Your Guest's Browsers Are the Target
- 01
Client-side attacks go undetected
Your website loads dozens of 3rd party scripts (marketing tags, data integrations, analytics). One bad script exposes your guests to attacks.
- 02
Legacy tools miss dynamic attacks
Fraud tools and separate payment portals don't monitor the browser. CSPs and crawlers are evaded by attacks with dynamic JavaScript.
- 03
Compliance pressure is increasing
Hospitality & hotel platforms fall under PCI DSS, GDPR, and regional data laws that hold organisations accountable for 3rd party scripts.
- Monitor & secure every script to block malicious code from reaching guests
- Protect sensitive flows like booking and loyalty program pages
- Prevent violations of PCI DSS, GDPR, and HIPAA
- Reduce fraud with browser-layer forensics

Common Client-Side Attacks on Hospitality & Hotel Platforms
Magecart & E-Skimming
Code hidden on booking or payment pages steal card data and personal information
Expired Domains
Attackers purchase expired domains of scripts on your site to change code from an approved source.
Software Supply Chain
A breach in one of your trusted providers (analytics, chatbots, marketing tool) infects your entire site.
Dynamic JavaScript
Advanced threats target sessions with specific criteria (e.g. IP address) to evade traditional detection.
PII Leaks
Unmonitored scripts exfiltrate sensitive guest information such as passport data and stay details
Ad Injections
Injected ads or pop-ups inside the browser trick guests into clicking fraudulent booking links
Why Attackers Target Hospitality Platforms
High value data: Guest ID scans and card details are prime targets for attackers.
Multiple "trusted" scripts: marketing tags, chatbots, code libraries, and script tag managers are all entry points for browser attacks.
Easy to hide: Reservation and payment flows already collect sensitive data that attackers want.
Apps run client-side: Most bookings take place on a desktop or mobile browser, widening the attack surface beyond your servers.
