protection requirements for this vector.

GDPR
Scope: Personal data of EU residents, name, passport, contact, payment, preferences
Requirement

Lawful basis for processing; data minimization; purpose limitation; cross-border transfer safeguards; 72-hour breach notification

How Shield Helps

Prevents cross-border data transfers of EU guest PII by redacting personal data before it leaves the local machine. Since the data never reaches external AI servers, there is no GDPR-regulated transfer, no processing by a third party, and no breach notification trigger.

CCPA / CPRA
Scope: California residents, personal information collected by businesses
Requirement

Right to know what personal information is collected and shared; right to delete; right to opt-out of sale/sharing; data minimization and purpose limitation under CPRA

How Shield Helps

Prevents unauthorized sharing of California guest data with AI providers. Because Shield redacts PII before it leaves the hotel's systems, the data is never 'shared' or 'sold' to a third party under CCPA definitions, satisfying the opt-out and data minimization requirements for the AI use case.

State Breach Notification Laws
Scope: All 50 U.S. states, personal information breach notification triggers
Requirement

Notify affected residents (and often state AGs) within specified timeframes when unencrypted personal information is acquired by an unauthorized party; triggers vary by state for what constitutes PII and what qualifies as a breach

How Shield Helps

Shield prevents the data exposure from occurring in the first place, guest PII is redacted before it can reach an AI provider's systems. No data leaves the hotel's control, so there is no unauthorized acquisition, no breach, and no notification obligation for this vector.

Frequently Asked Questions

PCI DSS Requirement 3.4 requires that cardholder data be rendered unreadable anywhere it is stored, but when front desk staff paste credit card numbers into AI prompts, that data leaves your property's controlled environment and arrives in plain text at an external provider. Shield redacts Primary Account Numbers (PANs), cardholder names, CVV codes, and expiration dates before they leave your network. Because Shield runs locally, the redaction happens inside your POS/PMS network boundary, the external AI provider never sees cardholder data. This doesn't replace your PCI DSS compliance program, but it closes a vector that traditional tokenization and encryption don't cover.
Yes. When a European guest checks into your property, their passport data, contact information, payment details, and stay preferences are protected under GDPR regardless of where your hotel is located. If your staff use AI tools, ChatGPT, Claude, Copilot, or any cloud-based assistant, and paste guest data into prompts, that data transfers to servers that may be outside the EU/EEA. Shield prevents that cross-border transfer by redacting personal data before it leaves your machine. The redaction mappings stay local, meaning the data transfer never happens, which is the strongest possible GDPR safeguard.
Shield operates at the network layer. It sits between your AI client application and the LLM provider's API. It doesn't need to integrate with your Property Management System (PMS), Central Reservation System (CRS), or Point of Sale (POS). As long as staff are using AI tools on their workstations, whether they copy-pasted data from Opera, sent it through SynXis, or typed it manually. Shield catches and redacts the sensitive fields before they reach the external AI. No PMS integration, no API calls to your hotel stack. Shield runs independently on each staff member's machine.
Loyalty program data is among the most sensitive in hospitality. A member profile typically contains full name, address, phone, email, date of birth, credit card token, airline frequent flyer numbers, stay history (dates, properties, room numbers), spending totals, room preferences, dietary restrictions, and milestone recognition dates. This is a goldmine for identity theft and competitive intelligence. Shield's filter packs detect member IDs, frequent flyer numbers, birth dates, addresses, financial figures, and preference data, all of which would be exposed if a loyalty manager pastes an Excel export into an AI tool for analysis. The data is redacted before it leaves the hotel's network.
Absolutely. A corporate group booking or wedding block involves contracts with client company details, tax IDs, credit card authorizations, banquet event orders with attendee names and dietary/medical information, and often VIP security details. These documents contain PII, PCI data, trade secrets (corporate event calendars reveal product launch timing), and protected health information (severe food allergies with EpiPen carrier names). Shield redacts all of these categories before an event coordinator can inadvertently expose them by using AI to draft, summarize, or analyze event documents.
Shield installs on any Mac, Windows, or Linux machine, front desk workstations, sales manager laptops, event coordinator desktops, and revenue management systems. For a multi-property chain, your IT team can push Shield via MDM or group policy with property-specific configuration (e.g., different data residency rules for EU properties vs. US properties). All redaction happens locally on each machine, no central server, no cloud dependency, no data aggregation risk. Audit logs can be centrally collected if your security team needs visibility into what's being redacted across properties.
