How cside Protects Hospitality Platforms 
Client-Side Intelligence
Our hybrid proxy architecture provides comprehensive client-side protection specifically designed for the unique challenges of hospitality platforms.
Your Guest's Browsers Are the Target
Your website loads dozens of 3rd party scripts (marketing tags, ad scripts, booking engines). One bad script exposes your users to attacks.
Isolated payment portals don't monitor the rest of the browser (e.g. forms). CSPs and crawlers are evaded by attacks with dynamic JavaScript.
PCI DSS, GDPR, and other compliance frameworks are holding organizations accountable for 3rd party script data leaks.
Our hybrid proxy architecture provides comprehensive client-side protection specifically designed for the unique challenges of hospitality platforms.
Our proxy monitors the activity of every script, blocking malicious code from reaching users on your platform.
PCI 6.4.3 & 11.6.1 requirements with script inventory, change detection, justifications, and audit-ready reports.
Identify what personal data each third-party script has access to and where it's sent. Stay compliant with GDPR + HIPAA by preventing PII leaks.
Our system creates device fingerprints for every user session, enabling detection of suspicious activity from bots or humans at the browser level.
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.
"Our experts can conduct a client-side vulnerability assessment and provide a customized recommendation."

Common Client-Side Attacks on Hospitality Platforms
Code hidden on reservation flows or payment pages steal card data and personal health information
Attackers purchase expired domains of scripts on your site to change code from an approved source.
A breach in one of your trusted providers (analytics, chatbots, tag managers) infects your entire site.
Advanced threats target sessions with specific criteria (e.g. IP address) to evade traditional detection.
Misconfigured or malicious scripts bypass your privacy policy to exfiltrate sensitive PII.
Fake login or consent fields displayed over UI elements to harvest login credentials.
Don't Wait for a Data Breach or Audit Failure
cside tells me everything I need to know about a script, and makes sure they are safe to show to the user. It's really made me realize how big of a problem 3rd party script security is, and there are no other solutions I've tried that dive as deep as cside.
